Amakehe : A Disease of Calves in Uganda. 



2G1 



Lipnphatic Glands. — The prescapular glands are enlarged. One measures 4| inches in 

 length and 1 inch in thickness. On section it is seen to be dark crimson in colour and 

 htemorrhagie. The glands generally are enlarged and hsemorrliagic. Some of them show 

 signs of breaking down into pus. 



Circulatory System. — Heart. — A large quantity of yellow, jelly-like material at the base 

 is seen. There are numerous small petechije into the epicardium. None in the endo- 

 cardium. Muscular substance is pale. Weighs 1 lb. 5 ozs. 



Respiratory System. — Tongue normal. The trachea is full of white froth. Glands at 

 the bifurcation of the trachea are much enlarged and htemorrhagie. Right lung, anterior 

 lobe is dark pur])le in colour and is found to be the seat of a large infarct. Posterior lobe 

 is also the seat of an infarct at the margin, about 3 inches by 2 inches in extent. On 

 section the substance of the lung is extremely cedematous. A large amount of frothy 

 fluid exudes on pressure. Weighs 2 lbs. 10 ozs. Left lung is also the seat of numerous 

 infarcts. On section a large amount of frothy fluid exudes on pressure. Weighs 

 1 lb. 6 ozs. 



Alimentary System.— -Spleen measures 13 inches in length and 4 inches in breadth. On 

 section the substance is soft and friable. Weighs 13 ounces. Liver is enlarged. It is 

 full of flukes. The gall-bladder is distended witli dark, chocolate-coloured bile, which 

 contains many flukes. Weighs 8 lbs. 5 ozs. 



Fourth Stomach. — The mucous membrane of the fourth stomach is congested. It is 

 dark crimson in colour, and numerous small ulcers are seen scattered throughout. 



Urinary System. — Right Kidney. — Capsule strips readily. Under the capsule numerous 

 infarcts are seen, about the size of a pea. On section the substance of the organ is 

 congested. Weighs 8 ounces. Left Kidney. — Capsule strips readily. In the pelvis of the 

 organ there is a quantity of yellow, jelly-like material. Under the capsule there are also 

 several small infarcts. One of these is as large as a small marble. On section the 

 substance of the kidney is seen to be congested. Weighs 5 ozs. 



Experiment 1386. — To study Amakebe in the Calf. 

 July 26, 1909.— Eeceived from Sir Apolo Kagwa. Had also been kraaled at Kampala 

 for some days. 



Aug. 27. — The course of the disease was much the same as in Experiment 1387. The 

 prescapular and other glands became much enlarged, one of them measuring 

 4 inches in length. By this date the calf had recovered, and was returned to 

 owner.
