212 THE PHOTOGRAPHIC NEWS. [MAY 2,186 1 ounce 0 ounces. Chloride of gold . Carbonate of soda. Water 15 grains 150 „ 15 ounces. In the large hall of the “ Odeon," we had occasion to witness a festival on the 22nd of February, which, as to its importance to German art and industry, may worthily be placed side by side with the celebration which Mr. Borsig, of Berlin, gave to his workmen on the occasion of the completion of the 1000th locomotive engine. In the optical institution of Messrs. Voigtlander and Son, the 10,000th photographic instrument had been completed already towards the end of the past year, and in celebration of this event, the head of the firm, M. Voigtlander, regaled his workmen with a splendid supper, followed by a grand ball, which was kept up till a very late hour, and was in all a very happy affair. The 10,000th instru ment had been retained for the occasion, and stood finely decorated in the hall, surrounded by Austrian and Brunswick flags, transparencies, &c., headed by a portrait of M. Voigt lander. At supper, a large silver cup was presented to M. Voigtlander by the oldest workman, and an appropriate address made by M. Bossing, also one of the oldest men. After the ball, M. and Madame Voigtlander were serenaded at their residence. As we spoke of the importance of this celebration, we owe, perhaps, a proof of it, which will bo the more welcome as nearly everybody is greatly interested in photography. When Daguerre made his famous invention, he was confined to take lifeless objects, for, as is universally known, at that time only lenses with weak power of light were used; but when Voigt lander came out with his double lenses, made according to the calculations of Professor Petzval, it was possible to take por traits. The grand achievement was then universally applauded, and the inventor rewarded by a medal, struck expressly for this purpose in Paris. It is natural that owing to the great success of Voigtlander, many manufactories of such lenses were opened in all countries; but up to the present day the lenses of Voigtlander have preserved their old fame, the least proof of which is the 10,000th lens, and the fact that they are found in all the first establishments in the world.

Toniny Solution. nearly all likenesses taken by the new method nowT arises from the fact that the sitter being in a novel sil unconsciously assumes a constrained and unnatural esS of countenance, and havipg no means of correcting" is of course repeated in the picture. Hence, so fet are entirely satisfied with their photographs. The 0 ment we suggest, is designee! to obviate this de” of Messrs. Voigtlander and Son has recently been vastly enlarged, and yet it is impossible to satisfy the daily increasing demands; and they count on making 2000 lenses this year, whilst the 10,000 have been produced in twenty years, an average of 500 a year. Besides these lenses, the institution produces also a very large number of opera glasses, which they also made first with achromatic lenses. These are principally bought in England, where they are universally known by the • name “Voigtlander,” and at raceswill be found in the pos session of every gentleman. It would occupy too much space to enumerate all the different branches of the establishment, and we will only mention, that even twenty-five years ago, M. Voigtlander produced telescopes, which, according to the judgment of Gauss, Schumacher, and others, were found equal, and even in some respects superior, to the renowned Frauen- hofer telescopes. The present proprietor of the establishment, which was founded one hundred years ago by his grandfather, was always on the alert to extend the business as much as pos sible, and succeeded in doing this principally by his connections with other countries. Thus we meet here with the rare com binations of artistic efforts and commercial enterprise. We conclude this report, which we felt ourselves bound to make, with a hearty wish that we may soon bo able to congratulate M. Voigtlander on the completion of the next 10,000 lenses. • TO HOLD THE MIRROR UP TO NATUB Ms. Edward L.
