 heretofore. Internal parts and organs, and particularly 

 such as receive much blood, are now more likely to fail than 

 those that are external and remote from the heart. The 

 lungs will still continue very subject to attack, because they 

 especially suffer from over-exertion ; but the brain and eyes 

 are liable at this period to fail ; the bowels likewise will now 

 experience occasional disorder from the constipations they 

 become subject to, owing to the astringent or cumulative 

 nature of the animal's food, and, as well as for want of proper 

 exercise, from the disturbances apt to be occasioned in their 

 functions by violent bodily exertion. 



This allotment of disease between the growing 

 and adult periods of a horse's lifetime will, of course, be 

 liable to vary with the regimen he is subjected to — i. e.,

 he is made to perform, and other circumstances. The view

 coupled with them be plausible or not — will appear from
