Of HUMOVRS. 217 



happens to the veflels of the legs and ex- 

 treme parts. 



Thus we fee that a languid circulation. Limbs 

 relaxed veflels, and want of mukuhrf%^^ 

 power to pufh on the fluids, may, by i'^*- without 

 tarding the circulation, occafion fwelHngs humours. 

 in the extreme parts, without any fulpi- 

 cion of bad humours, or the blood's be- 

 ing at all in fault. This might be farther 

 illuflrated by thofe fwellings in man, called 

 the piles, where the afcent of the venal 

 blood interrupted by its own weight, the 

 want of force in the veflfels, and of aflifl:- 

 ance from the circumjacent parts to pufh 

 on the circulation : but, we hope, what has 

 already been faid, will fufficiently anfwer 

 ourdefign. 



The inference to be drawn from hence The cure 

 is, that the cure mufl: be difl^erently di- muft be 

 redled when the fweilinp; proceeds from ^ireaed 

 the blood and juices, and when from the -^ , 

 foiids or veflfels. In the former cafe, eva- 

 ruations and alteratives are neceflTary to 

 leflfen their qua: tity, and re6tify their qua- ' 

 lity; in the latter, externals, proper exer- 

 cife, and good diet. 



Conformably fwelled leg% arifing from ^"/^ be 

 poverty of blood, laxity of veflels, and ^f"^^ ^^
