muzzling was adopted, and the number of cases fell to 129 in 
1890, 79 in 1891, and 38 in 1892. Then, owing to persistent 
opposition, muzzling was stopped, and the effect of withdrawing 
this measure was at once seen in the increase of rabies. In 
1893 there were 93 cases, in 1894, 248, and in 1895, 672. At 
this point, owing to public alarm, muzzling was again enforced, 
reducing the number of cases in 1896 to 438, in 1897 to I5i,in 
1898 to 17, in 1899 to 9. As no case was discovered from 
Nov., 1899, to March, 1900, it was believed by the veterinary 
officer that the disease had been extinguished in Great Britain. 
No stronger evidence in favor of muzzling could be asked 
for or desired than this complete success in an extensive and 
thickly populated country like Great Britain. 
A BACILLUS FROM AN INFECTIOUS VULVAR DISEASE 
OF CATTLE. 
By Joseph W. Parker, D.V.S., St. Joseph, Mo. 
Read before the Missouri Veterinary Medical Association, at St. Louis, Oct. 3, 1900. 
Under the title “ A Cattle Disease in Marshall County, 
Kansas” (see Fifteenth Annual Report of the Bureau of Ani¬ 
mal Industry, U. S. Department of Agriculture), an apparently 
contagious pustular disease, with localization chiefly on the 
vulvse of cows and heifers, is described (February, 1898) by Dr. 
Rice P. Steddom, an Inspector in the Bureau. In this out¬ 
break only females were affected, and the disease certainly was 
not communicated by copulation. Usually after the bursting 
of the pustules the resulting ulcer had a tendency to slough 
extensively, discharging a sanious fluid. The contagious ele¬ 
ment and the mode of communication were not determined. 
In the fall of 1899 an outbreak of a disease similar in charac¬ 
ter occurred near Westmoreland, Kansas. . Both cows and 
steers were affected, on the latter the ulcers being located above 
the ischial tuberosities, being similar to the ulcerations on the 
females. In both outbreaks the disease yielded readily to treat¬ 
ment (silver nitrate, antiseptics).
