conjunctive, gives the grey appearance to the white of the eye. The 

 membrana nictitans is extremely small, being about a line in length 

 and breadth. At the back part of the cavity of the eye there is a little 

 light-coloured pigment. 



" The black skin covering the end of the nose is remarkably lax, 

 and the muscles going to it are well developed : its motions are said 

 to be very free. 



" Among the peculiarities of the muscular system the most remark- 

 able is a blending together of the obliqui externi and recti abdominis 

 muscles, so that the origin of the latter partook of the character of 

 the insertion of the mesial pillars of the abdominal rings ; the left rec- 

 tus arising thick andtieshyfrom the right o«p?t6is,and passing through a 

 large slit in the origin of the right, which arose in a corresponding man- 

 ner from i\\Qospubis of the left side : as there was no tendon covering 

 these fleshy columns, it was doubtful at first whether to consider them 

 as fleshy insertions of the external oblique, or decussated origins of the 

 rectus: the latter muscles are however evidently distinct from the ex- 

 ternal oblique at the epigastric region of the abdomen, and pass over 

 the cartilages of the true ribs to be inserted into the upper part of the 

 sternum, and have no other attachment to the pubis but through the 

 medium of the fibres before described. The external oblique muscles 

 had the usual serrated origins from the ribs, the allantal fibres pass- 

 ing obliquely downwards, and blending with those of the recti, the 

 lower fibres being inserted distinctly into the rami of the pubis, and 

 forming the lateral or outer jjillars ot the abdominal opening. The de- 

 cussaling/c/sckw/i of the recti formed the mesial or internal pillars of 

 the same opening ; through which, as before mentioned, the epididy- 

 viis projected, inclosed in a muscular pouch or cremastcr, formed by 

 the fibres of the internal oblique and transversalis. 



" The pectorulis major arose from the whole length of the sternum, 

 and was continued into the deltoid without any line of separation, and 

 inserted with it into the upper and outer half of the /m/^en^A. Beneath 

 the preceding muscle were two distinct slips, or accessory pectoral 

 muscles, one arising from the lowest part of the sternum and inserted 

 into the anterior tubercle of the humerus ; the other arising from the 

 cartilages of the three lower true ribs, and attached to the posterior 

 tubercle of the humerus along with the sub scapular is ; between these 

 portions the long head of the biceps passed. A distinct slip from the 

 latissimus dorsi goes over the long tendon of the biceps to be inserted 

 on its outer or anterior side, the rest of the tendon being inserted as 

 usual. The pectorulis minor is inserted into the acromial end of the 

 clavicle, which has also a well-developed subclavius muscle attached 

 to it. 



" The situation and form of the testes have been already noticed : 

 they are the same as in most of the GUres. The epididymis was at- 

 tached throughout its whole length to tlie testis, following the greater 

 curvature of tlie ghmd, and measuring 1 inch 9 lines in length. 

 The tubuli testis were much more minute and tortuous than in the 

 Hut. The fatty processes that arc found liani^ing from tlic testes
