Later calf, panelled in blind, repairs to front joint.

First editions of an important work leading to the development of the steam engine.

Papin's work, here complete with both parts, contains a description of his invention of the pressure cooker, including a safety valve which would become a technically important development relating to steam power. In addition, the Continuation includes an important description of pneumatic transmission. Papin had worked extensively with Boyle on his air pump experiments, and perceived that water's boiling point was raised when heated under pressure. Supported by Robert Hooke, he demonstrated his "digester" to the Royal Society in 1679. Papin would later develop the first steam engine, based on principles developed here. "The present autoclave in such general use in laboratories, as a steam pressure cooker in kitches, and as a retort in manufactories, is Papin's digester with improvements, and modifications to suit special purposes" (Bitting).
