THE MEADOW DEATH CAMAS io* A POISONOUS PLANT. 
teeth, but was very much better than on the preceding day. During 
the day the general condition of the animal improved rapidly. 
At 8.45 a. m. September 9 the temperature was 103.4° F.; pulse 
108, but somewhat irregular. The weakness had disappeared, and 
except for the slight irregularity of the pulse the animal was con- 
sidered recovered. 
DISCUSSION AND RESULTS. 
SYMPTOMS OF POISONING. 
The symptoms following the feeding of the plant to the experi- 
mental animals were carefully observed and are summarized below. 
SYMPTOMS IN SHEEP. 
Salivation. — Salivation, shown by "frothing at the mouth," 
occurred in 18 of the 28 cases in sheep that showed symptoms. 
Plate II, Figure 1, shows a salivating case, sheep 611.

Nausea. — Thirteen of the sheep gave evidence of nausea, and in 
11 animals this resulted in vomiting. The nausea was accompanied 
with frequent regurgitation and with grating of the teeth in 9 cases. 
Weakness. — Sixteen of the animals exhibited muscular weakness 
shown especially in a staggering gait. In 6 animals this weakness 
was most pronounced in the hind legs. Sheep 617, while able to 
hold herself up, was down most of the time for a prolonged period. 
Sheep 639 was completely prostrated for 2 5 J hours and much of the 
time was in a condition of coma. 
Temperature. — There was a distinct lowering of the temperature in 
14 cases. Figure 2 gives the curve of temperature of sheep 642, 
showing the marked depression which occurred at the three different 
times it received the plant. It may be noted that this animal was 
severely poisoned in August and September, while in July it was 
only slightly affected. The curve of July shows a distinct depression, 
but not so marked as at the other times. 
Pulse. — It was noticed that the pulse was weak at some stages of 
the illness in 8 cases. An irregular or intermittent pulse was noted 
in 14 animals. 
Respiration. — The rate of respiration varied, but had no character- 
istic peculiarities. In one animal it was labored at one period of the 
illness.
