§ Mr. ISAAC FOOT
Statistics are available for the past few years of the number of cases of nystagmus in Yorkshire reported to the certifying surgeons under the Workmen's Compensation Act. These figures, which I will send to my hon. Friend, show a decrease since 1925 but with some fluctuation. The principal measures in hand for the prevention and cure of nystagmus are those to secure improved lighting in mines and an investigation under the auspices of the Medical Research Council.
