chyle directly into the venous circulation : so called from 
its course through the cavity of the thorax. In man this 
duct i.s from 15 to 18 inches long ; it begins opposite the 
second lumbar vertebra, by a dilated sac or cyst (the 
receptaculum chyli or cistern of Pecquet), and runs up to 
the root of the neck, alongside the vertebral column, pass- 
ing through the aortic oriiice of the diaphragm. It ends 
in the venous system at or near the junction of the left 
internal jugular and subclavian veins. It is composed of 
3 coats, and is provided with valves. Its caliber varies 
en that of a crow-quill and of a goose-quill. Whar-
