and Talbot and Murlin and Hoobler shows that the normal, 

 recently-fed, sleeping infant produces about two and a half 

 calories per kilogram and hour. With but two exceptions (out 

 of 48) the underweight and atrophic infants produce more than 

 this and the overweight infants produce less. It is suggested, 

 therefore, that for practical purposes two and one half calories 

 per kilogram and hour or sixty (in round numbers) calories per 

 kilogram and twenty-four hours may be regarded as the average 

 normal heat production of sleeping infants within this range.

Meeh's 1 formula K WT 2J3 is accurate in principle only when 

 applied to individuals of differing weights but of similar body 

 form. 



The surface area of five adults of widely different weights 

 and forms was measured by the following method. The subject 

 was dressed in a tight fitting suit of union underwear, the hands 

 were covered with cotton gloves, the feet with socks and the head 

 with a tight fitting bag of woven cotton material. The gloves 

 were then covered with melted paraffin and over the rest of the 

 surface strips of paper were pasted in such a manner that a stiff 

 mould of the body was formed. This was then cut in small 

 pieces which would lie flat. Patterns of these pieces were made 

 by printing them on photographic paper of known area and 

 weight. These patterns were then cut out and weighed and the 

 surface areas of the various parts of body calculated. 



Many linear measurements of the subject were taken and an 

 effort made to find the length and average breadth of each part 

 of the body. After numerous trials characteristic measurements 

 of length and breadth were chosen. The products of the length 

 and breadth when divided into the surface area as actually deter-
