298 DIAKKHCEA. 



In the horse we prefer a mild dose of cape aloes, but not 

 to be repeated except at long intervals. A host of astringent 

 preparations have been suggested. I here subjoin a few 

 prescriptions for diarrhoea in the different domestic ani- 

 mals. 



The following is a useful astringent for general purposes : 



Prepared chalk . . . . 1 \ oz. 



Catechu . . . . . 2 dr. 



Powdered opium . . . \ dr. 



Powdered gentian . . . 2 dr. 



Water 10 oz. 



This may be given in ale or gruel 



As a tonic astringent draught in cases of debility, and when 

 the diarrhoea seems to be due to the animal's weakness, 

 either of the following formulae may be employed for the 

 horse or ox: 



Tannic acid J dr. 



Powdered gentian . . . . 1 oz. 



Water 4 oz. 



To be given in ale or gruel; or 



Powdered angustura bark . . 1 J oz. 



Sulphuric acid 1 i oz. 



Water 24 oz. 



A wine-glassful of the above given three or four times daily 

 in water. 



Like purgatives, astringents may do harm if used in 

 excess, and this I especially find in the diarrhoea of suck- 

 ling animals. In these great benefit is derived from change 

 of diet, or giving them a little milk frequently, and at the 

 same time giving a tablespoonful of the common rennet such 

 as is used in making cheese. The white of one egg in water 

 or milk has a very desirable effect.
