" diseases of the digestive organs," &c. This method of classification. 

 'hough not without its advantages, and though it would seem, at first view, 

 to present an arrangement most convenient for reference, examination and 

 comparison, in the end, leads, I think, to confusion and misunderstanding 



ANATOMY OF THE SHEEP. 



He who breeds sheep to any considerable extent, should make himself 

 familiar with the anatomical structure of some of the paits of the animal^ — • 

 paiticuhirly with the arrangement, size, natural appearance, consistency 

 and contents of the several viscera ; to some extent with the circulatory 

 system; with the alimentary and respiratory organs ; with the brain, and 

 the whole osseous structure of the head. He should be in the constant 

 habit of making more or less extended examinations of all these structures, 

 as opportunity occurs l)y the slaughter of sheep for economic purposes; 

 and when the animal dies from disease, such examination should be in no 

 ordinary case omitted by the flock-master who is desirous of making him 

 self tliorov gill y acquainted with his business. He will require some instruc 

 tion, in the outset, to enable him to make suc^i dissections understandingly 

 and properly ; but he can readily obtain this from any educated physician 

 or surgeon. There are no sufficiently wide differences in the anatomical 

 structure of the sheep and of the human being, to give the surgeon the 

 least difficulty in pointing out the airangement, uses, &c., of the several 

 parts of the former, unless it be in the conformation of the stomachs. — 

 Here, the structure of the sheep, like that of other ruminating animals, dif- 

 fers widely from man, l)ut that physician or surgeon must have been singu- 

 larly limited in his physiological investigations, who has not made himself 

 acquainted with it. At all events, a glance at a veterinary work, while 

 conducting a dissection, will enable him to understand, and explain it to 

 the learner. The learner while making his exammations in company with, 

 and under the direction of the surgeon, should jyerform, eiwry manipulation : 

 his own hand should handle, remove, test the consistency, &c. of the part?- 

 — alone wield the saw and guide the scalpel. This is an important rule i^' 

 he vvuuld understand and rcm,cmf>er. 



The subjects of a portion of the examinations should be sheep killed i.i: 

 full health. It is necessary to be familiar with the healthy appearance of 

 all the parts, so as to distinctly recognize all departures from it — the eflect' 

 of any diseased or abnormal action. 



The sides of a lean sheep are more tianslucent, after being skinned, than 

 those of a fat one, and therefore the former makes a better subject, if the 

 circulatory system is to be examined. On the sides of the thorax and ab- 

 domen, at a little distance from the spine, the veins and arteries of tho8» 

 parts can often be traced with beautiful distinctness, without any dissectioni 

 of the intercf)Stal muscles. 



Subjects should be examined which have had their blood drawn (by Wav- 

 ing their throats cut), and also those which have died with all theirblood 

 in them. Some of the viscera — c. g. the lungs, veins and arteries — will 

 present very different ajipearances under these different circumstances; 

 and this fact not understood might frequently lead to very erroneous con- 

 clusions in post mortem examinations. 



I will give a very general description of the parts I have mentioned as- 

 necessary to be studied — designed merely for those who have no previous- 

 krowledge of the subject. 



After the animal has been neatly skinned, plac<? it on a low table, an as* 

 •istant graspiiig its fore-legs, and holding it fimly on its back. THien slh
