An Afcitfcs There are very different Opimons about the Man- 

 or Dropfy, ner how a Dropfy of the Belly is produced, borne 

 the Man- i^^^[^q it proceeds from the Liver which is cover'd 

 Wd"" by t thin Membrane, and that when this Mem- 

 brane happens to be feparated by a waterilh Hu- 

 mour iffuing out of the Capillary Lymphatics, 

 Pu/Iules or little Bladders are form'd, which contain 

 a clear waterifh Lymph ; and if thefe break, the 

 Water falls into the Cavity of the Belly, and caufes 

 the fame to fwell like a Drum. Others, and par- 

 ticularly our Countryman Dr. 7f ////V, think the 

 Dropfy of the Belly proceeds from a Rupture of the 

 Lacleal or Milky Veffels fpread about in the Me- 

 fePtry or Net of Animals. But I am rather in- 

 clined to believe, that as there are a Number of Lym- 

 phatic Veffels which pour out a watry Liquor upon 

 the Chyle as it paffes along the middle Coat of the 

 Mefentery or Net, the Lymphatics are broke, ^ and 

 ouze out Water into the Cavity ot the My , mfo- 

 much that the Guts fwim in it as m a P^^l ^'^ll «* 

 Water. But what tbofe Paffages are by which the 

 Waters are difcharged out of the Cavity of the M- 

 domen or lower Belly into the Inteflines, &c. is yet 

 very uncertain : Bat it appears by Experience, that 

 an Infufion of C; -..;.. Uetallorv.m, or what is called 

 Vimm Benediaum, powerfully forces off watry 

 Humours from the Outfide of the Guts in an 

 Afdtes both upwards and downwards, which, as it the 

 Obilacles were removed, it runs plentifully off by 



biool.
