and Wants. Svo, paper $0 40 



Under this title is presented a tabular view of 

 the existing scientific schools of the United 

 States, together with many observations on 

 the organization, courses of study, and ad- 

 ministration of such schools ; besides their 

 relations to other, and, especially, prepara- 

 tory education ; the whole being of interest

"The design of this work is to teach Geome- 

 trical Drawing, as applicable to all industrial 

 pursuits, in a simple, practical manner, to 

 persons even who have made no attainments 

 in Elementary Mathematics. For this pur- 

 pose the method recommended is the oral 

 one, in which each operation will be per- 



formed by the Teacher before the eyes of the 

 pupil, by whom in turn it will be repeated. 

 It is hoped that the work will also be found 

 useful to all who are preparing themselves 

 for any of the industrial pursuits in which 

 Geometrical Drawing is required/'
