The Daguerreotype.—We have examined some specimens of the Daguerreotype, executed in this city by Mr. James Green, Philosophical Instrument Maker, No. 1 S. Liberty street.  The pictures represent each a single object—the most distinct is that of a large house upon the corner of Baltimore and Liberty streets taken from the window of Mr. Green’s establishment upon a copper plate of some four inches by three.  The outline of the image are perfect, and the letters of the sign attached to the building are tolerably distinct—particularly the name of Chas. H. Carroll on the upper part of the house which is occupier by Messrs. Carroll & Tinges.

Mr. Green was assisted in his experiments by Mr. Thos. Phillips.  The details and mode of preparation were mostly of his own device in those particulars wherein the French accounts of the process were not minute.  The light was received upon a prepared surface of muriate of silver precipitated upon a brass plate—not upon a silver plated surface as was the case in some of the French experiments.  The impression is made permanent by a coating of varnish which protects the delicate tracery from the action of the atmosphere, and fixes the image in all its original distinctness.

Many improvements have been already made in this beautiful art, and now that the attention of ingenious persons is fairly turned towards it, we may with reason expect still farther progress in the way of facilitating the operation, and in bringing the invention fully into practical use.  Mr. Green has every reason to be encouraged in his efforts towards this end, and we anticipate highly successful results from his well known ingenuity and industry.  The specimens of his which we have seen are quite equal in distinctness and fidelity to any which have been executed in this country, if we may take those lately exhibited in New York and Philadelphia as the standards of attainment elsewhere.

Painting With A Sunbeam.  Mr. James Green, Philosophical and Mathematical Instrument maker, Liberty street, has succeeded in obtaining by the process of the Daguerreotype, a most accurate and well defined view of Liberty street from the intersection of Baltimore street up to Saratoga.  We consider it one of the finest specimens of this beautiful art that has yet fallen under our notice.  The impression is clear and distinct, bearing the faithful image of every object contained in the view, from the Liberty Fire Engine house in the foreground, to the dwelling of the Rev. Dr. Wyatt, and the dome and spires of the cathedral in the distance.  Mr. G.’s preserving efforts have reaped an abundant reward in the success of this attempt.  The difference is very striking between this finished specimen and some of the earlier pieces which we saw in his possession during the course of his first experiments.
