In 1937 Mr. H. G. Wells was the president of the Section of the British Association on Educational Science. The substance of his address to the session, delivered on Thursday September 2, 1937, is reproduced here because it faithfully if brilliantly reflects the flavour of the British Association in the thirties, because of the historical importance of Wells's ideas on education, and also as a way of recalling that this year is the centenary of Wells's birth.
