ease as prevailing during the rainy season, and say it abates or 
temporarily recovers upon the cessation of the latter, or upon 
removal of animals to dry hills. It is scarcely noted elswhere 
in the old world. 
It is reported in the United States by Dr. Waugh in Cali¬ 
fornia, Arizona, New and old Mexico, by Dr. Hinebauch, fre¬ 
quently, in Dakota, by Dr. W. B. Niles in Iowa, by Dr. Stew¬ 
art in Nebraska and Kansas, by Dr. Mayo in Kansas, by Dr. 
Y. A. Johnson in Iowa, by Dr. Lemay in Kansas, by Dr. J. S. 
Butler in Minnesota, by Prof. Bitting in Florida. 
It prevails extensively throughout central Illinois. I have 
seen it in Indiana, and it is met with occasionally in Montana. 
It rarely assumes a fatal type in the United States, but is persis¬ 
tent. It recovers spontaneously, but, as a rule, upon the ap¬ 
proach of cold weather, to reappear at the same part in worse 
form upon the return of hot weather. While heat and moisture 
seem to play an essential part in its prevalance and character in 
India, heat seems the essential factor here and determines its 
existence regardless of humidity, altitude, food, housing, care or 
other environments. The source of the infecting agent seems 
wholly unknown. 
In not too severe cases it yields fairly well to treatment 
when consisting of the destruction of a large pait of all the 
germ-containing tissues, followed by dessicating, antiseptic 
dressings. 
The disease, I have for want of a better name termed en¬ 
zootic spasm of the larynx, has been very rarely and indiffer¬ 
ently described and seems from all reports to be rare in the 
United States. 
Veterinarians Joseph Leather & Sons, describe an outbreak 
of this disease under the head of lathyrns-poisoning in the 
horse, and attribute the disease to the feeding of lathyrns sat- 
iva, or indian vetch. In this outbreak twenty-one out of thir¬ 
ty-five horses attacked were destroyed. In the same article 
reference is made to cases of the same lathyrns poisoning occur¬ 
ring in the practice of Dr. McCall.
