a I 
enteric vein in mammals as eventually joining the vitelline to form the 
portal vein. CHARPY (2) also states the relation correctly, and credits 
LuscaKa with the discovery. HOCHSTETTER (8) cites and endorses 
the statements of ALLEN (1). 
The large sinus-like dilatations of the lower portion of the jugular 
(anterior cardinal) veins are very evident in the model (Figs. 2 and 3 ac). 
Finally it may be worthy of note that in this embryo the umbilical 
vein in two places divides and reunites. (The vein shown in the model 
is the left umbilical vein, the rudimentary right umbilical vein not 
being represented.) Below the distal portion of the intestinal loop, 
while still lying in the wall of the umbilical cord, the umbilical vein 
divides into two equal branches, which immediately reunite (not seen 
in lateral views of model). In the body wall below the liver (Fig. 2 v) 
the umbilical vein again divides, this time into three branches, one 
large and two small, which soon reunite into a single trunk before 
entering the liver.
