"Don't talk nonsense. You're very much alive. You are in the laboratory, blundering about. You've just smashed a new electrometer. I don't envy you when Boyce arrives." He stared away from me towards the diagrams of cryohydrates. "I must be deaf," said he. "They've fired a gun, for there goes the puff of smoke, and I never heard a sound."
It is of interest to notice that from our knowledge of the cryohydrates it becomes possible to predict the existence, composition, and temperature of solidification of a eutectic alloy, if we are previously furnished with the melting-points of mixtures of the substances in question. Or, in other cases, we may predict from the curve of melting-points that no eutectic alloy is possible.
This is due largely to the fact that eutectic mixtures were not known, as equivalent proportions of various salts have been employed, while eutectic mixtures are seldom found to possess any simple arithmetical molecular relationship between their constituents. Eutectic salt alloys closely resemble cryohydrates in behavior.
Following in the natural divisions adopted by Dr. Guthrie, we may consider eutexia in three aspects: I. CRYOHYDRATES.

Two molecules of the monohydrochloride and one molecule of the dihydrochloride form a mixture which melts at about 20°. Although many fusible alloys have been long known, I believe no true eutectic metallic alloy had been studied until Dr. Guthrie worked at the subject, employing the same methods as with his cryohydrates.
