    CHAPTER IV The Immediate Effect of Antenatal Patliology ; The Antenatal Factor in Neonatal Pathology. The Neonatal Period of Life ; Physiology of Neonatal Life ; Physiological Traumatism of Birth, including the Pressure Effects and the Separation Effects; Physiological Readjustment at Birth, and its Influence uiDon the Characters of the Maladies of the New-born Infant; Anatomical Eeadjustment; The Antenatal Factor and its Influence upon Neonatal Pathological Processes. As has been pointed out in the preceding chapter, the effect which antenatal morbid states exert upon gynecological disorders is a postponed one and is not manifested for many years, during which the genital organs and their abnormal or normal potentialities are dor- mant. In this and in the following chapters fall to be considered the immediate effects of antenatal pathological conditions, those which have a bearing upon the characters of the diseases of the new-born infant. On the dividing line between Antenatal and Postnatal Pathology lies Neonatal Pathology, a sort of unexplored territory, a No Man's Land, liable, however, to incursions from both sides, those of the weaker kind coming over the antenatal boundary. Between the surgical injuries and maladies of the life that is after birth, and the diseases and deformities of the foetus and embryo, are situated the morbid conditions of the new-born infant, conditions which interest both the pediatrist and the obstetrician. Investigation of them has indeed gone on from both the pediatric and the obstetric standpoint, but with more activity, it has seemed, from the former than from the latter. Nevertheless, it is well to bear in mind that the maladies of the new- born have relations, not only with the diseases which occur later, but also with the pathological states which have happened earlier in life. Just as neonatal life is the link between postnatal and antenatal life, so Neonatal Pathology is the link between Postnatal and Antenatal Pathology. It offers problems for solution which require that we take into account both the conditions which precede and those which follow birth; its study, further, is helpful in throwing light on them both. That neonatal morbid states offer peculiarities of a very marked kind hardly calls for proof. It need only be pointed out that, in order to emphasise these peculiarities, a nomenclature has come into use which adds to the name of the disease the word neo- natorum. In this way the terms cephalhaematoma neonatorum, pem- phigus neonatorum, icterus neonatorum, mehena neonatorum, 3
