TYPICAL CASE OF CATTLE 863. 
Cattle 863 was a steer in good condition, weighing 457 pounds at 
the beginning of the experimental feeding. It was brought into the 
corrals‘on the afternoon of June 30, 1920, and received no feed before 
the experimental feeding of Z. paniculatus wascommenced. OnJuly 
3,at9 .50a.m., it wasfed leaves, stems, and young fruit of Z. panicula- 
tus, and received an- 
other feed at 5.15 p. 
_m. the same day.~ At 
9.10 a. m., July 4, it 
had eaten of the ma- 
terial 1.109 pounds 
‘per hundredweight of 
animal, and refused 
toeat more. Aft this 
time there -were- no 
definite symptoms of: 
toxic effect except the 
refusal to eat. At 
gi p.m, it was 
found much salivated 
and commenced to 
vomit. This vomiting 
continued at frequent 
intervals for about 
one hour. Plate Li, Fia. dee nemperarare Gurve of Cattle 863, 
figure 5; shows dhe 
animal in the act of vomiting. No further symptoms were noted 
except the rather unusually low temperature of 99.9° F. at 7.25 a. m., 
July 5. At this time the general appearance of the animal was pod. 
and it was turned into the pasture as practically recovered. Text 
figure 4 shows the curve of temperature, indicating a depression as in 
the other cases. 
ACCIDENTAL CASE OF HORSE 137. 
No experiments in feeding the plant to horses were made. An 
accidental case, however, occurred which was of considerable interest 
and should perhaps be recorded, since little definite evidence has ever 
been obtained regarding the pice of Zygadenus upon this class of 
animals. 
Horse 137 was one of the saddle horses used at the station. On 
July 6, 1920, at 8.15 a. m., it was noticed that this animal was much — 
depressed and salivated, and saliva scattered about the corral 
showed that this condition of salivation had continued for some time. 
While this animal was a so-called gentle horse, it never readily per-
