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 pignient. 



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

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

 to be very free. 



" Among the peculiarities of the muscuiar systemthe inostremark- 

 able is a blending together of the obUqui eiterni and recti abdominis 

 museles, 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 arisingthick andfleshyfrom the right os pubis,and passing through a 

 large slit in the origin of the right, which arose in atorrespondingman- 

 ner from the ospubis of the left side : as there was no tendon covering 

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

 as fleshy insertions of the external oblique, or decussated origin^ of the 

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

 ternal obliąue at the epigastric i-egion of the abdomen, and pass over 

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

 steriium, and have no other attachment to the pubishat through the 

 mediiim of the fibres before described. The external oblique museles 

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

 ing obliąuely do\vnwards, and blending \vith those of the recti, the 

 ]ower fibres being inserted distinctly into the rami of the pubiš, and 

 forming the lateral or outer pillars of the abdominal opening. The de- 

 cussaūngfasdculi of the recti formed the mesial or internal pillars of 

 the šame opening j through which, as before mentioned, the epididy' 

 mis projected, inclosed in a muscuiar pouch or crema^ter, formed by 

 the fibres of the internal obliąue and iransversalis, 



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

 and \vas continued into the deltoidwithoutany lineof separation, and 

 inserted with it into the upper and outer half of the humeriis. Beneath 

 the preceding musele \vere t\vo distinct slips, or accessory pectoral 

 museles, one arising from the lovvest part of the sternum and inserted 

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

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

 tubercle of the humerus along with the subscapularis ; bet\veen 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 ręst of the tendon being inserted as 

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

 clavicle, vvhich has also a \vell- developed subclavius musele attached 

 to it. 



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

 they are the šame as in niost of the Glires. The epididymis \vas at- 

 tached throughout its whole length to the tęstis, follovving the greater 

 curvature of the gland, and measuring 1 inch 9 lines in length. 

 The tubuli tęstis \vere much morc minute and tortuous than in the 

 Mat. The fatty proccsscs that are found Iianging from the testes
