INANITION AND MALNUTRITION 



The investigations of Waters upon the growth of steers at various planes of 

 nutrition were continued and extended by Van Ewing and Wells ('14), by 

 Trowbridge, Moulton and Haigh ('18, '19) and by Moulton, Trowbridge and 

 Haigh ('21, '22). The results confirmed those of Waters as to changes in the 

 form and proportions of the body, with additional observations upon the various 

 organs (to be mentioned later). 



A persistent growth in length of very young fasting tadpoles of Ranafusca was 

 recently found by Podhradsky ('23).

In children, Auboyer ('81) ascribed the abnormal growth in length of the 

 extremities sometimes observed during and after certain fevers to the stimula- 

 tion of the epiphyseal cartilages by the febrile toxins. Camerer ('93) noted an 

 apparent increase in length during illness, but in the absence of exact measure- 

 ments concluded that this was an illusion, the length appearing exaggerated by 

 the emaciated condition. In 1905, however, Camerer, Jr. observed a case of 

 chronic gastrointestinal trouble in a child beginning at 9 months and extending 

 U P to 5 years of age. There was marked retardation in weight, but normal
