k only differs from the mufcle of the fecond ring, in that it is* 

 crofted by the oppofite mufcle, whereas k croffes.the. oppofite 

 mufcle. 



As the mufcles 1, n, o, p, of this ring are fimilar to thofe of 

 the preceding one, they need not be defcribed. 



q is a triangular mufcle ; the bafe of it is fattened to the laft 

 fold of it's ring, on the lower fide it is fixed to the mufcle o, thfc* 

 fummit to the Ikin at the edge of the cavity for the leg. 



The eight following Rings,, 



We difcover here the gaftric mufcles, i, R, Y, m>. 



The mufcle i is quite ftrait, and is placed at a little diflance- 

 from the inferior line ; it is broad at the fourth ring, but diminifhes 

 gradually in breadth to the eleventh. It is united at the fourth* 

 but is divided into two heads, which divaricate in the^ following 

 rings. In the fix next rings thefe heads are fixed nearly at the 

 fame place with a and f ; in the other two it terminates at the 

 fold of the ring. The anterior infertion of the firft and laft is at

k is an oblique mufcle, whofe lower infertion is at the ikin near
