REPORTS OF CASES

rounded ends, and about three millimetres in length. The 
same specimen, under a one-sixth objective with one-inch eye¬ 
piece, showed the same bacillus in the form of numerous bead¬ 
like cells, enclosed in one common sheath. No means were 
at hand for cultivating. 
Remarks. —All of the animals affected have been out of 
doors on the ranges all the' winter, and while they were not 
poor, yet their systems were in a debilitated, depleted 
condition in the spring. During May and the early part of 
June we have had an abundance of rain for this climate, which 
has brought up a luxuriant growth of grass on the pastures; 
and these horses, while not in high condition, were thriving 
and gaining quite rapidly. Only a small portion of the land 
is low, most of it being high, rolling prairie, some of it hilly, 
and all with a sandy, porous soil. The water supply is pure 
on these pastures. The altitude here is about six thousand 
feet. These animals died in three pastures about five or six 
miles apart, and all at about the same time, from June 15 to 
July 1st. No deaths have occurred since July 1st. 
No disease has been known on these pastures in the past, 
though both places have been used for years for cattle. In 
one case, cattle were removed and horses turned in there 
about a year and a half ago ; in another, horses have never been 
ranged there until this spring. 
All of these dead bodies have either been burned or buried, 
and in all but one instance the horses removed to another 
pasture. 
I report these cases, with this much of detail, hoping that 
by so doing we may gain some knowledge of the cause, what 
this disease is. Reasoning from the symptoms, and post-mor¬ 
tem appearances, with the history of the cases, we have called 
it anthrax. I have no record of anthrax in horses having ex¬ 
isted in this section.
