CHANGES IN THE NaBrO-NITROGEN CONTENT OF SWEAT

The nitrogen content of sweat seems to vary with changes in the rate of sweating. Observing the total or principal nitrogen of sweat, most investigators (Zuntz and Schumburg (15), Schwenkenbecher and Spitta (11), Riggs (10), Kittsteiner (6), Viale (13), Dill et al. (3), and Araki and Ando (1)) noticed that the nitrogen concentration more or less decreased when the amount of sweat discharged per unit of time increased or when sweating lasted longer. With the palmar sweat, Lobitz and Osterberg (8) also obtained similar results. In contrast to this, Barney (2) and Talbert et al. (12) failed to find this relationship between the nitrogen and the rate of sweating. Recently Mitchell and Hamilton (9) have stated that under conditions of profuse, as compared with minimal, sweating, the concentration of nitrogen increases. The views on this problem so dissenting, it will be worthy of reporting the experiments •õ which were made by the author long time ago and have not yet been published in detail.
