 Mechanical Engineering in the Stevens Institute of Technology,

 '^ Professor Thurston almost exhausts his subject ; details of mechanism are followed 

 by interesting biographies of the more important inventors. If, as is contended, the 

 steam-engine is the most important physical agent in civilizing the world, its history 

 is a desideratum, and the readers of the present work will agree that it could have a 

 no more amusing and intelUgent historian than our author." — Boston Oazeite.

"The study of spectrum analysis is one fl'aught with a peculiar fascination, and 

 some of the author^s experiments are exceedingly picturesque in their results. They 

 are so lucidly described, too, that the reader keeps on, irom page to page, never 

 flagging in interest in the matter before him, nor putting down the book until the last 

 page is reached."— .tVezo York Evening Express.
