  1. This sketch is condensed from lectures originally written for delivery to an audience of engineers and mechanics, at the Stevens Institute of Technology, in the winter of 1871-'72, and from lectures since prepared for classes in the Department of Mechanical Engineering, and revised to date. The most novel portion—referring to the practical realization of the "perfect steam-engine" is here more fully developed than it had previously been, and the paper, as a whole, is for the first time here published. The illustrations are principally from Stuart and Farey, and from the article "Steam-Engine," prepared by the writer of these lectures for Appletons' Cyclopædia, new edition. A very complete history of "The Growth of the Steam-Engine" has been prepared by
