DISEASES AND TREATMENT.

worse in cold stormy weather. He was advised to clean up the 
yard, sprinkle lime around the correll and on the stable floors. 
Disinfect with creolin or carbolic acid, 5 per cent. Isolate the 
well ones from the sick calves and swab out the sores with a 1 
per cent, permanganate of potash or the same strength of creolin. 
All buckets for serving drink should be separate for the sick 
calves. 
Nor does necrobacillosis in cattle stop at this point. There is 
an excellent specimen in the museum of Colorado Agricultural 
College of a liver of a beef thoroughly permeated with necrotic 
areas teeming with the Bacillus necrophorus. 
Necrobacillosis of Sheep —Sheep and particularity lambs first 
placed in the feed lots are subject to wounds of the lips due to the 
hard alfalfa, Russian thistle, etc. Those placed on beet pulp and 
other feed soft in nature do not contract sore lip. In these 
wounds pus germs, principally the streptococci and staphylococci, 
aureus and albus, gain entrance, later the ubiquitous Bacillus 
necrophorus enters, finds conditions favorable by this symbiosis 
and produces a deep slough, cup shaped and containing a cheesy 
necrotic material. These lesions emit the characteristic odor and 
from them the Bacillus necrophorus can be isolated. In the sheep 
placed in the feed lots of Arizona, New Mexico and Colorado the 
organism finding its way into the wounds is of a strain with 
low virulency and the sheep recover or gain an immunity in from 
three to four weeks without treatment. According to statistics 
gathered by the writer in this investigation work; it appears that 
this disease has existed in this region, and about the same viru¬ 
lency, for at least thirty years. In Wyoming the Bacillus necro¬ 
phorus is of a more virulent strain and attacks the legs, sheath 
and other genitilia. Its recovery does not take place spontan¬ 
eously, but yields readily to hot creolin or similar antiseptic. 
During the past winter and spring some interesting observa¬ 
tions have been made by Dr. H. S. Eakins, secretary of the 
Wyoming Sheep Inspection Board. 
Ewes having trouble lambing are sometimes assisted by the 
sheep herder who inserts the hand. Often these cases die of
