Not illustrated. 1905 edition. Excerpt: ...and even after it is fully ossified the whole bone is at first remarkable for its shortness. The palate hence requires an additional period to develop after ossification. The complicated relations of the palate to the turbinated and maxillary bones, both under stress from the law of economy of growth as varying structures, place it under varying conditions of nutriment, expressed either in excess or in the deficiency shown in cleft palate. The fact that the palate is permanent compared with the turbinates and the rest of the maxillary bones, indicates that, aided by its early ossification tendencies, it tends to survive in the struggle for assimilable nutriment. Heredity of long standing, however, sometimes so affects early development of the palate as to give the other two bones an advantage. This occurs where the pre-coneeptional vitality of the mother is lowered, or where the first two months after conception are periods of extreme maternal strain. Paternal vitality when lowered affects the early conceptional period. This, to some extent involves an influence on maternal vitality, since, as has been repeatedly shown, chiefly after maternal breakdown does paternal defect show itself. In Mongoloid idiocy, as W. A. Hammond has shown, early pregnancies when the mother is healthy are free from such offspring, but later births are of this type. To such an extent is this maternal vitality in evidence that even syphilis may not arrest development, Thus, as in a case reported by Engel, the husband may be infected during the second month of his wife's pregnancy and immediately infect her. A hearty boy is born with copper-colored eruption about the anus and later coryza. These symptoms disappear under specific treatment, not to return. The child
