fooncr on the Lungs than on other Parts, is^ 
bccaufe much greater Quantities of Blood, 
do, in proportion to their Bulk, pafs in equal 
Times thro’ the Lungs, than thro’ any other 
Part of the Body, and confequently a too vif- 
cid State of it, will fooneft be felt there : Or 
in the Pleura^ where Anatomifts obferve, that 
the Blood has alfo a very free and fliort Cir- 
cuit, by the intercoftal Arteries, and thence 
thro’ the Azygos Vein to the Heart: On 
which Account there being alfo a very plen- 
tiful Flow of Blood into the Pleura^ the Ef- 
feds of its Sizcnefs are frequently iirft felt 
there ; and that oftner on the left than the 
right Side : Probably becaufe the Aorta lay- 
ing on the left Side, the Blood is thence im- 
pelled with greater Force, into the fliorter left, 
than into the longer right intercoftal Arteries J 
Which Inconvenience, as is well known, is 
often greatly rebated by decreafing the Qiian- 
tity of Blood in Bleeding. And thus alfo in 
plethorick, afthmatic and other Cafes, the 
Lungs are often immediately very fenfibly re- 
lieved by abating the Quantity of Blood.
