= This edition of Boyle's important work on effluviums comprises 3 parts, of which the 1st part is subsequently divided in 5 parts, each having a separate title: 1. Strange subtitly of effluviums 2. Determinate nature of effluviums 3. Great efficacy of effluviums 4. New experiments to make fire and flame ponderable 5. A discovery of the perviousness of glass. The 2nd part is an essay on the origins and virtue of gems by Boyle and the 3rd part is an English translation of Steensen's work on solids (1st ed. De Solido intra solidum naturaliter contento, Florence, 1669) (these parts erroneously paginated but complete). This edition contains the title-page to part 1 as the 2nd preliminary leaf described under Fulton 106 as well as the title-p. described under 107. Fulton 107; PMM 141; Wing 3952. "Effluviums is one of the most important but perhaps less widely known works of Boyle and a most significant one. Had Boyle been bolder in his conclusions which he drew from his experiments on oxidisation, he would have forestalled phlogiston theory which was problematic to chemistry in the eighteenth century."
