STATISTICS OF OBSERVATIONS. 81 



the hands and feet were cold. The physical examination was otherwise normal 

 and the Wassermann reaction was negative. During a part of his stay in the 

 hospital, it was impossible to give him the usual number of calories in his food, 

 as, for instance, on November 24, when he received only 90 calories per kilo- 

 gram of body- weight; the temperature at this time was subnormal, being 

 36.1° C. to 36.7° C. (97° F. to 98° F.). On November 13 and 21, when he 

 received about 130 calories and 145 calories respectively, the temperature was 

 normal. When he was discharged on December 27, 1913, he weighed 3.05 

 kilograms. His case was diagnosed as infantile atrophy. He weighed when 

 2 months old 0.8 kilogram less than at birth. His digestion was very weak. 



Subject, G. S. Male; born December 1, 1912; birth-weight, 3.64 kilograms. 

 Since his birth he had been fed on various home modifications of milk, 

 barley water, lime water, and milk sugar. He seemed hungry, cried consider- 

 ably, and did not gain in weight. When he entered the hospital February 12, 

 1913, he was found on physical examination to be a well-developed but poorly 

 nourished infant, with a small amount of subcutaneous fat. He appeared 

 bright and active and had a strong cry. His weight was the same as at birth, 

 whereas at his age (2| months) it should have been 1.5 kilograms more. He 

 was given milk modified to his digestion, with a fuel value of about 100 calories 

 per kilogram of body-weight. Digestion not remarkable. His temperature 

 remained normal. He was considered to be a case of regulation of feeding. 



Subject, J. S. Male; born December 28, 1912; birth-weight, 5 kilograms. 

 For the first 6 weeks he was breast-fed ; subsequently he was given a modi- 

 fication of cow's milk, but vomited after each feeding, cried most of the time, 

 and was very constipated and hungry. He entered the hospital on June 3, 

 1913, at the age of 5 months. On examination he was found to be a small, 

 emaciated infant, with the facies of old age. There was no subcutaneous fat 

 and the skin hung in folds. The muscles were strong but firm. There was 

 a slight rosary, but the physical examination was otherwise normal. He was 

 given modified milk, with a fuel value of approximately 120 to 140 calories 

 per kilogram of body-weight. The temperature was normal during his stay 

 in the hospital. He was an atrophic infant with no definite signs of indiges- 

 tion. His weight on entering the hospital was 4.08 kilograms and on his 

 discharge 4.53 kilograms. This was less than his birth-weight and only half 

 what he should have weighed at his age. 



Subject, P. S. Male; born December 23, 1912; birth- weight unknown. 



He had never been a well infant. On September 20, 1913, he had acute 

 bronchitis. He entered the hospital on November 19, 1913, and had broncho- 

 pneumonia on November 21. Later he had otitis media. In the week pre- 

 ceding the determination of his metabolism, his temperature had been normal 

 and he had gained in weight, although previous to that time he had lost 

 considerable weight. His digestion was also good, and his physical examina- 

 tion was normal. His weight on December 18 was 7 kilograms, this being 

 about 2 kilograms under weight, as the average weight for an infant of his 

 age (12 months) is 9.5 kilograms. 



Subject, H. T. Male; born October 25, 1912; birth- weight unknown. 



This infant was breast-fed from birth and had always been healthy. He 

 was brought to the hospital for weaning and taken into the ward on April 15, 

 1913, to have his metabolism determined. The physical examination was 

 normal, showing that he was a strong, well-developed and well-nourished 

 infant, with a large amount of subcutaneous fat. During his stay in the hos-
