Subtitled 'Theory of Machines', pulleys and kites among them, this volume contains lectures on dynamics and statics, with attendant calculations and diagrams.

Volume contains manuscript notes on general mechanics, and on pulleys and wedges in particular, and wheels and axles. There are subsidiary discussions of things like collision and the mechanics of muscular action. The astronomy notes promised on the book's spine describe how to manage the study of the heavens with big machines. Numerous small diagrams intersperse throughout the book. Some terms appear in Russian.
