 DIORAMA ; with 6 plates illustrating the Apparatus, etc. used, Svo. sewn (VERY SCARCE), 3. 3s 1839 



FIRST EDITION of perhaps the most important work in the whole range of the history of photography, containing the 

 first account of the invention of the Daguerreotype. 



'The discovery of the Daguerreotype was announced in Jan., 1S39, but the details of the process were not made public 

 till August of the same year. It consists of exposing a metal plate covered with iodide of silver for a suitable time in 

 a photographic camera, the plate being afterwards transferred to a dark room, and exposed to the vapour of mercury, which 

 develops the latent image, it being afterwards fixed. Although this process has become almost obsolete, it was really the 

 lirst which was of any practical value, and experts all agree that no other known process renders some subjects e. g. the 

 human face with such fidelity and beauty.' T. C. Hepworth.

The author's first published work, and EXCESSIVELY RARE in the above edition. 



'They contained, as the author remarked 40 years later, the germs of most of the ideas afterwards expanded by him 

 into discoveries. A prominent section comprised the result of six years' auroral observations. He had detected independ- 

 ently the magnetic relations of the phenomenon, and concluded thence auroral light to be of purely electric origin, and 

 auroral arches and streamers to be composed of an elastic fluid of a ferruginous nature existing above our atmosphere. 

 This hypothesis was further developed by Biot in 18-20. From simultaneous observations at Kendal and Keswick 

 Dalton derived from the aurora of 15 Feb. 1793 a height of 150 miles. . . The essay in the same volume was remarkable for 

 the then novel assertion that aqueous vapour exists in the air as an independent elastic fluid, not chemically combined, 

 but mechanically mixed with the other atmospheric gases.' Miss A. M. Clarke.

' In this work he developed those primary laws of heat and chemical combination to which he had been gradually led 

 since 1801, and laid the foundation of chemical notation by representing graphically the supposed collocations of atoms 

 in compound bodies. Extended and revised bodies of atomic weights were added.' Eailcm.
