* Wort, it both excites fooner, and carries 
on more regularly that inteftine Motion 
caufed by the Occurfions and Collifions of 
Particles of different Gravities, whereby the 
fpirituous Part will ftill be ftriving to mount 
up to the Top, and the vifcid ones, on the 
contrary, retard fuch an Afcent, and hinder 
the Evaporation and Lofs of the Spirits. 
From thefe two co-operating Caufes, the 
Particles extracted from the Grain, will, by 
frequent Intercourfes and Collifions, be fo 
broken, as continually to increafe the more 
fubtile and fpirituous Parts, until all that 
is poflible to be made fo by Attrition, are 
difentangled from their Vifcidities. This 
inteftine Motion of the Liquor is both vi- 
. iible and audible 5 and this Action and At- 
trition of its Parts, are difcoverable from the 
Heat they raife in it, and the Froth they 
fend up to the Surface. And that this Ac- 
tion is what breaks the Vifcidities, and fets 
at liberty the fubtiler and finer Parts, or 
breaks 
* I confuler Wort as a heterogeneous Fluid, whofe Parts 
mult neceliarily interchange their Pofitions, till each has ob- 
tained fuch an Elevation, as correfponds to its proper Gra- 
vity. But this natural Difpofition of thefe heterogeneous 
Parts to interchange their Places, till each obtains its proper 
Gravity, being not fuffrcient to break and feparate thefe Vif- 
cidities, which entangle the fpirituous Parts, and to prevent 
their exhaling at the Surface ; it is neceflary that fome alrea- 
dy fermented Subftance be added to, and mixed with it, that 
may promote a regular, fpeedy, inteftine Motion.
