THE parasitic ICTERO-HAEMATURIA OF SHEEP. 
By W. L. Williams, V. S., Prof, of Surgery and Obstetrics, New York State 
Veterinary College, Ithaca, N. Y. 
Under date of July ist, 1895, was published as a part of 
Bulletin No. 8, of the Montana Agricultural Experiment Station, 
some preliminary investigations regarding an outbreak of para¬ 
sitic ictero-haematuria, or red water and jaundice of sheep, a 
disease heretofore described, so far as we know, only by Profs. 
Babes, of Roumania, and Bonome, of Italy. Since the publica¬ 
tion of Bulletin No. 8, no outbreaks of the disease have been 
reported outside the area originally infected, and no reliable in¬ 
formation has been gleaned to indicate the existence of this fatal 
malady anywhere in the United States, except in the Silver 
Bow and Deer Lodge Valleys, near Butte, Mont. The subject 
is one of great scientific interest, and while of economic impor¬ 
tance in a very limited area only, the possibility of other sheep 
ranges becoming similarly infested lends to the subject sufficient 
importance to warrant further study of its nature, and led me to 
keep as close watch as possible regarding its further continuance 
and spread. 
The preliminary account of the disease, published in Bulle¬ 
tin No. 8, appeared in full in the Veterinary Magazine (Phila¬ 
delphia), Vol. II., p. 497. 
In the meantime the disease had abated, several owners sold 
the remnants of their herds, and nothing more was known of the 
malady until on May 28th, this year, a telegram was received 
from Mr. M., of Silver Bow, announcing its reappearance. 
Proceeding to Silver Bow, on May 29th, it was learned that 
the disease, so far as known, was confined to the herd of Mr. M. 
His herd had wintered in the lower Silver Bow Valley, and had 
remained free from any epizootic disease until their removal.
