The Vice-President (Prof. Herdman) in the chair. 
1. Dr. H. B. Fantham exhibited a preparation and 
drawings of a new trypanosome (7. rhodesiense), 
from a case of sleeping sickness contracted in

himself. 
The patient, an Englishman, had never been 
in an area infested by Glossina palpalis, though he 
had been in districts in which Glossina morsitans 
abounded, also in one district in which Glossina 
fusca occurred. 
The trypanosome exhibited long forms, and 
short, stout or stumpy forms with hardly any free 
flagellum. The trypanosome is unique in that 
about six per cent. of the parasites (especially the 
stumpy forms) have the nucleus at the posterior 
(non-flagellar) end, near the blepharoplast, and in 
some cases actually posterior to the blepharoplast. 
These posterior nuclear flagellates can be seen in 
life, by appropriate staining with methylene blue 
or neutral red. Dividing forms of _ this
