Seventh edition of Ferguson’s valuable lectures, for many years a standard work on the mechanical sciences. Ferguson (1710-1776), astronomer, instrument-maker and accomplished public lecturer, was a great proponent of Newtonian philosophy. He published several technical papers on eclipses, celestial globes and horological instruments. “His models of the solar system were classics of engineering designs whose accuracy far surpassed anything previously available” (DSB IV, p. 565). Included in this work is the supplement, containing additional plates not found in the first edition.
