entire closure of the jaws. Twenty-five or even thirty- 

 grains of the farina of the nut may be given at first, and 

 one-third of the quantity first administered should be re- 

 peated every ten or twelve hours, until full purgation 

 occurs. If aloes be preferred, it will be not only more 

 convenient, but they will operate more quickly, if they be 

 given in solution. If a prejudice exists in favour of a 

 mercurial purgative, calomel may be given previously, to 

 the amount of two drachms. The powder being blown 

 into the mouth by means of a proper tube for the purpose ; 

 and in this case six or seven drachms of aloes will suffice ; 

 but without calomel ten or twelve drachms in substance 

 will not be too much for a strong, full-sized horse ; and it 

 will probably require three drachms more, repeated two or 

 three times at intervals of five or six hours, ere a complete 

 emptying of the bowels is made, such is the usually con- 

 stringed state of the intestines at these times ; laxative 

 clysters (after the back has been properly raked) must also 

 assist the attempts, and should be thrown up in large quan- 

 tities frequently repeated. We know it to be a practice 

 with some veterinarians to unite digitalis and camphor with 

 aloes, but it does not appear that any marked benefit has 

 resulted therefrom. With others, extensive vesication over 

 the spine from the poll to the tail has succeeded. 



It is certainly desirable that the bowels should be first 

 opened ; but if the irritation be extreme, and the back has 

 been raked, clysters thrown up, and an active purgative have 

 entered the stomach, we should recommend not to wait the 

 operation of purging, but to give the sedative, and then 

 renew the attempts at unlocking the bowels.
