very fmall, but have notwithftanding the be- 
nefit of the fkin. ;

likewife of the manner in which it ferves to

rings of their natural fize. 
x A mufcle in the centre of the acetabulum, 
as likewife the manner in which this part is 
entirely compofed of mufcular fibres. On 
the upper part may be feen the black edge of 
of a horny bone, in form of a ring, of 
confiderable fervice in the conftruction of 
this organ. 
2 The internal cavity of the acetabulum, its 
fibrous and mufcular ftructure, as likewife 
the black edge of the ring, juft now menti-
