When I had taken them -out of the premention d Mix- 
ture, (which was at fomething more than an Hours time 
from their firft putting in)I pour’d from them the Unfro- 
zen Water, which gave»me the Liberty of difcoverinf^' the 
various forms ‘the new madelce had (hot it felf into.fhat 
Glafs which contain’d the Purg’d Yfater, appearino- all 
over the Sides and upper part of it, to* the very Neck^ 
of divers Figures, much refembling thole of Salts. The 
Bottom part of it ^ c, difcover’d it felf to be feemingly fo- 
lid, but whitilh, as if it was lull of very minute inter- 
fperh: ^^acuities; but not like thofe Cavities, which are 
very obfervable in the Freezing of Common Water • 
and what was very notable, at the Bottom of the other 
Glafs they appear’d in great Numbers, of a longilhl 
Form, feemingly pointing all round from the Circum- 
ference to the Centre of it. There were none of thofe 
premention’d Salt-like Figures bn the Tides* of this, as 
the other, but it was almoft clear frOm any Adherence 
of Ice, faving towards the upper part near tlie Neck, 
where a little had faften’d it felf with thofe longifh 
Bubbles, pointing from that part downwards, inciinino; 
to the Centre. From all which ] cannot but conclude^^ 
that the Ice produc’d from the Water purg’d of Air, wa5i 
equally augmented in its Bulk to the Quantity of VVater 
from which it was produc’d, as that which proceeded 
from the- Frozen Common Water- for had the Glalles 
been of an equal Content, I fee iToreafon to doubt, but 
the Water would have been equally Frozen in both, and 
the Afcent of the unfrozen part bf'them would iiavc 
been much the fame in their Tubes. But if there be 
any difference, the Water purg’d of Air Teems todaini.^ 
the ealieft Difpofition to be Frozen.-. •
