foon after, by a lymphatic which runs upon the fide 
of the fifh. This lafl-mentioned veflel confifls of a 
trunk running on the fide juft oppofite to the ribs, 
and from this trunk proceed branches on each fide 
immediately under the fkin j fo that it has a beauti- 
ful penniform appearance. Befides thefe branches, 
there is another fet deeper feated, which accompany 
the ribs. After the large lymphatic has been joined 
by the above-mentioned veflels, it receives the lym- 
phatics from the pofterior extremities of the gills, and 
having now got as far back as the orbit, it next re- 
ceives lymphatic veflels from that cavityj but thefe vef- 
fels do not belong merely to the orbit j for one of 
them comes from the nofe, and another from the 
upper part of the mouth. A little below the orbit, 
another net-work appears, confifting, in part, of the 
veflels above defcribed, and of the thoracic dudt. 
This net-work is very complex ; fome of its veflels 
lie on each fide of the mufcles belonging to the gills, 
and from its internal part a veflel goes into thejugular 
vein, by which veflel the whole fyftem is terminated. ' 
The large lymphatic above mentioned, which lies 
upon the bone of the thorax, has likewife a procefs 
running towards the upper part of the kidney, and re- 
ceives fome of the lymphatics of that organ. 
The ladeals run on each fide of the mefenteric ar- 
teries, anaftomofing frequently acrofs thofe vef- 
fels. The receptacidum, into which they enter, is very 
large in proportion to them, and confifts, at its lower 
part, of two branches, of which one lies between the 
duodenum and ftomach, and runs a little way upon 
the pancreas, receiving the lymphatics of the liver, 
pancreas^ thofe of the lower part of the ftomach, and
