WESTERN SNEEZE WEED AS A POISONOUS PLANT. 13 
toms, however, did not appear until September 15. At that time 
it was still eating freely of the plant, but was gradually getting 
weaker, would lie down much of the time, and, when walking, dragged 
its hind legs. On the next day (September 16) the animal was not 
only lying down much of the time, but, when attempting to walk, 
acted as though the hind legs were stiff. On September 18 the weak- 
ness had so much increased that when standing it trembled and 
found great difficulty in keeping its feet. Plate I, figure 1, shows 
the animal at 10.44 a. m. On the afternoon of September 18 it was 
lying down with head stretched out, and when put on its feet was 
unable to stand more than a minute or two at a time. On Sep- 
tember 19 the pulse was weak and the animal was down and did not 
attempt to rise. On the morning of this day it was given 3 ounces 
of Epsom salt and a subcutaneous injection of one-tenth. of a grain 
of strychnin. The pulse was noted as irregular and the respirations 
rapid. The pictures, Plate I, figures 2 and 3, were taken at 10.45 
a. m. and 10.46 a. m., and show very clearly the extreme weakness 
of the animal at this time. On September 20 it was given 1 ounce 
of Epsom salt and a subcutaneous injection of one-tenth of a grain 
of strychnin. The sheep was so weak that it was unable to raise 
the hinder part of the body from the ground. On this day the 
animal was regurgitating ; some green mucus ran from its mouth 
and nostrils, but it did not vomit. On September 21 it appeared 
somewhat better, perhaps as the result of the action of the Epsom 
salt, and on this day it was given two doses of one-tenth of a grain 
of strychnin. The sheep was given alfalfa hay and bran and this 
feeding of hay was continued on the succeeding days. On Septem- 
ber 24 the animal received 2 ounces of Epsom salt, and on September 
25 appeared very much stronger. From this time there was a con- 
tinual gain in the sheep's condition, and on September 28 it was 
turned out into the pasture. On September 30, the last day of 
observation, the animal weighed 103 pounds. It was evident, how- 
ever, that recovery at this time was only partial, for the animal's 
general condition was rather bad. 
Typical Case of Sheep 380. 
Sheep 380 may be taken as a type of those animals subjected to pro- 
longed feeding which, in addition to weakness, showed a pronounced 
tendency to vomit. The animal, a ewe weighing 60 pounds, was 
brought to the station May 28, 1916. The feeding was commenced 
on May 30 and was continued until July 2,1, 53 days. During 
that time the animal ate 113.82 pounds of H. hoopesii. Symptoms 
of poisoning, however, appeared in 25 days from the commencement 
of the feeding, at which time the animal had eaten 64.583 pounds.
