§ Mr. G. HALL
asked the Secretary for Mines the number of coal-miners in South Wales who are incapacitated for work owing to suffering from miners' nystagmus?
§ Lieut.-Colonel LANE-FOX
I regret that this information is not available, but I am sending to the hon. Member a copy of my reply to the hon. Member for Abertillery (Mr. Barker) of 26th March, giving the figures for the country as a whole from 1910 to 1921, with those for 1922 added. I will see what relevant figures I can get for South Wales alone and will 489W communicate further with the hon. Gentleman.
