1 2 The Anatomy of a HOKSE, Chap. IL 



§ . IV. Of the Spleen^ Pancreas, and Liver ^ with the 

 Porus Biliarius, or Gall-pipe, 



Ihe Spleen. *^^^ Spleen, or Milt, is a foft, fpungy 



Subftance of a black livid Complexion, a 

 triangular Shape, but fomewhat longifh, fituated on the 

 left Side, oppofite to the Liver ; it adheres both to the Mid- 

 riff and Stomach : It is covered with a Membrane from 

 the Peritonccum, which, becaufe of its foft fpungy Sub- 

 fiance, is confiderably thick. It Veins are a Branch of the 

 Porta : Its Arteries fpring from the left deliack Branch, 

 and its Nerves from the left Intercoftal. It has alfo Lym- 

 phatick Veflels, which glide along the Caul to the Recep- 

 tacle of the Chyle. There is no Part of the Body v/herein 

 Anatomifts have differed more, than concerning theUfe of 

 theSpleen : To pafs by a great many various Opinions about 

 it, it has been thought to give an Afperity and Sourifh- 

 nefs to the Blood which comes into it -, and as that Blood 

 is conveyed from thence to the Liver, it was believ'd to be 

 in order to ingender, or to keep up a moderate Ferment in 

 it; but becaufe feveral Animals have liv*d after it has 

 been cut out, and been more brisk than when they had it, 

 it is not therefore improbable, but it has fome other Ufe 

 not yet known; efpecially lince the modern Difcoveries 

 allow of no fuch Ferment. It is however certain, that it 

 ferves to cherifli and fupport the left Side of the Stomach, 

 as the Liver does the right, to further Digeflion. 

 g^, n The Sweetbread or Pancreas, fo czlkd 



head ' becaufe it is altogether flefhy, is fituated un- 

 der the back Part of the Stomach, and lies 

 crofs the Belly. It is a white and foft glandular Subftance, 

 Itoied plentifully with fmgle Kernels over its Surface, which 

 Its Veffels ^^^ fomewhat prominent, and of a reddifh 



■^* Colour. It has its Cover alfo from the Pe- 



ritonaum. Its Arteries fpring from the Caeliacal, and its 

 Nerves from thelntercoftals ; its refluent Blood is fent into 

 the Liver, as that of the Spleen : Befides, it has a PafTage 

 into the fiiH Gut a little below the Stomach, which is call'd 

 the Pancreatick 'JDu5i. The Liquor which that Duel dif- 

 charp;es, is believed, in conjundion with the Gall, to fweeten 

 the Chyle, to free it from all manner of Impurities. This 

 Liquor feems chiefly to be derived from the little Glands 

 which are on iis outfide, there being a great maiiy little 



Pipes^
