FIRST EDITION of Cavallo’s large treatise, published as a handsome quarto at his own expense, on the physics and composition of the atmosphere, “a judicious examination of contemporary work, particularly Priestley’s, presented from a nondogmatic phlogistic point of view” (DSB). He gives a short introductory course of chemistry, describes an improved air pump and eudiometer, and gives an account of some extensions of the experiment by Ingenhousz on the influence of light on the growth of plants, among much else. Cole 236. Duveen pp. 127–128. This was the only edition in English.
