§ 62. Mr. Hastingsasked the Minister of Health what evidence he has that the lower incidence of poliomyelitis in Wales in the last few years is associated with the relative absence of main line railways in the Principality, and that cases of poliomyelitis are more frequent in the vicinity of areas in which crude untreated sewage is deposited on railway lines.
§ Mr. R. ThompsonI know of no evidence to indicate that poliomyelitis incidence is related to the existence of main line railways.
