THE CAUSE OF TREMBLES IN CATTLE, SHEEP AND HORSES 

 AND OF MILK-SICKNESS IN PEOPLE. 



E. L. MOSELEY. 



(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 

 onlv 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 especially 

 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
