Proposals for publishing by subscription a complete collection of the works of the Honourable Robert Boyle Esq; printed from the best editions, with considerable improvements and additions from his original manuscripts: particularly letters upon various subjects, written by himself and his friends, and some tracts never before published. To the whole will be prefixed a new account of his life, partly from memoirs drawn up by himself: together with his effects curiously engraven from an original painting, in the possession of Dr. Mead. At the end will be added a complete index.
