While Dr Rosenhain in the lecture already referred to takes as an instance the case of a series of alloys which is being studied by an investigator interested mainly in theoretical metallurgy; he works with pure metals or metals as nearly pure as he can get them, and finds that one alloy of his series has some specially noteworthy properties.
