TRYPANOSOMIASIS EXPEDITION TO SENEGAMBIA 
17 
Cases of Trypanosomiasis Observed Amongst the Natives of Gambia 
Case I. — Woman, age thirty-five years, living at Lammin Village, on the 
Lam mi 11 Creek, Kommbo. 
History . — The woman was married and had one child seven years old. She was 
a native of the town. 
She complained of feeling weak and ill, and asked for medicine. She said 
her illness commenced a month ago with a cough and lever, the fever at times, for a 
day or two, confining her to her hut. She related that during the rains she had been 
ill with fever and headache and that she had got much thinner. 
Note. — History unreliable. 
Clinical Examination. — Patient was a spare Mandingo woman, showing no 
signs of wasting and no skin lesions. There was a slight oedema around 
ankles, the skin ' pitting.' One lymphatic gland in the left axilla, though freely 
movable, was distinctly enlarged ; all the other superficial glands were palpable. 
The liver, spleen, heart, lungs, kidneys, and intestines were all normal. 
Pulse, 93 ; respiration, 1 8 ; temperature not recorded. 
Blood. — Coverslip preparations were examined on two successive days. The 
first observation showed one, the second five parasites to the coverslip.*

Four hundred cells from one slide were counted. 
Case 2. — Boy, age nine years. Living at Lammin village. 
History. — He had never been far away from the village. Though he was said 
by his parents to be weakly he had had no serious illness, and worked with other 
boys of his age on a ground-nut farm in the neighbourhood. 
No definite history could be obtained. 
Clinical Examination. — Patient was a rather poorly-developed lad. Nothing 
abnormal was detected, except the enlargement of the spleen usually seen in natives of 
this age. This boy could run and wrestle as well as other boys without any marked 
increase in the frequency of pulse or respiration. 
As previously stated three-quarter inch square coverslips were used throughout our work.
