§ MR. G. DRAGE (Derby)I beg to ask the Secretary of State for the Home Department, whether he will consider the desirability of an official investigation into the cause of miners' nystagmus, and the best means of preventing that disease?
§ SIR MATTHEW WHITE RIDLEYI am not prepared to institute any general inquiry into the causes of miners' nystagmus. I understand that the hon. Member's view is that this disease is frequently caused by defective safety 709 lamps, and if he will bring to my notice any cases of nystagmus which are supposed to be due to this cause, I will have inquiries made. This can be done in the first instance by the Inspector of the District, and if necessary a medical man can be consulted.
