caufe the fudden Jirk of the relaxed Vef- 
fels, in propelling and expelling their rari- 
fied Fluids to the Centre, the Diameters of 
the Veffels will be fuddenly fhortened, and 
the divided Globules of Blood will again 
run together, and in larger Malfes, than 
the contracted capillary Velfels (which are 
conic) can poffibly admit of, or let pafs ; 
but they muft flop, and not only they , but' 
all the Globules behind, in the fame Branch 
from the Cone to the laft Divifion, whofe 
more thin and ferous Juices, will, by the 
ACtion of the furrounding Parts, be driven 
on, but the more globular and grofs will 
flop ; hence are ObftruCtions producing an 
Inflammation. But where the Blood is 
mod rarified, the Veffels weaked, the pro- 
trufive Force lead, and the Contraction 
dronged, and confequently where the In- 
flammation will happen, is impoflible to 
foretel ; hence may it be more or lefs dan-
