differs from that in birds, in not having any glands upon ; 
the larger lymphatics of the neck j at leaf! I am inclined 
to believe fo, from not having feen any in the dif- 
fedlion of one animal of this fpecies in which I looked 
for them. It likewife differs from that in birds in 
another circumftance, to be taken notice of hereafter. 
Whether it agrees with the fame fyftem in birds, in. 
the tranfparency and want of colour in the chyle, I -. 
cannot take upon me to determine, as 1 did not fee„- 
any of that fluid in this fubjedt [a). 
The following defcription I took from the animal, , 
after I had injedted the larger branches of this fyftem i 
with a coloured wax, and the fmaller v/ith quick-- 
iilver. To avoid my being mifunderftood, when T 
fpeak of the fitaation of the different parts,,! fhall 
mention, once for all, that the defcription was taken? 
from the fubjedt as it lay upon its back; thofe parts 
being called higheft which were neareft the head,, 
thofe loweft; which were neareft the tail, thofe pofte- 
rior which w'ere neareft; the back, and thofe anterior;- 
neareft the belly 
The ladleals accompany the blood-veffels upon the • 
mefentery, running by their fides, and communicate - 
frequently aCrofs thofe veftels. Near the root of the,, 
mefentery they anaftomofe, fo as to form a net-work, , 
from which feveral large branches go into fome con-- 
fiderable lymphatics lying on the left fide of the fpine,

John Hunter, the chyle was white.

large, meafuring from the lower to the upper part of the fheli s 
two feet fsven laches, and two feet two inches from fide to j
