ward. The results of chemical examination of a syrup made 
in the same way, I will speak of further on. 
During the first week in September, I spent a few days at 
Mr. Givens’ repeating the experiments of President Ingersoll. 
The animals that I had to examine were not so badly locoed 
as many of the flock had been, and most of them had begun 
to recover. I noticed a condition of things almost identical 
with those that are described in the President’s report. Upon 
making post mortem examinations, I found the following 
conditions : Organs of thorax were normal. In the abdom¬ 
inal cavity, I found the stomach filled with a mass of semi- 
digested loco leaves. The liver was normal in appearance ; 
gall bladder filled with a greenish color bile. In the duct, 
running from the gall bladder to the small intestines, I found 
a mass of tape worms (tcenia expansa). The small intestine 
I found filled with a mass of these worms, varying in 
length from six inches to five or six feet. The kidneys were 
normal in size and color, but, upon section I found the pelvis 
filled with a gelatinous material {amyloid de^eneratioii) . The 
muscular system was exceedingly flabby and pale in color. 
The body seemed to be absolutely destitute of fat. The 
urine was normal. The brain showed a slight, serous effusion 
about the base, and to a slightly greater extent in the region 
of the medulla oblongata. There also was a slight effusion 
into the abdominal cavity. The only other change that could 
be found in the brain of these sheep was a slight con¬ 
gestion of the arachnoid membrane. About the middle of 
October, I received a letter stating that, if I so desired, I 
could obtain some fine specimens of locoed horses, on the 
ranch of Mr. J. T. Cheatham, at Lake station, on the Kansas 
Pacific railroad, about one hundred miles southeast of Denver. 
I arrived at Lake, Oct. igth, and at once began my investiga¬ 
tion. I found several affected horses. Two of these I killed 
by bleeding, and made careful post mortem examinations upon 
them. I found the two cases exactly similar, a description of 
one answering perfectly for the other. 
“ The first case examined was a sorrel gelding that had 
been brought through from Texas. He presented the follow¬ 
ing conditions ; Great emaciation; the horse was found 
standing apart from the rest, and could not be observed to 
be eating, to any appreciable degree ; bowels extremely con¬ 
stipated. The animal apparently had lost all muscular con¬ 
trol. Whenever he moved it was in an irregular manner, as 
if he were intoxicated, and frequently he knuckled over at the 
fetlocks, as if from complete exhaustion. When a motion was 
made at him, he would throw his head upward, and stagger
