HIGHER ALGEBRA 



By HERBERT E. HAWKES, Professor of Mathematics in Columbia University. 8vo, 

 cloth, 222 pages, with diagrams, #1.40. 



WHILE this text does not emphasize the applications of algebra to the detri- 

 ment of a thorough development of the subject itself, it is especially adapted for 

 use in technical schools. A concise but illuminating review of elementary algebra 

 is followed by a comprehensive discussion of the quadratic equation and the 

 more advanced topics, including series. The reasonable use of graphical methods, 

 care in finding the limit of error in numerical computations, the omission of 

 inexact digits in computation, and the use of tables for extracting roots are all 

 features which are in accord with modern instruction in applied mathematics. 



THE MATHEMATICAL THEORY OF HEAT 

 CONDUCTION 



By L. R. INGERSOLL, Associate Professor of Physics, and O. J. ZOBEL, formerly 

 Fellow in Physics in the University of Wisconsin. 8vo, cloth, 171 pages, $1.60. 



THIS text in Fourier's Series and Heat Conduction presents along with the 

 theory a large number of practical applications. Since only a moderate mathe- 

 matical knowledge on the part of the student is assumed, the book may be used 

 as a first course in mathematical physics. 



It will] also prove of especial service to geologists and engineers. Questions 

 of the cooling of the earth, with and without radioactive influences, and several 

 cases of cooling magmas are among the problems included for the geologist; 

 while in technical lines, problems in the tempering of steels, freezing of concrete, 

 electric welding, and twenty-odd other examples many of them here treated 

 for the first time are considered. 



THEORY OF FUNCTIONS OF REAL VARIABLES 



By JAMES PIERPONT, Professor of Mathematics in Yale University. 

 Volume I 8vo, cloth, 560 pages, illustrated with diagrams, $4.50. 

 Volume II 8vo, cloth, xiii + 645 pages, illustrated with diagrams, $5.00. 



A COMPREHENSIVE and scholarly treatment of the subject designed to acquaint 

 the reader with the processes and methods of reasoning peculiar to this branch 

 of mathematics. Volume II includes much original material here presented for 

 the first time and leading to results more general than any yet obtained in this field. 



A most admirable exposition of what in modern times have come "to be regarded as 

 the unshakable foundations of analysis. Hitherto, in order to gain a knowledge of the 

 best that has been done in the subject, it has been necessary to repair to foreign institu- 

 tions ; now it is no longer necessary to have recourse to foreign tongues, thanks to 

 Professor Pierpont's simple and scholarly presentation. The Nation.
