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

 Porus Biliarius, or Gall-pipe. 



The 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 Peritonaum, which, becaufe of its foft fpungy Sub- 

 Hance, is conlideraWy thick. It Veins are a Branch of the 

 Porta : Its Arteries fpring from the left Caliack Branch, 

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

 ■phatick Veflels, which glide along the Cayl to the Recep- 

 tacle of the Chyle. There is no Part of the Body wherein 

 Anatomifts have differed more, than concerning theUfe of 

 theSp'een : To pafs by a great many various Opinions about 

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

 jiefs 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 fince the modern Difcoveries 

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

 ferve» to cherifh and fupport the left Side of the Stomach, 

 •as the Liver does the right, to further Digeftion. 

 yy o , The Sweetbread or Pancreas, fo called 



bread ' 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, 

 ilored plentifully with fingle Kernels over its Surface, which 

 Jts VefTl ^^^ fomewhat prominent, and of a reddifh 



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



ritonaum. Its Arteries fpring from the Casliacal, and its 

 Nerves from thelntercoftals ; its refluent Blood is fent into 

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

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

 the Pancreatick tDu^, The Liquor which that Duct dif- 

 charo;es, is believed, in conjunction with the Gall, to fweeten 

 the Chyle, to free it from all manner oflmpurities. This 

 Liquor feems chiefly to be derived from the little Glands 

 v.hich are ou iis ouilide, there being a great many little 



Pipes
