vius, and subscapularis, present little peculiar. The 

 teres major is very strong, and proportionally broad- 

 er than in man. The levatores scapulae et claviculse, 

 have been already described. The two last are 

 united by cellular substance, so as to resemble one 

 muscle. The biceps flexor and triceps extensor 

 cubiti, the coraco-brachialis, the brachialis internus 

 and anconeus, exactly resemble the human. The 

 same may be said of all the muscles of the fore- 

 arm, except that there is no opponens pollicis in 

 this animal, and that the flexor longus pollicis 

 seems rather a part of the flexor profundus than a 

 separate muscle. The palmaris longus, which did 

 not occur in Dr Tyson's Orang, was very distinctly 

 formed in one arm of our animal, but wanting in 

 the other. The elbow-joint in this animal is ca- 

 pable of perfect extension, which is not the case in 

 the baboon. In the latter, it seems to be chiefly 

 owing to the manner in which the supinator radii 

 longus is attached to the external condyle of the 

 humerus and the neighbouring ridge. The pro- 

 nation and supination of the hand, with the flexion 

 and extension of the Wrist and fingers, are perform- 

 ed by a mechanism so similar to the beautiful con- 

 trivances employed in man, that one might almost 

 study human anatomy in those parts of the Orang 

 Outang.
