The goods enumerated in this Catalogue can be purchased from any dealer in Photographic requisites in this country, Great Britain, Australia, the West Indies, or in Canada. Photographers often send to New York under the supposition that dealers charge them too high prices. They will see by the prices quoted in this catalogue that such is not the case. On the other hand if goods are offered to them lower than these prices, there is good ground for caution in buying, because good goods cannot be supplied for less money. As the values of certain classes of goods fluctuate frequently, the prices in this Catalogue are subject to change without notification. When, our goods cannot be obtained of your dealer, send direct to us for them. Read over the Index to this Catalogue carefully before making out an order, so that nothing which you require shall be omitted. New Catalogues, Circulars, &c., will be mailed to any one whose address is handed or sent to us with the request for copies. Do not order your Cotton, Poisonous Chemicals, Liquids or Dry Plates to be forwarded by mail. All goods by mail sent at the risk of customer. The Photographic Times contains a description of new apparatus or goods worthy of notice. SCOVILL MANUFACTURING CO. 4z23 Broome St.^ New York. W. IRVING ADAMS, Agent. TBRMS.

SOOVIX.L MANXJFACTURIISrG^ CO. Proprietors and Managers. W. IRVING ADAMS, Agent. SCOVILL MANUFACTURING CO. In submitting the following Descriptive Price List of the American Optical Company's Photographic Apparatus to the notice of professional photographers, the manufacturers beg to state that every article is war- ranted, and will be found upon examination to be exactly as represented. This apparatus is manufactured in New York City under our immedi- ate personal supervision, and as we employ only highly skilled workmen, and use nothing but the choicest selected materials, we do not hesitate to assert that the products of our factory are unequalled in durability, excel- lence of workmanship, and style of finish. Their superiority is now freely conceded not onl)^ in this country, but throughout England, Germany, Aus- tralia, Mexico, the West Indies and South America. Quality being considered, our prices are moderate, as the same grade of apparatus cannot be supplied for less price. Dealers in photographic stock throughout this and foreign countries keep our apparatus on hand, but photographers failing to find it where they are accustomed to purchase may send their orders direct to the manu- facturers. To insure attention, all orders for special apparatus must be accom- panied by a remittance, covering one-third of the amount of proposed purchase. Our apparatus is packed with the utmost care by experienced and careful packers, hence we assume no responsibility for breakage or damage in transportation. SOOVILL MANUPAOTUEING 00., 423 Broome St., New York. Photographic Apparatus Manufactured by the American Optical Company J, New York. All of the Cameras described in this Catalogue are supplied at the same list price, whether they are fitted with Solid Glass Corner, Bonanza, or either of the styles of Dry Plate Holders. In ordering appai'attis^ parties should give the marginal numbers and style in full^ together with the nuinber of the page of this Catalogue on zvhich the same is described. When separate Holde7's are ordered^ please observe directions given on page 57, and save the delay occasioned by our being compelled to write for the outside dimensions or a diagram of the holder in present use. It is our boast that we are progressive, and hence our Apparatus is improved when it is found practicable to make changes that are real im- provements. This may cause slight departures from the printed description in this Catalogue, but please remember that all changes are for the better, and that we thus voluntarily add to the cost of production. We beg leave to emphasize the suggestion^ that customers ^ by giving their orders for apparatus befof^e they are actually in want^ will favor us greatly and spare themselves annoyance from delays^ which in our busiest season are sometimes unavoidable^ and at the same time we can give better satisfaction and more attention to their commands. 43 PORTRAIT CAMERAS. All Portrait Cameras are made with the V-shaped Wooden Guide, which we think is superior to the Metal Guide formerly attached to them Among the many improvements attached to the cameras described in the following list, to which the attention of operators is called, is the Double Swing-back, which may, during the earl^' stages of construction, be attached to all cam- eras, whether portrait or view. Any operator who has been annoyed by being unable to reflect the image upon the ground glass without distortion, will immediately see how completely this arrangement overcomes the difficulty. Very often it is desirable to get a little more of the lower or upper part of the figure, or of one side more than the other in the picture than can be done with the old style camera, without moving the person or the camera. This can be done quickly by means of the Double Swing-Back, which allows the operator to make any change, laterally or vertically, he desires. After the figure is properly delineated on the ground glass, the clamps at the side enable one to fasten the ground glass in whatever position it is wanted. When lenses of ver}- short focal length are used, the face is very often distorted, unless the operator tips his camera, and even then he is apt to get the face elongated or widened, unless he be very careful. The Swing-back is a time-saver, and helps the operator at once to overcome the trouble spoken of. It is desirable with ^//lenses. As it is a very impor- tant matter, we will make a little extract on this subject, from Mr. Lake Price's book, " Photographic Manipulation." See page 62. Extra Quality Portrait Cameras^ with Reversible Shields. The following Cameras are manufactured from the best mahogany, French polished, with India-rubber bellows, the V-shaped wooden guide, and, in sizes up to 8 x 10, with a patent focusing cam. Larger sizes, 8 x ic 44 and upward, are furnished with our Lever Focusing Attachment, by which the most delicate focus can be adjusted with the utmost facility and ease.

This is a Camera adapted for making two card pictures on one plate with one tube, and at the same time so arranged with holders and tablets that the regular sizes, from i-g to 1-2 size, may be made with one tube. Until this camera was made by the American Optical Company, the frater- nity had to put up with one of a very inferior grade. We have paid especial attention to quality and strength, as well as to beauty. It meets with an unexpected acceptance and demand. We call it "The Chicago Card Cam- era." The drawing above shows a rear and a front view of the camera. It will be seen that it is supplied with the Swing-back — although made with- out — with fine Focusing Screws, V-shaped Wooden Guides, Diaphragms, etc., and that no pains have been spared to make it good and exact. We recommend it to the attention of all who desire a really good camera.

The introduction of the beautiful new size of photograph, called in America the "Victoria," in Prussia the "Format," and in Austriathe "Eliza- beth," made it necessary to manufacture still another camera to accommo- date it. This we have done, making it somewhat after the model of the Imperial, only adapting it to smaller sizes. It works a 5 x 7 plate, and may be used t ) make two Victoria cards, using one tube, on a 5 x 7 plate ; four cartes-de-visite, using four 1-4 tubes, on a 5 x 7 plate ; and by revers- ing the four lenses it will make eight " bon tons," on a 5 x 7 plate. It also makes all regular sizes, from 1-6 to 5 x 7, using one tube. Four 1-4 lenses only accompany the camera when it is ordered fitted. The above illustration is a fair representation. It is a charming piece of apparatus aid works admirably. A novelty we have introduced with it is the catch which keeps the carriage movement in place when the camera is used as a multiplier. It is a great improvement on the old contrivance. The styles are : No. 21. — Victoria Card Camera, with four 1-4 tubes only $56 00 " without tubes 36 00 " 21(1. — New style, using two 1-4 size tubes only (without tubes). . 36 00 " with two 1-4 size tubes 46 00 N.B. — V'/ilh t lis latter camera, which has only two 1-4 tubes, the same work can he done as with the four-tube Victoria Camera. It is the only two- tube camera that will do this work. The front block separates according to the size required. Formerly these cameras were not made high enough for a Bonanza Holder, but now they are made so that it may be fitted with either an S. G. C. or Bonanza Holder. 48 The Imperial or Cabinet Portrait Cameras. Our Imperial Cabinet" Camera is one of the most useful and accept- able that we have ever produced, and it has probably done more than is generall}' accredited to it toward the production of the imperial or cabinet size of portraits. We have allowed no pains to be spared in our works to have it answer exactly all the requirements that could be made of it, and to make it perfect in all its parts. The above illustration shows it in all its beautiful proportions. It is provided with the India-rubber Bellows, the Double Swing-back, the Swinging Ground Glass, the Lever Focusing Adjuster, and the V-shaped Guides on the platform. The frame which carries the holder has a hori- zontal carriage movement, which, with the internal diaphragm provided, enables the operator to make with this camera of the 8 x lo size the follow- ing sizes and st34es : Two promenade or imperial cards on an 8 x lo plate, using one 4-4 tube ; any size single picture from 1-4 to 8 x 10 ; two cards on a 4f x 6^ or 5x8 plate, using a 1-2 size lens. It will be observed, then, that this camera may be used for all single portraits up to 8 x 10 size, and for two promenades or imperials on one 8 x 10 plate. A smaller diaphragm enables you to make two cards on a 5x8 plate. The same style of camera is made in 4-4 size. The 10 X 12 Imperial Camera is the same as the 8 x 10 Imperial and 4-4, only larger. All the Imperial Cameras can be arranged so as to take four cards and tw^o Victoria or card size with two 1-2 lenses (simply by reversing the front board, which requires an extra diaphragm).

The II X 14 Boston Imperial Camera is the same as an 11 x 14 Portrait Camera, with the addition of an 8 x 10 Carriage and an 8 x 10 Bonanza Holder, and is used to make two imperials on an 8 x 10 or 4-4 plate, using one 4-4 lens ; two cards on a 5 x 8 plate, using one 1-2 size lens ; two large panel pictures, 6 x 10 inches in size, can also be made, and regular work from II x 14 to 1-4 inclusive. No. 24c\ — II X 14 Boston Imperial Camera, double swing-back. . . $90 00 The Royal Camera. This Camera does precisely the same work as an Imperial Camera, and has all of the latest improvements. It has a carriage for the plate-holder, and the ground glass is where it is always read)' to be brought into use. When the operator brings the plate-holder from the dark room, he slides it into the carriage instead of placing it on the floor or some other incon- venient place while he obtains the focus. After securing the desired focus, he merely slides the ground glass to one side, in place of removing it, and simultaneously brings the plate-holder into place. 8 X 10 Royal Camera, double swing-back $57 00 10 X 12 " " *' . , 66 50 11 X 14 " " " 85 00 14 X 17 ** " " 100 00 Above the 8 x 10 size an extra ground glass is supplied for use in focusing when pictures of groups are being taken.

The gem of all Gem Cameras is the American Optical Company's 8 x lo Multiplying Camera, which is represented by the double figure above. It is not duplicated by any other manufactory in the world, neither is there any other which approaches it in design and accuracy. One view shows the rear and the other the front of the camera. Its regulation and move- ments hardly need to be described if the drawings are carefully examined. It is supplied with nine gem tubes to work by sliding movements vertically and horizontally, with assorted diaphragms, catches, scales, and so on, sim- ple in their nature, yet working like an automaton, which, combined, make one of the most perfect and desirable of cameras. It has been lately im- proved by the supplying of a register directly in front and a carriage at the back, and all are now made after that pattern ; consequently, when holders are ordered for Multiplying Cameras, it will be necessary to specify whether the camera in use has a carriage or not. No. 25. — 8 X 10. This camera will make seventy-two, thirty-six and eighteen gems on a 7 x 10 plate ; nine gems on a 5 x 7 plate ; eight 1-4 size cards on a 7 x 10 plate, using two 1-4 or 1-3 lenses ; eight cards, using one lens for copying, on a 7 x 10 plate ; four small imperials or four Victoria cards on a 7 x 10 plate, using a 4-4 lens ; two cabinets on a 7 x 10 plate, using a 4-4 lens ; regular work from 1-4 to 8 x 10 inclusive. When arranged so as to take eight cards with four lenses, it requires another diaphragm. The holders contain two sets of kits for ferrotypes and ne natives. The latter with glass corners: Unfitted (that is, without any tubes) $85 50 Fitted with nine 1-9 Darlot tubes = 109 00 " " and two 1-4 Darlot tubes 118 00 " " four 1-4 " . 128 00 Solid Glass Corner Holders only put on these Cameras. 51 VIEW CAMERAS. No pains have been spared to approximate perfection in the construc- tion of these Cameras. They are made as light and delicate as possible with due regard to strength and durability. Cone View Cameras. The figure represents our 8 x lo Single Swing-back View Camera, cone bellows partly extended. This bellows is much lighter than the ordinary style, and may be shut much more closely. Being very small on the front, still greater lightness is attained at no expense of strength.

It is the American Optical Com- pany's Cone Bellows View Camera, double swing-back, with the addition of a stereo, attachment and a 5 x 8 kit. Its capacity is 1-4, 1-2, 4-4, 5x8 and 8 X 10 pictures, reversible, with one tube, and stereos, on 5x 8 plate, with two tubes. The brass binding formerly put on these cameras has now been dis- pensed with, as it was not needed for strength ; it added greatly to the weight of the camera, and required considerable care to be kept bright. The improved Venus Camera, 8 x 10 size, weighs but eight pounds. The reduction in weight has been accomplished without sacrifice of strength or any requisite of merit. In fact, the camera is now pronounced to be perfect in all its parts and the maximum of beaut)^ This new pattern of a View Camera has no equal in beauty of design or lightness. The growing use of dry plates and the desire for rapid exposures led to its introduction, and because it adds to the grace and celerity of view taking it has become vastly popular. A novel arrangement of a detachable carriage at the back combines such a multiplicity of adjustments in itself that a dry-plate holder 7nay be reversed or be set for either an 8 x 10 upidght or horizontal pictwe — all of these movements without once changing the dry plate holder in the carriage, which maybe made to take an S. G. C. or any pattern of dry plate holder, but not a Bonanza Holder. Without Single Double No For View. Swing.

" These are the finest View Cameras ever constructed," so says every photographer who has examined any of them, and this ex- clamation is not merely a tribute to the beauty and grace of their design, for invariably the desire has at the same time been expressed to possess one of these truly novel and substantial Cameras. Wherein lies the merit and attractiveness of the devolving Back Camera, that photographers want to cast aside cameras now in use and procure"one of this new pattern } Briefly stated, it enables the view taker to secure either an upright or a horizontal picture without changing the plate holder after it has been slid into the carriage. No other camera can with such wondrous ease and celerity be changed from the vertical to the upright or vice versa, 54 The carriage is simply turned about in the circle and automatic- ally fastened. By this latter provision the carriage may be secured at either quarter of the circle. Ordinarily, the slide will be drawn out of the holder to the right ; but, in certain confined situations, the ability to withdraw the slide to the left enables the photog- rapher to obtain a view which he could not get with the usual provision in a camera. The photographer of experience is well aware of the difficulty, when taking an upright picture with a large camera, of reaching up to draw out the slide at the top, and, what is more essential, of getting out the slide without fogging the plate in the holder. Grace and strength are combined in the Revolving Back Camera, and its highly desirable features are gained without the sacrifice of steadiness or any other essential principle in a good camera. Indeed, its merit is such that outdoor photography has been advanced and made more attractive by its introduction. For a more detailed description read Photographic Times for May, 1883. PRICE LIST.

This is the lightest and most compact Wet Plate Camera ever made for plates of the size below mentioned. It combines every desirable feature in a stereo, camera, and is superior to all others yet introduced in that it has no loose piece or part of any description. It is made with vertical sliding front for adjusting foreground and sky. These cameras are the only ones made in this country which combine portability and lightness with dura- bility and perfect accuracy — qualities which every operator will appreciate, and which have heretofore been overlooked by apparatus makers. The Model Cameras now made have the ground glass frame arranged in focus for both wet and dry plate work. An illustration is not supplied, as they so nearly resemble the camera next described.

This Camera is so arranged that the center diaphragm maybe removed, the front changed and, with one tube, vertical or horizontal single views may be made with it, as well as all classes of stereoscopic views. The first illustration represents the camera as it is used for ordinary stereoscopic work. It is a perfect piece of workmanship — beautiful, strong No Bonanza Holders put on these Cameras. 50 and light — combining all the little neat parts that go to making up a fine piece of apparatus. It has rubber bellows. The platform is hinged so that it may fold up compactly ; the focusing cam enables one to focus exactly and quickly ; the swing-back, which is indispensable for landscape work, is attached ; the front raises and lowers, and the holder is made to fit on dowel pins, which arrangement is far preferable to sliding the holder. The ground glass is hinged fast. The second figure represents the camera turned over on its side for the purpose of making an upright single view with one tube. The partition or diaphragm (A) is removed, so the plate is not obstructed or divided ; C is a clasp which holds the holder in place when the exposure is being made, and at ^ is a clasp and screw which keeps the holder at a proper swing or angle when it is necessary to use the swing-back.

Camera we formerly made in that two lenses are used instead of four for making stereo, negatives. The pair of lenses are mounted on a front, with bellows attachment, so constructed that they may be shifted upward and downward for making an exposure on each half of the plate. Price, without swing. $52 00 Bierstadt's Pantoscopic Camera. This Camera is the invention of Mr. Edward Bierstadt, the first practi- cal worker of the Albertype Printing Process in America, and one of its present owners. The view taker who employs such a camera finds that grand possibilities, by its aid, become verities — pictures with perfect detail and freedom from distortion. It is a model of simplicity, and may be successfully operated by any photographer. The movement of the plate holder is produced by clockwork so perfectly adapted that the light is admitted from the lens through a nar- row, perpendicular slot in the holder, and travels transversely from one end of the plate to the other, embracing an angle of 120 degrees. By this means the lens always works from its centre only, hence the negative is as free from distortion and as well defined on the edges as in the centre. Mr. Morrison has made a special Lens for use with this Camera. Price of Camera and Lens, complete, for pictures 12 x 24 inches. . $150 00 Special sizes made to order. 57 STANDARD QUALITY OAIEMS. American Optical Company's Standard Quality Portrait Cameras, To meet the wants of a large class of customers who give preference to the cameras of our manufacture over those of all others, we have been induced to put into the market a cheaper class of cameras, not so highly finished as our extra quality goods, and without swing-back, but, at the same time, g-ood, well made, ii'ue and reliable cameras, and, without question, the best of their class in the market.

Price, $35.00. The form of construction of this new Camera is made apparent by the illustration here shown. The experienced copyist will not need any such simple directions for use as we append. DIRECTIONS FOR USE. To copy a negative in the natural size, place it in the kit on the front of Camera and button it in. Attached to the center frame of the Camera is a division upon which, on the side toward the Camera front, a Lens is mounted. Suppose this to be a quarter- plate Portrait Lens, the focal length of which we will suppose to be 4 inches — draw back the center frame and the Lens twice the focal length of the Lens (8 inches) ; slide the back frame with ground glass the same distance from the center frame. To en- large with the same Lens to eight times the size of the original, the center of the Lens must be 4^ inches from the negative, and the ground glass be 36 inches from the center of the Lens. To reduce in the same proportion, reverse and have 36 inches from the center of the Lens to the negative, and from the center of Lens to ground glass 4^ inches. These examples will furnish a key to the following table * 60 TABLE FOR ENLARGEMENTS. Copied from the ''''British Jowmal Almanac for 1882. Focus OF Lens.

The use of the table will be seen from the following illustration : — A photographer has a carte to enlarge to four times its size, and the lens he intends employing is one of six inches equivalent focus. He must, therefore, look for 4 on the upper horizontal line, and for 6 in the first vertical column, and carry his eye to where these two join, which will be at 30 — 7-^. The greater of these is the distance the sensitive plate must be from the center of the lens, and the lesser, the distance of the pict- 61 ure to be copied. To reduce a jjiciure any given number of times the same method must be followed, but in this case the greater number will represent the distance between the lens and the picture to be copied ; the latter, that between the lens and the sensitive plate. This ex[)lanation will be sufficient for every case of enlargement or reduction. If the focus of the lens be twelve inches, as this number is not in the column of focal lengths, look out for 6 in this column and multiply by 2 ; and so on with any other numbers. Copying Cameras. These Cameras are made of hard wood shellacked, not varnished* Naturally, they are without swing, but in every requisite they are com- plete ; and for this particular service, as well as others, the American Optical Company's make is sought for before all others.

Now, if the position of the film is judiciously altered by means of the Swing-back, the portions defective in focus will be seen to assume equally correct definition with the rest of the subject. "This treatment also applies to subjects in which one or the other side is nearer to the lens; by slightly altering the lateral distances, both sides come in focus. The operator can avail himself of both these movements simultaneously. "It must be observed that although the 'Swing-back' is useful in a modified degree when 'short focus' lenses are employed, much discretion must be exercised by the operator not to cause an elongated distortion of the face and person of the sitter by extreme and injudicious use of it." 62 PLATE HOLDERS, ETC. Holders for Regular Cameras^ Parts and Complete. Supplied Improved Solid Glass Double Reversible Corners. No Ground Glass, as that is furnished with all of the American Optical Co.'s Cameras. ^ In ordering Holders, parties should send their OLD Holder as sample IF POSSIBLE, to avoid mistakes; otherwise MAKER'S NAME should be given, and OUTSIDE DIMENSIONS; style of Camera for which Holders are intended; Portrait or Imperial; whether reversible or non-reversible; for PLAIN or SWING Camera (SINGLE or DOUBLE); and whether Silver-saving Bottle is wanted in the Holder. Unless a Camera is so made as to admit of it, a Saving Bottle cannot be attached to the Holder, as special depth of Holder Frame is required. ^ It is necessary, where it is desired to put a Dry Plate Holder on a Camera adapted previously for a Wet Plate Holder, to send on the Ground Glass Frame so that the focus may be adjusted for both Holders. A Wet Plate Holder In use has more or less of silver solution adhering to it, and should not be used for dry plate work, because the silver is quite liable to get on the gelatine plate and to mar the picture. ^ Where View Cameras have the Reversible Back (see page 53), it must be specified when ordering extra Holders for them. 1^ See directions on page 5 i concerningiHolders for Multiplying Cameras 1-4 Camera. 4x5 1-2 Camera. 4-4 Camera. ; 8x10 Camera. 10x12 Camera. 11x14 Camera. 14x17 Camera. 17x20 Camera. 20x24 Camera. 1-9 Inside Frames for 1-6 Inside Frames $0 58 .68 $0.58 .68 80 $0.68 .80 .90 1-4 Inside Frames for $0.80 .90 1 . 22 1-2 Inside Frames 1 i^ko . nn'flko no 4-4 Inside Frames I 22 1.35 I .22 1.58 $1.22 1.58 1.80 1.80 8 X 10 Inside Frames for $1.35 1.80 1.80 2.48 10 X 12 Inside Frames II X 14 Inside Frames $1.80 2.48 2 92 3.38 30.15 40.50 14x17 Inside Frames 17 X 20 Inside Frames 18 X 22 Inside Frames Outside Holders, no Inside Frames, for Holders complete, with Inside 3.60 4-73 5.40 7.43 8.10 10.35 9-45 12. 15 13.50 16.87 18.00 21 .60 20.25 26.55 23.40 30.60 63 Holders for Special Cameras, Parts and Complete.

Any practical photographer can, by one glance at the illustration, see where the great merit of this holder lies, how perfectly silver solution is saved, and how the trough may be fastened in the different grooves, avoid- ing the necessity of kits. This Plate Holder has now a world-wide reputation, and, because of its great merit, infringements have been attempted. Being the sole agents for the manufacture and sale of the " Bonanza Holder," we hereby notify all concerned that such holders made by other parties are infringements of said patent, and we will hold all dealers or others having infringing goods in their possession responsible in damages. In ordering holders, parties should send their old holder as sample, if possible, to avoid mistakes ; otherwise the exact dimen- sions of old holder should be given. Bonanza Holders cannot be put on any camera that will not take a silver-saving bottle in the holder.

The introduction of Dry Plates necessitated special holders, which should be more protected against the admission of light than any before constructed. Ever abreast and leading in the manufacture of the finest apparatus, the American Optical Company's factory is producing the best Dry Plate Holders that have been offered to the photographic fraternity. As nothing but seasoned material and the best workmanship is employed, there is a guarantee that the holders will not warp, crack and leak light, as some others soon do. For the guidance of those who are just taking up dry plate work, we give a brief description of the holders for this purpose now made at our factory. There is what we denominate Scovill's "Old Style" Dry Plate Holders, which are double, opening out like the covers of a book when plates are to be put in them. They are so devised that kits of lesser sizes may be car- ried in the outside frame, which permits two plates of different sizes to be used in such a holder. Scovill's " Old Style." Scovill's Patent. There is another pattern which we denominate as "Scovill's Patent Double Dry Plate Holders." They are reversible, and made to carry two plates of equal size, but no kits. Much as they are employed, we do not recommend them for use with plates above 14X 17 size, on account of the great weight of two such large lights of double thick glass, taken in con- nection with that of the holder, making it cumbrous and hard to handle. Next on the list comes the Daisy Dry Plate Holder. "This holder is a Daisy." The frequent repetition of this exclamation fixed the name by which our new holder is designated. It has the great merit of being lighter and of occupying less space than any other substantial holder ever devised. Although constructed to hold two plates, it is not thicker than a single holder. The Daisy Holder opens like a book when the dry plates are being 6*r put into or taken out of it, and is so arranged that light cannot penetrate from one side to the other. There are no projecting screws on this holder. What supplies their place is simple and more elfective. The slides have no catches, as they are unnecessary. The Daisy. Flammang's Patent. Lastly there is the Flammang Patent Dry Plate Holder," which, although single, is so arranged that kits of lesser size may be placed in it. This holder is especially adapted for use with pocket cameras, because it is so very compact, and also for use with large sized plates in the studio. Their construction is so unique that no meddling person can withdraw the front and expose a plate to white light. We trust this brief mention is sufficiently comprehensive.

In ordering holders, parties should send their old holder as sample, if possible, to avoid mistakes ; otherwise maker's name should be given and EXACT DIMENSIONS of old holder. Please specify whether kits are wanted or not, and observe directions also given at the top of page 63. Double Dry Plate Holders cannot be put on any camera having a car- riage at the back, as this frame will not permit of a reversal of the double holders. 68 B.E&ISTERIIfa SLIDES. (patented.) Extract from March ''Photographic Times J'^ To Mr. T. W. Jackson, of New- ark, N. J., an amateur of wealth and brains, credit must be given for dis- covering the application of a silicate surface to holder slides. All pho- tographers, whether professional or amateur, who have in time past puzzled their brains in the endeavor to solve such vexatious questions as these — ''Have I or have I not exposed that plate ?" If exposed, was the plate used for that prized picture?" " Shall I incur the risk of making a double exposure ?" henceforth will have themselves onl}^ to find fault with if they do not pro- cure and use in their dry-plate hold- ers registering slides. These can be written upon with slate or lead pen- cil ad libitum, and the writing erased without injury to them. Before tak- ing a picture the mottled surface of these slides is seen ; afterward they are turned, so that the blackboard surface, which was toward the sen- sitive plate, is out, and the data re- specting the exposure is pencilled thereon — a very convenient place, by the way, to consult it when develop- ing the plate. In the pleasure or excitement attendant upon picture- taking, holders have been so changed about that the note-book afforded no clue to their identity, and this has frequently been the case with dry plates in the developing-room. Happily, the remedy is now pro- vided, and by placing the control and manufacture of the patented registering slides in the hands of the Scovill Mfg. Co., there was a guarantee that both quality and quantity would be provided. Not one who has seen the registering slides but that has testified to his appreciation of them by a substan- tial order. Their introduction marks an era in the improvement of dry- plate apparatus. The material out of which these Registering Slides is made is impervious to water, and is so hard that they outlast common paper slides in the proportion of five to one. They will be supplied with new Dry Plate Cameras up to 10 x 12 size^ put in the works after this date, without addition to present price list. Additional Holder Slides of this kind supplied at the rate of \\ cents per square inch. American Optical Co.'s Patent Dry Plate Otianging Box, with Special Plate Holder, for Eield Photography. ManufactMred f}vm the Best Mahogany^ very Highly Finished, with Brass Mountings. This Dry Plate Box is acknowledged by competent judges to be the best arrangement for transferring prepared plates from the plate box to the camera in the open air. It can be adapted to rny camera, and made to contain any number of plates. The essential part of this apparatus consists in the box for holding the plates and the shield for exposing them. DIRECTIONS FOR USE. In filling the Dry Plate Changing Box with prepared plates, care must be used to have the film side toward the front. To transfer a plate from the changing box, set the shield on the dowel-pins of the sliding platform — same as an ordinary holder is set on a camera box during the exposure of the plate — push the shield and sliding platform forward until they are opposite the proper place in the box, when they become fast over the open- ing through which the plate passes. Turn the box and shield nearly upside down — say at an angle of fort3^-five degrees — and let the plate ^Wdi^ gently into the shield. Turn the cross-bar of shield around at right angles, thus securing the plate. Draw the shield and sliding platform backward to the first position, and the shield becomes disengaged from the changing box, which becomes closed by the same motion. No. I.

These Baths are already so universally known by the profession that it IS almost unnecessary to call attention to their claims for superiorit}^ over all others in use. The interior being manufactured almost entirely of glass, they will con- tain the silver solution in a perfectly pure state for any length of time, yet, on account of being cased in wood, they are the strongest bath in the mar- ket, and are the style generally used in large galleries. They are furnished with a hinged cover, so that the silver solution is protected from dust, etc., except when a plate is being dipped or removed. The front of each bath is paneled, so that when the shutter is removed the bottom maybe examined as to its freedom from sediment, a convenience which every other make of bath should possess, and of absolute importance in hot weather or tropical climates. The same sizes are also manufactured with an improved water-tight cover for field photography, and, when so arranged, can be transported filled with the solution without any danger of leaking, thus saving all the trouble of removing it from the bath when not in actual use, a very great convenience possessed by no other make.

The apparatus which is constructed at this factory is without ques- tion superior to that made anywhere else in this country, excepting only what we produce at our American Optical Factory. It is guaranteed to be substantial, well made, and in every respect finished in a workmanlike manner, mm MAMFACTEIl COMPAM, Proprietors. 73 New Haven Acme Portrait Cameras.

We have been induced by the demand for a better class of Camera Stands than have heretofore found their way into the market to introduce several new styles, combining solidity (being perfectly free from vibration) with portability and ease of adjustment, as the camera can be inclined at any angle with great celerity.

It can be set up, ready for use, quicker than any other, and with less trouble. By turning the brass buttons shown in the accompanying illustration, the legs may, in a twink- ling," be extended to the desired length, and fastened. When this tripod is placed on uneven ground, the camera it supports may be brought to the proper level by simply adjusting the length of the tripod legs. Another commendable feature of the Scovill Extension Tripod is, that it has no de- tachable parts to be misplaced or lost. Combining as it does firmness, strength, and lightness, this tripod must at once find favor with the profes- sional view taker, who very often wastes valuable time, or loses opportune moments in placing the tripod legs and changing their position to include just what is wanted in a picture, and to level the camera.

The degree of merit in an invention is most commonly in proportion to its simplicity, so that men are forced to exclaim, ^Why was not the idea conceived and wrought out before Given, on the one hand, a bit of apparatus with various intricate movements to accomplish a certain result, and, on the other hand, one that can be made to perform the same service by a single motion, and who can doubt as to which the preference will be given } The highest type of ingenuity is that which avoids a dozen mechanical complications, making a single, simple one answer the same pur- pose. When the means for the reversal of a camera are brought into notice, it is a fair test to ascertain how quickly the movement can be consummated; is the mechanism intricate or the reverse ; and, finally, does it aid in picture-taking, or, per contra, impair the worth of the production. ^^When the new reversing attachment is seen, no manual ot instruction need be consulted to ascertain how it is applied or worked. This is obvious. A cut does not convey an idea of its merit thus readily. Two brass plates, hinged at the end, are opened to form a right angle, and held rigidly in that position, or are brought to- gether and tightly clamped by a rod with a hooked end, which plays through an opening in the brass plate secured fast to the tripod top. Upon the upper plate the camera is set or unset at pleasure. Whether in the vertical or horizontal position the camera is held so firmly as to be secured against vibration. The reversal can be effected in an instant." 82 The Taylor Tripod. This tripod is of English origin. The illustration here presented makes an extended description unnecessary. Suffice it to say that this tripod is very firm when set up, and folds up compactly by simply pressing together the two upper joints of each leg, thus unsetting them from the pins on the brass top and then doubling them over on to the third joint. This move- ment is naturally reversed when placing the tripod in position to support the camera. The brass top should have the side uppermost which has the arms flush.

This Frame was made in consequence of a demand for such a pat- tern, combining lightness and strength. 1-4 size, price, each $0 50 84 Atwood's Patent Rerersible Printing Frame. This frame is square, and just as it is shown in the accompanying illus- tration. It is made with double corners, and in utility combines the action of the regular and the lengthways printing frames. It will be seen that the back also of this frame is square, with small blocks cut out to fit the corners, thus allowing the back to be placed upon the negative so that the springs and hinges will extend either lengthways or crossways of the subject. The advantage of this action will easily be perceived. Suppose the negative of a standing figure to have been placed in the Atwood Frame, and the back put in with the springs parellel to the length of the subject. Either half of the back board can be opened and thrown over on the other, in this manner allowing such an examination of the print as to show a view from the head to the foot. Again, in printing from a group negative, the back of the Atwood Frame can be placed to open crossways of the negative, thus giving an opportunity, when examining the print, of seeing all the faces. In printing a landscape where cloud negatives are used, and the back has been set in the manner just described, it is possible to contrast the sky with the other features of the view on the print. There is no reason why prints from two 5x8 negatives of different subjects may not be made at one time in an 8 x 10 Atwood Frame. Other good uses will he apparent, and we need not enumerate them. The back can be made to open two-thirds, instead of at the centre, where so desired and ordered.

The folly of paying large prices for foreign lenses is now well understood by American photographers, since those of domestic manufacture are so much lower in price and fully equal in quality. That every one interested may be fully aware of these facts, what follows is circulated. It will pay you to read the whole carefully, and in purchasing new Lenses do not forget the infor- mation here given. A NEW POKTKAIT L.ENS. The selection of a portrait lens has not inaptly been compared to the selection of a horse. An animal which would prove unexceptionable as a race-horse or hunter, might be of little value as a farmer's. hack ; while, on the other hand, the most serviceable and valuable cart-horse in the farmer's possession would be nowhere in any contested race in which rapidity or getting rapidly over the course formed the sine qua non. As in horses, so with lenses. There are instruments which are extremely rapid in action, but in which this valuable quality is secured at the expense of other equall)^ valuable properties. It is emphatically true of lenses that there is no gain without a corresponding loss. Great rapidity in a lens necessarily implies a large aperture in relation to its focus : for this is the conditi'on for rapid- ity of action. But, unfortunately, this condition is fatal to that degree of depth of definition which ought to be the concomitant of every photograph intended to lay claim to pictorial merit. Having carefully studied and analyzed the requirements of the most skill- ful photographers, the Scovill Manufacturing Company brought the full re- sources of their optical department (which is under the management of Mr. Morrison) to bear upon the production of a class of lenses which should, in the most perfect manner known to modern science, supply the want of the photographer, and hence the introduction of their now world- renowned Peerless" series of portrait combinations. In this series, it need scarcely be said, are embraced lenses of great rapidity, such as the Extra Rapid Peerless,'' which, from its large aperture and short focus, is pre-eminently the lens for securing the evanescent smile on the ever-changing face of a baby. This is the * * i ace-horse " among the optical tools required by the pho- tographer. When used without any diaphragm, it possesses an unsurpassed degree of rapidity, and hence its great value as a "baby-lens," or for any purpose in which an abnormally brief exposure is required. But, owing to the inexorable law of optics to which we have referred, depth can only be obtained by the insertion of a diaphragm, by which it is thus brought under the same conditions as other lenses. Possessing a giant's power, which can at all times be drawn upon when desired, it is not always expedient to have recourse to its full capabilities. Of late there has arisen a demand for a class of lens somewhat different from any of the recognized favorites among the portrait combinations — something that should, with full opening, possess covering power sufficient to fill an 8 X 10 plate, and defining qualities so good as to take a sharp standing figure the same size, while at the same time there should be a de- gree of penetrative power sufficient to give a depth of definition, to render it equally serviceable for groups. This desideratum is now attained, and we are happy to state that the new Full Figure" lens more than fulfills these conditions. It has been submitted to experts, who have all pronounced it an unqualified success. Its rapidity is rather greater than that of a larger lens of the same focus stopped down to equal aperture, while its range and depth of focus are remarkable. These excellent properties are obtained by the adoption of an entirely new set of curves, to which the glasses have 88 been ground ; and we think it well to state that the old lines upon which lenses have been hitherto constructed have been quite departed from, and an entirely new principle adopted in the front lens, by means of which these valuable qualities are not only secured with a degree of perfection, leaving nothing to be desired, but at a cost so low ($90) as to insure the new Full Figure " lens a place in every gallery in the country. Being absolutely rectilinear, it forms a good copying lens. From its great range, it is unsurpassed for groups ; while, when worked without any diaphragm at all, it forms a lens for portraiture second to none which re- quires an exposure not exceeding, sa)^ ten or twelve seconds in a gallery lighted in an average manner. The diameter of the lens is three inches, the equivalent focus twelve inches, and the back focus eleven and a half inches. There is an enormous demand for the new "Full Figure" lens, which, reverting to the simile with which we started, possesses in itself those properties found in the hunter, the roadster, cart-horse, and farm- yard hack, and which thus make it The Universal Lens.

(Extract from Photographic Times, Vol xiv. Page 277.) Opening the velvet-lined morocco case presented to us for our inspec- tion, we find partitioned-off space containing an ordinary 5-inch Morrison Wide-Angle Lens, on which the front and back combinations are distinctly marked with the figure 5. Beside this, in cells, are four mountings with lenses of varying focal lengths, each marked in white with a number. By unscrewing the back combination marked 5, and putting in its place the mounting marked 6, a lens of 6-inch back focus is obtained. Again, b}^ removing both these cells and replacing them with the two marked 8, a lens of 8-inch back focus is the result. By screwing in the front combin- ation marked 5 and the back combination marked 4, a lens of 4-inch back focus is obtained. Putting a front combination marked 8 and a back marked 6, a focus of 7 inches is produced. Thus the operator has a choice of five focal lengths with the one lens. Price for the whole, $80.

When the developer is prepared for use, if it is left in contact with the atmosphere it gradually decomposes and be- comes worthless. This bottle was contrived to guard against this, and has proved perfectly successful. After the developer has been used, instead of allowing it to stand in an open vessel ex- posed to the action of the air, it is poured into the bottle, care being taken to hold up the end of the rubber tube attached to the nipple at the bottom of the bottle, so that the solution cannot run out; then pour in oil of any kind suitable, such as sperm, petro- leum, etc. The oil will float upon the surface of the water and thus effectually protect it from contact with the atmosphere ; then insert the cork in its place in the neck of the bottle. When about to use the developer a second time, place the de- veloping tray containing the plate in a convenient position, take the cork out of the bottle, lower the end of the tube over the tray, and allow the proper quantity of developer to flow into the tray. When a sufficient quantity has been drawn down, replace the cork in the bottle, and keep it there until after completing the develop- ment of a plate. Then pour the remaining developer back into the bottle, for the oil will keep the air from the solution, and it may be Used over and over again. If the developer shows signs of weakening, a small quantity of new solution may be added to strengthen it. HEAD RESTS. THE " S. P. C." HEAD RESTS. These are well made of first quality cast iron.

The development of developers for dry-plate work has been very marked during the past few months. To keep pace and, in fact, to lead in the development of all that pertains to dry-plate work has been the aim of the Scovill Mfg. Co., and they now announce a new lantern for dark-room illumination, to be styled " Scovill's Non-actinic Dark-Room Lantern." In the opinion of the most eminent medical authority in England, the continued use of ruby light doubtless works very great and permanent mischief to the eye- sight. To every one this color of light has been very unpleas- ant, and the announcement that it can be safely superseded by the light penetrating orange glass properly modulated, will be hailed with satisfaction by all, both professional and amateur. Verily, the world moves, and the day of the baleful ruby light has passed away. Price, each 12 00 106 W. I. A. Ruby Light Lantern. Used when putting Dry Plates into the Holders, and also when developing them. Price, each $0 50 LIGHT IN THE DARK ROOM. CARBUTT^S MULTUM IN PARYO LANTERN. Lantern arranged for developing, and, after fixing, examining negative by opal light. The following are some of the advantages possessed by this Lantern : It is simple and easy to manage, nothing complicated, yet has three separate and distinct forms of light, and can be used for seven or more different operations in photography. It is adapted for the use of either oil or gas ; is provided with coal oil lamp, an improved patent burner and s-ilver reflector; is about nine inches square by fourteen high, with 8 x 10 light of deep ruby glass in front, and hood for protecting the eyes from the glare of the red light.

The 8 X 10 Adaptable Box has the desirable feature of being arranged so that plates of 6-| x 8^, 5x8 and 4x5 size can be washed in it in addition to the 8x10 size. 108 Price each. 5x8 Adaptable Washing Box $2.00 8 X 10 " 2.75 10 X 12 " " 3.10 It IS necessary at a certain stage of development to remove from photographic negatives all traces of Hyposulphite of Soda, and it is not generally convenient to place them where water will flow over their surface a sufficient length of time to accomplish this effectually, without injury to the sensitive film. To watch the plate is to waste time. The flow over it should be of gentle force. This can best be regulated, and a thorough cleansing from Hyposulphite of Soda of every portion of the negative be assured, by the employment of one of the continuous flow Negative Wash- ing Boxes. The Dry Plates are slid into the grooves, a guarantee that the film will not be disturbed or marred; a bit of hose is slipped over a tap, and then at the other end over the lower spout of the box, which should be used as the inlet. This receiving pipe conducts the water underneath the false bottom, which is perforated in every square inch. The result accomplished by this form of construction is to prevent the water from passing through the box with too great force. Besides acting as a check, it causes the water to be equally distributed, so that every plate and every portion of a plate is washed to the same extent. The upper spout, designed for the outlet, is made fully twice the diameter of the in- let, to guard against the possibility of overflow. SCOVILL'S WASHING BOXES- PRICE LIST.

Try one, and you will discard the knife and punch at once. For ovals and rounded corners they are worth their weight in gold. Robinson's Guides. Made of sheet iron.

C. is a sure index of superiority in texture, the paper is better wrapped than any other, and is noticeably free from spots, streaks or flaws. This paper is extremely simple in its manipulation, and there- fore very convenient for making proofs from negatives. It is also adapted for the reproduction of Mottoes^ Flans^ Drawings^ Manuscript^ Circulars^ and to show representations of Scenery,, 120 Boats, Machinery, etc., for an engraver to copy from.

How often the Amateur Photographer is heard to remark that *^as fast as he makes prints from a negative, his friends get away with them," and none are left to be treasured as evidences of his advancement in the art. In order to keep at least one picture from each negative, and to arrange the collection in the best man- ner for display and preservation, tasteful albums have been intro- duced by the Scovill Manufacturing Company. Each Album has 48 pages, 24 leaves. In them the finest card- board only is used, chemically free from anything that could in- jure a print. Muslin cloth covers with leather back and corners finish the Albums sufficiently to make them an ornament in a library or on a centre table.

The negative furnished for statue pictures is a paper negative of a pedestal, which can be adjusted to the negative of the subject that you wish to represent as a statue. To produce the statue pictures the subject should be draped in white, have the hair powdered, and be taken on a black or very dark background. After the negative is taken and varnished, the film is scraped off around the figure, cutting off the body as shown above, after which the pedestal negative is adjusted, fastened, and then printed. This negative is reversible, and can also be used for different subjects. Full directions and samples sent with each negative by mail.

It is a tin pot, as shown in cut, with a filter and funnel in the top ; rubber stopper in spout. Patent Applied For. Since the above cut was made the pot has been greatly im- proved, the whole top is slightly sunk, which makes the funnel complete. The spout is now cut level on top, allowing the whole (spout and top) to be covered with a single piece of glass, instead of the rubber stopper. Put your varnish in clean, flow your plates, and drain surplus varnish back through the funnel in the top, and you will never be troubled with specks or dirt in your varnish. Pot holds 16 ounces.

It is believed that this is the most valuable work ever offered to the working photographer. It contains 352 pages ; 7 x8f inch cover, and is l-J- inches thick. More than 100 illustrations. It give full details of all practical PROCESSES, OLD AND NEW, PUBLIC AND SECRET. Among the latter are the " Phototype," sometimes call the Artotype " process, with examples; many of the "Lightning" processes ; the " Platinotyp^ " process ; the Collodion Transfer" or " Megatype " process, and many others. 140 58 pages are devoted to Posing and Lighting ; 37 pages give instructions in Emulsion " Dry" Work ; 29 pages show how to Build and Use Skylights ; 108 pages furnish instructions for Ma- nipulating Negatives ; 37 pages are applied to Printing Formulae and Dodges; 175 pages give Notes from Authors all over the world. It is printed on fine white paper, made especially for it, and sold at the low price of $4 00, post paid. DRY PLATES. Dry Plates are sensitized negative glass (gelatine emulsion), ready for exposure, and will keep good in dry places for an in- definite time. They are put up in light-tight paper boxes, and must be opened, developed and fixed in ruby light, as the smallest ray of white light, or even candle light, will fog them. Cameras and plate 'holders must also be free from all light inside, except what comes through the lens ; even a full aperture of the lens will sometimes fog in a strong light. These plates are usually about ten times quicker working than Collodion Plates. The Instan- taneous are of course much quicker, and require more care. Any photographer can work these plates with the same instru- ments as wet plates, but require special plate holders. There is no reason why any one should fail to make good negatives from the start, if directions are followed that accompany each package of plates. They are now used by all the leading galleries, some exclusively. It may here be added — because of many inquirers — that there are no prepared Dry Ferrotype Plates ; the process is only negative. As an aid to the practical photographer, the formulas of the leading standard brands of Dry Plates are given. 141 EVERY PLATE GUARANTEED. UMPUIAMBRECUL H. Norden's Extra Rapid Gelatine Dry Plates.

Fill the developing dish with cold clear water and put the plate from the tablet in it so that the plate is entirely covered with water, then place a cover on it. For a plate 8 x 10 inches, mix in a wide mouth bottle 2 ounces of A and 2 ounces of jB. After the plate has remained one to two minutes in the water, pour off the same; then pour the developer evenly over the plate, keeping the dish in gentle motion. If air bubbles set on the plate, touch them lightly with the finger tip or with a soft hair brush. Watch the developing carefully, without exposing it more to the red light than is absolutely necessary. Do not take the plate out of the dish during the development for the purpose of looking through, but try to get accustomed to judge the intensity of the picture by the advancing red light in the dish either to the gray or black or light details. Let the plate remain in the dish until the full detail in the shadows is visible. As by the wet process, the highest lights must appear first, and afterward all detail to the darkest shadow. If the negative appears equal in all its parts at once, it is a sign of over-exposure. If the plate was under-exposed, the negative shows after two minutes' development no detail in shadows. In both cases the plates ought to be rejected, as the time and expense are more than a new exposure would cost. If not sure that the time of exposure was correct, or if a second exposure cannot take place, manage as follows : Mix for a plate 5x8 inches, J ounce No. A with l-J- ounces of water and \ ounce of No. B, commencing with this weak devel- oper. If after a minute's development the picture does not ap- pear, THE TIME OF EXPOSURE WAS TOO SHORT. In this case pour away the developer and use the Normal developer ; if the negative desires still more intensity, the time of exposure was by far too short, and it is not advisable to try a stronger developer, as it will generally cause fog. Be careful not to expose too short, as an under-exposed plate produces rough pictures. If you know the negative was under-exposed, commence with 143 mixing 1 part of No. A with 2 parts of No. and by using this solution the developer will in nearly all cases develop properly. This last solution mixed of equal parts of No. A and of No. will bring out the picture clear and brilliant. No. A produces intensity and No. ^produces the detail without giving much intensity to the lights. Should the negative not show the desired intensity, even if you add less of No. B, you can remedy the evil by mixing the Stock Solution with Bromide of Ammonium. Every one must regulate his developer by experience. After the development is completed in all its parts, take the plate out of the dish, wash carefully under frequent changes of water, until the gelatine film accepts the water entirely, and put the plate in a fixing bath of 10 per cent. Hyposulphite of Soda. Leave the plate, after all brom. silver has disappeared, a few min- utes in the natron, and rinse well with plenty of water. You can- not give too much attention to a thorough washing of the plates. To give the negative a gray color, pour immediately and re- peatedly a dissolution of one ounce of water with ten drops of diluted nitric acid over the plate after taking it from the fixing bath, wash again, and the plate can be set aside to dry exposed to daylight. The soaking of the smaller plates up to 8 x 10 before develop- ing is not absolutely necessary, and the developer may be poured directly on the dry plates. Larger plates should never be devel- oped without soaking them before, which prevents the gelatine film from turning yellow. Keep all the solutions cool during hot weather. After the plates are fixed, put them in 10 per cent. Alum solution and then wash them carefully. There is no reason for apprehension that the film may turn yellow after this process. In negatives of little intensity the yellowish color should not be removed, as the same is very essential for procuring a brilliant and powerful copy. Under a correct treatment of the developing process, the negative will always produce the required intensity. Should the negative appear too thin, it can be strengthened as follows : STRENGTHENING SOLUTION. No. 1. — A saturated solution of Bichloride of Mercury in water. No. 2. — 6 ounces of water. The Beebe Gelatine Dry Plates, manufactured by the Chicago Dry Plate and Manufacturing Company. EVERY PLATE GUARANTEED. DIRECTIONS FOR THE MANAGEMENT OF BEEBE'S GELA- TINE DRY PLATES. To successfully work these plates, follow the instructions carefully, and until you have mastered them, do not find any 144 fault with the plates or begin any innovations in method of working them. Before opening the package of plates, see that all White Light is rigidly excluded from your dark room ; but in its place you can have all the ruby light that you want, and I advise that you take two sheets of ruby paper and make an opening for them, then you can see what you and your plates are doing. Little lamps and tiny windows are a mistake — in the quality, not the quantity, of light lies the danger of fog. The edges of your negative which have not been exposed will be a sure test. They must, when cut, be like clear glass, or your light is wrong. I take it for granted that your camera and holder are in perfect condition. There must be no cracks to leak light, nor any silver on the holder to get on the plate. Now, for a trial, take one of the plates from the box, dust it, put into holder, and make an exposure ; give one second, five seconds and ten seconds on the same subject and with the same light. Returning to the dark room, where we have the following developer ready : SOLUTION No. 1. Water 1 gallon. Carbonate of potash (salts of tartar) 1 pound. Oxalic acid 1 pound. Mix in a two gallon jar, and see that the solution tests decided- ly acid. There will be a small amount of the salt remaining that cannot be dissolved, but will filter out. SOLUTION No. 2. Water 1 quart. Protosulphate of iron 12 ounces. Let iron dissolve slowly; shake bottle occasionally ; filter, and if 32 drops sulphuric acid be added to the solution, it will stay clear. Filter these solutions carefully. If the commercial oxalate of potash is preferred, use Water (hot) 5 pints. Oxalate of potash 1 pound. See that the solution is somewhat acid ; add a little oxalic acid to make it so; let cool, filter and use in place of Solution No. 1 given above. To Develop a 5 x 8 Plate, take Solution No. 1 2 ounces. Solution No. 2 1 dram. (Always pour No. 2 into No. 1.) Put the exposed plate in the developing tray, and quickly sweep the developer over ; keep moving. Keep developer on until image is a little sunken in. Experience will show how far to carry development. When plate is removed from developer, wash carefully. Fix in a solution 145 of water, one gallon; hyposulphite of soda, sixteen ounces. Wash carefully, and place in a solution of water, one gallon ; alum, one pound. Leave for about five minutes, wash for half an hour, and when plate is removed from washing tray, brush off all sediment with a soft brush dipped in water. Let negative dry without heat. Constant motion and careful washing prevent streaks. After negative is dry, proofs may be taken before it is varnished, but care should be taken to have the paper perfectly dry. The negative should be varnished with ordinary negative var- nish or with plain collodion before any considerable number oi prints are made from it, as the film is liable to become stained by the silver in the paper. NOTES. Large plates may be wetted before the application of the devel- oper, if preferred. If extra intensity is desired, add a few drops of a fifteen-grain solution of bromide of potassium to each ounce of developer before applying to the plate. To make clean work, dust off the plate before exposure, filter the solutions and avoid air bubbles on the plate. The iron should be added to the oxalate, and not vice versa. If too much iron is added, it will cause a bright yellow sandy pre- cipitate on the plate. Never add iron to developer in developing tray, always pour into a graduate. A tray should always be used for developing, and enough de- veloper to fully cover the plate. A very convenient developing tray can be made of planished copper, tin side in, but such a tray cannot be used for hypo., alum or inten sification. I^^If the plate is allowed to drain too much between any of the operations, air bubbles will form on the film, which must be removed with a soft brush upon the application of the next solu- tion, otherwise its action will be unequal. It is sometimes desirable to immerse plate in a strong solution of common alum, either before or after fixing, as it hardens the film and enables it to dry quicker and cleaner. Always examine the plate from the back on the removal from *the hypo. TO INTENSIFY. Proper timing and development will render intensification un- necessary, but when it cannot be avoided the following is to be used : STOCK SOLUTION. Bichloride of mercury. 120 grains. Water 12 ounces. WASH WELL. Wash thoroughly after fixing and before applying intensifier. Leave in mercury until desired strength is obtained, wash well and 146 ' ♦ put in a solution of ammonia, 120 drops, water, 12 ounces, until blackened. TO REDUCE. Water. 12 ounces. Cyanide of potassium h ounce. Bichloride of mercury | ounce. The plate must be thoroughly washed both before and after its application. FAILURES. A knowledge of failures is sometimes useful as an aid in avoid- ing them, hence we append some of the most common. Transparent Spots. — Dust on the plate. Air bubbles on the plate. Bubbles in developer. Pink Film. — Purple by Reflected Light. — Too much am- monia in developer. Development too prolonged. Never occurs with ferrous oxalate developer. Weak and Foggy Image. — Over-exposure. White light in dark room. Reflections in camera. Weak and Clear Shadows. — Under-development. Strong and Clear Shadows. — Under-exposure. Crystallization on Finished Negatives. — Hypo, not wash- ed out. Frilling. — Immerse the plate before or after fixing in a saturated solution of common alum. |^**Most of the failures in the use of gelatine plates are from imperfect light in the dark room, or imperfect cameras or holders^ all of which cause fog more readily on a gelatine plate than a wet plate. DEVELOPER. No. 1. — Neutral oxalate of potash ... .1 pound. Water 5 pints. Make decidedly acid with citric acid, and filter. No. 2. — Iron 1 pound. Water 2 quarts ^ Filter, and add 60 drops sulphuric acid. To Develop take No. 1. — Oxalate solution 4 ounces. No. 2. — Iron 4 drams Always Have Ready a Bottle of Water , 10 ounces. Bromide ammonium 300 grains. If more intensity is needed, add 10 drops bromide solution and continue the development. Image should show through on back of plate. An over-exposed plate needs weaker developer and more bromide solution. An under-exposed plate needs stronger developer and less bromide solution. Carry the development until image is well sunken in ; do net try to hurry. ^7 Note deduction. BRICE LIST.

Developer for Carbutt's Special Portrait and Instantaneous Gelatine Dry Plates, CAUTION. — Owing to the extreme sensitiveness of these Plates, we would caution customers to be careful of the quality of the light used. Carbutt's Multum in Parvo Lantern or Trans- lucent Ruby Paper give a safe light with oil or gas. THIS DEVELOPER will be found to allow of shorter exposure and gives finer modulation to the negative than is generally obtained with Ferrous Oxalate ; but for these Plates we prefer and recommend the following simple formula of Pyro. and Common Washing Soda ; however, Ferrous Oxalate may be used by those who prefer it. «49 No. 1.— 10 PER CENT. PYRO. SOLUTION. Pyrogallic Acid 1 ounce. Oxalic Acid 120 grains. Water 8 ounces. Dissolve the Acid, then add the Pyro. and Water to make 10 ounces fluid. No. 2.— SODA SOLUTION.

Oxalic Acid .... J ounce. Water 20 ounces. wash for a minute or two, then fix in Solution of Hyposulphite of Soda, 1 to 5 of water, then wash mos^ thoroughly. The nega- tive may again be placed in the Alum Solution in case the yellow color had not all been discharged by che first application. Over- Exposure. — If on applying the Developer the image comes too quick, at once remove Plate and wash off. To the Developer add half a dram Citrate Soda Solution, one dram more Pyro. Solution, and one ounce Water ; the development will now be slower and vigor secured as in a properly timed negative. For under-exposure add one or two drams saturated Soda Solution. For instantaneous Exposure, add one dram No. 1 to 2 ounces No. 2 Soda Solution. This Developer, while the cheapest, has given the most satisfactory results in Portraiture and Landscape, and I strongly recommend a trial of it by those using the Key- stone Plates. How to make Transparencies on Carbntt^s Keystone Plates. When to be made by contact, use artificial light, either gas or coal oil lamp, but the most efficient is the light from CARBUTT'S MULTUM IN PARVO LANTEJLN. 150 Use a deep printing frame with a piece of plate or flat glass to lay Negative on, place over the Negative a Keystone A Plate, then expose from 10 or 20 seconds or what may be considered sufficient according to the intensity of Negative being used, the time of exposure and strength of developer are the two principal factors in determining the TONE and DENSITY of the resultant transparency, a short exposure with strong developer yields vigorous transparencies with rich velvet black tone, long exposure and dilute developer gives warm brown tones, fine gradation with transparency of detail in the Shadows, suitable for Optical Lantern Slides. For transparencies for the window, a mask with a suitable central opening should be placed between the Negative and Gela- tine Dry Plate. A suitable paper is a thin enameled surface paper of a Turkey red color, this will be found to protect the margin of the plate and give a sharp clean outline to the picture.

Soda in 20 ounces of water, place in Alum Solution a few minutes, then give a thorough washing, and before putting to dry, with a swab of absorbent cotton go over the surface while holding the transparency under the tap, rinse and place to dry spontaneously, and it is then ready to bind in the metal frames sold by dealers for that purpose. N.B. — By leaving out the 200 grains Citric Acid in the above Oxalate Solution, it is then suitable for the ordinary Negative Developer. 151 t THE NEW ALKALINE DEVELOPER FOR MONROE'S PLATES. Formula. — No. 1. In 64 ozs. of water, dissolve 1 oz. Sulphite Soda, then add 20 grains Citric Acid, and lastly 1 oz. Pyrogallic Acid. This solution will keep indefinitely. N.B. — Be sure and use Sulph^V^ not Sulphate. We give preference to Power & Wightman's as being the most suitable. Use only the crystals, not granular. No. 2. Water 64 ozs.; Brom. Potass., 120 grains; Stronger Water Ammonia, l}/^ ozs. Keep well corked. In warm weather use alum bath after development, Development. — For proper exposure use equal parts of No. 1 and No. 2. For under-exposure, more of No. 2. For over-exposure, three parts No. 1 to one or two parts No. 2. The solution can be used for several successive plates, but after standing should have a slight addition of No. 2. When fixing bath becomes too red, use new solution. Caution. — Too long development makes the negative too intense and strong. Proper handling will produce the finest results ever obtained on Gelatine Dry Plates, both for richness in chemical eflfectand rapid printing qualities. This developer used on the " semper idem " plate possesses the valuable property of not discoloring the film, which, together with the quickness of its action, makes it vastly superior to oxalate. For additional instruction see the complete directions sent with each package. Note. — Unless pure chemicals are used for the above, trouble may be expected. Use only Schering's (German) Pyro. or best English makes. Do not use trays that have had Oxalate or Iron in them without first putting in a small quantity of dilute Pyro. developer and then rinsing. Do not fix plates developed with Pyro. in Hypo, bath that has been used for plates developed with Oxalate. The No. 1 solution should be only slightly colored by the Pyro. — a per- ceptible straw color. Should it be darker it is evidence of impurity some- where. Mix No. 1 in the order written. Any rust from the faucet will change the color very much. The Sulphite can be dissolved in hot water or pulverized in a mortar. Should any of our customers dislike the Sulphite formulas that we recommend, we give below another formula for Pyro. development, which works perfectly on our plates ; it also works somewhat softer than the first mentioned : Developers. — No. 1. Pyrogallic Acid, 1 oz. ; Alcohol, 8 ozs. No. 2. Bromide Potass., 120 grs.; Water, 7 ozs.; Stronger Ammonia, 1 oz. Use one dram of No. 1, one dram of No. 2, water 4 ozs. PRICES OF MONROE'S PLATES.

Use a lamp or gas jet protected by a copper flashed ruby chimney, or by a sheet of yellow and one of ruby paper, if care is taken to cut off the rays of white light from the lamp. If daylight is preferred, darken all but a pane or two of the window, which is to be covered with ruby paper. Direct sunlight through the paper should be avoided. Yellow paper alone only partially stops the actinic ray, and is therefore worthless. [Lamps and ruby paper are kept in stock and can be supplied by us on short notice, if desired,] EXPOSURE. The proper time of exposure can be ascertained by making several exposures on the same plate, say one-half, one, two and three seconds, by successive partial withdrawals ot the slide, and developing as if but one exposure had been made, always remembering that these plates are fully twenty-five times the rapidity of the average wet plate, and of a uniformity which obviates the necessity of the experiment ever being repeated. DEVELOPMENT. The very great advantage of the Pyro. development over the Oxalate is now admitted by nearly all photographers. Its rapidity and simplicity are points in its favor. The " Insoluble " plate works especially well with the Pyro., and although many developers give good results, we recommend only the following as giving the best quality, producing a rich, velvety texture, combined with great snap and clearness in the finished negative, and we decline to be responsible where any other is used: FORMULA. STOCK SOLUTION. Pyro. (English or German make) 1 ounce. Bromide Ammonium 600 grains. Water 6 ounces. Nitric Acid 20 drops. A. — Take of Stock , , , , ^ ounce. Water 10 ounces. B. — Stronger Water Ammonia 34^ ounce. Water 10 ounces. The above solutions will keep indefinitely. Equal parts of A and B are a normal developer. A little more of A will retard and give density — more of B gives addi- tional softness and hastens development. The development should be begun with a less quantity of B, which may be increased if the image comes up too slowly. To gain intensity and prevent fog and flatness where a plate has been over-exposed, add from 34 ounce of the following solution to the 153 developer. Any amount of density may be obtained by use of more or less of this solution of Bromide of Ammonium or Potassium. Bromide of Ammonium 100 grains. Water 10 ounces. See that all your chemicals are fresh and pure. It is absolutely necessary that above instructions be followed to obtain best results from our plates. FIXING BATH. A saturated solution of Hypo. PYRO. STAINS. To remove the yellow Pyro. stains from a plate, thus giving the appear- ance of a wet plate, immerse the negative in a saturated solution of alum, after fixing and washing. If reduction of intensity is desired, a very few drops of muriatic acid added to the alum will produce the result. INTENSIFICATION. Should intensity be needed, which may arise from over-exposure, the following is recommended. The operation is to be performed after fixing and washing. No. 1. — Bichloride of Mercury 60 grains. Water 6 ounces. No. 2. — Iodide Potassium 90 grains. Water 2 ounces. No. (5.— Hypo 120 grains. Water 2 ounces. Pour No. 2 into No. 1, shake and add No. 3. Place negative in dish kept for the purpose, and cover with sufficient solution ; when strong enough, wash well. Solution can be used repeatedly. Wash thoroughly after each operation. INSOLUBILITY. We have adopted the name "Insoluble" as a distinctive brand for our plates, and with our developer we guarantee them absolutely non-frilling in any climate ; we do not, however, recommend the severe and unneces- sary test of hot water. The plates can be easily made insoluble to that extent if desired, but at the expense of extreme sensitiveness and quality; it is therefore considered desirable to carry the insolubility only to a point which will make the plates non-frilling at all ordinary temperatures. RAPID DRYING. By flowing the plate with alcohol immediately after fixing, draining and hanging on tacks, it will be found to dry rapidly. Any stains on the hands produced by the use of Pyro. may be removed with a weak solution of Hydrochloric Acid. REMARKS Always dust off the plate, before exposure, with a soft Ijrush, to avoid small spots liable to appear in the finished negative. Always flood the plato at one sweep with the developer, and keep plate out of the solutions for examination as short a time as possible, as in either 154 instance air bubbles are liable to form on the film. Should such appear they must be instantly wiped away with a small brush. Keep your solution clean by filtering occasionally. FAILURES. Some of the most frequent causes of failure are as follows : Transparent spots — Dust on the plate. Air bubbles allowed to form on the plate. Bubbles in developer. Pink film {^purple by reflected light) — Too much ammonia in developer. Development too prolonged. Weak and foggy image — Over-exposure. White light in dark room. Reflection in camera. Too weak with clear shadows — Under-development Too strong with clear shadozvs — Under-exposure. Crystallization on finished negatives — Hypo, not washed out. NOTICE. Large figures will be found stamped on the bottom of each package of our plates ; they are simply for the manufacturers' convenience ; all our plates will be found uniform. A record is kept by aid of these numbers, and parties corresponding with us in regard to any particular lot of plates will kindly quote them. PRICE msT. Size.
