528 A DESCRIFTIOR of 



to that of the fore arm, for when the radius and uhia are 

 placed in their natural pofition, the breadth ot the bones of 

 the fore arm muft be fix inches, about the middle, and 

 6 48 incht s, at the lower extremity. 



'lie hones reprcfaitcd in plale No. 2, uelcn^cd to one of I he 

 paws. 



The upper row confifts of four feparate pieces arranged 

 in their natural order, one of which is iuppofcd to belong 

 to the metacarpus, and the other three to a claw or finger. 



Under the firft bone of the row, is another of the faiiie 

 iorm, marked alfo N o. i, the lower bone is much fmaller 

 than the uppermoft, although they appear to have joined 

 each other in the fiime paw — At their upper extremities 

 they refcmble metacarpal or metatarfal bones, as each of 

 them has an articulating furfacc for conned.ion with the 

 carpus or tarfus, and another on each fide for the other 

 metacarpal bones — they alfo refemble metacarpal bones, by 

 approaching to the triangular form at this extremity, for 

 the upper furface being broader than the lower, the fides 

 approach nearer below than above, and of courfe, when 

 they are arranged in contad: with each other, they form 

 an arch, correfponding probably with the concavity of the 

 carpus — Their lower extremities, inftead of a round head 

 or condyle, have a peculiar form, which the upper end of 

 the fmaller figure No. 1 reprefents imperftdly, for a high 

 ridge of a femicircular form, and a vertical diredion vhen 

 the bone is in its natural pofition, projeds from the articu- 

 lating iurface, and is received into a cavity of the next 

 bone (No. 2. b) — Articulated with this end of the large brne 

 iSo. I, is No, 2, which refembles neither the metatarfal bones 

 nor thofe of the phalanges, and is fo fhort that its length 

 is lefs than its breadth. 



The figures below, marked 2 a, 2 b, exhibit the arti- 

 culating furtaces ot this bone.
