Contemporary half-parchment binding with corner pieces and marbled endpapers. A rare collection of important works by the great Milanese physicist and inventor. The first volume brings together his studies on various “airs,” including experiments on deflogisticated air, later identified by Lavoisier as oxygen. The second volume is one of the earliest Italian treatises on lightning rods, featuring practical and theoretical guidance, a detailed description of Franklin’s experiments, and a catalog of lightning rods installed in Europe. Two important first editions by Marsilio Landriani on gas chemistry and electricity
