) mentation OF the chyle: 2. to prick the guts by its tharpnefs, ‘to {tir up their peri-. 
ftaltic motion, that they may drive down the chyle, and expel the excrements : 3. to 
mix with the:chyle in fuch Proportion, that, being converted into ss the blood 
might thereby be kept from congelation. ' 
To illuftrate this fubje& more amply, we have fabjoined. a reprefentation of the 
liver of a new-bori child, where A A A A reprefents the circumference of the liver ; » 
BB BB, the lower part of the liver, in which there are feveral irregularities ; C, the. 
gall:bladder, D, the umbilical vein, running with a fingle trunk from che navel to 
the liver; E E E,*the finufes of the vena porta, into which alone the umbilical - 
vein inferts itfelf, with a fi ingle trunk; F, the trunk of the vena parte cut off; 
G GGG, the principal branches of the fiius of the vena ports diftributed through . 
the liver, which become confpicuous when a fmall part of the fuperficies of the liver 
is abraded off; H, the trunk of the vena cava; IJ, the canalis venofus, or ductus » 
_-venofus, arifing from the finus of the vena porte, over-againft the ingrels of the . 
umbilical vein, and infertine itfelf into the vena cava: this, in the uterus, carries a. 
reat part, and probably the greater part, of the blood, cartied through the umbi- 
lical vein to the liver of the foetus, by a large paffage to the vena cava and the heart; , 
but this, after the birth of the foetus, gradually grows narrower and clofes; A, the : 
entrance of the umbilical vein into the finus of the vena porte. To this defcrip.- 
tion of the external part of the liver, it may not be improper to add chat of its blood-. 
veffels, together with their numerous ramifications, freed from the parenchymatous . 
fubftance. Fig. 1. reprefents the under fide of thefe veflels; A being that part of « 
the'liver which lies next to the back ; B, its right fide; C, its anterior edge; D, its « 
left fides Ei, the vena cava, where it pafles through the diaphragms Er, Ea, E 3, . 
its three principal branches, diftributed almoft through the whole liver; F,the vena » 
porte turned upwards, that other vefiels may be more eafily feen; F1, F2, F 3, F 4, . 
four branches of the vena porta: diftribated to feveral quarters of the flat part of the 
liver, but the fifth branch is not obferved on this fides G, the gall-bladder ; if, .
