An Introduction to Science 



By BERTHA M. CLARK, Ph.D., Head of 

 Science Department, William Penn High 

 School, Philadelphia. 494 pages. Price, $1.20 



"Dr. Bertha Clark has attempted, 

 sncoessfnlly, to build up a body of 

 scientific material for freshmen in 

 high school, drawn from the problems 

 of a scientific natnre -which confront 

 the pupils in their home life and out- 

 door life. The book is, therefore, not 

 'pure science' but 'humanized science' ; 

 and the author attempts to organize 

 these problems and their solutions so 

 as to leave the pupils with a scientific 

 point of view of their problems and 

 their solution. Hence we have an 

 introduction to science of a kind likely 

 to be of great value to the pupil."

VOLUME II PART I 



Theory of the Functions of a 



Complex Variable 



Since its appearance in translation Volume 

 I has exerted a widening influence in American 

 mathematical circles. Volume II has long been 

 favorably known in its original French. It 

 has been radically revised and this volume is 

 an authorized translation. Both volumes in 

 the American edition are noteworthy for excel- 

 lence of workmanship and strict accuracy of 

 translation. Volume H issued in two parts 

 bound separately covers the theory of functions 

 of a complex variable and the theory of differ- 

 ential equations.
