somes found, others motionless, apparently dead. In 
the smears made a fair number of trypanosomes were 
found, mostly of stouter form, often very vacuolated, and 
with N broken up (figs. 81-82) ; one slender form, apparently 
much macerated, was found. No dividing forms were seen. 
Second batch, Nov. 20th—A number of Tenio- 
rhynchus fed on Monkey 478. Some were dissected after 
forty-eight hours (Nov. 22nd) ; in one a motile trypanosome 
was seen, but in the smear made from this none were found. 
The four remaining were dissected after seventy-two hours 
(Nov. 23rd); the blood had become reduced to a mass of 
dancing granules, amongst which blood-corpuscles were 
absent or very rare. In three of the mosquitoes no trypano- ~ 
somes were found ; in the fourth some active trypanosomes of 
stout type were found, but in the smear made none were found. 
The experiments with Stomoxys and mosquitoes were 
highly incomplete, and it is to be regretted that more were not 
carried out; but so far as they go they show one interesting 
result, namely that the trypanosomes become differentiated 
into exactly the same two forms, stout and slender, as they 
do in Glossina. Further, the trypanosomes in the digestive 
tract one day after feeding appeared to have multiplied, as 
judged both by their number and by the frequent occurrence 
of dividing forms. 
Examination of Lice from Sleeping Sickness 
Patients. 
The Father Superior of the Sleeping Sickness Refuge, 
conducted by the Algerian White Fathers at Kisubi, kindly 
caused lice to be collected for me from patients in three 
degrees of the disease—early, medium, and late. I dissected 
ten lice of each batch and examined all their organs very care- 
fully. ‘he gut contained in all cases numerous cocci of fair 
size, in couples or clusters; the hinder part of the intestine 
frequently contained very large, active, rod-shaped bacilli. 
No trypanosomes were found in any case.
