title: The avian egg and the retina.
abstract: A mathematical model for study of blood flow has been derived from the avian egg, utilizing the theories of crystallography and photosynthesis. The model is employed to explain the form of the eye and the function of the cells of the human retina, with special reference to colour vision and the pathology of migraine.
