The Daguerrotype. – M. Arago’s report has been published, but contains little that has not already appeared in the pages of the Literary gazette. He touches first on the discovery of the camera by Porta, the introduction of the singlr lens, and the invention of the achromatic. He then proceeds to analyse the various preparationsof silver which have been employed in photogenic drawing, and windsup with the immense advantage of the Daguerrotype for copying Eastern monuments, inscriptions, &c., without, however, disclosing what is the substance employed in preparing the plates, and only stating that it is a reactive of much greater sensibility than any hitherto employed. He also alluded to the importance of the discovery, which he contended was proved by the avidity with which the subject has been taken up by other nations, and the trifling pretexts*([i]) they had seized to establish their priority of invention.

([i]) * M. Arago is always sufficiently national, and partial to the claims of his own country and countrymen. In this instance he is evidently unjust to the claims of others. and even more French than usual. – Ed. L. G.
