a ftreio-ht Line from their Origin, at the Sides of the above- 

 mentiSn'd Griftlc, and the Ends of the Balhrd Ribs to 

 the Share-bone, where they are inferted. There are in 

 thefe feveral tendinous Interftices, which are theCaule 

 why fome Anatomifts have divided them^ into divers 

 Mufcles. They fhorten the Belly, by drawing the Brealt 

 and Share-bone towards each other. . ^; „ -j.

 Pyramid, being broad at bottom, and growing gradually 

 narrower towards the Top. They feem to be derived from 

 the Ilreight Mufcles, and are aflifting to them m contrac- 

 ting; the Belly. ^ . rrr rr r r 



The lail arethe Tranfuerfe or Crofs Ue Tranfverfi 

 Mufcles, which have their Origin from the ^^^'*- 

 lowermoit Ballard Ribs on each Side, from the tranfverfe 

 Procelles of the Joints, or Vertebras of the Loins and 

 Haunch-bones, from whence, running acrofs the Belly, 

 Ihey are inferted in the White Line. 



Befides that thefe Mufcles are a Cover and Support to 

 the lower Belly, they have not only their particular Of- 

 fices, butaa in Concert with each other, and give their 

 mutual Affiftance in compreffing the Guts, to the Lxpul- 

 fion of their Excrements. ^ ^, -d v 



Underneath the Mufcles lies the Perito- "Th^ Peri.o. 

 neutn, which is the next proper Tegument nxum. 

 of the Guts. Is is a double Membrane, of an oval i* 1- 

 sure, and is thought to derive its Origin from that 

 which involves the Pith of the Loins ; its Infide is very 

 fmooth, and lined with a fort of Mucus, which proceeds 

 from the Guts, over which it is fpread. From this Mem- 

 brane all the lower parts of the Belly are furnifhed either 

 with their common, or proper Membranes. It has Liga- 

 ments, whereby it helps to bind all the Guts in their proper 

 Situation, that no violent Motion may difplay them ; it 

 alfo afFords a ftronger Ligament to the Liver, and is a 

 great Support to a vaft Number of fmall Veflels, whic^ 

 would either be broke, or twifted in fo long a Courle, 

 were they not preferved within its Duplicature.
