fiich as I conceive the Minute particle^ of a Body diflblved 
in a MenHruum. 
On this account 'tis I fay, that the forementioned Princi- 
ple of i^^/'^^^/V/'^ is a Uttle defe£tive ; for it confiders not 
the Natural Congruity of tlie Parts of a Liquor, whereby 
theydefire, as't were, to unite and keep together, juft as 
we fee two Drops of Water on a Dry Board being brought 
together do jump and Coalefce, and therefore Liquors Iiave 
an innate power of Refifting a certain degree of force that 
would feperate them \ fuch as I fuppofe the degree of Gra- 
vity, in the moft Minute Particles of a Body diffolved in a 
Menfirmm. 
The forementioned Rule holds true to the moft nice 
Sencein Great. Body s, but in thofe that are by many Milli- 
ons of Divifiaa^ Smaller, it feems to fails. 
This in Ihort is my Conjecture in this matter, which 
Ipropofe, as my Brother did his, with all fubmiffion imagin- 
able, and thereby to give occafion to others to enquire into 
the Gaufes ofthis appearance, rather then to publifli my 
own fentiments as the undoubted folution thereof. 
But this I muft acknowledg, that the Internall motion of 
the parts of a Liquor feems fo very agreable to truth, an4 
^ explicates fo many Ph3t:nomena eafily and plainly, that I 
would not be thought to deny it . Neither would I be 
thought wholy to Reje£t my Brothers folution of this Pro^ 
blem J for certainly that Motion(what foever it is) i;ia Mr^^ 
Brmm , which is able to DilTolve fuch a folid Body as Iron, 
that is, which is able to distiirb the clofe and ftrongCohe- 
iion of the Parts of Iron, may very well beiuppofed fuificient 
to difturb or keep up thefe parts from refting in the Bottom 
of the Vcffcl], wherein the folution was made ; And cer- 
taijniy ao better account can: -poffibly be given of fuch foluti- 
ons , th^n by fuppofing fuch an Inter niill motion in the Parts 
of the MenUrmm infinuating themfelves into the folid 
body, and loofening its Parts. And tho it may be objeftr 
ed^ that in the Parts of Watei: there may be fuppofed as Vio-
