The special interest for metallurgists of the phenomenon described in the title of this paper, particularly owing to the help it gives towards understanding the still rather obscure nature of the causes of hardening itself, encouraged the authors to carry out further work on lines suggested by the results of our previous experiments. The latter have been recorded in a previous paper, which itself resulted from a still earlier paper by one of us, in which the original discovery of the phenomenon was recorded. This further work has added appreciably to our knowledge of the phenomenon and at the same time led to the discovery that, under certain conditions of quenching in which hardening does not take place, absorption instead of evolution of heat takes place.
