The sternum measures in length 4^ inches, and in breadth 2^- inches. 

 The large crista which is situated on its centre and anterior surface is 

 continued down the whole length of the bone— and is elevated above 

 the sternum at its most superior part l| inches. At this point is united 

 the OS jijgale, (merry thought) the cornua of which proceed outwards and 

 upwards, and nearly parallel with the two large clavicles, to meet the 

 scapulae at the point of either shoulder, where these three bones become 

 united by ligament, and form the glenoid cavity of the Humerus. 



The wing is composed of the following bones. 1st. The brachium — 

 which measures 5^ inches in length. 2iidly. The two bones of the fore- 

 arm (cubitus) in length 8^ inches. On the largest of these bones are 

 fourteen small prominences, arranged longitudinally, which denote the 

 attachment of the quills of the secondary feathers of the wing. 3rdly. 

 Two small bones of the carpus. One articulated by firm ligamentous 

 structure to the end of the small bone of the fore-arm. The other is 

 attached to the large bone, by means of a long tendon, which is 

 inserted at about the terminal third of this bone, and it is joined to the 

 metacarpus just below its articular surface by ligaments. This bone is 

 situated in the bend of the wing, and plays on the outer condyle of the 

 metacarpus. 4thly. The metacarpus consists of two bones consolidated 

 into one at either extremity, and open in the centre. It measures in 

 length 2'} inches. 5thly. The thumb (false wing) formed of one small 

 bone, articulated to the metacarpus on its edge, and immediately below 

 the carpal joint, fithly. The two fingers, that which lies on the same 

 line with the thumb, has two phalanges, the other but one. 



The Leg. Tlie first of these bones is the femur, in UMi^th t inches. 

 2nd]y. The tibia and fibula. Tiic fornirr measures C)^ inches in length. 

 The fibula, which can scarcely be ^^aid to exist, in most birds, is very
