It also runs oblique ly from below upwards, in the direction of the left ligament of the liver. Its principal trunk also perforates the diaphragm, and, taking the sweep of the ribs, runs from behind forward, and terminates also in the glands, upon the pericardium, already mentioned. I have seen some branches from it also run backward, and terminate in glands upon the (esophagus, immedi ately above the diaphragm. I have seen other vessels from the same quarter taking the same course, and passing under the aorta to the thoracic duct. While I was injecting the absorbents on the small lobe of the liver, in April 1773, the mercury entered the principal trunk, but presently stopped in that absorbent, though it continued still to flow from the injecting tube. I suspected, at first, that way it wards, in the direction of the right ligament of the liver; in its the quicksilver, by its weight, had ruptured the vessels, and was running off into the cellular membrane; but in a few seconds I was agreeably dis- receives innumerable small branches, and very frequently even considerable trunks. I have seen, sometimes, almost the. whole convex surface of the right lobe covered with its branches. "then it comes to the 2ightlig:men3t, it penetrates the diaphragm, and, appearing on its upper sur ace 1p t e; - which were rising out of the substance of the liver, and which, running upon the left ligament of the liver, joined the trunk I had been injecting. I afterwards slit open that branch of the vcna portarum, which ramifies appointed, by seeing tlic mercury return from several absorbent vessels, e- through the small lobe of the liver, and found that the mercury, which had liiiid forward, to go into the glands already mentioned, on the fore parlt of the pericardium, and to join the former trunks. One of 111: branc ies, thrice as large as a crow-quill, after it had perforated the dtap ragm, "1:5 escaped from my sight during the injectionjust mentioned, had been filling the deep-seated absorbents, which were now seen running in great num- bers on the outside of the branches and part of the trunk of the vena por- tarum, and that it was from these deep-seated ones that the superficial branches on the left ligament had afterwards been filled. The description I have given of the absorbent vessels on the convex surface of the liver, is that of their usual appearance; but I have often seen six, eight, or ten smaller trunks running upwards, towards the dia- phragm, between the right ligament and the suspensory ligament, and four or five others, in the same situation, between this last ligament and the left one. These sometimes perforate the diaphragm, and, joining some of those on its upper surface, form aplexus, which runs with the mammary arteries and veins of each side, under the cartilages of the ribs, passes vitv of the thorax, it takes the circular sweep of the ribs, and runs rom t e backward, and climbing over the side of the spine, was inserted into thoracic duct, behind the oesophagus, without passing through any gland. In its way to the mediastinum, the principal trunk also communicates frec.1 quently with others, which run with the phrenic nerves, to be mentione hereafter. I have seen it divide at the place where it usually perforates the diaphragm, and one half go through the diaphragm, whilst the other run between the diaphragm and liver, and entered the glands of the portals. This trunk, instead of perforating the diaphragm, frequently runs wholly on the under surface of that muscle obliquely, in the direction of the cm- liac artery, and is near it inserted into the thoracic duct. through small glands in the course of those vessels, and terminates at last, " I have lately seen them passing into the duct without the intervention ofthese glands.
