DALTON. 748 DALY. the University of Edinburgh. His chief physical researches were those on the constitution of mixed gases, on the force of steam, on the elasticity of vapors, and on the expansion of gases by heat. In chemistry he distinguished himself by his progressive development of the atomic theory (see Chemistry), as also by his researches on the absorption of gases by water, on carbonic acid, carburetted hydrogen, etc. His papers are mostly contained in the Memoirs of the Lit- erary and Philosojihical, Hociety of Manchester, the Philosophical Transactions, Nicholson's Philosophical Journal, and Thomson's Annals of Philosophy. Besides these, we have his Meteoro- logical Essays and Obserrutions (London, 1793; 2d ed. 1834). Profound, patient, and intuitive, Dalton had precisely the faculties requisite for a great scientific discoverer. His atomic theory has revolutionized the science of chemistry and has yielded a greater number of valuable results than, perhaps, any other idea ever introduced into physical science. In his habits, Dalton was simple; in his manners, grave and reserved, but kindly, and distinguished by his trutlifulness and integrity of character.
