McClure and Sauer1 emphasized the fact that in the study of the relation of summer heat to infant mortality the heat regulatory power of the infant has not received its due consideration. It is evident that a number of factors are at work to maintain a proper heat balance; on the one side such as influence the heat production, on the other such as determine its elimination. We are indebted to Rubner2 and his co-workers for the most important data about the influence of clothing on heat loss. At moderate room temperature a certain amount of clothing reduced the heat loss by conduction and radiation to one-third of the loss through the bare skin. With a temperature of 37 C. the interference with the heat loss may be so great as to cause serious disturbances. This is in the adult who has at his disposal the potent heat
