4 inches, and from the same protuberance to the extremity of the processus 

 coracoides, is 3^ inches. This processus coracoides is that part of the spina 

 which runs toward the neck of the scapula, but does not, as in men, defend 

 the humerus from dislocation. It is very rugous and convex before, but con- 

 cave at its back part, being 3^ inches broad at the point, it ascends J 1 inches, 

 where it is raised 5 inches from the body of the scapula ; it inclines a little 

 backwards, and ascends 12 inches more, till it be lost where the epiphysis be- 

 gins, being still concave at the fore, and convex at the back part. From the 

 spina it sends forward a production 8 inches long, 3 inches broad at its upper 

 part, 2 inches about the middle, where it is crooked, and 1^- inch at its lower 

 extremity, where it is thin and sharp ; but at its upper part thicker and rugous^ 

 concave at the inner, and convex at the outer side. This process serves to 

 keep the musculi supra-spinati within their bounds, when they pull up such a 

 vast weight as the fore leg. As the spina runs up 5 inches from this production, 

 it is rugous and thick in its edge, from thence it becomes gradually thinner till 

 it comes to the epiphysis. The back and upper part of the scapula is very thin, 

 and sharp from the neck, l6 inches upward, from thence it ascends 5 inches to 

 the place where the spina ends, and forms a very rugous and spongious epi- 

 physis, thick at the upper end, thence it descends obliquely 2 feet, whence its 

 fore edge runs obliquely in toward the neck 10 inches, being sharp ; thence it 

 tends outwards, and descends other 5 inches, till it comes to the neck. All the 

 upper part of the scapula is covered with an epiphysis, spongious and rugous, 

 which separated by the boiling, and is a further argument that this animal was 

 young, according to their term of life ; it is otherwise a very thin bone and 

 solid, except where the epiphyses are. 



The humerus is a very irregular bone; its head is in circumference 2 feet, 

 having 2 remarkable epiphyses, one by which it is articulated with the scapula 

 from before to behind, with a convex surface 8 inches, and from the right to 

 the left 4-^ inches, and another on the outside rising higher and sharp, about I4- 

 inches. Round this epiphysis is 1 1 inches, and from before to behind with a 

 flat outside 64- inches. Between the epiphysis, which receives the scapula, and 

 this protuberance, is a sinus about 3-i- inches broad, and about li inch deep ; 

 as it descends toward the inside it becomes deeper, and only 2 inches broad : it 

 is for lodging the external tendon of the biceps, analogous to a crena, for the 

 same purpose in human subjects. The neck of the humerus is in circumfer- 

 ence 19 inches, flat behind for the space of 4 inches, then forming an angle, 

 and running obliquely outward 3 inches, then passing forward below the utmost 

 protuberance 5 inches, thence crossing the fore-named sinus it runs back, first 

 flat, then a little convex, 7 inches. Below this outward protuberance there is
