vary glands, and the subcutaneous connective tissue around the 
angles of the inferior maxilla, upon its sides, in the inter-space 
between the rami and upon the neck below the base of the ear ; 
while the lymphatic glands and subcutaneous connective tissue 
of the flanks, legs, sides, and shoulders were next the most fre¬ 
quent seat of the disease ; and lastly the tongue and lungs. I 
never have witnessed a case in which the abdominal organs 
were affected; but find such recorded by Drs. Salmon and 
Smith on page 410 of the Special Report on Diseases of Cattle 
and Cattle Feeding issued by the Bureau of Animal Industry, 
1892. 
From the authorities of other countries we learn that the 
seat of the disease is not the same in all districts. In Germany, 
for instance, the tongue and pharynx are the seat of these acti¬ 
nomycotic new formations. In England as in some parts of 
this country where the conditions are very similar, we find them 
about equally divided between the internal and external struc¬ 
tures about the head ; while in some parts of this country where 
the conditions are different we find that the pathological 
growths predominate in the external forms. To illustrate, on 
the northern ranges in Idaho, Wyoming, Montana, and North 
Dakota, there are but few, and those principally of the osseous 
type. The inferior maxillae being most frequently the seat of 
the transforming growth. In Illinois, Iowa, Minnesota, Mis¬ 
souri, eastern Kansas and Nebraska and southeastern South 
Dakota the disease is principally located in the superficial gland 
structure and subcutaneous connective tissues. In Germany 
and parts of- England and America the tongue is most fre¬ 
quently affected. The reason for this variation I think has been 
largely overlooked. In this country many stock men attribute 
the trouble to dehorning, others to stagnant water, while still 
another class admit that they know little of it except tnat oi 
late years the cases seem to be more numerous. 
In Europe Veterinarians recognize the true cause and gen¬ 
erally attribute its source to forage grown on lands that are 
frequently flooded, and especialy to the use of straw for foiage,
