B. The age of the mother at the time of parturition does not show any regular influence on the size and weight of the child. It has a very sensible influence on the frequency of miscarriages and of stillbirths; this increases with the increase in age. The age of the mother at the time of marriage exercises a decisive influence upon the vitality of the offspring: the greater the age of the mother at the time of marriage the less will be the vitality of the children. The age of the father at the birth of his child has some influence on the number of stillbirths among his children. This influence--at any rate above a given age--increases with the increase in the father's age. It can neither be disproved nor affirmed that the age of the father at the time of marriage has an influence upon the vitality of the children; it is certain, however, that if any influence of that kind exists it is much less intense than that exercised by the age of the mother. There has also been an enquiry as to the effect upon the characters of the offspring exerted by (1) order of birth; (2) difference in age of the parents; and (3) the age of the woman at the first menstruation. C. Persons who die at a more advanced age have children in greater number and endowed with greater length of life. For some classes of the unfit (mad, consumptives, suicides) it can be proved beyond question that the number of children born is less and their mortality greater than among married people generally. Those who die of heart disease or of cancer show a number of children slightly higher than the general average of married persons; but that can be attributed to the fact that their age at death is greater than the average age at death of married people. MATERNITY STATISTICS OF THE STATE OF RHODE ISLAND, STATE CENSUS OF 1905. (Abstract.) By Frederick L. Hoffman, LL.D., F.S.S., _Statistician of the Prudential Insurance Company of America._ As a contribution to the practical study of eugenics the decennial maternity statistics of Rhode Island are of exceptional interest and importance. In 1905, of 36,766 native-born married women 26,329 (71.6%) were mothers, and 10,477 (28.4%) childless. Of 32,960 foreign-born married women 27,207 (82.5%) were mothers, and 5,753 (17.5%) childless. Contrasting these percentages, the fact requires only to be stated to emphasize its profound and far-reaching social as well as political significance. Considered with reference to religious belief, 72.7% of Protestant and 80.3% of Roman Catholic married women were mothers. Of married women of Jewish faith 88.0% were mothers. At ages 25-34, the proportion of native-born mothers having only one child was 35.1%, against 22.6% for the foreign-born; the proportion of mothers having from six to ten children was 6.8% for the native-born, against 12.9% for the foreign-born. At all ages a similar disproportion is apparent.
