TEYPANOSOMIASIS. 525 



food ; obtain for the animal, if practicable, a change of air ; and 

 nurse him carefully. During the period of convalescence, the 

 patient should be liberally fed, and may have an ounce of liquor 

 arsenicalis mixed in his food daily for a week ; and, also, a quart 

 of beer two or three times a day. 



Respecting the South African form of malarial fever in horses, 

 Mr. Hutcheon states that the following treatment is invariably 

 satisfactory, if properly carried out. Give at once: — 



Powdered chloride of ammonium ... jounce. 

 Extract of belladonna ... ... ^drachm. 



Common mass, sufficient to make a ball. 



If given as a draught, the ammonium chloride and belladonna 

 may be dissolved in a pint of warm water. This dose must be 

 given at least three times a day, and continued. It is rare that it 

 requires to be given after the second day. Six doses given at 

 proper intervals are generally enough, but more may be necessary. 

 Do not give purgative medicine, especially aloes, no matter how 

 constipated the bowels are. Put a tablespoonful of sulphate of 

 soda, in the drinking water, twice a day, and give frequent injections 

 of soap and warm water to assist in moving the bowels, but avoid 

 purging. The bowels will begin to act as soon as recovery com- 

 mences. Mr. Hutcheon also advises careful nursing, attention to 

 sanitary rules, and green food. 



Mr. Hoggan found the most successful treatment was a solution 

 of ^ lb. Epsom salts and ^ oz. of ammonium chloride (sal-am- 

 moniac), given twice daily for two or three days, and followed by 

 vegetable tonics. 



Mr. Lund, after unsuccessfully trying many drugs, had extremely 

 good results with the intravenous injection (p. 648) of 2 grains of 

 biniodide of mercury dissolved in water. 



Trypan blue and trypan red by intravenous injection are the 

 nearest approach to a specific known. 



PREVENTION. — Ticks should be destroyed by encouraging tick- 

 birds, starlings, etc. The ticks themselves should be picked off, 

 especially from the neighbourhood of the eyes, nose and mouth, 

 and destroyed, by spraying with kerosine or linseed oil. A good 

 hand-dressing is : 1 gallon of tar ajad 1 pound of resin, gradually 

 stirred into 4 gallons of warm linseed oil. 



Trypanosomiasis. 



Four varieties of trypanosome are found in horses : — 

 1. Trypanosoma Evansi causing Surra. Transmitted by 

 Tabanidse flies.
