First edition of the valuable and important collection of 58 of d’Alembert’s most notable memoirs on mathematical, astronomical, optical and mechanical subjects which he contributed to the Paris and Berlin Academies after 1760. They include many new solutions to problems he had previously attempted. It is the best collection of his mathematical articles that exists, and includes his extensive writings on optics between 1760 and 1770, virtually all of which were devoted to the theory of lenses. DiLaura, Bibliotheca Opticoria, 454. Despite the bookplate this does not appear in Roberts & Trent, Bibliotheca mechanica.
