The process of manufacture Is cheap and simple. lOth. This gas may be safely and economically intro- duced into private houses. 11th. To make the Kerosene gas no alteration is re- quired in the existing gas works, except the introduction of the patent retort case, which is not expensive, and may be placed within the retort now in use. 12th. The apparatus used for purifying coal gas is ren* dered almost unnecessary, and may be much reduced in the cost. 13th. The Kerosene gas is not injured by being retained in the gasometer several weeks. 14th. The Patent Kerosene gas afibrds the cheapest, safest, and most agreeable light ever used. As but a short time has elapsed since the foregoing dis- covery was made public, only a few buildings at New York and Halifax, Nova Scotia, have been lighted with the gas, and there, men of science have examined and ipproved of it as being cheap and safe. The following notices of the Kerosene gas have appeared in the public journals of those places : From the New-York Courier & Inquirer, Feb. 1, 1860. •' Dr. Gesner has made an improvement in the construction of retorts for the production of gas, which he has patented, and which is very simple, effective, and economical. The substance used out of which he generates gas, is the bitumen found so abundantly in Trinidad, and other West India Islands. In the experiment witnessed by us, on« pound of bitumen generated six entire feet of gas, which, without being purified, burnt with a more clear and brilliant light, and with a less offenoive smell, than any gas yet furnished us by our Gas Companies. The Doctor states that he can make the gas on a large scale, at a cost of not more than fifty cents per thousand feet, which our readers will recollect, is the cost of making it at Southport and other English towns. If this be the case, and from what we saw we cannot doubt it, gas geneiated out of this substance, by his method, can bw furnished to the OiMusumers at not to exceed one dollar and a half per thousand cubic feet, and leave besides a large profit to the manufacturer. His apparatus is admirably adapted to the lighting of public houses, theatres, &o., and where the gas fixtures are owned by the occupant of the building, it can be substituted, as a generator, at very trifling expense.

BmI emplojed Dr. Gesner, a Professor of Chemistry and Oeology, whese name has become familiar to men of science in this country In conducting his experiments, the Professor, it appears, soon ob- ■eryed, that by dry-distillation, bitumen or asphaltura, like coal, or rosin, wajs capable of yielding large quantities of oarburetted and bi- carbutted hydrogen gases, now universally employed for the supply of light. But from its peculiar nature, there was a difficulty in applying this material to that purpose by any known process of manufacture. Dr Uesner, however, has succeeded in the invention of a retort which over- comes every obstacle, and renders the mode of making illuminating gas from asphaltum, extremely easy and simple. The cheapness of this article, its abundance, and the greatquantity of gas it affords, render it a rival to coal, rosin, and every other hydro-carbon heretofore emnloy. ed to supply light. *^ ' From the Now- York Evening Post, Feb. 1, 1850. OKflwcR's Illuminatinq Gas.— a new illuminating gas, and a pe cuhar retort necessary to its production, have been discovered and patented by Dr. Gesner, a distinguished chemist, of Halifax, now in the employ of the British Government. The gas is made from bitumen, sometimes called asphaltum, or mineral pitch, which Dr. Gesner says exists in inexhaustible quantities m Trinidad and other West India islands, and probably in the southern states of the Union. This mate- rial, it IS said, can be supplied at a much cheaper rate than coal, oil, or rosin, now used to produce gas light, and it affords more than double the quantity of illuminating gas than the coal employed for that pur- pose. The gas is also said to be more pure and dense than that obtained from coal, and the light superior. By the introduction of the discover- er 8 patent retort into common gas works, it is calculated that the cost of manufacture may be reduced two-thirds. The manner of burning 18 that practised universally. The simplicity of the ^apparatus and mode of manufacture, are such that this gas may be successfully made m public and private buildings. Every house may have its retort and gasometer, and the gas may be made by the fire of the kitchen range Bitumen has not heretofore been applied to any useful purpose, to any We saw some experiments made with this gas last evening at the residence of Dr. Gesner, No..93 Liberty street, where he has erected a temporary apparatus for the purpose of exhibiting his discovery to any body that may feel the least interest in th'e matter. About one pound of rude bitumen was enclosed in a retort in a common stove, from which a pipe led into a small tin reservoir where the gas was condensed, and afterwards passed into another tin vessel that served for a gasom- eter. In a few minutes the heat of the stove generated about six cubic feet of gas, which, without purification or cleansing in any manner, supplied two large burners with brilliant and unflickering light for two hours. The flame was perfectly clear and steady, and the whole appa- ratus and process of an extreme simplicity. Dr. Gesner intimates that one hundred cubic feet of this gas will cost about five cents. Gas is now sold at the rate of forty cents per one hundred cubic feet.

From the Ilulifax Nuva Scofian of Marrk 20t/<, 1850. Dr. Qesivcr'h DiscovRRir. — We are glad to learn that th« new d«- •eription of as, produced from Aaphaltum, is winning its way into fftTOur with oar citizens. This material is to be found in abundanot all oTer America, and it is said immense quantities can be procured in this Prorince. Dr. Qesner is kept busily^ employed explaining the na- ture of his discovery, and exhibiting the light to the curious in such matters. For a trifling sum, say twenty-five or thirty dollars, the whole apparatus, including retort, gasometer, &o,, may beset up in a fmblic building, and the cost of lighting the whole would not exceed a ^w pence per night. To une the Doctor's words— there is no science about it : the hall stove will manufacture the gas, and the girl that ■weeps the house may keep it in order. The exhibitions, thus far, have been in the highest degree satisfactory ; the light being remark- ably brilliant, even without the usual purifying process of the Oas- house. The light of one burner, of the ordinary size, has been ascer- tained to be by actual experiment, equal to six tallow candles. There is also another striking peculiarity in the new gas, it being of a green color which is well known to be Trateful to the eye. This property was not observed by Dr. Qesner ntil pointed out by the New York Professers. It is gratifying to le .'n that this gas is likely to get into extensive use at New York and Oiiier American cities. Dr. Qesner's son is now fitting up in the former jity, to burn the article, and to use the Aaphaltum. We also learn that it is in conteuiplation to light the Halifax Hotel by the same means. And if it be true that the article can be produced at the rate of three ahillinf'a per M. feet it cannot fail to benefit consumers of gas generally. It is even asserted by many that already has the city felt the influence of competition, in being supplied with gas of a better quality. From tlui Halifax British Colonist ofFeb'ry Q6th, 18.50. Gesner's Patent KEROSjay^ Q as. — Dr. Qesner has obtained a patent for his discovery TlrtKe Umted States, and as we understand, is now proceeding with the British Provinces and England. It is only a few aays since this new gas light was first publicly exhibited in New York, where the leading Journals and men of science have pronounced high commendations in its favour. It is stated to be admirably adapted to the illumination of single buildings, on account of its cheapness and the simplicity of the mode of manufacture. One of the New York editors states " that it requires no more skill than to boil a teakettle." The Doctor has proposed that in winter the gas shall be made in the furnace used to supply hot air where hot air is employed. In other oases the heat necessary to produce the gas may be distributed through houses by the stove pipes in common use. — The gas itself may be made in the kitchen. Light and heat are produced by the same process of manufacture. If these are not the true applications of science we are mistaken. Dr. Qesner has already ordered a retort and gasometer to be made in this city. The public may therefore expect to be further enlightened jon. the subject soon. At this we rejoice, for we believe that the time is an hand when we shall have cheaper gas and more light. Indeed the street lights seem to burn with greater brilliancy already. From the Halifax Sun of March the I8tk 1850. Dr. Qesner's discovery, if practically applied in Halifax, will be very likely to throw the present Gas Manufacturers far in the shade. The wm PATENT KBROHBNB OAS. 7 present ratea for Qm, are ruinous to consumors— especially to thost who use many burners. The man who will giTe us a cheaper light. w« •hall hail at a public benefactor. The light has been tested by prl?at« exhibition— and approved of. Its cheapness is manifest beyondf dispatc, hj the cost of production. Is there public spirit euough in the oomma- mtv to give it a public trial .' It is folly to tallt of a thing as useful and cheap, if we cannot avail oursolres of it. If, howerer, it be within cheap, our reach, let us grasp it. From the Acadian Recorder (Halifaxj of Feb' if IQth, 1850. Gcstter's Patbnt Kerosene (iAs.—In our last we made an ab- stract from the New York Journal of Commerce, in reference to Dr Oesner's discovery of a new illuminating gas, of which the leadine Journals of the Empire City, spealc in terms of the highest commenda- tion. As our space would not permit us to complete the article in question, we now give in another column, the substance of a communi- cation made by Dr. Gesner, to the Academy of Natural Sciences, of Philadelphm, of which he is an honorary member and which yery olearly.indicates the value of the discovery of our countryman, who is now about to be amply rewarded for many years of hard toil in the field of science. Assuming to be correct, the opinion which has been expressed by gentlemen of distinction in the rank- of science in the United States, lector Gesner'B scheme of generating artificial light possesses such ad- yantages as must bring it into general use. We are not apt to decide upon the merits of Inventions before trial, but we can readily belieye that better gas may be drawn, at less expense, from bitumen than coal Some attempts to cheapen the price of light ought to be made immedi- ately in this city. Although our G as Company have realized handsome dividends from their speculation for some time past, they charge con- sumers now as high as seven years ago. Neither is this the only com- Slamt that consumers make, for it is generally alleged that the gas oes not aflford so bright a light as formerly, but it burns faster, or the meter indicates a larger consumption of late than in corresponding quar- ters of previous years. The sole reason why an opposition company is delayed is, we believe, the hardness of the times. From the Halifax Hun of March 13th, 1850 MoEE Light.— The vast superiority of the newly discovered Kero- scene Gas, patented by Dr. Gesner, is unquestionable. It has been by experiments, proved to be infinitely preferable to Coal Gas, in all the material points of cheapness, purity, and safety. Competent Judges in the community have tested it upon those points, and have expressed their entire satisfaction. We trust that a movement well be at once made towards bringing this valuable article into common use amonirst us. The City might be lighted with the gas at least twenty -five per cent cheaper to the public. Come you old fellows at the South End, pile on your coals and dawn on our darkness, or we fear it is all over with your monopoly. From the Halifax Guardian. The New Light feom Bitumen.— An opportunity has been af- forded our citizens during the past week to examine the process of manufacture, the quality, &c. , of the Kerosene Gas Light lately patent- ed in this Province and elsewhere by Dr. Gesner. An apartment has t %- I 8 PATBNT KEROSENE GAS. been fitted up for the occasion at Mrs. Loveland's building, corner of HoUis and Sackville streets, which has been nightly thronged \sii\i en- quiring yisitors to whom the Doctor amply oxplainod the various par- ticulars incidental to the new product. The fullest satisfaction appears to have been giren. and the highest anticipation of the beholders as re- gards the brilliancy and beauty of the light seems to have been reali- zed. We understand that a Bill is now before the Legislature for the incorporation of a Kerosene Gas Company, with a view to bring the new article into use in the neighbouring town of Dartmouth as well as in this city. It can be supplied to consumers, we are assured, at a price oonsideiably below that of the ordinary coal gap. If all that we hear on the subject be true, its introduction will be hailed as a boon by our citizens of all classes. The following is the substance of a letter addressed to the Academy of Natural Sciences. Philadelphia. " It is remarkable, that so rich a hydro-carbon as asphaltum, should have been so long overlooked, in reference to its capabilities for af- fording light. It had been tried for fuel, pavements, and for other purposes, both in Europe and the United States, but without success, For what purpose nature had formed such vast qua,ntitie3 of bituminous matter, which still continue to flow from the earth, was a problem not readily solved, until this discovery, which brings it into operation /or illuminating purposes, to which it is admirably adapted. •'In the analysis given by the chemists of Europe, of the bitumen of Trinidad, there is a great diversity. Some have stated that it contains 30 and even 30 per cent, of silex, when in fact it seldom contains 10 per cent of silica. The specimens submitted to their investigations must have been taken from the beach forming the great pitch lagoon of the Island, where the sand of the shore is frequently mixed with the bitumen. Comparative Analysis of Coal and Bitumen. Volaiile Matter. Coke, or Carbon. Bitumen of Trinidad 65,5 36,67 Barbados 61,60 36,90 Cuba. 63,00 34,97 Yucatan 62,60 35,20 New Brunswick 64,40 35,10 Nova Scotia 63,00 39,00 Coal, best Cannel 44,00 52,60 Liverpool 40,48 54,90 " In consequence of the sulphur contained in coal, the bulk of its gases is increased,— sulphuretted hydrogen and sulphurous acid are produced. These compounus of sulphur are injurious to the illumina- ting powers of the gas, and increase its oflFensiveness. Coal also con- tains nitrogen, which ?;oes to the production of aramonii.eal liquor in the gas works. Now the bitumen seldom contains sulphur or nitrogen, and therefore its gas is free from sulphuretted hydrogen, sulphurous acid, cyanogen, sulpho-cyanogen and ammonia.

Dear Sir, — The result of our experiments with your patent material for making gas, is as follows: We charged the retort with just six lbs. of bitumen, and m one hour had extracted all the gas. Upon measuring our gas-holders we found that we had obtained a fraction over thirty-five cubic feet. The amount of coke obtained was two lbs. five oz. The gas was very dense, and with a bat-wing burner consuming two and one-tenth cubic feet per hour, we obtained a light equal to 25 candles. We found also that no purification was required. No sulphur or other deleterious product could be detected. The coke obtained is of a superior quality, being nearly pure carbon. A small quantity, of naptha was deposited in the hydraulic main, but no tarry matter could be found in the pipes or burners. The apparatus is simple and easily managed. It possesses an advantage over all other apparatus, which we have seen, in regard to simplicity, neatness and absence of smell. We think it peculiarly adapted to hotels, hos- pitals, manufactories, and other public and private buildings. (Signed,) Yourob'tserv'ts, WALWORTH, NASON & GUILD, No. 79 John-st., New- York. Db. Grsner's New Gas— We have already noticed Dr. Gesner's dis- covery of a new illuminating gas, and witnessed its softness and beauly, as well as the cheap and simple process by which it is manufactured. The Lity of Washington has been lighted with it, and at that place the exper- iment has been tried upon a large scale, and in the presence of men of 4i 14 PATENT KEROSENE OA8. r Erofound science. The result has been that the Washington Gas Company •▼e purchased the patent right for that city, and arrangements are in progress for the general employment of this new light. The gas is obtained altogether from bitumen, or asphaltum, which has already begun to supply ui article of commerce.— A*. Y. Spirit of the Times. THE PATEiNT KEROSENE GAS. The most beautiful new discovery that we are acquainted with, ai pres ent to produce light, is the Hydro-Carbon Asphalt, patented by Dr. Gesner' It contains no sulphur, and requires no purification. We have seen the gas made from it, and soft beautiiul gas it is. The asphalt, as analyzed by Drs. Jackson and Chilton, contains about 50 per cent, of volatile matter and 50 of pure carbon. It is an excellent discovery, one which — without any secret chaiLbers — has been exhibited to a number of scientific gentle- men who could appreciate its importance. W^ith six pounds of this nydro- carbon, 35 cubic feet of gas was obtained, which was very dense — one burnei- being equal t3 25 candles — consuming 2-10 cubic feet per hour. The apparatus to maxe it is so cheap and simple, that any person can buy and manage it for private families. It is a most admirable invention — Scientific American. From the Halifax British Colonist of Oct. 24th 1850. Kerosene Gas. — Pasfing along Mollis street last evening, we were attracted, together with a crowd of our citiaens, by the unusual bril- liancy of the gas light in the Stores of Messrs. Morton and Gossip, which, upon enquiry, we learned was produced from Asphaltum, the discovery of Dr. Gesner. A gasometer and other apparatus had been arranged in some building contiguous. This light, when compared with that produced from coal, presents a striking contrast — the gas burning in the windows of the surrounding stores appearing beside the new article as the flame of a candle. It is calculated that its cost is not more than one half the price of coal gas. We understand that the steamboat company intend using it for the purpose of lighting their property on the Dartmouth side. From the Morning Chronicle of Oct. 2ith 1850. The Kerosene Gas has been introduced into Morton's block of buildings; and the Earl of Dundonald inspected the premises last even- ing. A great number of i^ersons were attracted by the brilliant light exnibitf d on Wednesday night, and it seems to be the general opinion that Di . Gesner's Patent is a great fact. From the Church Times of Oct. 25th 1830. Kerosene Gas. — The superioritj of Asphaltum over coal, for the production of Gas for light, has we think, been sufficiently tested dur- ing the past week, so that not a doubt can longer exist on the subject. Whilethe experiment was conducted at a distance, and only its results communicated, there was always reason to question the statements re- Bpecting it. If this be an age when people are astonished at nothing that occurs, it is still most especially an age of humbug, and the more marked may be the public utility that is likely to follow the success of an undertaking — the greater the magnitude of the results expected to be attained — the more room is there for doubting its completion^ People are little inclined to take things for granted that may not ap* 'W'-i d.'^. rATENT KEROSENE GAS. 10 I Company ents are in is obtained I to lupply h, ai pres >r.

But seeing is be- lieTing, and the people of Halifax have had full opportunity of seeing that the Gas evolved from Asphaltum, by Dr. Gesner, burns with a brilliancy equal to any other. The shops of Mr. Morton, Druggist, and Mr. Gossip, Bookseller, were lit with the new gas on Wednesday even- ing, when (and on every evening since,) the beautiful light was the object of general admiration. It also engaged the attention of the Admi- ral, the Earl of Dundonald, who we dare say, experiences much satisfac- tion at the countenance he has afforded to the enterprise. Many may ask— What is the good of this .' We will tell them. The Gas Company charge IBs. per thousand cubic feet for the article they supply— the Kerosene Gas, we are authorised to state, can be furnished at least one fourth less. This is a public benefit, and can be understood by all. It will be felt as such by every city of the civlized world which has •dopted the modern improvement of lighting its treetsand houses. From the NovascoHaii. THE KEROSENE GAS. AH doubts as to the success of Dr. Gesner's discovery of a cheap apu brilliant light from Asphaltum, are dispelled by the reiterated notices of the press in the United States. The Scientific American, the .Veto Y»rk Albion, and a host of other respectable journals have borne testi- aaony to the value of the discovery, and the success of the Patentee. We are glad to learn that Dr. Gesner has disposed of the Patent, for the City of W«^8hington, for a remunerating sum— we are not authorised to state the ^mount— to parties in that City. He now purposes, we be- lieve, fitting up several buildings in Halifax ; and we trust the Gas Company of this city will deal with the Doctor in the most liberal spirit. If his discovery will reduce the price to the consumer— why, in the name of common sense, let us have the benefit of it. We clip the fol- lowing notice from a Washington paper : Our City Gas Lioht.— Observing the beauty of the gas light las evening, we were led to inquire into the cause, and have been informed that the light is that discovered by Dr. Gesner who has obtained a pa- tent for it in this country. It is made from bitumen, or asphaltum, of which abundant supplies may be obtained at a cheap rate, and from the quantity and quality of the gas it yields, it will reduce the cost of illu- mination fifty per cent. The Scientific American, which is good autho- rity in such cases, says : " it is an admir able invention." There is no humbug about it. Gesner's New Gas Light.— Quite a crowd was collected Jn Gran- ville Street on Wednesday evening, attracted by the unusual brilliancy of the gas light in the range of buildings extending from the corner oc- cupied by the Messrs. iVJorton as a Medicine Ware-house, to the Nova Scotia Book Store of Mr. Gossip. It was understood that the Kero- sene Gas of Dr. Gesner had been introduced, and thus for the first time in Halifax applied in a manner to afford an exhibition of its practical utility. If the interest already evinced in its success by those who have examined the new light and satisfied themselves of its quality may be considered a criterion by which to judge of it, the Kerosene Gas Light is destined to eclipse all the lesser lights of lamp and candle, if it do not go far to place an extinguisher on the ligHit produced by ordi- nary coal gas. Our present Gas Company should see to it or the bril- 16 PATENT KEROSENE GAS. * IM I lianoyof the Gesner Light may turn the eyes of their customers to tho preaent improTement, and their thoughts to the fact that a consider- able saving is promised to result from the introduction of this new article.

By information received from the New Brunswick papers, and from private letters, we learn that the mineral resources of the sister Pro- vince are at last beginning to be developed. During the past six months more than twenty mining leases have been granted by the Government, in the Counties of Albert and Westmoreland. Upwards of two thou- sand chaldrons of Bitumen, or Mineral Pitch, have already been raised • at Hillsborough, and will soon be ready for shipment to the United States, to be employed in the manufacture of gas. Beds of excellent coal from two to six feet in thickness, have been pierced at Meranguin, *nd a party of English miners are engaged to commence the working, A Mr. Steadman has also opened a vein of coal in the neighbourhood of Shediac, and is now exploring an asphaltum mine nearthe Petticodiao River. Surveys we understand are made with great energy, and there is much competition among the purchasers of mining leases. It is stated that 100,000 tons of asphaltum might be shipped next season from one mine. At present the completion of a railway, three miles in length, is required to aid its transport to the river. The Black Lead Mine of St. John, has been well penetrated, and it is understood that the proprietors have made a profitable investment. The iron works of Carlton county, which were unfortunately consumed by fire last sea- son, have been rebuilt, and have commenced the manufacture of iron from the ore of Woodstock. These facts are encouraging to the inhabi- tants of New Brunswick, and fully confirm tho predictions formerly made by Dr. Gesner in his geological reports published about ten years since. But in an equal degree they disprove the statements of Dr. Robb, and conflict with the opinions put forth by him in Professor Johnston's recent agricultural report. The mineral resources of this fine Province are evidently underrated. The opening of the above mines has aroused a new energy, and will no doubt contribute largely to the prosperity of that Province, whore all the mines and minerals are under the control of the Legislature, and open to the competition of its inhabitants. From t/ie Scientific American of Oct, 12lh, 1850. Asphaltum Mining in New Brunswick —We learn from a gentleman who has just completed a tour through the British Provinces, that extensive and very valuable mines of bitumen have been opened in the county of Albert, New Brunswick. The principal operations, at present are upon an out-cropping, from ten to fourteen feet in thickness, situated about four miles from the wharves of the Petticodiac River, near its mouth. The de- posite has been traced along the surface several miles, and the bituminous mineral appears at numerous points along aline of thickly wooded country sixty miles in length, and perhaps ten in breadth. A number of mining leases have been granted by the governn.ent The opening of roads and the projection of a railroad are on the advance, and a general spirit of enterprise and competition by the inhabitants and persons from the United States, ia exerting itself throughout that region. On the eastern side of the river, and above Belleveau village, settled by Acadian French, the a9« phaltum, or mineral pitch, occurs in a soft state, and resembles wax. ra to tho !onsider« this new md from ter Pro- c months irnment, TO thou- m raised e United excellent ranguin, vrorking. irhood of tticodiao ^nd there es.
