Physics for Technical Students 



Mechanics and Heat

 College. 349 pages, 6x9, 150 illustrations, $2.00 (8/4) net, postpaid. 

 Professor Anderson has prepared this text on Mechanics and Heat under the general 



title of " Physics for Technical Students." He has aimed to present the subjects from 



the practical side for the great number of students preparing for work in engineering and 



agriculture. 



Special attention is given to the treatment of Force, Torque, Translatory Motion 



and Rotary Motion, because these underly so much of the subsequent work of the student.

 Geology, Massachusetts Insti- 

 tute of Technology; formerly 

 Geologist of the U. S. Geological 

 Survey.

A description, by classes and 

 type examples, of the occurrence, 

 structure and origin of the prin- 

 cipal deposits of metallic and 

 non-metallic minerals. 



It does not attempt to cover 

 coals, hydrocarbons and struc- 

 tural materials. Little space is 

 given to statistics, while the 

 problem of correlation and origin 

 are treated fully.

 mark a definite change in the 

 current of study."

Igneous Rocks 



and Their Origin 



By Reginald Aldwoeth

This book is planned to meet 

 the needs of those who desire

 igneous rocks, or the more signi- 

 ficant facts about them. 



Part I is a summary of these 

 facts, with a number of contri- 

 butions thereto, a large part of 

 which can be described quanti- 

 tatively. 



Part II treats of these facts in 

 the light of the earth problem as 

 a whole. 



Part III treats them in relation 

 to the comprehensive theory 

 outlined in Part II.

Manual of 



Petrographic 



Methods 



By Albert Johannsen, Ph.D., 

 Assistant Professor of Petrology, 

 The University of Chicago.

 tions, $6.00 (25s) net, postpaid. 



There is no work in English 

 which gives complete informa- 

 tion on modern petrographic-mi- 

 croscopio methods. Dr. Johann- 

 sen has filled this gap with a 

 work of broad scope, requiring 

 years of research and labor. 



It is designed as a reference 

 work for specialists and a text 

 book for advanced students.
