DISTRIBUTION OF THE ARTERIES, VEINS, &C. Ill 



blood-vessels, brain, nerves, viscera, &c. For this reason, and 

 in order to render assistance to those desirous of practising 

 the veterinary art, the author has thought proper to introduce 

 a description of these vessels. We are compelled from long 

 usage, and because the English language will not furnish us 

 with suitable terms to express in all cases our meaning, to 

 adopt technicalities, which at first sight may appear superflu- 

 ous and unsurmountable ; yet it has ever appeared to us that 

 this is the best system. For students we principally design 

 this part of the work : should it be deemed worthy the atten- 

 tion of the farmer and stable keeper, we shall feel amply 

 repaid for our trouble. 



To compose this part of the work, we have availed our- 

 selves of Professor Percival's lectures. The same talented au- 

 thor, in his introductory remarks, says, " The theory of medicine 

 in the human subject is the theory of medicine in the brute ; 

 it is the application of that theory — the practice alone — that 

 is different. Whether we prescribe for a man, or a horse, a dog, 

 or a cat, the laws of the animal economy are the same in all ; 

 and cue — and that an unerring system of principles, built 

 upon ascertained and established truths — is to dictate our 

 practice in all. We might as well, in reference to the princi- 

 ples of each, attempt to separate surgery from medicine, as 

 insist that either of these arts, in theory, is essentially differ- 

 ent from the veterinary : every day's experience serves to con- 

 firm this our belief, in showing us how often the disease of 

 a horse arises from the same causes as those of a man, exhibit 

 the same indications, and require a similar method of cure. 

 " To the old practitioner we would fain hint, that nothing is 

 so effectual a barrier to advancement, nothing so prejudicial 

 to the art, as to continue the use of remedies purely because 

 they were the infallibles of those who went before : let him 

 be wary how he vainly piques himself of his experience." 



An accurate examination of the interior parts of animals, 

 a studious survey of the arrangement, structure, form, con- 

 nection, use, and relation, of these parts, and of the laws 

 by which they are intended to act, as also of the nature and
