The plasma of the trypanosoma appears blue, the flagellum red 

 and the chromatin of a different shade of red. It may be perma- 

 nently mounted in balsam. 



Mortality. The disease is constantly fatal in horses, though 

 the animal may survive for months. 



SURRA IN CAMELS. 



Haggar describes this as having remissions or intermissions as 

 in the horse, the trypanosoma disappearing during the intervals 

 to appear with the hyperthermia. The temperature may rise 

 to 106° F. and the animal wastes away to a veritable skeleton. 

 A remarkable feature of the disease is the formation of immense 

 abscesses containing a thick, cream-colored pus on the sides of 

 the chest in the vicinity of the pad, and in the sheath and scrotum 

 ■or udder near to the stifle pad. The mortality is nearly as great 

 as in the horse or mule, yet the camel- drivers say that a small 

 percentage recover. 



SURRA IN BOVINES. 



The domestic ox, the sacred cow of India (I^ingard) and the 

 water buffalo (caribao) of the Philippines contract Surra. It is 

 interesting to notice that in these animals the disease is relatively 

 mild and recoveries are frequent. 



In the Indian buffalo it causes dulness ; advancing emaciation ; 

 slight temperature variations ; muco-purulent inflammations of 

 the conjunctiva, cornea, and pituita ; and occasionally eruptions 

 tinder the breast or belly. 



Among lesions were atrophy, softening of lymph glands, en- 

 larged liver and spleen (slight), petechise and blood extravasa- 

 tions on the pericardium, epicardium and other serosse, and on 

 the intestinal mucosa which sheds its epithelium in patches. •
