IMPROVEMENTS IN THE DAGUERREOTYPE.Numerous improvements have been lately made in the beautiful art of photogeny. The baron Seguier has exhibited an instrument constructed by himself, with many ingenious modifications, having for their objects a diminution in size and weight, and a simplification, in other respects, of the entire apparatus. Several of the conditions which have been announced as required for the success of the process, may be dispensed with. It is probably, now, that the operations of the art may be rendered practicable in the open countryeven those nice and delicate ones which, at present, seem to demand protection against too strong a light. An objective glass has been constructed by M. Cauche, with the view of redressing the image obtained in the Daguerreotype; this image is now presented reversed, a circumstance which has the bad effect of destroying all vraisemblance. The Abbé Mognat has been endeavoring, in conjunction with M. Soleil, (a name of quite á propos,) to introduce the light of oxy-hydrogen gas as the principle of illumination to the objects intended to be represented. M. Bayard is said to have fully succeeded in taking impressions on paper. Mr. Fox Talbot, in England, has also done this.
IMPROVEMENTS IN THE DAGUERREOTYPE.Mr. A. S. Wolcott, of New York, has nearly revolutionized the whole process of Daguerre and brought the photogenic art to high perfection. The inventor, it is well know, could not succeed in taking likenesses from the life, and, in fact, but few objects were perfectly represented by him, unless positively white, and in broad daylight. By means of a concave mirror, in place of the ordinary lens, Mr. W. has succeeded in taking miniatures from the living subject, with absolute exactness, and in a very short space of time.
