PRINCIPLES OF MECHANISM,

By ROBERT WILLIS, M.A., F.R.S., &c., 



Jacksonian Professor of Natural and Experimental Philosophy in the University 



of Cambridge. 



"All readers whose pursuits have led 

 them to give any special attention to the 

 general principles involved in the countless 

 varieties of mechanical contrivances em- 

 ployed in manufacturing processes and in 

 the commonest operations of life, will be 

 glad to learn that Professor Willis has at 

 last published a second edition of his 

 1 Principles of Mechanism ;' a book which 

 on the publication of the first edition, just 



thirty years ago, immediately became the 

 standard work on the subject of which it 

 treats, and has in this long interval never 



yet been superseded Altogether this 



work is one of the most valuable as well as 

 the most original contributions to the lite- 

 rature of practical mechanics that our own 

 or any country has produced, and is one 

 that no mechanician will think of doing 

 without." — Examiner.
