This volume is one of a series of monographs on pediatric subjects. Marcel Metzger and André Héraux present a clinical review of the physiology and hygiene of the new-born infant, the methods of feeding, dressing and bathing. There is a brief discussion of the initial loss of weight, idiopathic icterus and genital changes in the normal new-born infant.
