SYMPTOMS AND REMEDIES 275 



rib. There is no danger at all in this operation and it 

 should be done promptly on account of the rapid pro- 

 gress of trouble. Sometimes the hole may be opened 

 to about four or five inches in length and a portion of 

 the contents of the stomach pulled out by hand. This, 

 however, is seldom necessary, as, the pressure of the 

 gas being removed, the ordinary operation of the 

 stomach will soon clear out the mass of green feed 

 to which the trouble is due.

 Weed of the Plains' by Prof. C. D. Marsh : 



1. Some locoed animals will recover if taken from 

 the weed and fed well without any treatment. 



2. Most locoed animals will recover if they are taken 

 from loco, fed carefully and treated on the lines indi-

3. In all cases care should be taken to relieve con- 

 stipation, either through the character of the food or 

 by use of magnesium sulphate. 



4. Horses are best treated with Fowler's solution 

 in daily doses of 15 cubic centimeters continued for 

 at least a month. 



5. Cattle are best treated with daily doses of strych- 

 nine, not exceeding three-twentieths of a grain, given 

 hypodermically and continued for one or two months. 

 It is especially important that the dose should be small, 

 as locoed animals are very susceptible to the bad effects 

 of over-dosing. 



This then should be borne in mind : Use Fowler's 



solution of arsenic for horses, and strychnine for cattle. 



To those who desire to study the matter more care-
