Having thus shortly tiffany jewellery described the anatomy of the lymphatic system in the several classes of Vertebrate tiffany&co animals, we shall n roceed to offer a few remarks on the functions which it is supposed to perform in the animal economy. It is unnecessary to allude particularly to the opinions held by Swaminer dam, Boerhave, Monro, and other anatomists, even after the discovery of th lymphatics, that the function of absorption was performed tiffany sale exclusively by the veins. The reasonings, which they adduced, were founded on folse pee mises, and they cannot therefore much influence our speculations. It is to the labours of the two Hunters that we are tiffany rings chiefly indebted for having proved, beyond the reach of doubt, that the chyle is taken up by the intestinal absorbents, and conveyed by them into die general mass of the circulation. Dr. William Hunter indeed was inclined, for many years afterwards, to admit tiffany the co operation of the veins in this important operation of life; but his younger brother, endowed with a bolder and more independent mind, maintained that this opinion was quite inaccurate. By a series of well conceived experiments, he quite satisfied himself that the absorption of the chyle is performed exclusively by the lacteals. Having opened the abdomen of a living dog, and discovered those points where lacteals were full of milky chyle and others where the chyle was yet transparent, he took two portions of the intestine, and tiffany outlet passed ligatures around each, after havingtied the branches of the mesenteric arteries and veins which supplied them He then introduced some milk into each portion. The lacteals of one of these continued to transmit a white fluid; and those of the other, which hitherto had been nearly pellucid, began to be filled with a similarly obaque fluid, while the blood drawn from the veins presented no traces of milk. This experiment was repeated tiffany and co outlet several times without tiffany co tying the veins; and still the same results were uniformly obtained

For many years the doctrine, that the lymphatics were the sole and exclusive tiffany and co outlet vessels for absorption, was so undisputed, that it seemed that physiologists were scarcely aware that any other opinion had ever been held by their predecessors. Such was the state of opinion till the year 1809, when tiffany jewellery Magendie read to the French Institute his celebrated Memoir to prove that " the lymphatic vessels are not the tiffany sale only route by which foreign matters are admitted into the sanguiferous circulation." We shall briefly allude to a few of his experiments. A portion of gut in a living dog tiffany was tied, and then detached from all its connexions, save only from a single mesenteric artery Hemorrhage. A. This is seldom, for obvious reasons, considerable in the tiffany co child; but we quite agree with Mr. Key, that, in the adult, 44 it is not ingenuous for litho tomists to deny the occurrence, or the danger of haemorrhage," There are several sources that furnish the haemorrhage ; but in all cases, the bleeding comes most freely from the upper angle of the wound. The higher therefore the incision is carried, the greater, ceteris paribus, is the probability of bleeding. The pudic trunk itself is, I apprehend, rarely wounded. tiffany&co The artery of tiffany rings the bulb, and the super and vein by which it hung suspended, A small quantity of the Upas poison was then injected into its cavity, and the portion of the gut was then replaced in the abdomen. At the end of six tiffany outlet minutes, the general effects of the poison had developed themselves in their full intensity, just as if the bowel had still retained all its ordinary connexions.
