AKo, I cannot but take notice, how fomeMenare 
deceived, that think the Sournefs oiVimgar^ proceeds 
from Eels pricking their Tongues, with their Tails; for 
if this were true, then would fome Vinegar be fiat, becaufe 
there are no Eels in it, or that tliQ Eels are dead in it, 
as is uluall in cold or frofty weather. 
I confidered fome Vinegar, that had Crabs-Eys put 
in it 5 becaufe they are faid, to take away its fourneis. 
If this be true, I concluded, that the above defci ibed Salt 
particles muft be changed, either by increafing the bulk, 
or becoming more ply able and limber,lo as not to pierce 
the Tongue. 
I took feveral! new Glaffes, and put in them fome 
Crabs'Eys , fplit into {mall pieces, leaft the grit that 
comes from them, after they are pounded, fc-ould hinder 
my fight; I found that the long fharp j^/zr^j-, which: 
might be likned to aWeaversShuttIe,were now changed 
mto figures y whofe Bafis was oblong, n^m^ xx^ Pyramu 
dally^likQ^ pointed Diamond; as Num 2 Fig, F. Others 
had their Bafis fquare as Fig. ^Others an irregular 
CJuadrilateral , as Fig. J{, But thefe two laft figures^ I 
fuppofed were accidental, f or want of fufficient matter 
to com pleat, ^nd per feifcthexQ on all fides. Note that 
thegreatnels of thefe particles, and thofe in fimple 
Vinegar^ muft not be compared together ; becaufe thefe 
ar^ drawn by a G/«/f, that Magnified more, then that 
wherewith the others were drawnj for otherwife^ thefe 
would not fo clearly have been difcerned. 
The number of particles was fo great, that ("in a grofs 
computation, j I judged them, to be fix Thbufand in a 
Drop, about the bignefs of two Barly-Corns, But that 
which ! moft wondred at, was, that thefe particles 
here, were almoft all of the fame bignefs ; f a thing I ne- 
ver obferved, in any other Salt before.^ 
I took fome Vinegar out of a Glafs^ that had Crabs* 
iy/ in it, at a time;, before all t\iQ Air-Bubbles wereaf- 
cended i.
