work has been performed in a very thorough manner. The 

 section upon History and Distribution which naturally includes 

 synonymy is particularly well executed, a map of the world and 

 one of the United States showing the geographical distribution 

 of pellagra being given. 



While discussing the subject in general, the volume deals with 

 it more directly as found in the South Atlantic portion of the 

 United States. Doctor Roberts has seen the disease in Italy, and 

 hence writes at first hand of pellagrous conditions in that country. 

 It is obvious also that he has been in close personal touch with 

 many of the investigators v/ho have contributed largely to our 

 present knowledge of the disease. 



Symptomatology should have been included in the title. This 

 section together with that on diagnosis apparently embraces 

 most of the author's personal observations. A complete bib- 

 liography of the important literature on the subject would have 

 added to the value of the volume.

This book is designed for the use of students and practitioners, 

 and it is to be commended for its marked lucidity and brevity in 

 discussing laboratory diagnostic methods accepted by laboratory 

 workers up to the date of its publication. Naturally it contains 

 little that cannot be found in other publications on the same 

 subject. The illustrations by Katharine Hill are excellent. 



The portions of the volume which deal with the parasites of 

 man are poorly executed; they are incomplete, and well-knowTi 

 rules of zoological nomenclature have been disregarded.
