STATISTICS OF OBSERVATIONS. 75 



Subject, E. K. Male; born at full term July 13, 1912; birth-weight unknown. 

 He was breast-fed for 2 months; subsequently he was given modified milk, 

 and more recently was fed from the family table. He had never been well 

 and when brought to the hospital on November 29, 1913, he was found to have 

 broncho-pneumonia and rachitis. The metabolism was determined a week 

 after he had recovered from the pneumonia. He was physically a fairly well- 

 developed and nourished infant with a moderate amount of subcutaneous fat. 

 When his metabolism was determined, his weight was only 8.03 kilograms, 

 which is the average weight for an infant of 8 months, so that for an infant of 

 17 months he was very much under weight. 



Subject, F. K. Male; born October 4, 1912; birth-weight, 3.54 kilograms. 

 For the first 3 months he was fed at the breast; he vomited considerably, 

 was cross and fretful, and did not gain in weight. He was then weaned, and 

 at first given modified milk, and later condensed milk, but without improve- 

 ment, as he continued to vomit and to pass 6 to 8 loose green stools a day. 

 He entered the hospital on May 1, 1913, at the age of 7 months. At that time 

 he was a fairly developed and nourished infant, with a considerable amount of 

 subcutaneous fat and firm muscles. The physical examination was normal. 

 He was fed with modified milk having a caloric value of about 140 calories per 

 kilogram of body- weight. His digestion and temperature were normal; he 

 did not vomit during his stay in the hospital. His weight was 5.65 kilograms 

 when he entered the hospital and 5.75 kilograms at the time of his discharge 

 on May 11. He was about 1.5 kilograms lighter than the average for his age, 

 but was otherwise perfectly normal. 



Subject, A. L. Female; born at full term Mar. 2, 1913, birth-weight, 3.64 kg. 

 Previous to entering the hospital, she had been fed at the breast, but had 

 been given supplementary feedings of a proprietary food and milk for a short 

 time. She had always vomited more or less after the feedings and had recently 

 been losing weight. Her weight on entering the hospital June 5, 1913, was 3.10 

 kilograms. The physical examination showed her to be a poorly developed, 

 poorly nourished, and emaciated infant, with almost no subcutaneous fat. 

 All of the peripheral lymph glands were slightly enlarged and there was a 

 slight rosary. The other organs were normal. She was given a diet of modi- 

 fied milk during her stay of 6 weeks in the hospital; on her discharge she 

 weighed 3.20 kilograms. The hospital diagnosis was " regulation of feeding." 

 Since the average weight at 4 months is 6.25 kilograms and the expected weight 

 would be essentially the same, she was about 3 kilograms under weight when 

 discharged from the hospital. 



Subject, E. L. Male; born January 19, 1913, of syphilitic parents; birth- 

 weight unknown. 

 This infant was breast-fed for 1 month, then fed on modified milk, but was 

 not satisfied with the food and did not gain in weight. He entered the hospital 

 on May 15, 1913, at the age of 4 months. When examined he was found to be 

 a rather small, fairly nourished infant, that lay quietly in the nurse's lap. He 

 could not hold his head up. The skin was lax, with small amounts of sub- 

 cutaneous fat. The physical examination was normal except that the edge 

 of the spleen was felt just below the costal margin. The Wassermann test of 

 the blood on May 20 was negative. He was fed with modified milk supplying 

 approximately 120 calories per kilogram of body-weight. The temperature 

 was normal. He had a chronic otitis media which required paracentesis five 

 times while he was in the hospital. Any digestive disturbance during his stay 

 was probably secondary to the infected ears. His weight on entering the hos-
