THE HORSE AXD ITS DISEASES. 51 



than a horse in proper condition and regular exercise 

 would display in a long journey, continued at the same 

 rate without intermission. These are all indications of 

 nature not to be mistaken, or denied, by those at all 

 connected or conversant with the subject before us, and 

 sufficiently demonstrate the resulting effects of continuing 

 to overload the system with a greater quantity of food, 

 than there is proportional exercise to carry off. 



Perspiration, that is the gradual emission (physically 

 termed insensible, as not being profuse to perception) 

 will, in even gentle exercise take from the superflux of 

 the blood, what the necessary evacuations of dung and 

 urine take from the accumulated contents of the intestines, 

 which if suffered to remain in an abundant and preterna- 

 tural proportion, must by its compulsive retention, 

 acquire a degi'ee of putrid or acrimonious morbidity, 

 inevitably producing disease. 



These morbid attacks act differently upon different 

 subjects, according to their state or tendency, at the time 

 of the blood or body assuming a corrupt or infectious 

 influence, displaying itself in such a way as is most 

 applicable to the constitutional predominance of disease 

 in the horse, previous to the least trait of discovery. 



Exercise in all its particulars of manner, distance, and 

 duration, must be entirely regulated by contingent reflec- 

 tions upon the health, state, and condition of the subject ; 

 so it must be perfectly clear, that the recommendation of 

 certain exercise to horses in a high state of health and 

 condition, cannot be supposed to extend to those under 

 physic, or in different states of recovery from disease. 

 Such must unavoidably receive judicious regulations from 

 the parties concerned, as the kind of daily exercise we 

 now have in contemplation, only appertains to horses in 

 health, the preservation of which is the present object of 

 consideration. All the observations under this head 

 have been introduced to demonstrate the utility of exer- 

 cise in general, and the ills that certainly arise from the 

 want of it.
