Our Daguerreotypes.

We are assured by one in whom we have all confidence, and withal! capable of judging, that there is now in progress a machine for cleaning and buffing plates. This machine is an ingenious and valuable contrivance, and it is said will polish a plate in one-sixth of the time required by any other process. The whole done without handling the plate. We hope so.

Gurney has recently taken some of the finest large size Daguerreotypes ever produced. These wonderful specimens are on plates eleven by thirteen inches, called mammoth plates. Such pictures four or five years ago would have filled the world with admiration and surprise. The chemical effect is clear and well worked, thus proving well prepared plates can present large as well as small impressions. It is well worth while for every Daguerreian visiting this city, to look upon these proud specimens of the art.

Thompson of this city, has just taken the whole of the upper floor of the building occupied by him, and has built two fine sky-lights.

We understand that Mr. H. McBride, operator for Meade & Brother of this city, is about to establish himself in Albany. We wish Mr. B. success.

Weston of this city, is now producing some of the best Calotypes we have seen. We are happy to see Photographing on paper brought before the public. Daguerreotypists should call and see Mr. W's. specimens, as well also those produced by Messrs. Bertha, Wehnest, Beekman & Brothers, who have been for some time past successfully practising in the art of "Sun Drawing."

A. Morand has recently made very extensive additions to his former establishment in Chatham street. We now find him lighting his subjects by a large and well arranged sky-light.
