A few years ago in the book, Die physiologische Entwicklung des Kindes. Vorlesungen ilber funktionelle Padologie (Springer-Verlag, 1959), the then-current state of knowledge in the field of pedology was compiled by pediatricians from the most diverse countries. In contrast to the term "pediatrics," the word "pedo- logy" was used to refer to the physiology of the child, because although the physiological development of the child is intimately associated with disturbances of body functions, both are different from experience with adults. Pedology is more comprehensive than physiology, in that it covers both the physiological and psychological development of the normal child. Favorable response to the above-mentioned book stimulated the project of documenting further progress in pedology at certain intervals, especially by authors who themselves had contributed substantially to these advances. In 1965 and 1968, respectively, two volumes under the title Fortschritte der Pado- logie were published by Springer-Verlag-Berlin-Heidelberg-New York. Whereas up to now the English language was used in only some of the articles, in the present volume all authors present their papers in English.Marburg, Spring 1973 The Editor Contents W.
