ABSTRACT

The work of Miss Barrington and Mr. Pearson is conducted in accordance with well-established principles of statistical investigation, and serves to exhibit the marked influence of heredity as compared with a minor action of environment in determining defects of vision. Doubt is thrown on the theory that school work produces myopia and it is suggested that the increasing number of myopics shown in the higher classes is evidence of a law of growth and selection and not due to environment. The necessity of more careful statistical work, dealing with larger numbers of pupils and covering all classes without selection, is emphasized, but the authors are of opinion that the results of their work show a preponderating influence on the hereditary factor.
