be prepared to think of crystallisation as having taken
place from solvents which are solid at the ordinary

little of one metal dissolved in another, is quite analogous
to a solution of a salt in water, although the alloy must
be kept at a very much higher temperature, if it is to
remain in the liquid condition. Now just as the salt
crystallises out from its water solution, so the one metal
