 thorized Translation from the Author's Corrected Te^c. By Morton 

 Masius, M.A., Ph.D., Professor of Physics, Worcester Polytechnic Institute;

The recent remarkable developments of physical theories, especially those 

 concerned with relativity and quanta of energy, cannot fail to have far-reaching 

 influences on philosophical thought. Professor Rougier's very wide reading in 

 mathematical and experimental physics has enabled him to present and interpret 

 the new advances in physics in a way which should prove of great interest to 

 both philosopher and physicist. The book marks a measurable advance toward 

 a confluence of the broad streams of philosophical and scientific enquiry.

Textbook of Organic Chemistry 



By Joseph Scudder Chamberlain, Ph.D., Professor of Organic Chemistry, 

 Mass. Agricultural College. 8vo. XLiii -f 959 Pages. Cloth, $4.00 Post- 

 paid. 



The growth of chemical industry in this country during recent years has 

 created new interest and an increased demand for training. This is more notice- 

 able in organic chemistry than in any other particular field, and has led the 

 author to prepare a new book which aims to impress the student with the great 

 importance and general interest of the subject, leading him through rather than 

 around the difficulties. He is made to realize the direct connection of theory 

 with the tremendous industrial application of organic chemistry in the life of 

 the world.
