1) The author measured the threshold wave length of the photoelectric effect of the citrated human blood. 2) The experiments gave the following results :-The threshold wave length of the citrated blood of healthy persons is longer than 3150 Å and shorter than 4300 Å in 10 cases out of 11 and in 1 case longer than 4300 Å; viz. in every case it is longer than 3150 Å. On the contrary, however, the threshold wave length of the citratdd blood of the patients with pulmonary tuberculosis is longer than 3150 Å and shorter than 4300 Å in 12 cases out of 15, and in 3 cases longer than 2500 Å and shorter than 3150 Å. It is considerable that the quantity of albumin in blood may influence the threshold wave length of the photoelectric effect of the citrated human blood, because albumin is the only photoelectrically active substance by long visible rays among the ingredients of blood. This reasoning is proved by the fact that the threshold wave length of the wet citrated human blood, measured soon after the arrangement, is longer than 2000 Å and shorter than 2500 Å, because the smaller the humidity of albumin, the longer the threshold wave length of it as previously reported.
