TYPICAL CASE OF SHEEP 602. 
Sheep 602 was a yearling ewe, weighing at the time of the experi- 
ment 71.5 pounds. It was taken into the corrals on June 29, 1920, 
and kept under observation until the experimental Seeing was 
undertaken, on July 1. 
On July 1, at 11.15 a. m., the animal was given by balling gun 
1.764 sane. per 100 Sani of animal, of leaves, stems, and young 
fruit of Z. paniculatus. At 2.30 p. m. the animal was otras at the 
mouth, and in walking reeled from side to side. At 2.35 p. m. the 
weakness was most pronounced in the hind legs. This weakness gradu- 
ally increased and at 7.40 p. m. the animal, in walking, not only stag- 
gered but dragged the 
-hind.feet. The con- 
_ dition remained the 
same during the even- 
ing. The next day, 
July 2, at 6.38 a. m., 
the animal was still 
frothing at the mouth 
and apparently some- 
what nauseated, 
although it seemed 
somewhat stronger 
than during the pre- 
cedingevening. Dur- 
ing the day its con- 
dition did not change 
materially. - It was 
quiet and depressed — 
and weak, but not very sick. The last observation of the day was 
made at 4.15 p, m. 
On the morning of July 3 the animal seemed to be entirely recov- 
ered. The temperature curve is shown in text figure 2. While 
’ there were variations in the pul and respiration, the changes were 
not significant. 
Sheep 602 may be considered as a fair type of animals which are 
not very sick. '

vee LCA; CASE OF SHEEP 569. 
Sheep 569 was a 2-year-old wether, weighing 85.5 pounds at the 
time of the experiment. It was taken from the pasture into the 
corrals on the morning of July 8, 1920.. At this time the temper- 
ature was 103° F., pulse 88, respiration 32. The sheep was observed 
again at night, and on the morning of July 9. At 9.35 a. m., July 9, 
the temperature was 103° F., pulse 96, respiration 24. At 2 p- m. 
the animal was given by balling gun 0.661 pound, per hundredweight 
of animal, of fruit heads of Z. Pepa abies: At 4.37 p. m., the animal
