olism was affected (1) by the tide of the blood between the surface and the 

 interior of the body, and (-2) by the? stimulation of the peripheral vaso- 

 niotor and sensory nerves. The Russian investigators in their five cases 

 observed a considerable decrease in nitrogen retention during the bathing 

 periods, which was not a result of poorer utilization of the food. In three 

 cases in which a final period was also possible nitrogen retention was seen

 possibility that all children may not react to the "cure" in this way indi- 

 cates that the use of sool baths in pediatrics must rest on a scientific founda- 

 tion. 



Blood pressure measurements made by Loewy and others in the sea- 

 bathing experiments mentioned above showed a pronounced rise in systolic 

 pressure, scarcely any change in the diastolic, with the result that pulse 

 pressure reached high levels. There was usually also an increase in pulse 

 late. Within five minutes after the bath these phenomena had practically
