Remark. — Nos. 1. and 2. are absorbent and stomachic, and 

 may either be given in a little gruel, water, or beer, as a drench, 

 or made into a ball with treacle. Should there be no con- 

 venience for giving either of these, the horse would probably 

 swallow them with his food or water, especially if the bitter 

 powders were omitted. 



No. 3. is a gentle purgative, as well as absorbent and stomacBlc, 

 and is that which should be preferred when a horse can be 

 spared from his work for a day or two. The receipts Nos. 1. and 

 2. may be repeated daily as long as it is necessary ; and at an in- 

 terval of a week or ten days the purgative may be repeated.

 Terra Japonica, or Japan Earth, and Catechu, or more properly 

 Extract of Qatechu, is obtained from the inner dark-coloured 

 wood of an Acacia tree, "which grows plentifully in the mountains 

 of Kankana, in Hindostan, and flowers in June. The wood is 

 boiled in watei', and, when strained off and boiled down to one- 

 third part, is set in a place to cool for one day, and afterwards 

 the evaporation is completed by the heat of the sun. There are 

 two varieties of this extract; one brought from Bengal, the 

 other from Bombay. The latter kind is of a pale reddish-brown 

 colour, and is generally in small square cakes ; the other is in 

 round masses, of a deep chocolate colour internally, with the 

 hue of rusty iron on the outside ; it is heavier than the pale, its 

 specific gravity, being generally about 1-39, possesses more

 powerful astringent, and is given in obstinate diarrhoea, as the 

 scouring of cattle, and in diabetes, or excessive staling. I have
