Detailed studies as to the effect of city life on the human stock remain to be made. On the basis of the material now available, however, fruitful avenues of research are opened, and certain tentative conclusions may be entertained. 1. The changes incident to city life in the birth, death, and marriage rates of the population are noticeable on the basis of statistics. These phenomena permit of sociological interpretation and analysis. The difference between the urban and the rural span of life offers a similar problem to the investigator. The proportions of the human scrap-heap and its social consequences in the city have been recognized as an important phase of urban existence. Bailey, W.
