Mr. Heii'son, however, appears to have been the first who distinctlv made out llIIS trunk; for these other anatoniists, though they knew the termination in the right suhclaviaii vein, constantly described them as numerous, not, forming a common trunk. Though Hallt‘r quotes Mr. I'lcwson, respect- ing these terminations, he does not sat \thvther he made it a shit e termi- A nation, or a number of terminations.

Ilewson's words are, " The lymphatic vessels of the right side {01‘1" four considerable trunks, whichjoin near their termination. ~These trunks are, first, one from the upper extremity; secondly, the trunk of the lymphatic vessels of the right side ofthe head and neck; thirdly, a lymphatic from the tliyroide gland; lotirthly, the trunk of the lymphatics from the fore part of the lungs of the right side." He has here omitted the lymphatics from the right side of the heart, as well as those from the liver and diaphragm, and the vessels accompanying the internal mammary arteries, which he certainly had not seen. Indeed it frequently happens, that there are more in- sertions than one in both subclavian veins; and, though the insertions into the angles between these and the jugulars appear to be the most accurate, yet it does not seem to he of that consequence as not to admit of some I'IitllC‘l: subject. quadrupeds, but it was very easy to transfer it to the human pede * anteriori says, " lta Nicolaus Steno ex dextro capitis laterc, dextro little deviation; accordingly, \\'C find insertions sometimes in thejugulars, ."
