no tendency to heal and frequently end in death. 
Treatment .? 
Treatment consists in the local application of antiseptics to 
the ulcers. Each animal of an infected flock must be caught, the 
ulcers exposed, the cheesy mass raked off to expose the raw sur¬ 
face, and the surface liberally swabbed with some good antiseptic.

Tincture of iodine and Lugol’s solution of iodine have been used 
with excellent results. Five per cent carbolic acid is highly recom¬ 
mended as well as of creolin. Three per cent potassium perman¬ 
ganate is good. To get the best results the animals must be treated 
daily for about a week. Dipping did not prove as satisfactory as 
the hand dressing and is not now much used. 
BACILLUS NECROPHOROUS IN OTHER CONDITIONS. 
This organism has been found in a large variety of diseased 
conditions in animals, such as Foot Rot of cattle and sheep, Quittor 
and Scratches in horses, Necrotic Anovulvitis in cattle, and in fact 
as a secondary invader in many wounds. No matter where found 
it always has the distinctive odor and is easily destroyed if it can 
be brought into contact either with air or antiseptics. Just why it 
assumes more virulent form in our Western States, we do not know, 
but such seems to be the case.
