gangrenous metritis with the Bacillus necrophorus present as one 
of the causative factors. The female genitilia are often infected 
by being covered with a ram with a necrotic ulcer on the penis 
or sheath. In one band where ewes were bred under these con¬ 
ditions in December, they aborted during the winter, Dr. Eakins 
has noted a lamb born with a necrotic ulcer on the head and one 
with a necrotic ulcer on the tail at three days old. 
Recently an imported ram belonging to the college became ill, 
there was loss of appetite, dull, and later accelerated respiration. 
The buck died on the third day. An autopsy was held. The 
following is the anatomical diagnosis : Ulceration of the prepuce 
and entire urethral passage, covered with a diphtheretic mem¬ 
brane. Hemorrhagic cystitis with retention of urine. Diphtheritic 
membrane of ureters and pelvis of kidneys Hemorrhagic infarct 
of left kidney. Chees^ necrotic areas up to one-fourth inch in 
diameter throughout both kidneys. Both kidneys were four to 
five times their normal size, the right one weighing 400 grams. 
The sectioned surface appeared grayish and friable. Cloudy 
swelling, inflammation and areas of necrosis. Calculi in the 
left ureter. Caseation necrosis of the deep inguinal lymph 
glands. 
Microscopic Diagnosis —The capsule of the kidney stripped 
easily, adhering only at the whitish gray areas that were super¬ 
ficial. A smear from these areas stained with Loffler’s methylene 
blue showed characteristic metachromatic granular staining 
Bacillus necrophorus, proving the case one of necrobacillosis. A 
culture was made in plain agar by shake method for anaerobic 
germs when a characteristic growth appeared. 
Sections made from the kidneys extending into the necrotic 
area showed cells in all processes from cloudy swelling to* necrosis, 
as well as acute nephritis with intense active congestion. 
This buck was purchased from a herd in Wisconsin less than 
a year previous to his death. He had not had access to ewes for 
at least four months and no cases of necrobacillosis had been 
known on the premises for two years. 
Necrobacillosis in Hogs —This beast of the devil comes in to 
pay his toll. Three years ago the writer investigated an outbreak
