INTRODUCTION. 
The growing importance of Protozoa from a medical standpoint receives 
abundant confirmation from the following record of the Literature for 1901, 
no less than 50 per cent, of the papers included being of importance in the 
study of the parasitic and pathological relations of the group. It becomes 
increasingly difficult for a Recorder to know where the line is to be drawn 
in dealing with papers of this class, since large numbers of memoirs dealing 
with medical questions now contain references to Protozoa , and yet some 
of them certainly cannot be included without going beyond the zoological 
scope of the Record.
