A CONTRIBUTION 
TO THE PATHOLOGY AND AETIOLOGY OF HUMAN AND ANIMAL 
VARIOLA. 
Translated by F. S. BILLINGS.

-:o:- 
The complications to which v. vaccina is liable are rather 
numerous. The normal development of the variolse is very fre¬ 
quently interrupted by milking, by the animal itself in lying 
down, by licking the parts in question, by the contact of the com¬ 
plicated udder with the animal refuse on the stable floor, and by 
the latter itself ; the variolse are disturbed, suppurating ulcers be¬ 
come developed, haemorrhages are frequently present; the devel¬ 
opment of eschars is retarded, and sometimes long continued 
profoundly irritating ulcerations are present upon the teats. Aside 
from this the grade of local inflammation upon the udder or teats, 
as well as the sensitiveness by milking, is chiefly conditioned by 
the number of pustules.
