and if further the placental discrimination is 0•62 as found by Bryant and Loutit, then the serum calcium of the mother can be expected to be 0•62/0•82 or 76 per cent that of the new-born. This increased concentration of calcium in tho infant's serum as compared with that of the mother is consistent with Comar's findings in animal experiments 4 , but requires verification in examination of human beings.I thank Dr. Arthur Weinberg for obtaining the blood samples for this work.

Lokal inhibition of tissue respiration with cyanide slightly diminished the increased vascular permeability induced in rabbit skin with B-irradiation (⁰⁰Sr + 99y, 9500 rad). These findings confirm the role of mediators of vascular permeability in the radiation induced increase of permeability as well as the direct vascular radiation damage.
