H. A. Winters who had lost many sheep and other animals from 

 trembles. On returning I saw a little trembling of the flesh at 

 the hips. After watching her awhile they both felt sure that 

 she had the trembles and in conversation with me the next day 

 Mr. Winters said the symptoms were unmistakable. She ate 

 some bran while lying down, stopping to let her head rest on 

 the corner of the box. She raised her hind quarters but failed 

 in attempting to straighten her front legs and so ate while 

 kneeling. At 10 P. M. she was lying still, her respirations rather 

 deep and about 16 per minute. She gave no heed to the lantern. 



The next morning she was unable to rise or even to stand 

 when lifted onto her feet. Nor would she eat. Breathing spas- 

 modic but no trembling. At noon she was still lying in the 

 same place, her breathing deeper and about 25 per minute. 

 Without any urging she struggled as if to rise and this doubtless 

 increased the respirations somewhat. Whether she had done 

 this at frequent intervals I could not tell. No trembling but the 

 breathing quite laborious and unnatural. At 3:40 P. M. still in 

 same position. Respirations labored, irregular, 33 per minute 

 after a fit of kicking, then after a short interval 30 per minute. 

 About 4:20 there was violent struggling involving not only the 

 legs but the abdominal and other body muscles. At 4:40 I 

 found her dead. Post mortem examination the next morning 

 showed that the kidneys were enlarged to double the normal 

 size. One of them weighed 50.3 grams, one obtained from a 

 lamb of about the same size at a market and another from a 

 lamb about half again as heavy weighing 25.5 and 26 grams. 



No other organs were found enlarged, inflamed or con- 

 gested or in any way unnatural in appearance with the possible 

 exception of the brain which some thought slightly congested. 

 The abdominal cavity contained several ounces of liquid, "due 

 to feeble circulation preceding death." Besides H. C. Schoepfle, 

 M. D., and Dr. Hinkley, a veterinary physician, I had three 

 butchers, one at a time, examine the body. There had been no 

 constipation. The rumen was well fllled with snake-root. 

 Death would likely have come almost as soon had she eaten none 

 of it after Sunday. The quantity given Saturday afternoon and 

 Sunday was 42 ounces, of which 14 may have been eaten. Likely 

 enough a small fraction of this would have sufficed to produce 

 trembles, though death might not have come so quickly — four 

 days from the time of first feeding. 



Meat from this sheep was fed to four animals. A large cat 

 ate six ounces of the liver about 5 P. M. and the next morning 

 trembled violently, less as the day went on and, after that, none. 

 A cat of the same size ate six ounces of muscle from a hind leg, 

 but showed no effect for two days or so when it became sick, 

 losing its appetite but not trembling. It has recovered. A
