This paper gives some results of experiments on indentation hardness, which were carried out under especially light loads. The contents of these results a redivided into the following two parts. One represents the hardness obtained by the measurment of the depth of indentation and the other is of that obtained by the measurement of the diameter of indentation. From these results, it may be said that the hardness number takes under light load compression a value considerably smaller than that of ordinary load compression and the formula P=ah+bh^n assumed by the auther may be applicable in such a case since it coincides closely with the experimental data. The value of index n in the above formula is, in all cases, less than 2 and may be taken ⪈3/2 for light load.
