2jo Mr . Cavendish’s Account of fome 
became full of white fpots f , and grew thick by the time it 
arrived at its greateft degree of cold. After ftanding fome 
hours, the mixture rofe to the temperature of - 39 0 , and was 
grown clear, but yet was not limpid, but of the confidence of 
lyrup. No cold was produced by adding fnow to it in that 
date, though it appeared that its point of aqueous congelation 
was at lead 6 degrees lower than its temperature at that time -f* ; 
which feems to (hew that fpirit of wine has fcarce any power 
of diflolving fnow when it wants even 6 degrees of its point of 
aqueous congelation, and therefore is another indance that 
fnow is diffolved much lefs readily by fpirit of wine than by 
the nitrous and vitriolic acids. 
32. In trying the other part of the diluted fpirits, the cold 
produced was only — 47°!, the cold fet out with being — 37°. 
33. It appeared by the diluted fpirit of wineN° 143. which 
on December 12 froze by the natural cold of the atmofphere, 
and was treated in the fame manner as the diluted fpirit of 
nitre, that when highly redtified fpirit of wine, fuch as N° 8. 
is diluted with i T t its weight of water, its point of aqueous 
congelation will be at - 21 0 . The congealed part of the fpirit 
was white like diluted milk, and even the decanted part, which 
was full of thin films of ice, had a milky hue. The fluid 
part was ftronger than the reft, and no increafe of cold was 
produced by adding fnow to fome of it, both of which are 
marks of aqueous congelation. 
* This was not the cafe during the above-mentioned dilution of the fpirits $ 
but the cold was 16 degrees lefs in that experiment than in this. 
f On account of the dilution which the fpirits fuffered by the melting of the 
fnow which remained undiftolved at the time of the greateft cold, its point of 
aqueous congelation was no longer fo low as —56°; but it ftill was not lefs than 
~~45l, as in the evening it was found at that temperature, without much con- 
gealed matter in it.
