YEAST-LIKE FUNGI OF HUMAN INTESTINAL TRACT 47 



one of these characters when taken alone is sufficient to identify the 

 species and any or all of them vary under some conditions. 



Fourteen cultures isolated from the intestinal tract were carefully 

 studied and compared with known species. Of these, 11 were evidently 

 different and distinct species, while 3 were sufficiently like Parasac- 

 charomyces Candida (Monilia Candida Bon.) to warrant placing them 

 in this species. 



I gratefully acknowledge the very helpful assistance of Dr. F. L. Stevens, 

 Professor of Plant Pathology, University of Illinois, throughout the prepara- 

 tion of this thesis. I wish also to express my appreciation of the suggestions 

 made by Prof. William Trelease, Head of the Department of Botany, Uni- 

 versity of Illinois, concerning the taxonomic questions involved. Thanks are 

 also due Dr. H. D. Singer, Director of the State Psychopathic Institute, Dr. 

 B. K. Ashford, of the Institute of Tropical Medicine and Hygiene, San Juan, 

 Porto Rico, and others who have furnished material and cultures for this 

 investigation.
