Excerpt from Research and Statistics Of course, other influences have been at work. Not all who took the doctor's degree cared to teach in college or university. Not a few have engaged in special research work, and in commercial enterprises. The large number of chemists not connected apparently with educational institutions would seem to point in this direction. It is doubtful, however, if 95 per cent. Of the 899 engaged in higher educational work would be from the sixteen institutions mentioned in Section III., unless a real selective principle were at work.
