Appletons' CTOLOPiEDiA OF APPLIED MECHANICS of ISYg is a new work, 

 and not a revision of the former Dictionary of Mechanics of 1860. It 

 aims to present the best and latest American practice in the mechanical 

 arts, and to compare the same with that of other nations. It also exhibits 

 the extent to which American invention and discovery have contributed 

 to the world's progress during the last quarter century. Its production 

 is deemed timely in view of the existing popular interest in the labors of 

 the mechanic and inventor which has been awakened by the great Inter- 

 national Expositions of the last decade, and by the wonderful discoveries 

 made by American inventors during the past three years. 



The CoNTRiBOTOES whose names are given above number many of the 

 most eminent American mechanical experts and engineers. Several of 

 their contributions contain the results of original research and thought, 

 never before published. Their efforts have in all cases tended to simplify 

 the subjects treated, to avoid technicalities, and so to render all that is 

 presented easily understood by the general reader as well as by the me- 

 chanical student. Examples are appended to all rules, explanations to 

 all tables, and in such matters as the uses of tools and management of 

 machines the instructions are unusually minute and accurate. 



In semi-monthly Farts, 50 cents each. 

 Subscriptions received only for the entire work of Twenty-four Parti.
