the feed had been eaten. The animal was kept under observation 
during the rest of the day and showed nothing abnormal. When 
offered hay at 5 p. m. she ate it with considerable eagerness. 
September 19. — At 6.30 a. m. she was found lying down and had 
vomited during the night. At 8.45 a. m. the temperature was 
100.7° F., the pulse 44 but very weak and irregular, and the respira- 
tion 16, of a normal character. The animal could get upon her feet 
at this time, but was very uncertain in her movements. She had 
been vomiting since the preceding observation at 6.30. At 11.30 
a. m. the animal was found lying down but after some effort got 
upon her feet. She staggered when walking and when hurried 
very nearly fell. Plate II, Figure 3, shows very clearly this condi- 
tion of weakness. She had not, however, at this time lost all her 
appetite for hay. During the rest of the day she continued in much 
the same condition, although late in the afternoon she was unable 
to get upon her feet. At 8.45 p. m. she was found on her feet and 
ate, although she appeared to be much depressed. 
September 20. — At 8.40 a. m. the temperature was 98.2° F., pulse 
48, respiration 20. The pulse was regular but weak. During the 
observation she was lying down and showed no desire to get upon 
her feet. After some forcing she got up, but had very little control 
of her legs. Between 10 and 1 1 a. m. she seemed much improved and 
could walk, although the movements were stiff and weak, with some 
staggering. Plate II, Figure 4, taken at 10 a. m., shows the animal 
upon her feet, but her weakness is indicated in the position of the 
hind legs, which are braced rather far apart. There was no great 
change during the day. In the observation taken at 5.05 p. m., the 
pulse was still weak but was regular. 
September 21. — At 8.50 a. m. the pulse was still weak and the 
animal in walking showed a little weakness. She gained in strength, 
however, during the day, and in the observation at 4.10 p. m. the 
pulse was strong, regular, and normal. 
On the morning of September 22 the animal was practically 
recovered and was turned into the pasture. 
The symptoms exhibited were for the most part typical but it 
should perhaps be noted that in this animal there was no distinct 
lowering of the temperature. 
RESULTS OF EXPERIMENTAL WORK AND CONCLUSIONS 
SYMPTOMS 
Salivation. — Salivation is very nearly a universal symptom of the 
poisoned animals. This was noted in 3 of the 7 experimental cattle 
and in all but 2 of the experimental sheep. In most cases, this is 
the first evidence of intoxication. 
Nausea. — Nausea is almost invariably present and is frequently 
accompanied by vomiting. Vomiting was exhibited in all the cattle 
but in only two of the experimental sheep. In many cases the 
vomiting occurs not only once but repeatedly. 
Depression and weakness. — In mild cases the animals show only 
depression. When the illness is more pronounced it is accompanied 
by weakness which is especially noticeable in the hind legs; in the more 
severe cases the animals stagger when attempting to walk and may 
sometimes be unable to rise. Plate II illustrates tins condition in
