" Plura promiserat Antonius Nuck, et poterat de ejus viri industria magna inciso- sorum expectatio esse. Integrum enim vasorum lymphatieorum systcma amalgamate repletum siceaverat, sed pertinaeem in CO labore virnm, ct per plura animalia sua vasenla persequentem, mors ante diem abstulit.

Ipse enim testimonium pro Nuckio tlixit Hermannus Boerhaave, tabulasquc vasorum lymphatieorum vidit, qua: argento vivo repleta \‘ir industrius continuata siecaverat." I should be exceedingly sorry to detract from the reputation of any iii- dustrious anatomist; but the appearances he has caused to be engraved are not like what I have seen. It is very evident, that he sometimes described from quadrupeds; it is to me also very evident, that he describes from his own imagination. He is right in describing the absorbent glands as cellular; but neither his engravings of those glands, nor some others that I 131 radaveribus, et in vivis animalibus, vasa lymphatica et vidi, et persecutus sum. I'lurima tamen ubique desunt, neque in artubus, aut dorso, aut in- teriori capite ea vascula hactenus satis certo visa stint, neque constituta radices aut extremi termini." The description of the absorbent system I am about to give, is in most things the same with that which I gave at lectures since the year 1773, as I formerly observed, particularly that of the absorbents of the liver, and of the lungs, and pancreas, which were not known to Dr. Hunter himself; the last, particularly, neither to Haller nor Mr. Hewson. Every yearI added such varieties as I had discovered. Most of the pupils at Windmill Street took notes; and copies of my description are in the hands of a vast number of students. I have used, in the First Part of this treatise, for the most part, the terms lzlctmlr and lymphatics, instead of absorbwts, in order to avoid all ambiguity concerning the vessels meant; but, having there disproved ab- sorption by red veins, I cannot now be misapprehended, and shall in future employ the term abrorbcnts, to signify lactwls and lymphatics; and shall write glands (f [lie absorbent: instead of lymphatic glands. I must also remark, that neither the glands of the absorbents, nor their vessels, are so Haller, have seen, very much resembling them, are according to nature. indeed, says of him, " Pari facilitate vasa lymphatica ostendebat ut alii constant in their situation and distribution as the arteries; in which respect rubra," and that he injected these in Vacuo: " Antlia pneumatica ad eum scopum usum fuisse."-He also informs us, that he made use of an amal- they resemble the red veins. most frequently. gain of quicksilver. This does not correspond, however, with what he afterwards says: " Nuckium adipc aliquo argentuni vivum eoegisse." Another general observation I wish also to premise is, that, independent of those absorbcnts which accommpany the arteries, and which are usually This mixture would not pass into the absorbent vessels readily, in the way one, on each side, there is on the extremities a set of cutaneous absot‘hents, we now inject: I cannot say what might happen, if the vessels were in- Jected in vacuo; but I have a great many doubts on this subject. Some attempts have since that period been made, and some things have been added to the history of the absorbents, by Meltel, Hewson, and Haller; but the description is still incomplete, as Haller himself confesses: " Ill. Meckelius passim ad eorum historiam aliqua addidit, tum Alexander Monro fil. et potissimum Guil. Hewson, qui multas novas ex humano c0r~ pore «um...» 0;..." W713?" Ave-f" waumw I have here described them as I found them accompanying the larger trunks of the cutaneous veins, as the saphena major and minor, in the lower extremity; the basilic and cephalic veins, in the upper extremity. There is also on the viscera commonly a superficial and a deep-seated set; the first run by themselves, on the surfaces of the viscera; the second accompany the principal blood-vessels of the viscera, and ramifyin the same manner. This distinction takes place even amongst the absorbents of the intestines themselves. 5 2 Previous |
