Erythrite, or Zeolitic Orthoclase, of flesh-red colour, underlies zeolites in cavities. It occurs pseudomorphous after Stilbite, Heulandite, and perhaps Prehnite. It is specially associated with Analcime, Prehnite, and Thomsonite, cmhny. It occurs at Bowling (Anal. 10) in Dum- bartonshire; at Boyleston, near Barrhead, at the Gryfe tunnel, near Greenock ; and at Berry Glen, in Ayrshire.

Not acted upon by acids. Microcline is in Scotland of much more frequent occurrence than is Orthoclase. It may be said to be the essential constituent of many granites and of most acidic gneisses and pegmatites. It exhibits the Microclinic structure in very varying development, and, generally, this is more apparent in the Microcline of those remarkable bands of granitoid rock [pegmatite] which traverse, in parallel courses, so many of the older metam orphic areas of Scotland.

The crystals are sometimes much distorted, cmmfby (Plate LIIL, fig. 1); cmmfbyxoo' (Plate LIII., fig. 2); czz'lyxoo' (Plate LIIL, fig. 3); cmm'lzz'yoo f (Plate LIIL, figs. 4 and 5); c m m' b z z f y (Plate LIIL, fig. 6); cmmbzz' yxoo' (Plate LIIL, figs. 7 and 8); cmm'lzz'yx (Plate LIV., fig. 9); twins cmm'lzz'yxoo' (Plate LIV., figs. 10 and 11), with the axis of revolution vertical, c and x nearly coinciding, and showing the com- position by sutures which show the two halves of the twin mutually to interpenetrate. These crystals are associated with Eadiated Cleave- landite, Fluor, Orangite, Thorite, Magnetite, Babingtonite, Sphene, Ilmenite, and Zircon. Towards the centre of the vein crystals of the Manebach type occur. Two crystals of huge size were found, one 15 J inches along & and c, 10 inches over &, 8 inches over c; the other 12J inches along & and c, 8 inches over b, and 6 inches over c. The simple crystals are c I x (Plate LIV., fig. 12) ; c I m m'zz' xy (Plate LIV., fig. 13) ; clmm' zz' xyoo' (Plate LIV, fig. 14), and twins of the last (Plate LV., figs. 15 and 16); of clzz' mm' xyoo' (Plate LV., fig. 17); clmm'xyo (Plate LV, fig. 18), sometimes with the face o alternately hemihedral ; clzz'mmf oo' x (Plate LV., fig. 19), with the faces z and o alternately hemihedral; and c I z z' m in' o o' x y (Plate LV., fig. 20). These deeper- seated crystals are associated with Ilmenite, Specular Iron, radiated Strontianite, and Quartz. The plagioclase felspar, which forms the corded structure of the above Microcline, appears from the analysis to be Oligoclase. It is itself striated parallel to the cleavages of the Ama- zonstone crystal. The angle of the latter is 89'43. Benin Laoghal.

This consists in all cases of a nearly simultaneous intergrowth of Microcline, or, rather, of cross-hatched felspar, with Quartz, the corded structure of Albite or Oligoclase being generally absent. The Quartz crystals have their main axes parallel to the faces c and b of the felspar, as if imbedded in parallel growth in a simple crystal of the Baveno type. The Quartz, through dominance of crystallising power, preserves the angles of its faces ; but as there has been a deficiency of material for the formation of solid forms of Quartz, hollow crystals result. The structure is also deficient as regards several of the faces of the prism, but hollow summits of the crystals are successively formed, the one within the other, as the compound structure is built up. As the deficient faces of the Quartz crystals are on one or other side which faces "b of the felspar crystal, sections of the felspar parallel to c show an imbedded system of crystals of Quartz, which resemble fish-hooks of more or less regularly increasing size (and common polarity) linked one within the other, the hook being turned towards I. Again, sections parallel to a of the Microcline, which sections cut the Quartz crystals at right angles to their main axis, show more or less numerous angular sections thereof, according as the deficient prism or the hollow summit of the crystals happens to be cut across. In all cases in Scotland where graphic granite is found in situ, it occurs in granite [ = pegmatite] veins, the material of which has solidified from the sides towards the centre. Almost all such veins show this graphic structure when sectioned parallel to the sides of the vein, and the structure is most minute at the sides. It is only very rarely that the Quartz protrudes from the ter- minations of the crystals of felspar. The whole circumstances seem to point to the silica which has crystallised having been that portion which has been present in excess of the quantity necessary for the formation of the felspar. In such rocks as exhibit this structure on a micrographic scale, a radiation of the Quartz from many solidifying points has taken place. In some of the huge veins in which it is found in Scotland, the Quartz crystals hold a parallel position over large spaces; while in others in which the felspar has concreted in huge rude crystals, there is a radiation of the Quartz, generally from a single point in each crystal. The great vein in Chaipaval, Harris, and those in and opposite to the islet of Stromay, in the Sound of Harris, are examples 10 SILICATES. of the first; the red vein near Cowhythe Head, in Banffshire, is an example of the second.

In its habits in Scotland Oligoclase presents itself as the very frequent associate of the corded felspar in granitic veins only in one locality (Coyle) is it found in another association; the evidence as regards it is perfectly definite. It also constitutes the bulk of the grey granite of Aberdeen ; this I find to consist of a great deal of Oligoclase, little Orthoclase, little Quartz, very small quantities of Muscovite, and a good deal of Haughtonite, such a compound as G. Eose calls granitite. The hornblendic gneiss of the Cape Wrath district frequently consists almost solely of a granular mixture of Oligoclase and Horn- blende. No one who has become familiar with the ever-recurring exfil- tration veins called crocus by the quarrymen which lace the grey granite of Aberdeenshire, will hesitate in considering the well defined crystals of the white felspar of these veins to be as thoroughly good a species as the accompanying flesh-coloured Microcline. A similar association with Microcline is also to be seen in the veins whether intrusive or exfiltration which occur in hornblendic gneiss, as at Eispond and Geodha na Seamraig. SILICATES. 15 ORKNEY.

Anal. 3. 840. Latrobite. Many authorities regard Latrobite as being a species distinct from Anorthite; others place them together. This is certainly ill-advised. Anorthite is a lime felspar, with only a trace of potash ; Latrobite is a potash-lime felspar. The classification of the felspars is essentially an alkaline one every consideration should make it so. Dana unites this with Anorthite from the quantity of its acid ; but it is doubtful if that quantity is the same as in Anorthite. Latrobite has different angles, and has much inferior hardness. The specimens I have were found at Dalnabo, in metamorphic lime- stone associated with Anorthite. There was very little of the mineral ; 1 FeO, -11. SILICATES. 21 from the appearance and hardness being the same as those of Rhodonite, it was taken for that species until the specific gravity was determined. The colour was pale rose-red, the structure fine granular, the lustre feeble, the hardness 5, the specific gravity 2'749. Two specimens from different parts of the quarry were analysed ; the first was pure, the second might not have been totally separated from Coccolite. Only one other locality of this mineral is known. 2. METASILICATES. ESi0 3 . Pyroxene G-roup. a. Orthorhombic Section. 85. Enstatite (323). MgSi0 3 .

Many substances occur in Scotland, which, from their mode of occur- rence, their situation, their appearance, that is, a gradation in their outward change, and from a corroborative alteration in their constitution when analysed, give rise to the conclusion that they have been formed by what may be termed a gradually-increasing serpentinous change from other minerals, of which Enstatite, Augite, Hornblende, and Olivine may be taken as the types. Those who wish to consider the details of such transmutation may consult a chapter on the subject in the Trans. Roy. Soc. Edin., xxviii. (1878). It is here merely necessary that, through their immediate relationship to Augite, the following analyses be given : 1 to 9 inclusive, Heddle, Trans. Eoy. Soc.

The appearance of the other was precisely that which might be expected in a massive Gyrolite. Large folia, of pearly lustre, and of a distinct sea-green colour, passed from all sides to the centre. Generally these folia were flat ; but here and there they were twisted and interwoven. But the toughness of the specimen threw doubt upon the mineral being Gyrolite, and the analysis, No. 4, left no doubt that the mineral in question was simply an exceptional form of Pectolite (Heddle, Trans. Geol. Soc. Glasgow, 1892, pp. 241-255). See also Analyses 5 and 6. A mineral doubtfully referred to Pectolite occurs in the north-west cliff of Askival, Eum. ARGYLLSHIRE.

Eatho, where Pectolite occurs filling what were originally large vapour cavities in a great sheet of Dolerite. It is of a pale greenish-grey in colour, with a silky lustre, and is excessively tough. Some of the cavities are not quite filled by the Pectolite ; hence the free ends of the aggregations sometimes assume a distinct crystalline form (Plate LX., fig. 1) which serves to show the isomorphism of the present species with Wollastonite. Analysis 12 was made from the ordinary fibrous variety, and Analysis 13 from the crystalline form. Pectolite occasionally occurs at Eatho also as an interesting pseudomorph after Analcirne. In the Dolerite quarries of Corstorphine it is not uncommon, and is compact and fibrous, and of a pale greenish-grey colour Anals. 14, 15$. It occurs, rarely, also in the basalt of the Castle Eock of Edin- burgh, in nodular masses, with a diverging structure, translucent, and crystalline, of a pale yellowish colour, and associated with Prehnite Anals. 16, 17. It is said to have occurred, in a weathered state, at Lochend, on the east side of Edinburgh ; also at Salisbury Crags (Taylor).

In acicular crystals in grey felspar-porphyry. Non-aluminous varieties of Amphibole tend to pass into fibrous varieties. The fibres of Tremolite are sometimes very long, and so loosely attached as to be separable by the fingers. When such fibres are flexible they are termed 'Amianthus ; when rigid, but tough, Asbestus ; and when rigid, isolated, transparent, and brittle, Byssolite. When these fibres become matted and entangled they form a fissile or schistose stone of great toughness termed Nephrite, being one of the stones used for the manufacture of axe-heads. Similar arrangements of crystals of Actino- lite form actinolite schist, which sometimes occurs in quantity entitling it to be regarded as a rock-mass.

Comp., essentially 18 Silica, 73 Thoria, 9 Water. Orangite and Thorite are thrown together because there is no ques- tion of their being one and the same substance: that which is called Thorite being merely Orangite in a state of greater hydration. Differ- ences of colour may be seen to pass into one another with the greatest abruptness in the same crystal, and that so precipitately, that the passage may be termed immediate. There are several localities at which there are more or less grounds for suspecting the occurrence of this mineral, but it has been definitely determined only at two. The first is the great boulder at Tongue, where it is found in lumps up to the 56 SILICATES. size of beans, both rich orange-yellow and black, rarely showing crystal- lisation. When definitely crystallised there, the form is that shown in Plate LXVIL, fig. 1. Its associated minerals here are so numerous that a list, arranged in the order of their occurrence from the outside of the vein which carries them inwards to its centre, may be given. These are Babingtonite, Fluor, Sphene, Allanite, the Thorite, Magnetite, Lepidomelane, radiated Cleavelandite, Ilmenite, Amazonstone, Oligoclase, Quartz, Specular Iron, Bhreckite. This occurrence, seeing that this is a huge erratic, though almost unquestionably from Beinn Laoghal, cannot be regarded as other than unsatisfactory. The second locality where it occurs is in rude veins which protrude from the face of the great cliff of Beinn Laoghal, Sgor a' Chonais-aite. Here it occurs in crystals showing four different forms. Two of these show only pyramidal faces, in which the angle of the pyramid seems to depart so little from that of the regular octahedron that it cannot be the primary p face which is here disclosed. The second form is the square prism terminated by the pyramid as shown in Plate LXVIL, fig. 1; next, and this crystal is the most common, is the form depicted in Plate LXVIL, fig. 2 ; and lastly, there are two distinct octahedra, about half the size of peas, which, as before mentioned, seem to be the regular octahedron. The following difficulties stand in the way of the definite determination here. There is, firstly, the objection to the destruction of the specimen, and, secondly, the fact that the surfaces of both crystals are much pitted, and so dull that they would afford no reflection. But the fracture, both of the pyramidal and of the octahedral crystals, is conchoidal, the lustre pitchy, and the colour deep brown. In addition to their being non-mag- netic, there is no risk of here mistaking Magnetite for whatever mineral these octahedra may be, as the Magnetite here is blue-black, with distinct cleavage, and hackly fracture. And, again, the internal structure of the crystals which occur in these two irreconcilable forms is no more like that of a pseudomorph in the one case than it is in the other. The octahedral crystals do not resemble Pyrochlore. The pyramidal mineral is soluble in hydrochloric acid, with separation of silica; and the orange-coloured solution gives a copious ruddy precipitate with ammonia, which, taken along with the form, is sufficient to determine the tetra- gonal mineral as Thorite. At its second locality the mineral is, next to Amazonstone and greasy-looking Quartz, the most frequently-occurring substance in the veins, but it is usually in particles too small to be broken with advantage for collecting it. The associated minerals at this second locality are Babingtonite, Topaz, Eubinglimmer, Galena in small specks, and Sphene. SILICATES. 57 Danlurite-Topaz Group. IDS. Topaz (397). (Al(0,F 2 ))AlSi0 4 .

At the north-west end of the Mugdock tunnel, in dark greyish-green mammil- lations, associated with plates of Native Copper. DUMBARTONSHIRE. Near Frisky Hall (Bowling quarry) (Jameson), in large quantity, chiefly in two great veins which traverse the quarry from west to east ; but also occasionally in isolated druses in the north part of this quarry ; comb, cmab (Plate LXXI., fig. 2). The Prehnite is nearly persistent throughout these veins, though occasionally, where the veins are not so strong, it gives place to one or other, or to several, of the other zeolites mentioned below. Its character at different parts of the veins changes materially. Where the vein-structure is most marked, the Prehnite is in sheets, flat, fibrous, and of palecolours, and has indis- tinct terminations Anal. 3. Where the veins break up into lines of SILICATES. 71 more or less separate druses, the colours become finer, the mammillations more prominent, and the individual crystals more isolated, and so more perfectly formed. Occasionally the association of one or more of the other zeolites seems also to effect this more perfect assumption of definitely crystallised terminations. The associated minerals, which are generally in the smaller offset veins, are Analcime, Thomsonite, Natrolite, Laumontite, Harmotome, Barytes, Edingtonite, Chabazite, and Stilbite. The two last named are always in separate veins. The general combina- tions of the crystals in the veins are calms and cabmsnv (Plate LXXL, figs. 3 and 4). S. G., 2, 885 (Haidinger). Very frequently the pale green fibrous Prehnite passes at one end of the fibres into milk-white solid Pseudo-Analcime. The structure of this is a mass of matted fibres at the faces of the crystals, while their usually hollow centres show mammillations of a green or, rarely, of a bright yellow Prehnite. The colours of the vein-Prehnite are, at the west end of the veins, brownish-white ; at the central portions, of a vivid light green ; while at the east end, when the colour departs from the usual dull green, it is either bluish-white (with the surface of the mammilla- tions so smooth as to have a chalcedonic appearance), yellow-green, or sulphur-yellow. In the cavities the crystals are generally isolated, calm (Plate LXXL, fig. 2), and the associates, if there are any, are Natrolite and " Prasilite " (or crystalline Saponite). Dumbarton Eock, with capillary Mesolite, in basalt (MacCulloch) Anal. 5, 5a. In Cochno Burn (Jameson). Near Loch Humphrey (Jameson). EDINBURGHSHIRE.

At Hartfield Moss (Jameson), waxy-white, opaque, and radiated, associated with Cluthalite and Analcime, not infrequently assuming the form of the latter (Greg) Anal. 7 ; grey in colour, and, in appearance, like Chalcedony, associated with Saponite. Also crys- tallised, cm ah At Bishopton tunnel (Jameson). Some specimens, associated with sheafy Thomsonite, Galactite, and Calcite, are perfectly botryoidal, each grape- like group of crystals being only just in contact with those adjoining such as these are bright green in colour. Others, associated with Greenockite, are in spheres, imbedded in a wackenitic paste. Eare specimens, which are associated with Datolite, though of paler colour than these latter, are in exquisite groups of fasciculitic tufts and spheres. Harmotome, Analcime, and Galena are here rare associates. At Boyleston quarry, Barrhead, in large quantity, and solely in mis- shapen druses in the harder portion of a porphyritic basic lava. Free crystals are very rare. The associates are Native Copper, which is frequently disposed in filaments and needles between the brushes of Prehnite, and which colours them brown-red, Analcime, Natrolite, Thomsonite, Malachite, Kubinglimmer, and variously and finely- crystallised Calcite. The Prehnite is usually of a pale green colour, but isolated hemispheres occur, which are of a fine yellow colour, and are sometimes disposed over, or among, the crystals of Analcime. Earely, some druses contain lustrous groups of an exceedingly light green and milk-white colour. Mickle Cloak, Lochwinnoch, in dull, radiated, dead- white crystals (Montgomery). AYRSHIRE.

Gyrolite was unquestionably observed and recognised as a new mineral species quite independently by MacCulloch, Haidinger, Giesecke, and Earl Compton ; but the mineralogical science of their days was not sufficiently advanced to enable them to individualise it as a species. MacCulloch (Trans. Geol. Soc., vol. iii.) writes of it : Mesotype one variety " is disposed in a radiated or rather in a ramose manner, in fine fibres possessing the peculiar lustre and softness of the finest white pulverulent Talc. ... In a third instance, which I observed near Loch Eynort, a mass of globules of solid radiated Mesotype, very much resembling some of the oolites, is intermixed throughout with farinaceous scales of the same substance, having the greasy aspect and lustre already described. In speaking of this substance, I have, according to common usage, ranked it with the Mesotypes ; it appearing to have been thus placed, partly because it is found associated with them, and partly because of the theoretical views which have been held respecting its origin. It will be for mineralogists of more authority to consider whether it does not deserve a separate place as a species, the question is evidently of a nature not to be determined by geometrical analysis, as far at least as the varieties already found extend; and the delicacy and uncertainty of unassisted chemical analysis in questions of this nature are far too great to tempt us to seek a new place for it by this kind of investigation." In the fifth volume of the Trans. Geol. Soc. London, again, we find SILICATES. 79 Earl Compton, in the year 1821, giving, among a list of minerals which occur a little way inland, and behind the farm-house of Carsaig, " Anal- cime, a foliated Zeolite" In volume vii. of the Edinburgh Journal of Science, it is stated, at page 19, that Giesecke discovered what must have been Gyrolite, terming it " micaceous Apophyllite or a sub-species of Apophyllite " ; and giving as its locality Nia Kornak, in Disco, where it occurs in vesicular cavities in basalt, associated with Apophyllite, and Mesotype in one specimen with Chabazite and Levyne, of the specific gravity of 2-382. In the same volume, of the date 1827, in a paper in which Haidinger considers the varieties of Mesole, he writes : " Though even now I cannot pretend to offer a perfect description, the more accurate indication of the regular forms being yet a desideration, yet the crystals which I have examined of these new varieties are such that the place of Mesole in the system of Mohs may be fixed with precision." After excellent descriptions of typical globular varieties of undoubted Mesole from the cave of Naalsoe, he thus describes this species : " VI. Reniform groups with a single cleavage: very bright, pale yellowish-grey, from Ma Kornak, Disco. This new variety shows a very great resemblance to certain kinds of Apophyllite, so much so, that Sir Charles Giesecke, who discovered them, was induced to consider this as a particular sub- species, terming it the micaceous Apophyllite." The seventh specimen is described as " occurring in plates, which have a bright pearly lustre, and thin cleavage planes ; the whole aggregate resembles, in no small degree, crystallised spermacetie form part of the inside of a geode at Karartut, near Godhavn, Disco colour somewhat yellowish; eighth specimen, large, aggregated, uniform shapes, colour yellowish-grey, cleavage easily obtained, and the laminae show some elasticity when you attempt to separate them," also from Nia Kornak, in the Umanakefjord, Disco. Haidinger remarks upon its perfect simple cleavage, its marked pearly lustre. u Its specific gravity being above 2*3, is much more considerable than that of either Stilbite or Heulandite, which hardly ever exceed the limit of 2-2, an immense difference in species whose specific gravity is at the same time so inconsiderable and so constant as in the genus Kouphone Spar. In this property it nearly agrees with Apophyllite, but is readily distinguished in its crest or fan- like aggregations, the like of which never occur in Apophyllite, yield also a good empirical mark, although the crystals hitherto observed are too small, or, rather, too thin, to allow of an exact determination. In allusion to these aggregrated groups and the kind of fracture depending upon it, I propose Flabelli- form Kouphone Spar as the systematic denomination of the species, the first varieties of which were described by Berzelius under the name of Mesole." [The author has slightly modified Haidinger's phraseology.] 80 SILICATES. Haidinger adds : "It is worth noticing that this species, when it is associated with Stilbite or Apophyllite, will always form the lowest stratum immediately adjoining the basaltic, or amygclaloidal, support in the cavities of which it is deposited." In this paper of Haidinger's we have a retrograde step, for though he clearly separates the mineral from Apophyllite, yet he does so at the cost of associating it with Mesole, a substance from which it differs, both physically and chemically, to a still greater extent than from Apophyllite. 123.

Double refraction weak; generally positive. Unbroken crystals in polarised light exhibit a beautiful tesselated struc- ture, of which the tesselee have curvilinear outlines, and differ much in form. No water lost by heating to 100, nor by exposure over sulphuric acid. All the water that is driven off at temperatures under 300 F. is reabsorbed; but only after very prolonged exposure to moist air. Werner found that Apophyllite was soluble in water at 180 to 190 C. under a pressure of from ten to twelve atmospheres. Bunsen found that at all the ordinary temperatures not a trace is soluble under pressures ranging from twelve to seventy-nine atmospheres. In the closed tube exfoliates, whitens, and yields an abundance of water, which affords an acid reaction. In the open tube, when fused with salt of phosphorus, often gives a fluorine reaction. B.B. it exfoliates, colours the name violet through the presence of potash, and fuses with intumescence to a white blebby enamel ; with salt of phosphorus yields a skeleton of silica. Fusibility = 1-5 of Kobell's Scale. In powder it is easily soluble in acid, leaving a slimy silicious residue ; but if it has been previously exposed to a red heat then it is decomposed only with difficulty.

We find it occurring in the intrusive dolerites as well as in the contemporaneous basalt lavas associated with the Lower Carboni- ferous Eocks of the Basins of the Forth and Clyde. It is also associated with the basalt lavas of Tertiary age, occurring in the Western Islands of Scotland. It is found, rarely, in both large and small crystals, associated with Elaterite, in one of the limestones interbedded with the Lower Carboniferous basalt lavas. It likewise, formerly, was found at Strontian, in the vein which lies between the granite and the gneiss this mode of occurrence being similar to some on the Continent. Apophyllite would appear to be the very last zeolite to separate and solidify in drusy cavities ; and it does not seem to affect many associates. At Eudha nan Clach, in Skye, where there are some druses which contain four zeolites along with Calcite, it holds itself apart, and appears only in cavities per se. It seems also to be peculiar as regards these associates confining itself almost entirely to the company of Gyro- lite, Pectolite, and Prehnite minerals which may be said to fringe the borders of the class of the true zeolites.

Figs. 7, 8, and 9 present very unusual de- velopments ; and it may be remarked that an apparently re-entering angle on the faces t and s of the Heulandites from Ben More raises some doubt as to the primary form. In amygdaloidal eruptive rocks which contain free zeolites and at the same time much Calcite, minute crystals of red Heulandite generally line the druses. Such crystals also occasionally form the inner part of the lining of Celedonite which coats the vapour-cavities in which Agates of both the ordinary type and Moss Agates occur. 127.

The Prochlorite from Beinn Dearg, and that from Girdleness (Analyses 2 and 8, above), and the Clinochlore from Dunoon and Bute (Analyses 5 and 6, above), which are all highly ferriferous, approximate in composition to Aphrosiderite, and may be referable to that not-very- well-defined species ; but it would seem more expedient to exclude from the designation those chlorites in which a considerable proportion of the ferrous oxide is replaced by magnesia (Currie).] 153.

Varieties : Many species have been made out of Serpentine, differing in structure (massive, slaty, foliated, fibrous) or, as supposed, in chemical composition, and these now in part stand as varieties ; all would seem to be produced by an alteration of other substances. 1. Chrysotile. Delicately fibrous, the fibres usually flexible, running transverse to the veins, and easily separating; lustre silky; colour white, golden-yellow, olive-green, brown. G. = 2'219. Often constitutes seams in Serpentine. It includes most of the silky Amianthus of Serpen- tine rocks and much of what is popularly called Asbestus. 2. Picrolite. Columnar, but fibres or columns not easily flexible, and often not easily separable, or affording only a long splintery fracture ; colour dark green to mountain green, greenish, grey, and brown. 3. Marmolite. Thin foliated ; the laminae brittle but easily separable, yet graduating into a variety, in which they are not separable. G. = 2-41 ; lustre pearly; colours greenish white, bluish white to pale asparagus green. 4. Precious Serpentine. Generally short and brittle in structure ; oily lustre, rich green and red colours, with opaline reflections, translucent, but sometimes in ramifying veins passing to white and opaque. 5. Bastite, or Schiller Spar, is Enstatite (Hypersthene), altered more or less completely to Serpentine. 6. Williamsite. A lamellar Serpentine of apple-green colour, with H. = 4-5. 7. Common Serpentine. Coarse and earthy, of blotched and variegated appearance, more resembling a rock mass. 8. Pseitdomorphous Serpentine. Shows crystalline faces or outlines. Analyses 1-8 by Heddle, Min. Mag. and Trans.

Common Serpentine. This often forms great beds, or even mountain masses. It is a mix- ture of all the foregoing varieties, together with, probably, some Dewey- lite, Hydrophite, Pyrosclerite, or Kaolinite. It is also frequently veined with Dolomite or Calcite, and is studded with partially or completely pseudomorphosed crystals of Olivine, Enstatite, Sahlite, Actinolite, Nephrite, Chromite, or Picotite, and even felspars. These (varied con- stituents) often mottle it with red, green, or white, thereby giving it the aspect of a porphyry. The names Serpentine, Ophite, and Lapis Colu- brinus, refer to the serpent-like markings displayed when it is cut and polished; it is then, sometimes, improperly called Serpentine marble. This common Serpentine occurs in Unst (Anal. 15) and Fetlar, as the matrix of Chromite. Usually of yellow colour. SHETLAND. Unst and Fetlar. Several beds of Serpentine diverge like the blades of a fan from a point lying to the south of the last of these islands, and pass northward. The most westerly traverses both islands ; the two next in order traverse Fetlar, touch the islets Urie Lingey and Daaey, but do not reach Unst. The most easterly forms a large mass in Fetlar, the whole of Haaf Gruney (Anal. 12), and the promontory of Mu Ness in Unst. These beds are associated with lime- stones, gabbros, and gneissic schists. Mainland. A bed which appears first north of Ollaberry, crosses the heads of Quey Firth and Colla Firth voes, and reappears in Fethaland at Pundy and Klebber Geos. Other localities are the south-west extremity of Bixter Voe, Hillswick Ness and the south-west of Scousburgh, on the shore. INVERNESS-SHIRE. In Glen Urquhart, above Polmaily, in association with limestones and margarodite (Muscovite) schists. HEBRIDES. Lewis, at Loch Thamanabhaidh (Nicol). Harris, Scalpa Island, at Eilean Glas. Nearly crossing Harris from Scara Eudha to the Dun of Borve, north of Loch Langavat. BANFFSHIRE, ABERDEENSHIRE, and PERTHSHIRE. At Portsoy; two beds show themselves to the west of the town ; a series of thin beds in and on the west shore of Durn Bay, and two more massive ones near Cowhythe Head. These traverse in a S.S.W. course the counties of Banff, Aberdeen, and part of Perth, as two beds, sending an offset which forms a third about the Hill of Noth to the east ; this appears at several points, and passes into the sea north of Aberdeen. All seem united as far south as about Huntly, appearing on the east side of a quartz range, as at Damhead, near Durn Hill, Fordyce, Lurg, and Knock SILICATES. 133 Hills ; at Limehillock, near Grange, and west of Eothiemay station. The several points at which the more westerly branch is now seen are at the Hill of Milleath, Drumhead, near Euthven, the Sockach [? Succoth] Hill, south of Glass, on the Deveron, and skirting its west bank upwards at Craigdornie, Craig luie, above Shenwell, Blackwater Lodge, and west of Creag an Sgor. A great mass forms Greer Hill of Strathdon ; it is again seen at Dulnein, on the Dee ; at Braemar, near the Dee ; and, according to MacCulloch, in the Eye Forest. The central band shows itself at the Eed Craig of Ehynie, the Hill of Tombhreac, in Auchindoir, at several points near Eedford in the Cabrach, on the Kindy and on the Deskry, between Morven and Cul- blean, in large mass at the Coyle Hills, near Ballater, and at Little Kilrannoch, at the head of the White Water, a branch of the South Esk. The eastern branch appears at Leith Hall, at Chapelton and Premnay, at Bourtie, Barra Hill, and Forester Hill, near Meldrum, in large mass at Belhelvie, and, lastly, at the Black Dog Eock, 5 miles north of Aberdeen. The igneous rock which appears here, and again in the vicinity of the great fault which separates the Old Eed Sandstone from the northern schists, shows itself at several places as Serpentine ; as at Cortachy Bridge, Balloch on the Carity ; near Barry, Hill of Alyth, and near the limestone at the south end of Loch Cluny : probably it is the same as appears north of Balmaha, on Loch Lomond. Near Kinnordy, in Forfar, and at Balmaha, it contains altered crystals of Enstatite. AYRSHIRE. At Balhamie Hill, near Colmonell, with Pseudo-En- statite, and near Lendalfoot, north of Ballantrae, Carlton Castle (Greg). Serpentinous Marbles. "Primitive limestones," with included patches or nodules of Ser- pentine, which have been derived from the serpentinisation of Malacolite and Sahlite, for the most part, and, rarely, of Olivine, occur in SUTHERLAND. At Ledbeg, colourless, and sulphur-yellow, rarely black. EOSS-SHIRE. At Totag and Beinn Chuirn, Glenelg, grey, yellow, and slate-blue. HEBRIDES. Skye, in Strath, dull yellow. Harris, at Eodil, grey, lona, at Port na Curaich, yellow and green. Port an Duine Mhairbh, yellow and grey. Tiree, Ballyphaetrish. INVERNESS-SHIRE.

Certain substances whose nature has not been sufficiently deter- 134 SILICATES. mined, and probably in themselves mixtures, somewhat like potstone, have been assigned to Serpentine : as that of a dull-green colour, which fills rents in Logan rock at Ullapool and elsewhere, and which appa- rently passes into Epidosite. The value of Serpentine as an ORNAMENTAL STONE depends upon an admixture of the more precious varieties with their varying colours in vein and blotched arrangements, still more diversification being at times imparted by admixtures of Steatite, Nephrite, Marmolite, Asbestus, and Chlorite. The Unst ornamental stone is rarely fine. The most common variety is dark-green, with pale yellow-green veinings. In small masses a finer stone occurs north of Swinna Ness. This has pale-green crystals of softening Enstatite, impacted in a deep-green base of Precious Ser- pentine. The Haaf Gruney rock is pale purple, with greyish-yellow bands. That of Scousburgh is dark-green, with a network of pale yellow-green to white. The more westerly of the Portsoy beds of Serpentine is highly variegated, and, though difficult to obtain in large blocks, is probably the most beautiful and most variegated known. It was long wrought by a French company, and the pillars of the great Hall at Versailles are made of it. The admixture of colours of all tints except bright blues is beyond number. A stone with a dark green basis sprinkled with bright red pseudomorphs of Olivine, or of Augite, and pale-green markings, pre- dominates towards the west. A pale green nephritic base with interlacing veinings of dark-green Precious Serpentine, and nodules of pale olive- coloured Steatite, occurs in the centre. The Precious Serpentine is some- times studded with blood-red spots. Verdigris-green, with blue-black dendritic markings, is found at the east. The second vein, formed apparently by alteration of gabbro, is greyish-green, with mottling of dark greyish-blue. Lavender, rich brown, green and white veins of Marmolite, pervade the first two varieties. One vein, below water, in the East Bay, affords blocks of dull-green, mottled with brown, and is traversed by broad bands of fawn-yellow. That of the Hill of Tom- bhreac has a plicated intermixture of dark- and light-green, with white. Its appearance suggests a rock of gneissic structure as its origin. The Serpentine of Glen Kindy and Culblean is similar to that of Scousburgh. The rock at Lendalfoot is occasionally banded dark- green, mottled pale-green, and cream-colour, in alternate bands of an inch in width. Certain of the Serpentinous Marbles rank as ornamental stones. That of Glen Tilt is sap-green and sulphur-yellow, mottled with white. SILICATES. 135 The Tiree Marble is flesh-red, with imbedded granules of bright-green Sahlite, in every stage of alteration into Serpentine, with occasionally large lustrous crystals of dark Diallage. Other localities than these yield ornamental combinations, but in masses large enough only for inlaid work. At Beinn Chuirn, in Glenelg, snow-white with blue and green. In Tiree, white with sulphur-yellow ; and Ceann a bharra, and at Ballyphaetrish in Tiree ; to the east of which is a white marble, with lead-blue enclosures. At Leslie and Leith Hall the Serpentine is fibrous, as if formed from Amianthus. It is greyish-green, with grey and dark-blue specks, and is made into snuff- boxes, etc. 155. Totaigite (481). [Dr Heddle at one time regarded a yellowish-brown substance which occurs in the metamorphic marble of Totag, Loch Alsh, and Beinn Chuirn, Glenelg, as a new mineral species, and described it as such (Trans. Roy. Soc. Edin., xxviii. 455, 1878). There is reason to believe that he sub- sequently abandoned this view. The mineral is now referred to Forsterite. His analyses gave : Sp. Gr.

The rock of the east side of Scuir Dearg, Skye, rarely has minute cavities with an intensely-blue substance, in structure resembling Saponite. The following localities assigned to chlorite doubtless refer to Saponite. " With quartz in a felspar dyke traversing grey wacke and conglomerate, at Carolside on the Leader." " In amygdaloidal porphyry at Muirhouse law, 2 miles south-east of Maxton, Eoxburghshire." The following localities assigned to Steatite doubtless also refer to Saponite. Lanarkshire, at Phillipshill quarry, " finest in Britain, with zeolites." " Berwick. Dunse, near Cumledge House, in a dyke in the bed of the Oxenden burn, in beautiful crystals, a mineral like Steatite in veins, with zeolites." " In thin veins in the felspar porphyry of Lam- berton Hill, quarried near Nunlands." A study of the mode of association of Saponite with the minerals which occur along with it shows that the Saponite of the volcanics of Old Eed Sandstone and Carboniferous ages has been the substance last deposited in their vapour vesicles ; while that of the volcanics of Tertiary volcanics has been the first. The earliest notice of so-called Saponite gave Cornwall as its locality, and Cronstadt, Klaproth, and Kirwan considered the mineral there occurring as belonging to this species. An analysis of an exceedingly fine specimen specially sent the author by Professor King, of Belfast, showed that it was a slightly weathered vein of white precious Serpentine. A graver and more persistently indulged in error consists in petro- logists assigning the ever-recurring Saponite of decomposing basic and SILICATES. 143 sub-basic eruptive rocks to Chlorite. This is still, by many petrographers, even by those occupying positions which confer the widest experience, referred without hesitation to that mineral. This error was pointed out in the year 1879 by the author, when it was shown that Chlorite and its congeners were confined absolutely to rocks which had undergone dynamo-metamorphism (see Trans. Eoy. Soc. Edin., vol. xxix. p. 101). On the other hand, Saponite, and what may be regarded as its congeners, are equally absolutely confined to eruptive rocks, which present these minerals as the resultants of hydro-thermal alteration. The prominent feature of the alteration is the pronounced hydration which accompanies the chemical change. The so-called " viridite " of the Car Craig Rock and the " Chlorite " of the Kinghorn melaphyre, figured in plate xxii. of Teall's British Petrography, are, in point of fact, ordinary typical examples of investing and vermicular Saponite such vermicular forms the employment of a higher magnifying power resolves into piles of crystals of a rudely hexagonal form. Though generally devoid of definite crystalline form, Saponite is possessed of no little interest, in virtue of the varieties of its aspect, its very large content of water, and the singularity of the manner in which it comports itself therewith. No mineral presents itself under more varying forms than this, as is seen in the white, clotted-cream-like Saponite of Quiraing the fibrous, amianthoid, lustrous, sap-green veins of Craigs railway cutting, in Forfar the brown, nodular, bole-like, con- cretionary masses of some of the so-called " Bowlingite " the blue-grey mottled bands, which floor zeolitic cavities, with much the appearance of Naples soap the diversely coloured, onyx-like variety, with its bands of vivid red, which is rarely seen in the rocks north of the Echoing Crag, Quiraing and the deep green, fan-like, lustrous rosettes of the "Prasilite" of Bowling. This solid stone contains one-fourth of its weight of water. That the whole of that fourth exists in it as a liquid, or in an ordinary hydrating condition, cannot be for a moment supposed, A certain portion must be playing the part of a base. But the functioning of the solid part to the large percentage of water given off at a temperature of 212 F. is peculiar in itself ; about one half of that quantity being given up at the ordinary temperature of the human body, and this same amount is reabsorbed by it, if it be placed in a moist atmosphere, so that the total water content ultimately is identical with that of its first composition. Now this extraordinary mode of functioning, as regards percentages so high as from six to seven, may come even to affect to a certain extent the humidity, if not the climate, of a locality, if any great quantity of the mineral is present in the rocks ; and there is a locality which, though not of great 144 SILICATES. extent, is probably so affected. The peculiar vibration which is observed when we bring the eye close to the ground on an exceptionally warm day, in a locality of unusually brilliant exposure, is due to the rise of currents of air heated by contact with parts of the rocks affected by such exposure. Now a district of some miles in extent, which lies between Dumbuck and the Lang Crag, in Dumbartonshire, consists of a rock of which perhaps one-third is Saponite of a very dark green or almost black colour. The amount of atmospheric vibration there seen in the circum- stances above detailed is so great as to leave no doubt that large quantities of aqueous vapour are here ascending along with the currents of heated air. In dry, sunshiny weather the air over this district must be thus rendered more humid ; while in moist weather, in virtue of its power of reabsorbing the lost water, the atmosphere must be, to an equivalent extent, rendered less humid. FERRITE. 1 Wallace Young, quoted by Heddle, Min. Mag., v. 28 (1882). Heddle (ibid., vii. 134, 1887). An alteration-product of Olivine in the basalt lavas of the Glasgow district, chiefly between Gleniffer Braes and Boyleston. It frequently retains the form of the Olivine crystals, but has cleavages nearly equally eminent, parallel to both a and b of the original Olivine crystal. It is soft, greasy to the touch, and of high tinctorial power, of a deep red to chocolate brown colour. The air-dried mineral loses 3'83 % at 212 F. An analysis by Dr Heddle (Min.

Bole cannot be regarded as having any claim to be considered a simple mineral ; nor is it easy to say to what species it should be referred as an impure variety ; for that it is a mixture of two or more minerals there can be little doubt. Probably the substance to which the term has been generally applied comes nearer to Saponite than to anything else. It SILICATES. 149 is probably the fact that all the substances to which the term has been applied in Scotland have been associated with basic eruptive rocks usually with basalt lavas. Of such definite application we do not find, perhaps, so many in Scotland as in England. We find Greg (p. 442) giving as localities " in sandstone at Quarry Wood, Morayshire, and Bridgehouse in Peeblesshire," and the present writer has heard the name applied to some of the brown Saponite of Bowling ; the fact of the sub- stance falling to pieces in water seemed to be its only characteristic property.

This singular substance used to find a place amongst the varieties of Hornblende. How previous authors, and how Dr Thomson, and others who analysed it, could place a substance which contained 23 % of water along with one which is anhydrous is not easily explained. Had these analysts gone into the detail of ascertaining the amount of that water given off at 212 F., it would have been still more unaccountable. It is a substance peculiar also both as regards the features of its occurrence and the wide range in lithological character of the rocks in which it is enclosed. As regards its appearances, we find it assuming the character of felt ; SILICATES. 153 in leather-like leaves; resembling cork or the roots of trees; forming large sheets, which, in virtue of its altogether unrivalled toughness, would have served for the targe of a Highland warrior ; in tufted filaments with zeolitic associates ; a scum which appears to have sedimented from suspension in a muddy liquid, and simulating the very finest floss silk. As regards the parent rocks, these include Serpentine, Granite, Con- glomerate (Old Eed), Andesitic lava, Basalt lava, associated with Gneiss, and in Ordovician Argillites. Its associated minerals accordingly are equally diverse. Those with the limestone matrix are Pyrites, Calcite, and Steatite ; those of the Andesites are Calcite and cockscomb Barytes (the crystals of which penetrate the Pilolite), at one locality ; Analcime at another ; and Natrolite, Barytes, and zeolitic Quartz at a third. Those of the basalts also comprehend a wide range of minerals Analcime, Scolecite, Stilbite, Chabazite, Mesolite, Laumontite, and Calcite. [173. Pihlite.

Collie, " On Some Leadhills Minerals," Journ. Chem. 8oc., Iv. p. 94, describes a mineral from Leadhills under the above name. It occurs in black botryoidal masses, and is unlike either Pyromorphite or Vanadinite in appearance. The fracture is uneven or conchoidal; it fuses easily before the blow-pipe, leaving a brown granule, which, when broken, shows a crystalline structure. It dissolves readily in hydrochloric acid when warm, and leaves a slight residue of a brown colour, which consists chiefly of an oxide of iron. Two analyses were made : Sp. Gr. 1. 6-9-7-0 2.

Principally at Garbh Eilean, the largest of the Shiant Isles, where the writer of this note has found it on the north shore, close to Sgeireaii a' Bhaigh. It occurs in the form of discoidal aggregations of radially- disposed acicular crystals, coating the joints of one of the Middle Jurassic clays, close beneath the base of a thick intrusive sheet of dolerite of Tertiary age, and highly indurated by the contact. An orbicular structure has been developed in the clay by the contact metamorphism, and a note on one of the specimens in the Scottish Mineral Collection states that the author regarded the Wavellite as forming the basis of the spheroids referred to. In the article " Mineralogy," in the 9th edit, of the Encyclopaedia Britannica, the author refers to this species a mineral occurring in the form of contiguous groups of thin discoidal aggregations of acicular crystals, which coat the joint faces of one of the andesitic la*vas of Devonian age in Glencoe. A specimen of the mineral referred to was placed with the Wavellites in the Scottish Mineral Collection ; but the author left no further information regarding it than the statement that the specimen is in the near neighbourhood of Withamite. Wavellite usually occurs on the joint faces of fossiliferous rocks of argillaceous composition, which have been affected by contact metamorphism (J. G. G.).] OXYGEN SALTS.

[Torbanite, although related to Cannel Coal, has a very nearly uniform composition, according to all analyses thus far made, excepting that of Miller, and this composition is like that of Bathvillite, but with less oxygen. It corresponds very nearly with the formula C 40 H 68 2 . 25 = carbon, 8219 ; hydrogen, 1148 ; oxygen, about 6'0 ; nitrogen, T37 = 100 : excluding the nitrogen, C., 82-28 ; H., 11-54; 0., 6'08 = 100. Less than 1J % of Torbanite is soluble in naphtha (Fyfe). From Dana, Syst. Min., 6th ed., p. 1009. In Upper Carboniferous rocks, at Torbane Hill, Bathgate parish, Linlithgowshire. " It frequently occurs in seams of some considerable size, and always in the neighbourhood of coal, sometimes in immediate contiguity with it, but at other times . . . separated from it by a layer of fireclay." The colour varies from tan colour to sooty-brown. Its fracture is dull, and often conchoidal, like that of cannel coal, and it is translucent in thin section. "Its specific gravity ranges from 1'2 to 1-3." Its streak varies in colour from saffron to umber, and is usually shining, and very similar to that afforded by oil shales. " It is tough, and not so brittle but that thin sections may be made of it." It possesses considerable elasticity, and, " when struck by the hammer, it emits a dull sound. The remains of plants, especially of Stigmaria, are of constant occurrence, and can be distinguished by the naked eye without difficulty. . . . Under the micro- scope it is found to consist of masses of a yellow material, some being of irregular figure," spores and spore cases, " others more or less rounded, embedded in a granular matrix, which vary in colour from a yellowish- brown almost to a black." (The sections in quotation marks are from a paper by Professor Queckett, On the Minute Structure of . . . Boghead Cannel Coal, pp. 34-36, 1853 ; the others by J. G. G.) Dr Eedfern, Micro. Journ., iii., and Rep. Brit. Assoc., 1854, states, regarding its mode of occurrence : " It has a layer of cement stone immediately above it, half an inch to two inches in thickness. Above that is a bed of shale, varying in thickness up to four feet. Immediately below the bed is a stratum of fireclay, with occasional ironstone balls, about two inches thick, and very full of impressions of plants. Under that is a layer of good bright-looking coal six inches in thickness.

IN the course of printing the Mineralogy of Scotland, it has been found that one or two species have been accidentally overlooked. Besides these, there were some few other species regarding the validity of which, there is reason to believe, the author's views had changed. Others were of doubtful authenticity as occurring in Scotland. Then, again, during the last three years, a few species have been added to the Scottish list, chiefly by the officers of the Geological Survey. To these species must be added those already known as Scottish, which have lately been dis- covered in new localities. Finally, the Editor has been continuously at work during the last three years at the arrangement of the Scottish Mineral Collection in the Edinburgh Museum of Science and Art. In the course of this work he has determined a large number of forms, and has made drawings of several hundred combinations. The crystals so drawn are all indicated by blue pointers, are all duly registered, and are placed so that the public can easily study them, and the drawings are exhibited in contiguity to the specimens. The results of some part of this work are given in the notes that follow, in which the symbols employed are all Dana's (sixth edition), and the Museum reference numbers are given in prefixed brackets. The Editor is responsible for all the following statements, except where it is stated to be otherwise. EDINBURGH, November, 1900. Diamond (1). Localities. On the ticket of a specimen found by Dr Heddle, and given to Mr Thorns shortly before his death, and now in Mr Thorns' cabinet, is as follows: "This specimen of Aventurine, from a lake 3 miles to the north-east of Ben Hope, Sutherland, contains, besides the red mica, red Zircons, and either colourless Garnets or Diamonds." VOL. II. N 1 94 SUPPLEMENT. In handing this specimen to me, however, Dr Heddle remarked that in his own mind he felt confident that these small crystals were Diamonds, as they had certain optical properties which no other mineral he knew of possessed. Although not alluded to in the manuscript of this book, it is judged advisable to place this on record (A. Thorns). Graphite (2). Close examination of the minerals occurring in the various meta- morphic limestones occurring amongst the Highland Schists and Gneisses has brought to light the fact that scales of Graphite are present in nearly every case. A conspicuous example is presented by the limestones of Glenelg, described by Mr Clough (Q.J.G.S., Iv. 372). Probably some, at least, of the supposed Molybdenite recorded from the metamorphic marbles of Scotland will prove to be really Graphite. Sulphur (3). Crystallised Sulphur has been found as a product of the spontaneous combustion of Lower Carboniferous shales containing Pyrites, at several places in Scotland. It would seem to be almost as much entitled to rank as a native species as most of the Nitrates and Hydrous Sulphates. Bismuth (11). This is mentioned by Greg, Brit. Min., 378, as occurring formerly at Alva, in Stirlingshire ; reticulated and associated with Erythrine. Gold (13). Small specks of Gold have lately been detected in various eruptive and metamorphic rocks from Scottish localities. Probably, in a very sparsely distributed state, its occurrence may prove to be much more general than has hitherto been supposed. Greenockite (68). The Editor has examined and drawn a large number of crystals of Greenockite, almost the whole of which are characterised by complex oscillatory combinations of the prism (1010) with various pyramids, chiefly (1011), (2021), and (1012); all appear to be hemimorphic, and all show more or less want of symmetry in regard to the relative sizes of the faces of each form. The figures by Miigge, Jb. Min., ii. 18, accu- rately represent the general habit of the Scottish crystals, and Dana's SUPPLEMENT. 195 description of the morphology of Greenockite (Syst. Min., sixth edition, p. 69) embodies the results of Miigge's investigation of that species. Pyrrhotite (74). Like Graphite, this mineral proves to be an almost constant associate of limestone in the Highland Metamorphic Series ; it is of common occurrence also in the accompanying epidiorites. Pyrite (85). ARGYLLSHIRE. Strontian, a, ao, and botryoidal. Strachur, in Mica schist, in small quarry behind village, a. Onich, in old slate quarries, nickel replacing part of the iron, in large quantities, the crystals decomposing on exposure to the atmosphere (A. Thorns). Rammelsbergite (100). This mineral is stated, by Dr Heddle, on one of the tickets in the Scottish Mineral Collection in the Edinburgh Museum of Science and Art (602.3), to occur in connection with Niccolite and Dudgeonite at " Menimuir Burn, Cassencarrie." Bruiachite (175). Noticed by T. D. Wallace (Min. Mag., vi. 169) and described by Macadam (Min. Mag., vii. 42) from Loch Bruithaich, Inverness-shire, shown by Heddle to be identical with Fluor (Min. Mag., viii. 274). Amethyst (210). Occurs lining the vapour cavities in the upper of the two basic intrusive sheets at Hound Point, Dalmeny, Firth of Forth, and also forming small amygdules in a dyke traversing the red rocks below the new promenade west of Dunbar ; the same rock may be traced westward as far as the rifle butts on the east side of Belhaven Bay. Quartzine (210 A). A fibrous form of crystalline Si0 2 ; supposed to be the cryptocrys- talline constituent of Chalcedony, and therefore present in all Agates. Agate (210). Many new localities for Agates in Scotland have been discovered while the present book was passing through the press. Almost without exception they are from vesicles in rocks of sub-basic composition mostly from Augite Andesites. Mr E. Dykes has collected them from the 196 SUPPLEMENT. Devonian Andesites of the Ayrshire coast and from the Pentlands ; Mr Benjamin Brown from the same rocks near the foot of the lower reservoirs in the Pentlands; Mr J. Bisset from the same rocks at Connel Ferry ; Mr Kobertson and Mr Mears from Arthur's Seat ; the Editor has obtained them from Devonian Andesites, among other places, at St Abb's Head, various localities on the Scottish flank of the Cheviots ; from ? Andesitic lavas of Lower Carboniferous age at Jovis Neuk, N.E. of Aberlady Bay, etc. Veins of Chalcedony occur traversing the dolerite of Hawk Crag, Aberdour, and also that of Burntisland. Molybdite (219). Mo0 3 . " At Mount Coryby near Loch Creran in Argyllshire ; and at East Tulloch, south of Loch Tay, in Perthshire, according to Heddle " (Greg and Lettsom, Brit. Min., p. 348). Tenorite (230). In the Scottish Mineral Collection there is a specimen from Leadhills, which has been regarded as a pseudomorph of this species after Galena. Corundum (231). An account of the geognostical relations of Corundum (in Scotland and elsewhere) is given by Teall in his Presidential Address to the Geologists' Association, " The Natural History of Cordierite and its Associates" (Proc. G-eol. Assoc., xvi. 2, pp. 61-74). In this, Mr Teall describes the occurrence of Corundum in minute crystals in thermo- metamorphosed schists from the neighbourhood of the Cruachan diorite- granite. " The Corundum in this rock occurs in crystals and more or less irregular grains. The crystals are combinations of the hexagonal prism, the primitive rhombohedron, and the basal plane. They are sometimes flat and sometimes prismatic. The flat forms, in which the prism is feebly developed, are frequently stepped on the basal plane, owing to the repeated alternations of this face with the faces of a rhom- bohedron " (op. cit., p. 64). Mr Thorns sends the following note : "White Sapphire" of Tiree, or Corundum, was first mentioned by Greville, T.R.S., 1798, whose description was quoted by Jameson (vide his Scottish Isles, ii. 33), but this identification was almost at once abandoned and the true nature of the mineral was recognised at least as early as 1817 by Sowerby. Dr Heddle also refers it to Malacolite in his last Chapter, confirming Sowerby. SUPPLEMENT. 19? Haematite (232). This appears to be, in the great majority of cases, a vestigial product from one or other of the Eed Eocks usually from the New Red. It therefore occurs here and there over the greater part of Scotland which is not occupied by rocks of later date than the New Eed. The Editor has discussed this view of its geognostical relation in several papers, especially in " The Genesis of Scottish Minerals " (Proc. Roy. Phys. Soc.), and "Haematite on Arthur's Seat" (Trans. Geol. Soc. Edin., 1900). Ilmenite (233). Dr Heddle always distinguished between Iserine, which is the form occurring in connection with basic eruptive rocks (which forms much of the iron sand) and Ilmenite, which is confined to dynamo- metamorphosed rocks. This distinction appears to be a very useful one, and is thoroughly borne out by the facts. Nearly all the specimens of Ilmenite proper occur in connection with Quartz veins, and are associated with one or more members of the Chlorite Group. Spinel (234). Mr Teall's paper, above referred to, mentions the frequent occurrence of Spinel in thermo-metamorphosed rocks. Mr C. T. Clough has lately presented to the Edinburgh Museum a fine series of Spinels from the metamorphic marble of Glenelg, in which this mineral is associated with Diopside, Tremolite, Forsterite, a light mica (usually regarded as Phlogopite) Crystalline Graphite, and other minerals (see Clough and Pollard "On Spinel and Forsterite from the Glenelg Limestone," Q.J.G.S., Iv. 372), in which these occurrences are described, and from which the following analysis is taken : Analysis of Spinel from Glenelg. Dr Pollard (Q.J.G.S., Iv. p. 379). Sp. gr. Si0 2 A1 2 3 FeO MgO Total. 3-57 1-20 69-80 2'03 27*30 100'33 Minium (244). It is stated by Greg (Brit. Min., 388) to occur at Leadhills. There is a specimen so labelled in the Scottish Mineral Collection from that locality, which was regarded by Dr Heddle as belonging to this species. It resembles an impure Liinouite. 198 SUPPLEMENT. Psilomelane (269). Omission was made in the text of reference to the fine coloured figures of the Hoy Psilomelanes, which have been added to the illustra- tions. Oalcite (270). A considerable number of beautifully crystallised specimens of Calcite, embracing a great variety of combinations, is to be found in the Scottish Mineral Collection. The majority of these do not appear to have yet been published. Freehand drawings of about two hundred specimens, of which the forms have been determined while the present work was passing through the press, have been made by the Editor, and are placed next the specimens to which they refer. Hydroplumbite (269). Heddle (Min. Mag., viii. 201). In minute, crystalline scales (hex- agonal), forming thin, white, flakes with pearly lustre, soluble in nitric acid, the solution showing the presence of lead alone. B.B. yields water. Inferred (but on very insufficient grounds) to be 3PbO.H 2 0. Observed with Cerussite and Pyromorphite upon Galena. Locality doubtful, or perhaps from Cumberland or Leadhills. (Taken from Dana, 6th edition, p. 259.) Smithsonite (275). LOCALITIES: Dumfriesshire; Wanlockhead. (A. Thorns, on the authority of Dr Wilson of Wanlockhead.) Witherite (279). It may be well to note here that all attempts at finding Witherite at any Scottish locality have hitherto failed, although Barytes is one of the commonest minerals in the country. Orthoclase (313). AYRSHIRE. The feldspar obscurely crystallised in geodes in the microgranite of Ailsa Craig much resembles Murchisonite, and is, no doubt, a soda-orthoclase, as suggested by Teall. (James Currie.) Attention may also be directed here to a paper by Mr Currie " On the Feldspars of Canisp " (Trans. Geol. Soc. Edin., vii. 494) in which the SUPPLEMENT. 199 geognostic relations of this and the associated Albite are described, and with which is given a figure of crystal twined on m (110). Dr Flett, in the same journal (p. 482), has also described some in- teresting phenocrysts (or insets) of micropegmatite occurring in a mass of microgranite of Devonian age at Black Hill in the Pentland Hills. Microcline (315). (Additional notes supplied by James Currie.) Flannan Islands, nacreous, white (MacCulloch). ST KILDA. In drusy cavities in the Syenite, imperfectly crystallised and with Smoky Quartz (MacCulloch). " The Feldspar of the red granite of the Eoss of Mull is described by Haughton as Orthoclase : but as his analysis of the granite shows almost equal quantities of potash and soda, it would seem that the feldspar is a Microperthite and most probably a Microcline-Microper- thite." The waxy-lustred variety of Microcline occurs near Birse, micro- graphic and associated with Andesine, Apatite, and Sphene. Soda-Microcline (315A). Microscopic examination by Mr James Bisset and Mr Andrew Stenhouse of the large ejected fragments of feldspar included in the agglomerate and other eruptive rocks on the shore between Elie and St Monance in Fife, has shown that they consist of polysynthetic twins of a triclinic feldspar. This confirmation of a view which many persons have long held, following Dr Heddle's analysis (q.v.) t seems to justify the reference of this mineral to Socla-Microcline. Probably this mineral will eventually prove to be of much commoner occurrence in Scotland than has hitherto been supposed. Fine specimens from the localities mentioned, as well as from the east of Fife, are placed in the Scottish Mineral Collection. Dr Heddle gave considerable attention to the vitreous and lithoidal states of eruptive rocks, and collected a fine series, which he placed with the Feldspars when he was arranging the Scottish Mineral Collection. Amongst these are fine examples of Pitchstone from almost every known Scottish locality, as well as equally fine specimens of Tachylite. His examples from Loch Scridain, Mull, formed the subject of a paper read before the Glasgow Geological Society (vol. x. pp. 80-91). With these are placed examples of Petrosilex and Petuntze, from Black Hill, Pentlands. 200 SUPPLEMENT. Oligoclase (317). (Additional analyses). 1. Heddle, Min. Mag., iv. 197. 2 and 3. Haughton, Phil.

Sanday, near Saville, in a large boulder (probably a Norwegian erratic), white, penetrated by Actinolite, with Hornblende, Apatite, etc. Stack and Skerry, west of Hoy, in belts in the gneiss, with sericitic gneiss (James Currie). Leucite (321). Eegarding this mineral, it may be remarked that all the Analcimes which have yet been found in Scotland appear to be secondary products, and formed within pre-existent cavities within the rock in which they occur ; and no British example yet known affords any good reason for regarding Analcime as a replacement or pseudomorph of pre-existent Leucite. Augite (325). The bright green variety of Augite known as Omphacite occurs in a few localities in Scotland as a constituent of the Garnet-Amphibole- Pyroxene rock called Eclogite. Messrs Teall and Clough have lately described such from J mile KE. of Loch Coir' an Daimh, 2 miles N.E. of Glenelg. (See also Teall, Min. Mag., ix. p. 217.) It may be remarked here, that distinctly-terminated crystals of Scottish pyroxenes are of rare occurrence in collections. The Heddle Collection includes only three such of Diopside, none of which appear to have been yet figured. Crystals of Augite weathered out of the Arenig tuffs at Sanquhar, Dumfriesshire, have been obtained by Mr Macconochie. The combinations are the usual ones of a, 100 ; I, 010 ; m, 110; and s, 111, the latter forms nearly all shewing strongly-concave surfaces. Except in the idiomorphic Augites abundantly present in so many basic eruptive rocks, these four occurrences represent all that are in the Scottish Collection. SUPPLEMENT. 201 Most of the Diopsides occurring in Scotland are distinctly minerals of secondary origin, developed within marbles by thermo-metamorphic action. Only in very rare cases do they shew crystalline termina- tions although they are all idiomorphic in the prismatic zone. ^Egirine (326). Mr Teall has detected ^Egirine in an intrusive rock allied to Borolanite from the Coigach district of West Eoss-shire. It occurs in long prisms, idiomorphic in the prismatic zone, and is associated with Biotite, Orthoclase, Nepheline, Melanite, etc. Mr Cunningham Craig also records ^Egirine in granulitic rocks from Glen Lui, Aberdeenshire ; 65 N.W. Spodumene (327). In one of Dr Heddle's note-books is a record of the occurrence of this mineral " in an east and west quartz-porphyry dyke which cuts the north slope of the Cairnwell just above the col between it and Cairn Geodch and overlooking Loch Bhrotichan." Wollastonite (329). Amongst other localities where this mineral has been detected mention may be made of its occurrence in the Borolanite of the neigh- bourhood of Inchnadamff, where its existence was made known by Mr Teall (Trans. Eoy. Sue. Edin., xxxvii. p. 175.) It is associated with Orthoclase, Melanite, Nepheline, etc. Rhodonite (335). A mineral bearing a strong external resemblance to Ehodonite occurs in the metamorphic marble of Dalnabo, Glen Gairn, Aberdeenshire. Dr Heddle has, however, shewn that this is really the variety of Sphene known as Greenovite, see Dufrenoy, Ann. des M. 3rd, xxii. 529. Amphibole (338). Tremolite. INVERNESS-SHIRE. About a quarter of a mile above Eoy Bridge, in the bed of the river, in Muscovite schist, with Garnets, some of the crystals over five inches long. Scourvang Hill, south of Fort William, in limestone. Kirnish Burn, south of Fort William (A. Thorns). 202 SUPPLEMENT. Hornblende. INVERNESS-SHIRE. Fort Augustus railway cutting, below the Free Church, Gairlochy, in terminated crystals, m clr n. In Shingang Burn, in Hornblende schist, about two miles east of Banavie (A. Thorns). Beryl (344). Most of the Scottish Beryls in the Collection at the Natural History Museum in the Cromwell Eoad, London, as well as those in the Edin- burgh Museum of Science and Art, are quite devoid of any crystalline terminations (as they are allotriomorphic along (c) to other minerals). A very few, only two in the Edinburgh Museum (344 8-9), are termin- ated, and these are enclosed within dark Cairngorm. They shew the combination m cp and a very rough form, which appears to be r. They are stated to be from the Cairngorm Mountains. The terminations on all the others are in some cases fractures, in others they are impressed faces from minerals associated with them, especially from Quartz, while in the remainder these surfaces are due to etching by natural solvents. Sodalite (362). Mr Teall, Trans. Roy. Soc. Edin., xxxvii. pt. 1, No. 2, p. 175, records the occurrence of an alteration product after a mineral belonging to the Sodalite Group, in the rock Borolanite, from the neighbourhood of Inchnadamff, Cnoc na Sroine, Loch Borolan, and Ruighe Cnoc, Sutherland & Eoss. It is associated with Orthoclase, Nepheline, Melanite, etc. Garnet (370). Amongst the fine series of Garnets in the Scottish Mineral Collection are some remarkable crystals from Knock Hill, 4 m. N.E. of Grange Station, Banffshire; 86 N.W. On the d faces of these an oscillatory combination of d r s builds a step-like face looking somewhat like a low pyramid. Forsterite (375).

An arrowhead twin from Lairg which had the appearance of Keilhauite, proved, on analysis, to have much the com- position of Olivine (see Analysis 3, p. 51, vol. ii.). HEBRIDES. In the gabbro of the Cuillins (Zirkel). At Camus Daraich in Sleat, in microscopic crystals, o n k (Clough and Harker), at Dun vegan (MacCulloch). Olivine is found replaced by Prehnite at Dumbarton (Allport), but more usually it passes into Haematite on the one hand or Serpentine on the other. Examples of the former change occur at Duncarnock in Lanarkshire, Bowling (Allport) and Calton Hill (Tschermak). Serpentine with the form of Olivine is found at Bowling, Mugdock, Arthur's Seat, and jtfeilston (Allport). Sometimes the centre of the grains is unaltered Olivine ; sometimes it is Serpentine surrounded by Haematite. An intermediate stage in the transition to Haematite is shewn by the pseudomorph to which the name Ferrite was given by Mr Wallace Young. This occurs at Kilpatrick, at Gleniffer Braes (J. Young), and at Boyleston (H.). At the last locality it occurs in the form of Olivine with the combination a I c d e (as in fig. 4 Anal). It is remarkable that though Olivine of two quite diverse habits is found at this place, it is altered into Ferrite only when it occurs in the form mentioned. Analysis : Heddle, Min. Mag., v. 29.

" A crystal almost identical in appearance with the Uraliau phenakite, was found by Dr Heddle at Hillswickness Point, opposite the Drongs in Shetland. The crystal is embedded in mica slate, so that the faces are rough ; it may be merely beryl." Greg & Lettsom's Brit. Min., p. 473. Scapolite (387). This has been recorded by Mr Cunningham-Craig from calc-silicate hornfels from Altt an t' Sionnaich, Aberdeenshire ; 65 S.W. Mr Clough 204 SUPPLEMENT. records it from some Argyllshire localities, and from near Cnoc na h'Ula, near Laxford, and also from near Shieldaig, Gairloch. Idocrase (393). Amongst the specimens of this mineral from the metamorphic marble of Dalnabo, now in the Scottish Mineral Collection, are (393*8) shewing the combination a m hfp c ; (393*13), a m hfc ; (393*20), a m hfcp e u. Zircon (394). Amongst the Zircons in the Scottish Mineral Collection are two from " Brann a'Bharra " which occur in pegmatite, and shew the combination mxp (on 394/9) and maxp (on 394/10); (394/4) from Beinn Bhreac mpvu. Danburite (396). Dr Heddle at one time regarded the brownish-yellow serpentinous mineral occurring in the Glenelg marble as possibly pseudomorphous after this species. See also Totaigite, Chondrodite, Forsterite, etc. Topaz (397). The collection of minerals in the Edinburgh Museum of Science and Art contains a good series of crystallised specimens of Scottish Topaz, none of which appear to have been either figured or described. They have no localities attached to them ; but there is some reason to believe that they mostly came from the granite area to the north-west of . Invercauld, Aberdeenshire. The Editor has examined and drawn most of these. The combinations include the following: (O.M.C., 27) ml n dofyf$\ (397 17), modvf, with a broad surface formed by the basal cleavage plane (c); (397/14), mlofdc (I oscillates with three prism faces between I and m, which may be X T; M) ; (397/15), I \ q; mfc dou\ (397/16), mlfcftdou Op o>. A marked want of symmetry on either side of (a) and (b) charac- terises nearly all the crystals. They are all translucent and of a very pale bluish-green colour. In the General Collection in the same Museum there are other Scottish crystals of Topaz, which shew the following combinations : Iff n mfy fidoue\ iX^fdo] nmz IfXy doue(i I). SUPPLEMENT. 205 Andalusite (398). With reference to this mineral from Clashnarae, Aberdeenshire, Mr James Currie supplies the following note : " The crystals rarely, as noticed by Somerby, form a sheath to a central core of Labradorite ; frequently they pass insensibly into the associated Fibrolite. The colour is a uniform dull purplish red ; but the author observed that, when sectioned, they are seen to have a core which is deep purple, and purple spots at the four corners of the transverse section." See also Dr Heddle's Chapter viii., Trans. Roy. Soc. Edin., xxxix. 343-4 (1898). Fibrolite (399). Eegarding this mineral from Clashnarae, Mr Currie also writes : " Sometimes it occurs at this locality with a different habit, forming a sheath which envelops Labradorite, Quartz, and Andalusite alike. At other times it radiates in bundles or fibres through the Labradorite." See also op. cit., p. 348-9. Kyanite (400). The following note by Mr Currie has been abstracted from Mr Geo. Barrow's paper, on the thermometamorphism of the rocks of the Scottish Highlands. Q.J.G.S. " At various points in the belt of metamorphic rock, stretching from two miles east of Millden to Millton of Clova and Loch Brandy, the Kyanite occurs either more or less aggregated, or in single crystals scattered through the mass of the gneiss. In many cases these are completely coated with minute crystals of Ilmenite, giving the Kyanite a " black-leaded " appearance. The crystal faces are much rounded, and as a rule only m and t can be distinguished. The finest crystals occur in Glen Effock, bright blue in Quartz : other localities are Atton and Bonhard in Glen Clova; head of Water of Saughs; Loch Brandy; Loch Lee ; and Bulg." See also Dr Heddle's Chapter viii., Trans. l\oy. Soc. Edin., xxxix. 349-353. Datolite (401). The Scottish Mineral Collection includes a large number of well- crystallised specimens of Datolite, from various localities. None of these appear to have been referred to in the body of the work nor to have been figured. Most of the crystals are of small size ; they are implanted, as a rule, on c, 001, and their greatest elongation is parallel to 5, 010. The most 206 SUPPLEMENT. usual type consists of a combination of a m m *g c e . (&) is absent. Their geognostic relations are with the Zeolites, as they all occur as minerals of aqueous origin, and of later origin than that of the enclosing rock. They occur in cavities or the sides of fissures. The enclosing rock is invariably one of eruptive origin, and its composition ranges from ultra basic, as it is at Barn ton, through basic, as at Corstorphine, to subbasic, as occurs at Glen Farg. The symbols employed are the same as those used by Dana (6th edit.). BARNTON. mam* gnev U/v x ; (401/6/3) a m n xg m * e ; (401/10) a m g m * e. BISHOPTON.

(401/12) Gadolinite (404). Two specimens of a diorite-granite from Criffel, which contain much Sphene, include also some specimens of a mineral which presents a superficial resemblance to Allanite. They were doubtfully referred by Dr Heddle to Gadolinite, and, as such, are left in the Scottish Mineral Collection. Zoisite (406). Amongst the specimens of this mineral, from the metamorphic marble of Dalnabo, Glengairn, in the Scottish Collection, are several minute crystals which show distinct terminations. Some of these have been drawn. They each appear to be built up of a number of acicular crystals, elongated parallel to the c axis, which forms the base by which they are attached, and they consist of various combinations of a, 100 (oscillating with k, 310, q, 210, and n t 530) ; m, 100 (usually bright and smooth, but in some cases striated through oscillations with r, 120 t, 130, and l y 140), 6, 010 ; d, 101, o, 111 (strongly fluted through oscilla- tions with v, 121, and^?, 131) a trace of /, Oil upon one crystal; and SUPPLEMENT. 207 two as yet undetermined and undescribed faces lying between a and d. The multiple twinning, the strongly-marked oscillations of adjacent forms, and the tendency to unsymmetrical development, are marked charac- teristics of the specimens in the Scottish Collection. No trace of the I cleavage can be made out on any of the specimens. Specimen 406/23A shews maobnpu ; 406/10, a (oscillating with m, Jc, q, n), m (oscillating with /), p (oscillating with o, v), p predominating ; 406/10 a , multiple twins, a n m d o. None of these appear to have been previously either figured or described. Zoisite appears to be a not uncommon product of the excessive thermo- metamorphism of calcareous strata, and to be confined, at least in Scotland, to rocks with that history. As an additional example, may be mentioned the occurrence of a gneiss contiguous to limestone on the hill nearly two-thirds of a mile slightly south of east of Lochan Cul a' Mhoil (Ross-shire 6-inch, map 123), which is stated by Mr Teall to be formed essentially of layers of Zoisite and Microcline, mixed with other darker layers of Pyroxene, Calcite, and Sphene. [Q.J.G.S., Iv. p. 375.] See also Dr Heddle's Chapter viii., Trans. Roy. Soc. Udin., xxxix. pp. 356-7. Epidote (407). The Scottish Mineral Collection in the Edinburgh Museum of Science and Art includes an extensive series of this mineral, including several well-crystallised groups, none of which appear to have been previously figured or described. (407/25) m era I] mca/3r; mrchnlo', from a cavity in a boulder of decomposed epidiorite, found in the Asylum Grounds at Inverness ; (407/57) ma crno\ narcib', from rock near metamorphic marble, Crathie, J mile E. of Balmoral, Aberdeenshire.

Slender fascicles of minute acicular crystals, coating a vapour cavity within a thermo-metamorphosed eruptive rock of Tertiary age. 208 SUPPLEMENT. The majority of Epidotes appear to have been reconstructed from what were originally decomposition products of ferro-magnesian silicates, which were associated with carbonate of lime, and have afterwards been subjected to thermo-metamorphism. Allanite (409). The specimens of this mineral in the Scottish Mineral Collection are nearly all idiomorphic along the zone (cd), forming prisms of the combination a c r. In many cases the Allanites form nuclei around which crystalline felspar is disposed in radial groups. In one single specimen of this mineral (409/27), from the Boat of Garten, a distinct termination is seen. It consists of the combination nacrd. It has lately been figured by the Editor. Unlike Epidote, which is very generally a product of later date, the enclosing rock, Allanite appears to be always an original constituent, and one of the earlier minerals to consolidate. It seems to be chiefly confined to deep-seated rocks of eruptive origin. The other allied and essentially isomorphous mineral Zoisite, appears in Scotland to be usually a secondary product, due to the thermo-metamorphism of rocks contiguous to limestones. The presence of Allanite in a rock is often revealed by a rusty stain which surrounds the mineral. Uigite (411). Heddle, Edin. New Phil. Journal, iv. ; Min. Mag., v. 26. " In radiating sheafy clusters of plates, in nests in the amygdaloid of Uig, Skye, along with Analcime and Faroelite. H. 5'5 ; G. 2-284; lustre pearly; colour white, slightly yellowish.

Dana remarks that it is near Prehnite in structure. Chondrodite (415). Greg, Brit. Min., p. 223, states that this mineral " occurs in small crystalline masses of a brownish yellow colour in granular carbonate of lime, with magnetite and arsenical pyrites, near Loch Ness in Scotland." The author (of the present work) has in vain searched for it, and believes that the only specimen in existence that in the British Museum, South Kensington is merely yellow serpentine. Possibly SUPPLEMENT. 209 the origin of the statement is the occurrence at Millton in Glen Urquhart of the mineral to which the author (Dr Heddle) has given the name of Xantholite (see Min. Mag. 111. 59) (James Currie). Part of the minerals from G-lenelg, at one time doubtfully referred to Chondrodite, is now recognised as Forsterite (see Teall, Q.J.Gr.S., lv.). For the supposed Chondrodite of Eum see " Olivine." Calamine (423). ARGYLLSHIRE. Strontian. Botryoidal (A. Thorns). Staurolite (428). INVERNESS-SHIRE. Kirnish Burn, south of Fort William (A. Thorns). Stilbite (443). Sheaves of crystals of a bright venetian-red or almost vermilion- coloured Stilbite occur in veins and coating the joint faces of basalt lavas (and even, in some cases, of the adjoining tuffs) in the Lower Car- boniferous rocks of Pettycur and Kinghorn on the coast of Fife. The crystals resolve themselves into the usual cruciform penetration twins. Sphaerostilbite (443). (Note by Mr Currie.) The Sphcerostilbite of Beudant, described originally from the Faroes, is mere Stilbite in minute crystals, dropped upon delicate radiating tufts of Mesolite, the presence of which deter- mines the spherical form and causes the gelatin ization with acids. It occurs in Skye ; at Storr in minute spheres sprinkled over Faroelite, and at Quiraing in spheres the size of a pea with other Zeolites.

It consists of small spheres of a pale olive green colour with a dark nucleus. They have a finely radiated structure, and, at the same time, they are concentrically banded. The mineral is not unlike the impure variety of Thomsonite which has been named Chlorastrolite." Fuchsite (458). Micas containing various small percentages of Chromium are of not uncommon occurrence in the Highland Metamorphic Series, especially in the altered quartzites, according to Mr Geo. Barrow. Mr Barrow VOL. II. 210 SUPPLEMENT. remarks, however, that much of the green micaceous mineral which is commonly referred (on account of its colour) to this species is really one of the Chlorites. Lepidolite (460). Is said to have been obtained from " Argyll, in primitive limestone at a quarry on the east side of Loch Leven, opposite the inn at Ballichulish. Eeported to occur at Dalmally." Greg & Lettsom, Brit. Min., p. 225. For Fuchsite, Damourite, Margarodite, and Sericite (see Muscovite 458). Phlogopite (462a). There still appears to be some doubt whether some of the light mica, occurring in the marbles of the Highland Metamorphic Series, is really Phlogopite, as it was at one time assumed to be. Dr Heddle states with regard to the light mica of the Gleuelg marble that it is so like a Vosges mica named Phlogopite by Prof. King that it is possible it may prove to be this most highly magnesian species. (See Trans. Roy. Soc. Edin.) Ottrelite (467). In the Ann. Eep. Geol. Survey for 1895, p. 23, Mr Geo. Barrow records the occurrence of this mineral as a product of the thermo-meta- morphism of the ancient sediments of the southern border of the Scottish Highlands. It is associated with Cordierite, Andalusite, etc. Saponite (488). 5. Additional analyses by Dobbie (Min. Mag., v. 131). Si0 2 . A1 2 3 . Fe 2 3 . FeO. MnO. CaO. MgO. H 2 0. Total.

Wolfram (812). MacCulloch states in the Trans. G-eol. Soc. Lond., ii. (1814), that this mineral, which had hitherto not been recorded from Scotland, had been found in the granite veins traversing the gneiss of Eona. But in the Western Isles, published in 1819, he appears to have come to the con- clusion that the mineral in question was Magnetite a view which Dr Heddle endorsed. Easpe also appears to have made the same mistake with reference to Tiree (see Trans. Roy. Soc. Edin., xxx. pp. 452-3).

ABERDEENSHIEE. In a deep part of the Quarry of Eubislaw near Aberdeen. Imbedded along with crystals of Muscovite in an exfiltration vein. It occurred in a solid lump, and also forming a " corded structure " pervading Feldspar, identical in appearance with that noted by me in Feldspar : it thus occupied the position of the Oligoclase or Albite which usually forms that structure.

APPENDIX BY THE AUTHOR, MINERALS which have been stated to occur in Scotland, but which occurrences are either improbable or not sufficiently authenticated : MERCURY. Said to have been found in clay near Berwick ; and to the amount of several pounds in a peat bog near Loch Fyne. PLATINUM. Said to have been found on a farm near Buittle, near the mouth of the river Urr, in Kirkcudbright. Possibly Molybdenite. CHRYSOBERYL. BROOKITE. Some minute crystals upon Ilmenite and also upon Eutile from Creag na Caillich seem to be Brookite, but are too minute for determination. XANTHOSIDERITE. An ochre-coloured iron ore in fibres of two inches in length, and containing nearly 20 per cent, of water, is found, rarely, in loose pieces along the summit of Hoy Head (St John's Head, Hoy, Orkney), and may be this mineral.

Edin' OF THE UNIVERSITY OF MAP OF SCOTLAND ISLANDS 127?- 125 SOLA SGEIN Scale - 60 MUes to I Inch SYNONYMIC INDEX TO SCOTTISH MINERAL LOCALITIES. BY J. G. GOODCHILD. THE orthography adopted is that used on the maps of the Ordnance Survey : other spellings which have been used being given in quotation marks. Localities as yet unidentified are distinguished by a prefixed f. Following the name of the locality is given the parish or some other easily-identified district in which the place occurs, then the name of the county, and finally a reference to the Ordnance One-Inch Map (distinguished as O.S.) in which the place is found. The numbers following (Sp.) refer to the species of minerals known to occur at the places mentioned, and are those under which these minerals are arranged in the body of the book. They are also the same as are used by Dana (Sixth Edition), and in the Collection of Scottish Minerals in the Edin- burgh Museum of Science and Art. Mr James Currie's information, given while the body of the work was passing through the press, has been freely used in this list, and I have to thank Mr J. G. Duncan for assisting me in drawing up the lists of minerals from those in the Scottish Collection, and both Mr Currie and my colleague Mr Macconochie for valuable help in the revision of the proofs of this list.
