part of the lower epiphysis, where it is articulated with the external bone of the 

 carpus, obliquely inward is 5 inches. This same epiphysis, with a convex sur- 

 face behind, from the right to the left, is 5 inches. 



The radius in length, from the external and upper part of the cubitus, on 

 which it lies, and with which it is united, running obliquely inward, is 1 foot 

 94- inches. At its upper part it sends a production outward 3-|- inches, by which, 

 with a part of the cubitus, it receives the external part of the lower epiphysis 

 of the humerus : from thence the bone is contracted at its fore part to 2-f 

 inches ; then descending 10^ inches, it becomes 2-1- inches broad ; thence it 

 enlarges gradually to the lower epiphysis, where, measuring from the fore part 

 of the cubitus to its opposite and back part, the radius is 84- inches ; thence 

 you descend 3 inches, to its articulation with the internal bone of the first rank 

 of the carpus. This bone is quadrangular above, descending to about the mid- 

 dle it becomes more convex ; from thence it is gradually enlarged, and during 

 the whole progress pretty free from the cubitus, except where it is conjoined 

 with it at its upper part : at the lower articulation, they are only separated by a 

 cartilage. The lower epiphysis of these bones is of a very unequal surface, and 

 though not separated from them by boiling, yet plainly distinguished by their 

 cartilages, which are not yet ossified. 



The fore foot (as the hand in human subjects) consists of the carpus, meta- 

 carpus, and fingers, or rather toes. The carpus has 6 bones disposed into 2 

 ranges, diflfering in figure from each other, rugous before, endued with several 

 holes for transmission of blood vessels, and of a convex surface behind, having 

 several inequalities for insertion of tendons. 



There are six bones in the metacarpus, per ginglymum longum ; viz. they 

 are received above by the bones of the second rank of the carpus, and below 

 by the toes. They are all of much about the same figure, but not of an equal 

 length ; somewhat flat before, and both convex behind ; broader at the upper 

 and lower extremity where they touch one another, and narrow in the 

 middle. 



Each of the 6 toes of the fore foot consists of two thick short bones; 

 whereof the first of the external toes is 54- inches round, and J^ inch long, the 

 second about 1 inch broad, and -j- inch long, weighing 2^. The first bone of 

 the second toe is 2 inches long, and 64- inches round; the second is l-^- inch 

 from the right to the left, and -l- inch from above to below, weighing 3f . The 

 first bone of the third toe is 2 inches long, and 74- inches round; the second 

 bone is divided into two in this subject, in figure not unlike an ox's hoof, whe- 

 ther it be a lusus naturae, or peculiar to all other animals of this species, I know 

 not, weigh 4§. The first bone of the fourth toe is 24- inches long, and 54-
