This paper represents the analysis of the components of refraction across seventy-one Eskimo families consisting of thirty, first generation or grandparents, forty-one, second generation or parents and 258 generic children. Both husbands and wives are included in the first and second generations. The results indicate that the initial size and component relationships within the one-two year old eye are probably inherited along with high hypermetropia and corneal power in older children and adults. There is no evidence that any of the other components are inherited.
