by a large lymphatic (b), which runs upon the cefo- 
phagus, and can be traced as far as the lower or glan- 
dular part of that canal ; from which part, or from 
the gizzard, it feems to iffue. The thoracic duds 
are joined by the lymphatics of the neck (and pro- 
bably by thofe of the wings) juft where they open 
into the jugular veins. 
The lymphatics of the neck * generally confifl of 
two pretty large branches, on each fide of the neck, 
accompanying the blood-vdfels. Thofe two branches 
join near the lower part of the neck ; and the 
trunk is, in general, as fmall, if not fmaller, than 
either of the branches. This trunk runs clofe to the 
jugular vein (ii), gets on its inlide, and then opens 
into a lymphatic gland ( k k). From the oppofite fide 
of this gland, a lymphatic comes out, which pours 
the lymph into the jugular vein. On the left fide, the 
whole of this lymphatic joins the thoracic dud of the
