Image from Harris' Lexicon technicum

This is a second edition of John Harris's famous Lexicon technicum. A kind of contemporary encyclopedia of recent developments in natural philosophy, mathematics, medicine and even architecture, it provides an invaluable guide to early modern science. Harris famously defines natural philosophy as " That Science which contemplates Powers of Nature, the Properties of Natural Bodies, and their mutual Action one upon another".
