THE WOOLLY-POD MILKWEED. 5 
— On July 16, at 6.45 a. m., the animal was distinctly depressed. — 
The depression continued throughout the day. During the day, too, 
the temperature fell, reaching 100.20° F. in’ the morning and being 
~ much below normal during the day, as shown in the curve, Fi igure 6. 
_ At that time also the pulse and respiration were considerably more 
: rapid than normal. At times during the day the animal groaned 
and the respiration was more or less labored. ‘These symptoms con- 
tinued on July 17, the respiration being more labored and the pulse 
a and weak. 
From the morning of July 17 to July 18 she was kept in the metab- 
olism cage for collection of urine. During July 17 there was a 
marked increase in temperature, rising to 104.9° F. This was a jump 
_ from the low temperature of 100.4° F. of the preceding day. 
July 18. In addition to the symptoms noted on the preceding days, 
. the feces were liquid and contained much mucus, and there was a 
_ heavy mucous secretion from the nose. The sheep was weak and lay 
_ down most of the time. 
_ July 19. In the morning the feces were found to contain not only 
“mucus but some blood. The animal would stand only when urged 
_ to do so. Up to that time the animal had eaten nothing since the 
_ definite symptoms appeared. She was strong enough to keep on her 
_ feet, but did not stand voluntarily. 
July 20. The feces continued of the same character and had a very 
offensive odor. There was some trembling of the head, neck, and 
- flanks, and the animal was weaker than on the preceding day. 
July 21. While the general symptoms continued as before, the 
animal seemed less depressed and in somewhat better condition. 
There was a drop in temperature from the preceding days, more 
nearly approaching normal. 
July 22. The improvement in the general condition continued and 
_when turned into the pasture in the morning she commenced to feed. 
_ The feces were less liquid than during the acute time of the sickness, 
and the animal seemed fairly strong, although distinctly “ gaunted.” 
_ During the day she apparently continued to ‘feed and was able to get 
~ about fairly well. 
3 July 23. She was again turned into the pasture with the other 
animals and continued with them. 
July 25. It was noted that she had gained in weight and had made 
-yery marked improvement, the depression having almost entirely 
July 29. She was found dead, having been caught between two 
5 trees. Presumably she was too weak to extricate herself. Had it not 
Ps been for this accident she probably would have recovered completely. 
The autopsy was made in the morning, the noticeable lesions being 
the congested lungs and duodenum. The spleen was soft and the 
E: gail bladder was distended with gas, the bile being somewhat thick- 
ened. As the animal had been ‘dead for some time, some of the 
_ changes in tissue may have been due to post-mortem effects. 
: The photographs for Figures 2. 3, 4, and 5 were taken on July 19 
and show very clearly the “depr essed and weakened condition of the 
animal.
