its neck becomes cylindrical, then turns inwards, becomes 

 spread, and presents a long surface to the clavicle ; at the 

 external part, forwards, is an apophysis, which, with a cor- 

 responding apophysis of the clavicle, forms the pit in which 

 the head of the humerus is received. 



The clavicle agrees very closely in its form, both in its 

 head and body, with the scapula ; the edge of its flat part 

 being united to the sternum. 



The humerus is curved in two directions ; the upper 

 part is convex forwards, the inferior concave. 



The cubitus has no olecranon nor sygmoid surface : the 

 upper extremity articulates with the external condyle of the 

 humerus by an oval pit, Vr'idest on the radial side ; its body 

 is rather compressed transversely, and curved outwardly. 

 Its lower end is the smaller, is compressed transversely, and 

 is wider and descends a little lower on the radial side. 



The radius is nearly cylindrical, and thinner and shorter 

 than the cubitus. Its upper extremity is oval, the lower 

 oblong, thinner towards the cubitus. 



There are but four carpal bones ; a radial and a cubital, 

 the first of double the size of the other, and both contracted 

 in the middle ; a third, which may be considered as a pisi- 

 form bone ; and a fourth, lenticularly formed, placed be- 

 tween the cubital carpal bone and the metacarpal of the 

 index and middle finger. 



The metacarpal bones have a general resemblance to 

 those of quadrupeds. 



The thumb has two phalanges, the index three, the 

 middle and the next four, and the little finger three. These 

 two last having no nail, the terminating phalanx is very 

 small. 



The bone of the ilium is placed vertically : it is concave 

 outwardly, and convex inwards. 



The ischium is nearly in the form of the clavicle. It is 

 united to its fellow by a flat part in the form of an isosceles
