conclusions 



I. The systematic exposure of children to the direct rays 

 of sun regularly brings about healing of the rachitic process 

 in the bones. 



II. The pigmented skin of the negro does not interfere with 

 the therapeutic action of the sun's rays. 



III. The changes in the concentration of calcium and in- 

 organic phosphorus are identical with those which follow the 

 administration of cod liver oil or radiation with the mercury 

 vapor quartz lamp. 



IV. The action of sunlight is as prompt, if not more so, 

 than that of other curative agents.
