INTRODUCTION 



The conquest and control of the intestinal protozoan infections of 

 man, which investigation is showing to be both frequent and varied, 

 involves among many other important factors the accurate determina- 

 tion and differentiation of the various flagellate and other proti.stan 

 species of the intastinal fauna. This is fundamental for the detection 

 of etiological factors of disease, especially in view of the prevalence 

 of varied and multiple infections. 



For purposes of comparative protozoologieal investigation and of 

 clinical and therapeutic progress, it is eminently desirable that the
