150 ON PHYSIC. 



from a course of them, as from a moderate dose of 

 physic. But I cannot refrain from again remarking, 

 that such horses, unless labouring under disease, would 

 be far better without being purged. I have here no- 

 ticed the classing of horses, only with regard to their 

 constitutions, and how physic may be expected to ope- 

 rate on each horse, according to the quantity of aloes 

 given. The classification of horses in their work, will 

 depend on the age, shape, and make of each horse, 

 individually ; for it is the structure of animals which 

 principally constitutes their physical powers; and it is 

 from the different points, such as the length, the depths 

 and breadth of certain parts of a race-horse, that a 

 training groom is guided in his opinion, with regard 

 to the speed or stoutness of the different horses he is 

 beginning to train, and which particular points in race- 

 horses, I can better describe when I am on the subject 

 of training. 



I hope it will be considered by my readers, that I 

 have been sufficiently explicit, as to the general prac- 

 tice of physicking race-horses, according as their diffe- 

 rent constitutions may vary. But as to all the various 

 precise periods of giving physic to different horses 

 when in training, or at other times on the road when 

 travelling, this part of the subject will be fully ex- 

 plained in its proper place. 



I shall here give a list of medicines ; and a table of 

 the weights and measures used in the compounding of 

 them. I shall also mention such apparatus as are ne- 

 cessary thereto ; as well as such other things as may
