it, by juft warming the Tides of it by a Fire. I found then 
by pricking a piece of Wire into the dark part of it, 
the Red Liquor immediately fucceeded thro" the Hole I 
had made, leemingly as pure and as abftraded from any 
Mixture of Water, as it was before it was put into it. 
This Red Liquor I found to be fomething fpecifically 
lieavier than Common Water ; which .makes me won- 
der, why the Figure it made on its retiring, was not ra- 
ther the reverfe to what it appear’d : For 1 Ihouid think 
it reaibnable to exped, that the upper part, which was 
the broadeft, fliould, by its own weight, alter or reverfe 
the Pofition of the Figure. Another thing very remark- 
able, was, that this retir’d Liquid, as it Teem’d to keep 
an equal diftance from the Tides of the Glafs, To did it 
‘from the bottom and top of it; which upon repeated 
Tryals anfwer*d the Tame. 
I likewife mixt Tome Common Water with a ftrong 
Purple Liquor, made from Logwood, boyl’d in Water, ^ 
.in which Tome Allom had been diffolv’d. A little of 
this would give a ftrong Tin£fure to a pretty Quantity 
of fair Water ; and when expos’d to Freeze, would re- 
tire towards the Middle, leaving thefirft Frozen Water 
of a very .pale Purple, in comparifonto the middle part ; 
which when I had taken out of the Glafs that contain’d 
;it, and broke it, I found ItWas' Frozen through, but 
of To dark a Colour in the middle, that it came neai' 
a Black.
