conducive to sleep under the circumstances. As a rule, the child 

 slept perfectly the first hour and several times slept throughout 

 both respiration periods. 



A graphic record of the pulse was obtained from a blood pres- 

 sure cuff on the thigh and a record of the respirations from a 

 small pneumograph placed about the chest. The pressure in the 

 cuff was kept well below the diastolic pressure and did not interfere 

 either with the circulation in the leg or with the repose of the child. 

 These recording devices served also to record grosser movements 

 when the child moved any part of the body or cried. 



Comparing only the best sleeping periods it was found that 

 the metabolism in different children was much more nearly pro- 

 portional to the weight than to the surface area and when the 

 weight was first multiplied by the specific gravity the agreement 

 was even better.

One atrophic child was in the last stages of marasmus when 

 the observations were made and gave a much lower metabolism 

 than the others. One normal child was very nervous and failed 

 to sleep perfectly. These two are not included in the table.
