Mat 14, 1869.J THE PHOTOGRAPHIC NEWS. 239 expressed that the methods Mr. M’Craw had explained might be of great service in wedding the truth of photography to the beauty of miniature painting. At the close of an interesting discussion, a hearty vote of thanks was awarded to Mr. MOraw. Various donations of prints to the Society’s album were made, and examples of printing on new kinds of prepared papers were exhibited.—Scotsman. Amateur Photographic Association. A council meeting of the above Society was held Tuesday, the 7th inst., at 12, York Place, Portman Square, James GLAISHER, Esq.. F.R.S., in the chair. The minutes of the last meeting having been read and con firmed, the following members and subscribers were elected : Geo. Dundas, Esq.; B. Greene, Esq.; J. A. Prout, Esq., B.A.; G. W. 1). Green, Esq.; Capt. II. E. White; F. S. Teesdale, Esq.; A. R. Hunt, Esq.; C. Harrison, Esq.; Miss Cumby. The Secretary then laid before the Council the following prizes, amounting in value to about eighty pounds A largo silver goblet—J. W. Richardson, Esq ; a silver goblet—Lieut.

The Council expressed great satisfaction at the prizes, and on the motion of Dr. Arthur Farre it was decided that they should be kept on view throughout the following week. The Secretary reported to the meeting that he had received a seply from tho Earl of Rosse, stating that his Lord ship would “ feel much pleasure in becoming a member of the Council.” The proceedings then terminated. Ualk in the Studio. Obituary.—Another of the veterans of photography has passed away. Sir Thomas Maryon Wilson died on tho 5th instant. He was an early calotypist, and one of Dr. Diamond’s earliest pupils in the collodion process. He was one of the founders of the Photographic Society, and occupied tho posi tion of a vice-president. He continued a member until his death, and contributed to the last exhibition of tho Society. The Newcastle Carbon Printing Establishment.—It should be stated that tho Carbon Printing Establishment in Newcastle-on-Tyne, which a contributor described in our last as that of Mr. Swan, is now, in reality, that of the Autotype Company, to whom all interest in tho Patent and its working belongs. ALBUNEXO-CHLORIDE of Silver for Printing on Painter’s Canvas, etc.—A correspondent sends the follow ing as a good workable formula for this process:—“ Take 1 drachm of fresh white of egg, 1 ounce of distilled water, and GO grains of chloride of ammonium or other chlorides. Put this solution in a 2-ounce bottle, shako well, and pour out into a mortar, and get rid of air-bubbles. Tako nitrate of silver 60 grains in 1 ounce of distilled water ; when dissolved, pour this sensitive solution into tho mortar containing tho above salting solution, carefully, before it ceases to precipitate; settle; decant tho water, and leave tho albumeno-chloride of silver in tho mortar half dry or wet. Drop 2 drops of 80-grain silver solution into this, and grind with a pestle until the mass assumes the condition of cream. Apply to the surface of tho canvas by the method observed in house painting. When the whole surface is coated, cross and recross the brush streaks until an even coating is secured, when the albumeno-chloride of silver should be laid oft as smoothly as possible, and the brush-marks finally removed with a grainer’s badger or softening brush. Then dry before the fire. Print under a negative in the usual way. Wash in plain water. Tone in gold-toning, and fix in a hypo solution as usual.” Velocipedes and Photography.—The New York corre spondent of the Philadelphia Photographer, referring to the velocipede mania, says :—•' I cannot permit this letter to leave my hands without entering a protest against the now popular mania of velocipede riding, which muscular sport—one that requires more legs than brains—I regret to announce, has cap tivated one of our shining lights—no less a luminary than the veritable author of a series of serio-comic letters well known to all, a few years since, as the ‘ Adventures and Experience of Daddy Long Legs.’ Your correspondent protested when he first beheld naid gentleman astride of one of ‘ them things.’ It was iost, however, as tho said ‘ two-wheeler ’ declared it was the very thing for a photographer to get about upon; he in tended having a rack behind to carry his traps, and other fine theories which may do to dream about, but will never come into use photographically.” Reproducing Negatives by Collodio-Chloride of Silver.—Dr. Vogel says, in the Philadelphia Photographer: “ Since Obernetter introduced his collodio-chloride of silver paper, there have appeared many similar preparations, all of which, however, had the drawback that the film was apt to leave the paper, and the pictures were easily injured. A Mr. Ost, in Vienna, has resently prepared a collodio-chloride of silver with which he makes paper free from this fault, and which even permits the entire removal of the film from the paper, and its transfer to glass or porcelain. Mr. Ost has made faultless positives on glass of a size of twenty inches, and, by repeating the process, has produced new negatives of such ex cellence that they can be used as the original plates. Such a process is of the utmost value for the reproduction or multipli cation of rare negatives; as, for instance, landscapes, or the portraits of deceased persons. Tile original negative can of course be retouched, likewise the positive ; and wo will finally obtain a negative in which all the results of the different re touches are incorporated. Mr. Herzog, in Bremen, a well- known landscape photographer, reproduces all his stereos by this process, and only prints from the duplicated negative.” Preparations for the Season.—The New York corre- spondentof the Philadelphia Photographer refers to preparations amongst professional portraitists in New York for the coming season. The hint to make such preparations by renewal of specimens, &c., is one which is worth the attention of all portraitists. He says: “ The bright spring sun has had its effect upon photographers as well as upon their wives; the yearly mania of cleaning has extended its sway as far as the gallery and reception rooms of the craft, where we see new carpeting, now accessories, washed windows, and every other sign by which evidence of renewed and vigorous life tells its story.” Absorption of Light by the Air.—Professor H. Wild has continued his interesting investigations upon this subject in Germany, and the conclusion at which he has arrived is highly remarkable, the Scientific Review states. He finds that dry air is rather more transparent than damp air, though common observation of the clearness of tho atmosphere after a shower, or in dry weather without fog, would induce a contrary belief. He gives for the coefficient of dry air, quite exempt from dust in suspension, and seen through a thickness of one meter at 10° C., and 719 millimetres of pressure, a = 0-99178. In air like wise deprived ot dust, at 13° C. and 719 m.m. pressure but saturated with damp, a = 0 99030. It is therefore evident that in ordinary circumstances dust in suspension in the air diminishes its transparency in a very marked manner, and that if the atmosphere appears more transparent after a shower, it is because it is cleansed of this dust, and not, as some have thought, because it is saturated with damp. Telegraphing in Fac-simile.—A provincial contemporary says;—“ An invention, not many removes from one for tele graphing a portrait, is said by the Post to have been made by Mr. Meyer, an official engaged in tho French telegraphic service. He has discovered a plan for telegraphing fac-simile. The details are not given, but if what is published is fact, tho new system is as wonderful as the electric telegraph itself. There is no transmitter wanted ; the sender of the despatch is his own clerk. The message itself does the duty of the inter preter, and controls the electrical power so as to make it perfectly faithful. ‘That which the Meyer system gives us is not a copy more or less exact of tho message sent to us ; it is the fac-simile of our correspondent's writing, so that, thanks to this apparatus, telegraphic despatches will present, so far as regards exactitude and authenticity, all the guarantees now
