(1803)
(London, W. Bulmer and Co., 1803). 4to. No wrappers as extracted from ""Philosophical Transactions"" 1803 - Part I. Pp.29-42 and 1 engraved plate and Appendix: pp. 274-276. With titlepage to the volume Part I. A paperflaw in margin of the first leaf, neathly repaired, no loss. The plate with a few small brownspots. Verso of titlepage with a small stamp, otherwise clean and fine, wide-margined.
First appearance of this highly importent paper in which Henry announced his discovery of the law, which later was termed ""Henry's Law"". The law states that when a gas is absorbed in a liquid the weight of the gas dissolved is directly proportional to the pressure of the gas over the liquid. This discovery contributed directly to the atomic theory of Dalton.(Parkinson: Breakthroughs: 1803 C) ""Dalton's own experiments on the solution of gases and the stimulus afforded by Henry's work have been seen as crucial in the development of the atomic theory.""(DSB VI p. 285).A paper by Humphrey Davy: ""An Accont of some Experiemnts and Observations on the constituent Parts of certain astringent Vegetables"" and on their Operating in Tanning. Read February 24, 1803"", comes with. In the same volume Pp. 233-273.

(1808)
(London, W. Bulmer and Co., 1808). 4to. No wrappers as extracted from ""Philosophical Transactions"" 1808 - Part I. Pp. 63-95 (Thomson) and pp. 96-102 (Wollaston:). Clean and fine.
First appearance of these two historical papers in chemistry in which Thomson and Wollaston, independently, presents experimental proofs of John Dalton's ""Law of Multiple Proportions"", and thereby laying the foundations of the Atomic Theory. - These demonstrations went far to influence chemists favorably toward Dalton's atomic theory. ""In January 1808 Thomson was the first to submit an experimental illustration of the law of multiple proportions, doing so at least four months before the publication of Dalton's ""New System of Chemistry Philosophy"" (1808). This paper, ""On Oxalic Acid"" also established a usefull method of determining empirical formulas.""(DSB XIII, p. 373).""This paper is also importent as he here introduces quantified chemical symbolism for compounds, a compound with, for instance, two parts oxygen (w) and one part carbon (c) being denoted by 2w + c."" (Parkinson in ""Breakthroughs"", 1808 C).""In 1808 he (Wollaston) described his experiments on carbonates, sulfates, and oxalates, which proved that the composition of these substances was regulated by the law of multiple proportions. These additional instances of the law were easely verifiable and were often mentioned as standard examples. Wollaston accepted that his findings were merely particular instances of Dalton's assertion that the atoms of elements united one to one, or by simple multiple relation.""(DSB XIV, p.488).
