That a reduction in the amount of soft tissues results from undernutrition is well known. The bony skeleton, however, is often looked on as being relatively fixed hereditarily; indeed, the body proportions are widely used by the anthropologist as an index of racial origin. That this concept is erroneous was shown in 1912 by Boas,1 who demonstrated a change in the cephalic index of the offspring of immigrants to America. More recently it was shown that undernutrition in infants results in a change in the proportions of the external dimensions (measured from bony points), undernourished infants becoming more "linear" than well nourished infants of the same racial origin and from the same social environment.2
In the present study the influence of undernutrition on the configuration, relations and texture of the ulna and radius was studied. The infants used in this study have been described in the two preceding
