Goats. 
Rhodesian strain. Three experiments. In these animals the 
disease ran a fairly rapid course. Parasites were not infrequently 
seen in the blood, but in very small numbers only, and the posterior 
nuclear variety was never found. The only symptoms observed 
were : loss of weight, oedematous swellings—accompanied by slight 
loss of hair—of the skin and subcutaneous tissues over the nasal 
bones and beneath the eyes, and interstitial keratitis. The 
temperature of Goat i rose to io 7°F. on the seventh day after 
inoculation, but quickly returned to normal (i03-4°F.). The other 
two animals never exhibited any rise of temperature. Incubation 
period, four to eleven days; average seven days. Duration, 
forty-five to fifty-five days; average eight days.

T. gambiense. Two experiments. Both animals became 
infected, but the disease was exceedingly chronic. Parasites have 
never been found in the blood of Goat 1, but two rats, inoculated 
with its blood on the forty-fourth day, became infected after an 
incubation period of twelve days. The animal is still alive, m° rL 
than five months after inoculation, and has presented no symp tonls 
of disease. Rats inoculated with its blood, on the hundred and
