The pneumatics

Abstract

Editor's preface -hile the editor of the present work was engaged in writing an analytical history of the steam-engme, it became necessary to consult the antient mechanicians to ascertain who were the inventors of the several parts composing that machine : the earliest writer on the subject appeared to be hero of alexandria ; throughout whose work so many of the elementary parts of all steam-engines, and those also of most other machines are mentioned, that it was thought a translation of hero's pneumatics would be acceptable not only to the engineer but to the scientific world generally.
