TRYPANOSOMIASIS EXPEDITION TO SENEGAMBIA 
3 1 
Case VI. — Small black stallion ; age eight years. Owned by an officer ot the 
West African Frontier Force. 
History. — This horse has been in Bathurst for four years, and during this time 
has always been well. Ot its previous history nothing was known. At the beginning 
of October, 1902, he was taken into foreign Kommbo, and on his return to Bathurst 
he had an attack ot 'rheumatism' affecting his hind-quarters. 
Clinical Examination. — He was examined on October 30, 1902, and found 
to be infected with trypanosomes. At this time he was sleek and in excellent condition. 
His owner stated, however, that the pony was not as vivacious as before the journey 
through Kommbo, and was not so hardy as he had been a year previously. 
To one seeing the pony tor the first time there was absolutely nothing to 
sug»;est ill-health. There were no oedemata, no listlessness, and no emaciation. There 
was no perceptible dragging ot the hind legs or slackness in gait. The temperature 
varied, being usually about 102° F. Parasites were only periodically seen in the 
peripheral blood. 
We have never observed any oedemata, haemorrhages, or paralysis mthis horse. 
We have seen slight discharges from his eyes, but this was probably due to an inter- 
current conjunctivitis. The genitals were relaxed, as is often the case, and conveyed 
the idea of enlargement without being really swollen. 
Parasites were never very numerous in the blood of this horse and appeared 
periodically. 
We purchased the animal towards the end of December, 1902, and have had 
it continuously under observation until the present date. The animal is still in 
apparently fair condition, and looks better than in March last when it was very thin 
and weak. 
The temperature has been usually from ioo° to io2°F., with periodic rises to 
103 0 F., when parasites were often seen. The following chart gives the tempera- 
ture curve ot this case, and shows how frequently parasites were absent from the 
peripheral blood. 
Urine was alkaline, Sp. gr., 1,042, and never contained albumen or blood.

Case VII. — Stallion, Joubert, aged eleven years, owned by French Government. 
Stationed at Maka. 
History* — This horse came two years previously from Thies. It had not 
been well for a year. ' Its feet, legs, and sheath had first become swollen.' This 
had been later followed by a fulness ot the loins and by a general enlargement ot 
the horse's belly. 
When we saw this and the following case they were both apparently in excellent 
condition. We could detect no oedema, though the usual relaxation and apparent 
* The hisiones of Cases VII and VIII, with the account ot their illnesses was given to us by Monsieur Porthes. We 
take this opportunity of again thanking him for the aid whicli he gave us in our work.
