POISONOUS PROPERTIES OF THE WHORLED MILKWEED. H 
At 7.23 a. m. it was down, throwing itself about spasmodically. 
The pupils were dilated and the animal was somewhat bloated. 
Opisthotonos was pronounced. The temperature at 6.40 a. m. was 
101° F., and at 7.33 a. m. 103.4° F. At 8.02 a. m. running move- 
ments of the legs commenced. During most of the day and through- 
out the night following the condition of the animal did not change in 
any marked degree. It had mild spasms, accompanied by convulsive 
movements of the head and jaws. At times there was distinct 
trembling. Much of the time there was a good deal of bloat. Run- 
ning movements occurred at times. The pulse was weak and the 
temperature at 2.10 p. m., and at 10.15 was as high as 105° F. The 
general condition was much like a mild case of Asclepias galioides 
poisoning. At no time were the spasms of a violent character; 
generally speaking, there was some correlation between the bloating 
and the spasmodic movements. 
During the forenoon of July 23 it was more quiet than on the 
preceding day, but it still groaned, had a weak pulse, and at 9.35 
a. m. the temperature was 104° F. At noon, while the pulse was 
still rapid, it was strong. During the afternoon the sheep drank 
water and became more quiet, though it was still bloated. 
During the forenoon of July 24 the pulse varied, being weak at 
times, but on the whole showed improvement. The sheep attempted 
to eat at 9.35 a. m. It remained down until 2.30 p. m., when it got 
on its feet. 
On July 25, while still much depressed, the sheep was improving 
steadily and both ate and drank. The temperature was normal, but 
the pulse, while strong, was still rapid. By the night of July 26 
the sheep's condition was normal. It was kept under observation 
on July 27, and was turned into pasture on July 28. 
SYMPTOMS. 
Of the three sheep poisoned by Asclepias verticiTlata var. geyeri, 
two, Sheep 482 and Sheep 523, were sick, and one, Sheep 473, was very 
sick. Both Sheep 482 and Sheep 523 staggered and showed general 
weakness, which, in the case of Sheep 482, was more pronounced in 
the hind legs. In this animal the respiration was labored and in 
Sheep 523 a weak pulse was noted. 
In the case of Sheep 473 all the typical symptoms of Asclepias 
galioides were noted, including weakness, especially marked in the 
hind legs, staggering, weak and rapid pulse, labored respiration 
(the expirations accompanied with groans), dilated pupils, elevated 
temperature, bloating, spasms with opisthotonos, and running move- 
ments. Spasmodic movements of the mandibles in a chewing move- 
ment were very noticeable.
