76 GASEOUS METABOLISM OF INFANTS. 



pital was 4.15 kilograms; on June 1,4.48 kilograms; June 12, 4.48 kilograms; 

 and on June 18, 4.68 kilograms. Since the average weight for 4 months is 6.25 

 kilograms, he was about 1.75 kilograms under weight. 



Subject, R. L. Male; born at full term Aug. 14, 1912; birth-weight, 2.27 kg. 



He entered the hospital on February 24, 1913, and an operation was per- 

 formed for hare lip and cleft palate on March 12. The temperature became 

 elevated after the operation and on the 16th a typical measles rash appeared. 

 The temperature dropped to normal on March 22. He was discharged from 

 the hospital on March 27. On April 5 he again entered the hospital with a 

 high fever, a right upper lobar pneumonia, and infected ears. The tempera- 

 ture dropped to normal on April 19 and remained there until April 26, when 

 he had pneumonia for a second time, which continued 8 days. On May 6 a 

 double paracentesis was again necessary and from that time on there was no 

 elevation of temperature. He was a large, well-developed, and well-nourished 

 infant, with normal digestion. On April 15 he weighed 7.60 kilograms, while 

 on May 16 he weighed 7.30 kilograms. At the age of 8 months, therefore, 

 his weight was 0.47 kilogram less than the average for that age; on May 16, 

 when he was 9 months old, he had lost weight and was about 1 kilogram below 

 the average weight. On the other hand, as he was 1 kilogram or more under 

 weight at birth, he was a little over the weight which would be expected with 

 normal development. 



Subject, D. M. Male; born April 24, 1912; birth-weight, 3.00 kilograms. 



This infant was prematurely born at 8£ months. He was breast-fed for the 

 first 5 weeks and subsequently fed on various modifications of milk, malted 

 milk, and condensed milk. During November, 1912, he gained practically 

 no weight and had frequent colds and pertussis. On February 24 he was 

 brought to the Out-Patient Department of the hospital with a double otitis 

 media. Later he had chicken pox. He entered the hospital when he was 11 

 months old (March 25, 1913). At that time he was found to be a fairly 

 developed and nourished infant, with a small amount of subcutaneous fat 

 and soft muscles. He was unable to sit up without support, the back showing 

 a marked curve of weakness. The head was square, with a flat top and promi- 

 nent parietal eminences. There was a slight rosary, but no enlargement of 

 the epiphyses. The physical examination was otherwise normal. Despite 

 the infected ear, the temperature did not rise higher than 37.78° C. (100° F.) 

 during his stay in the hospital. He was given milk modified to suit his diges- 

 tion, with a fuel value of about 140 calories per kilogram of body-weight. 

 During the first few days he did not take the food from the bottle well, but 

 after he had become accustomed to his surroundings, he gained in both weight 

 and appearance, the gain in his general condition being much more than the 

 weight indicated. When he entered the hospital, he weighed 5.20 kilograms; 

 this weight fell to 5.10 kilograms on March 29, after which there was a gain 

 until he was discharged in April, when he weighed 5.23 kilograms. He was 

 about 4 kilograms below the average weight for his age, and about 3.6 kilo- 

 grams below what he would have weighed had he gained in the usual manner. 



Subject, F. M. Male; born September 13, 1912; birth-weight unknown. 



His past history was unknown. When he entered the hospital on January 

 16, 1913, he had congenital syphilis, with a positive Wassermann reaction. 

 The general physical examination was normal except that he was under weight, 

 weighing only 4 kilograms, while the average weight for an infant of this age 

 (4 months) is 6.25 kilograms. His temperature and digestion were normal.
