five affected steers were put on dry feed and in a week or ten 
days showed improvement. Later on they were turned to the 
blue grass and the symptoms returned in a severe form. On 
March 23d, after having been on dry feed for about two 
weeks, the symptoms shown by these five head were not very 
marked. 
O11 this same forty acre pasture, on the 24th of December, 
1900, eighty cows and about twelve calves were placed. In three 
days as many as twenty cows and calves began to show symp¬ 
toms. This herd was immediately driven to another pasture, 
where in the course of two weeks the symptoms became unno- 
ticeable. About the 5th of March they were returned to the-forty 
acre pasture mentioned above, and on March 23d, 1901, two six- 
months-old suckling calves had violent symptoms. In these two 
cases the symptoms returned in about five days after they were 
put back into this pasture, or on the 10th of March. They per¬ 
sisted and were plainly evident until March the 23d. 
Two steers developed like symptoms on a pasture of timo¬ 
thy, clover and blue grass two miles from Mr. Arnold’s 
ranch. 
Mr. Arnold has a large flock of well-bred sheep which are 
kept on the part of his farm devoted to sheep raising. The 
ground on which they pasture is hilly and of a limestone soil. 
It is well set in blue grass and contains some wild grass. Dur¬ 
ing the winter of 1900-1901 fifteen of the yearling lambs de¬ 
veloped exactly the same symptoms as those shown by the 
cattle. The flock of sheep was driven through a gate into an 
adjoining pasture amd in two weeks all were entirely well. At 
my request, on March 23d Mr. Arnold returned eight lambs to 
the pasture where the disease originally developed among the 
sheep to await results. 
No post-mortem was held. I advised potassium bromide in 
ounce doses twice a day as a treatment for the cattle whenever 
the symptoms became alarming. Up to date I have not heard 
from the result of the treatment nor whether the lambs became 
diseased again.
