thofe Veffels of the Body, which we call Ijw- 

 phatics. 

 Lymphatic Thefe are flender, pellucid or traniparent Tubes, 

 Veflels, whofe Cavities are contra£led at fmall and unequal 

 v^hat. Diftances, by two oppofite femilunar Valves, which 



permit a thin and tranfparent Liquor to pafs thro* 

 them towards the Heart, but which Ihut like Flood- 

 gates upon its returning. 



They arife in all Parts of the Body, but after 

 what Manner needs no great Difpute ; for without 

 Doubt all the Liquors in the Body ( excepting the 

 Chyle hefore defcribed) are feparated from the 

 Blood, in the fine capillary or Hair-like Veffels, by 

 a different Pipe from the common Channel m 

 which the Reft of the Blood moves : But whether 

 this Dua or Pipe be long or Ihort, vifible or invi- 

 fible, it is ftill a Gland, while it fuffers fome Part 

 of the Blood to pafs thro' it, and denies a Paffage 

 to other Parts of that Fluid. Now, the Glands, 

 which feparate the Lympha mull be of the fmalleft 

 Kind, being invifible thro' the fineft Microfcope 

 that has yet been contrived ; but their excretory 

 Duds or difcharging Orifices, the lymphatic 

 Veffels, unite with one another, and grow larger as 

 they approach the Heart ; yet they do not open in- 

 to one common Channel as the Veins do ; _ for 

 fometimes we find two or three, nay fometimes 

 more Lymphatics, running by one another, which 

 only communicate by fhort intermediate Du£ls, and 

 which unite, and prefently divide again. 



In their Progrefs they always touch at one or two 

 conglobate or veficular Glands, into which they 

 difcharge themfelves of their Lympha or watry Hu- 

 mour ; which Liquor, if chymically examined, 

 will be found to contain a great deal of volatile but 

 no fixed Salt, fome Phlegm, fome Sulphur, and a 

 little Earth. 



The Ufe of the Lymph m?y be gathered from 



the Confideration of the Parts into which it dif- 



charres itfelf, which are the Receptasulum Chyli in
