The resulting solid was termed a cryohydrate by F. Guthrie, but it is really an intimate mixture of two kinds of crystals, and not a chemical compound or hydrate containing the constituents in chemically equivalent proportions.

From Project Gutenberg

The lowest temperature attainable by means of a freezing mixture is the temperature of the F.P. of the corresponding cryohydrate.

From Project Gutenberg

The alloy corresponding to the cryohydrate, possessing the lowest melting point, is called the eutectic alloy, as it is most easily cast and worked.

From Project Gutenberg

But if we throw into it a crystal of a previous crop of cryohydrate, then nothing but the cryohydrate separates.

From Project Gutenberg

But at length a point is reached at which the temperature ceases to fall until the whole of the remaining mother-liquor has solidified, with the production of a compound called a cryohydrate,3 which possesses physical properties different from those of either the ice or the salt from which it is formed.
