The temperature in the tables is recorded according to the haema- 
tothermic scale of one of us (R.R. ), where temp. = (F. — 95) x 10; 
F. being the temperature in degrees Fahrenheit recorded by a 
clinical thermometer. Temperature was taken in all cases per 
rectum. The counts of Guinea-pigs 1 and 2 are not given. For the 
counts of Guinea-pigs 3 and 4 see paper on ‘ Enumerative Studies on 
Trypanosomes,’ by Fantham and J. G. Thomson, where Guinea-pig 
3 is numbered as 7, and Guinea-pig 4 is numbered as 6.
