John Dalton and the origin of the atomic theory: reassessing the influence of Bryan Higgins

  • MARK I. GROSSMAN (a1)
Abstract
Abstract

During the years 1814–1819, William Higgins, an Irish chemist who worked at the Dublin Society, claimed he had anticipated John Dalton in developing the atomic theory and insinuated that Dalton was a plagiarist. This essay focuses not on William Higgins, but on his uncle Bryan Higgins, a well-known chemist of his day, who had developed his own theories of caloric and chemical combination, similar in many respects to that of Dalton. New evidence is first introduced addressing Bryan's disappearance from the scientific community after 1803. In his later years, Bryan apparently suffered from a condition resulting in a decline in his mental health, which explains why he never lodged any priority claims of his own against Dalton, or defended those of his nephew. Dalton's mention of Bryan's name in Part II of A New System of Chemical Philosophy, his laboratory notebook entries, and a fresh look at his correspondence with chemist Thomas Charles Hope indicate that Dalton adopted a Higgins-like caloric model in 1803. Together these factors provide evidence to support the argument that Dalton learned of Bryan's theories via a meeting he had with William Allen on 10 July 1803. Existing evidence related to the origin of the atomic theory is worthy of re-examination in light of Dalton's possible prior knowledge of Bryan's work.

20 Bryan used the same modus operandi with the Royal Institution, offering initial services at no cost, to secure his consulting position in Jamaica. JAJ, op. cit. (17) (1808) 9, p. 584. The Royal Institution was actively seeking to fill lectureships, and Bryan may have been seeking an appointment, based on his earlier attempt to replace Adair Crawford at the Royal Military Academy, Woolwich. Higgins's report on the laboratory was filed with the rough minutes suggesting that he found nothing of significance or that he was a victim of politics, with Davy protecting his turf, using his influence with the managers to minimize the importance of any of Higgins's findings about the laboratory. No rough or draft minutes prior to 1848 are held by the Royal Institution. Personal communication from Jane Harrison, Royal Institution, 17 September 2013.

Also see Unwin Patrick and Unwin Robert, ‘Humphry Davy and the Royal Institution of Great Britain’, Notes & Records of the Royal Society (2009) 63, pp. 733 , 17. Contrary to Unwin and Unwin, the evidence suggests that Higgins approached Davy offering to review the laboratory.

21 According to Sullivan, op. cit. (2), p. 484, Bryan apparently acquired his estate through his marriage to Jane Welland.

32 Grossman, op. cit. (11), pp. 344–345. Dalton's laboratory notebook entries show that he may have already been aware of Bryan's work on heavy inflammable air in October 1803, when Dalton began experiments on gaseous compounds of carbon, including the heating of wet charcoal and the incomplete combustion of ether. Roscoe Henry and Harden Arthur, A New View of the Origin of Dalton's Atomic Theory, London: Macmillan, 1896, pp. 5960 . Bryan referenced experiments on the combustion of ‘the heavier inflammable air carrying ethereal vapour’ in Acetous Acid. Higgins, Experiments and Observations Relating to Acetous Acid, op. cit.

50 Hope's letter referencing Dalton's 8 November response is undated, but Hope's next letter to Dalton is dated 29 March 1804. Roscoe and Harden, op. cit. (32), p. 138. Roscoe and Harden arranged the letters chronologically for all of the correspondents, so Hope's undated letter was apparently written before 29 March 1804. Furthermore, in the undated letter, Hope describes experiments he conducted addressing the density of water as a function of temperature, stating, ‘I know not whether they will seem as decisive to you as they do to me’. Roscoe and Harden, op. cit. (32), p. 136. Dalton's laboratory notebook contains an entry referring to ‘a repetition of Hope's experiment’ on 16 December 1803. Roscoe and Harden, op. cit. (32), p. 61. Based on the chronological order of the letters and Dalton's reference to Hope's experiments, the undated letter likely dates from mid-November to early December 1803. Hope read his paper on the density of water on 9 January 1804, and stated, ‘It was in consequence of a communication with which Mr. Dalton favoured me, three months ago, that my attention was directed to this subject’, indicating that his meeting with Dalton in Manchester probably occurred sometime in early October 1803. Hope Thomas, ‘Experiments and observations upon the contraction of water by heat at low temperatures’, Transactions of the Royal Society of Edinburgh (1805) 5, pp. 379405 , 384.

51 Roscoe and Harden, op. cit. (32), pp. 134. Dalton's 8 November response may reflect the caloric model he had in mind in August 1803, which, according to his laboratory notes, was the month during which he conducted his latest experiments on gaseous diffusion. Roscoe and Harden, op. cit. (32), p. 59.

52 Many eighteenth- and early nineteenth-century chemists had various loose notions of caloric surrounding particles. For example, Thomson mentioned the term ‘atmosphere of caloric’ once in System of Chemistry. Thomas Thomson, A System of Chemistry, vol. 3, Edinburgh: Bell & Bradfute, and E. Balfour, 1802, p. 236. But Thomson and others did not allude to the diameter of the caloric atmosphere as a measure of atomic size, nor did they use language that closely matched Dalton's wording in his laboratory notebook, as is the case for Bryan. In fact, Thomson's use of the phrase occurs in the context of a discussion relating to Boscovich's atomic model, in which atoms are dimensionless point forces, with no diameter at all. See Mauskopf Seymour, ‘Thomson before Dalton: Thomas Thomson's considerations of the issue of combining weight proportions prior to the acceptance of Dalton's chemical atomic theory’, Annals of Science (1969) 25, pp. 229242 , 236.

61 In 1812, an anonymous author using the initials ‘LOC’ noted that Dalton's caloric model described in Thomson's System of Chemistry was similar to Bryan Higgins's caloric model described in Acetous Acid and attributed priority for the caloric model to him. LOC, An attempt to explain the phenomena of caloric’, A Journal of Natural Philosophy, Chemistry, and the Arts (1812) 31, 95107 , 106. Although LOC's correspondence was overlooked by the scientific community at large, Dalton almost certainly read the correspondence and knew of LOC's comments about Bryan's priority for the caloric model. Dalton had the 1812 volume of Nicholson's Journal in his personal library at the time of his death, he submitted numerous papers to the periodical throughout his career, and his publications reflect his intense interest in the subject of heat, so it is difficult to support the position that he had overlooked LOC's paper.
