The effects of inanition and malnutrition upon growth and structure . -Jf"**^ y-r I I.; historical survey of the questions concerning the etiology of rickets has recently been made by Park ('23) and by Vaughan ('23). Human Rickets.—For the present, we are concerned merely with the more general effects of rickets upon the growth of the body as a whole, leaving a consideration of the effects upon the skeleton and other organs for later chapters. The occurrence of fetal rickets has often been claimed, but according to Wieland ('10) it is very doubtful. Huenekens ('17) found premature infants especially susceptible to rickets, and J. H. Hess ('23) gives the characteristics in this class of cases. Rickets in the human species does not ordinarily appear before the latter half of the first year, and is most frequent during the rapid growth period of the first two years. It may occur at any later age, however, and in the adult I it is usually designated as osteomalacia. According to Ruffer ('21), rickets has existed in Egypt since 2,000 , § and probably much earlier. Deformity of the spine and legs (probably rachitic in origin) was described by Soranus as prevalent among Roman children of the first' century, In most civilized countries today rickets is still a very potent factor in stunting growth, produc- ing deformity and lowering resistance to infection (Findlay and Ferguson '18). Kissel ('97) noted a variable degree of rickets in 80 per cent of 2,530 children examined at Moscow; and Schmorl ('09a) found evidence of either active or healed rickets in 345 ( per cent) of 385 children under 5 years of age autopsied at Dresden.
