a Viol, pouring upon it a Pint and half of DiOilIeS Vine- 
f^ar, (haking it well together. This Compofition will be 
lb very Cold^ that a man can hardly hold the Veflel in his 
hands in Summer. And it chanced that as Monfieur Horn- 
berg was making this mixture, that the Subjeft froze. 
We fee in this Experiment a Cold yet greater than that . 
inthe Diflblution of 0^/ u4m^;//^i: alonein Common Wa- 
ter. And this Cold is caufed by the Corrofive Sublimate, 
which alone is not at all, or at leaft very little Diffoluble • 
in Diftilled Vinegar. So that the fluid parts of the diftil- 
led Vinegar having quickly penetrated the Parts of the - 
Sal Armoniac^ and having already loft a great deal of their 
Motion,engagrng afterwards in the Pores of a Body which 
they could not Drffblve, and having Aftion not more thari 
enough for that, they do there lofe that little Aftivity 
which they hadr They coagulate there, if not at ail, at 
leaft the greatcft part : and this want of Aftion is the caufe 
of that great Cold which we perceive there. 
Till now, I have only confidered Simple cold DifTolu- 
tions of Salts, in v/hich there is no Augmentation of a 
fenfible Motion 5 Let ns now pais to the Diflblurions of 
tlie fecond Clafs, which are the cold Ferments, in which 
the Cold appears as a Confeqaence of the Agitation of the 
parrs of the Liquor. 
E>ip^ivgtiom of order tofhew the Reafon of Cold Ferments, I owfi 
coidBments, PhyficiansJ that Heat and Cold in Liquors are 
'neither more nor Itfs than Motion in the little parts of 
thefe Liqiicrs, caufed by the cohtinual current of the Sub- 
til Matter in the Sp?xes v/hich thefe Particks do leave 
between them. And I affinn, that every time this Motion 
isdimim'fbed, and when the Courie of the Subtle Matter is 
interrupted, the Liquor appears lefs Hot or more Cold. 
This being fuppofc^dj if we, do attend to that which 
happens in Cold Fermentations, we (hall obferve cn the 
one hand for the moft part, %;ery confiderable Coagulati- 
ons, and a very fenfible Thickening of the Liquors: on
