 chester ; F.R.S.) METEOROLOGICAL OBSERVATIONS and ESSAYS, first edition, with diagram, 1 }, 8vo. 

 old hf. calf (old name on title) ; very rare, 2. 15s W. Richardson, 1793 



7149 ANOTHER COPY, contemporary tree-calf gilt (VINE AND TALL COPY), or, boards, UNCUT, 3. 10s 



7150 ANOTHER ISSUE OF THE FIRST EDITION, with diagrams, Svo.sewn, 2. 2s T. Ostell [1793] 



The author's first published work, and EXCESSIVELY R\RK in either issue of the above edition. 



The only difference between the above two issues lies in the title-page, which in the case of Ostell's edition has been 

 pasted on to the sheet. A clear inference may therefore be drawn that Richardson's issue was the earlier one. The 

 curious fact of two issues existing of the first edition has hitherto been unknown, and probably points to the slow sale of a 

 new and unknown writer. 



'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 1820. From simultaneous observations at Kendal and Keswick Dalton 

 derived from the aurora of 15 Fob. 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 Agnes M. Clerke.

7152 - ANOTHER COPY, original boards, uncut (covers loose), with author's inscription, 1. 5s 



'Samuel Marshall with respects from the author.' Inscr. on flyleaf. 



1 This second edition is printed verbatim from thejfirst, both text and notes ; and I have only added a few notes at the end 

 under the head of Appendix ; and some observations on clouds, on thunder, and on meteors, particularly the aurora 

 borealis. . . I have been the more anxious to preserve the first edition unchanged, as I apprehend it contains the germs of 

 most of the ideas which I have since expanded more at large in different Essays, and which have been considered as 

 discoveries of some importance.' Preface.

 2. 12s Qd Manchester, 1808-10 



This work, one of the greatest classics of chemistry, which has now become excessively rare, is the first to contain 

 the author's exposition of the ATOMIC THEORY. 



' 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.' Miss Agnes M. Clerke.

'The first attempt to collect scattered facts on the subject, and to explain the main phenomena of the atmosphere by 

 physical laws. He insisted on the paramount importance of extreme accuracy in meteorological observations, and 

 himself kept a model record of atmospheric changes. He organized the plan . . . which became the model from which 

 the Greenwich meteorological reports were developed.' D. N. L.
