NEW-YORK, Aug. 3.
Among the number of interesting discoveries which have been lately communicated to the public, is the following, which is likely to prove not less useful than it is curious.
It consists of different chemical mixtures (into the composition of which ice enters in no form whatever) by means of which, water or other liquors may be frozen, and the usual phenomena attending natural frost produced at any time of the year in the hottest parts of the world.
The following is one of them, which although it be the least powerful, is nevertheless sufficient for the purpose above mentioned. Mix by degrees, agitating them well together in a convenient glass, or glazed earthen vessel, equal quantities by weight of strong oil of vitriol and water; cool this mixture, (which will be very hot) to the temperature of the air; to sixteen parts of this liquor thus thoroughly mixed and cooled add twenty-one parts (each by weight) of Glauber's salt, perfectly dry and transparent, freshly reduced to very fine powder, stirring the mixture that the salt may dissolve as soon as possible.
It is necessary that Glauber's salt for this purpose be kept unexposed to the air, otherwise it will be converted into a white powder in which state it is unfit for this use.
