NEOPLASTIC DISEASES. A treatise on 



Tumors. 



By James Ewing. W. B. Saunders Co. 



$14.00 6| x 9I; 112.7 Philadelphia 



A revised and enlarged edition, the 

 third now, of the standard work of 

 reference in English on neoplastic diseases. 

 The classifications of mammary cancer and 

 brain tumors have been altered, and the 

 chapter on tumors of the bones entirely 

 rewritten. 



"The most substantial feature of the 

 revision has been the interweaving of a 

 great number of phrases, sentences, and 

 paragraphs relating to matters of impor- 

 tance, both practical and theoretical." 



The importance of illustrations is recog- 

 nized and a considerable number have 

 been added, but there is still room for 

 improvement in their quality. The 

 general biologist who wishes to get a 

 sound idea of the present state of knowl- 

 edge regarding cancer will find Ewing his 

 best source. 



MONGOLISM. A study of the Physical 

 and Mental Characteristics of Mongolian 

 Imbeciles. 



By Kate Brousseau. Revised by H. G. 

 Brainerd. The Williams & Wilkins Co . 



$4.50 6x9; viii + xio Baltimore 



In this book the authors have brought 

 together and examined all the known 

 theories of Mongolism, a term used 

 to denote a state of congenital men- 

 tal deficiency whose marked physical 

 characteristics are certain superficial 



resemblances to the Mongolian race. In 

 addition they present their own material 

 and information obtained from a ques- 

 tionnaire submitted to workers in various 

 institutions for the feeble minded. From 

 their data they draw the conclusion that 

 most of the causes heretofore suggested 

 for this condition must be discarded and 

 suggest "that Mongolian imbecility is 

 possibly induced by some obscure disturb- 

 ance of the ductless glands." This book 

 will be invaluable to the special worker in 

 this field. A lengthy bibliography is 

 appended.

 general location of the present city.

 physical characteristics of these peoples

 time of the Danish invaders, and in this
