this species as hay in any appreciable amounts. They took in-
creasing amounts as the trials progressed. The last hay palatab-
ility trial terminated on December 27, 1932. A decreased appe-
tite was evident in these three animals shortly prior to that date,
and total loss of appetite occurred soon. Blood was passed in the
feces, and some nasal hemorrhage occurred. The animals died
on January 7, 18, and 20 respectively.

 The autopsy findings of Thomas, Shealy and Ahmann* were
 as follows:
 "All mesenteric and body fat, the pericardium, gallbladder,
 and mucosa of the small intestines showed petechial hemorrhag-
 es. Ecchymoses were noted in the anterior portion of the front-
 al sinus, mucosa of the trachea, small intestines, and bladder.
 Blood clots were observed in the posterior part of the frontal
 sinus. The heart showed endocarditis, myocarditis and pericar-
 ditis. The liver was finely mottled, red and maroon. The spleen
 was slightly enlarged. Edema occurred in the wall of the abo-
 masum. The large intestines contained an abundance of clotted
 blood. The brain was congested with gelatinous material in the
 sulci. The lymph nodes were slightly congested."
