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 feeding was 

 undertaken, on July 1. 



On July 1, at 11.15 a. m., the animal was given by balling gun 

 1.764 pounds, per 100 pounds of animal, of leaves, stems, and young 

 fruit of Z. paniculatus. At 2.30 p. m. the animal was frothing 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- 

 ceding evening. 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 pulse and respiration, the changes were 

 not significant. 



Sheep 602 may be considered as a fair t3'pe of animals which are 

 not ver} r sick. 



TYPICAL CASE OF SHEEP 509. 



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. panicidatus. At 4.37 p. m., the animal .
