THE CAUSE OF TREMBLES IN CATTLE, SHEEP AND HORSES 
AND OF MILK-SICKNESS IN PEOPLE. 
E. L. Moselev. 
(Continued from p. 470.) 
No. 4. A tom-cat weighing 5 lbs., 10 ounces. Had been 
liable to fits of coughing and vomiting, when fed meat. He 
made a poor subject. I gave him milk in which stems without 
leaves had been soaked, and after two days milk in which leaves 
had been soaked. He soon contracted diarrhoea which prob- 
ably prevented much of the poison being absorbed into the 
blood. After four days he would not take any more poisoned 
milk. He was watched a good deal but was seen to tremble 
only a few times and then under conditions which might possibly 
have produced trembling without the aid of any poison. How- 
ever, single tremors were noticed a number of times, two or 
three times a paw or foot when raised or stretched out by him- 
self was seen to tremble. Occasionally the head trembled a 
little. A slight trembling of the ears and tail continued for a 
considerable time and most persistent of all a motion of the 
loins. This is the part in which trembling is said to be most 
noticeable in cattle. Respirations at one time 35 per minute. 
When he would take no more poisoned milk I gave him a leg 
of rabbit No. 6. The next day while he was drinking cold milk 
I noticed strong trembling. Earlier in the day he had eaten 
greedily another leg and side of the rabbit. The next day, 
when held up by the nape his hind legs trembled and when put 
down he trembled all over. The meat seemed to affect him 
more than the milk. He ate readily all that was given and if I 
had had enough of it, would probably have been killed by it. 
As it was, he shared the fate of No. 2 and post-mortem exam- 
ination at the same time showed nothing more. 
Dog. 
No. 5. A small cur, was given, Nov. 25, at 8:15 A. M., milk 
mixed with a water extract of snake-root and at 1 1 :45 the leaves 
and tops of several herbs broken up and mixed with hash, also a 
chicken’s liver dipped in the extract. No effect was noticed 
that day but at 3:30 the next morning Mr. Reinheimer says the 
dog shook hard all over so that he thought it was dying. At 
10:10 A. M., as it lay on its side in the sun, it stretched out its 
legs as if yawning and trembled in a very unnatural manner. 
After dinner also we noticed some trembling of the legs especiallv 
when he changed his position. He showed some weakness, 
dullness and less disposition to bark than usual at sounds. 
Nevertheless, he was not so different from usual except in the
