DISTOMA IN LIVERS AND LUNGS OF CATTLE.

had the characteristic rotten appearance, and the gal] ducts were 
enormously thickened and enlarged. In cysts of the latter and 
in the mass, apparently, of the liver, were the flukes. 
The third case was affected in the lungs only. The right lung- 
had one large fist-sized tumor ; the left two, located near the mid¬ 
dle of the mass. These tumors were composed of smaller cysts 
in which were the flukes, calcified masses, and a brownish 
fluid. Two other animals of the lot had livers containing vel- 
lowisli, cheesy masses, about the size of a hazel nut, scattered 
throughout their substance; whether these masses were caused 
by the distoma is uncertain. I could discover no differences be¬ 
tween the flukes from the liver and lungs further than that those 
from the latter were smaller and lighter in color. I accordingly 
have classified them as one species. 
In an old scrap-book, associated with other articles taken from 
the New York Tribune of 1870-’71, I find one by Joseph H. 
Batty recording the finding of liver flukes in the Virginian deer. 
The species is undetermined, but closely resembles D. hepaticum, 
which it probably was. 
In the June number of the Veterinary Review of 1882, on 
page 100, Dr. A. J. Murray describes distoma as infecting the 
lungs of three out of nine Texan cattle examined in one of the 
Detroit slaughter houses. He quite accurately describes all of 
the lesions which mav be found, and he was the first to record 
their discovery in this country. If every discovery of the fluke 
in this country were recorded, we could soon have data to base a 
knowledge of its distribution on, and could thus arrive at some 
just estimation of the damage caused by them. 
The presence of distoma in the lungs of cattle has been 
known in Europe since 1869, at least, and has been recorded at 
intervals as follows : 
Rivolta records it, in 1869, in Italy. Bull. Soc. Centrale de 
France , 1881, p. 68.
