He supposed them a fifth set of vessels; and as they neither carried red blood, like arteries and veins, nor chyle, like the lacteals, btit a transparent lluitl, like scrum, he calls them Vasa Serosa. About the same time, Bartholin, the Dane, also saw these vessels; but, independant of the hints he received from Veslingius, there are suspicions that he must have previously heard of Rutlbeek's discovery; for, in his publication on this subject, he says, " Sibi vasoruin serosorum nomeu non plactre quod aliqiii his vasis iinposut‘t'int."-l3artholin changed the. name into V'asa Lympliatiea, a name they have still retained; for, as he first published an account ofthem, and as he was a titan (ifmo're. eminence than Rud- beck, the whole medical world gave him the credit of the discovery. He himself, however, seems to be content to share this discovery with Rttd- beelt and Jolyfl‘e: " Similes aquosos, ducttts detexit et postea descrip- stt Olaus Rudbeck: in Anglia dc jolivio quoqtte SuO gloriantur amici; quin nobis, cum aliis hinc inde visa stint negare iiolim; sed nobis qtti primi in arenam descendimus nullus mortalium viam demonstravit." Bartholin having mentioned Dr. Joly/lie, it may be proper also to state the grounds ofhis claim to the discovery of the lymphatics. Glisson says that in the beginning of' June, 1653, Dr. Jolyfle, who was then taking; his degree at Cambridge, informed him, " Dari vasorum quartum Genus a ve- in., atteriis, nervisque plane diversum, idemque ad omnes aitt plurimas salient Corporis partes distribui, et littinortim aquosum in se complecti.

Charleton also says, " Norunt autem e doctissimis isthoc vasorum genus novtim s Complure s candidati tttm sociis tum Collegii seripto publieo per anuos, aliquot anteqtiani Bartliolinus de co quieqttam usus est un- divulgarat a Jolivio nostrate, qtio aceuratius felieiusve nemo indulsissent vitam n longiot'ei Etta si eui et , anatomieo cultello qnain SCEpiuS ct observattnn litisse." an acCident too, as himseli' And Boyle attests the same thing:--" By Dr. ~]olyli'c, first light upon hath told me, ditl our industrious anatomist, s the ingenious Bartho- these yet freshly detected ve sels; which afterward for them, hath met with, linus, without being informed ol'thcm, or seeking Yasa Lymphatiea." and acquainted the world with under the name of I have considered the Though, in compliance with anatomists in general, given the history of have and parts, two of consisting as Absorbent System lymphatics are the discovery oi~ each part; yet, in liter, the laeteals and In birds, the eliyle and SEllllL' animal. branches ol‘one common trunk in the and when viewed in lvniph are similar in the ir appearance to the naked eye, distinguish the one. nee,to app their from ble, impossi is the microscope, it ment,hitherto made, shewn from the other; neither has any Chemical experi In animals, where they are per- how totlistinguish the one from the other. asin the diaphragm, i‘ectly distinguished in their appearance, the same vessels, as I have often seen, andas is sometimes carry the one, sometimes the other, even the thoracic duct itsell‘has confirmed by several emine ni anatomists; says Noble, " fui 'e receptaculi been seen tinged with lymph: " puriorem," says, " cutn lac esset iti vasis Ilaller dii;" pericar lympha quam htimorem, and again, " Porro vulgare :" fuisse m lympha eo, laeteis vidi in ductu thoraci laete, expectatitm, V' sa qttm pulclic‘rrima omniiio experimentum Cst, Iitfqtic intetitis ineisoris diaphano humore plena ex intestinis prot libant sub ooulis otnnino etiain i, vel dutn vivit animal, vel et lympha etiam rubella repler .
