The School of Economic Science at rr, Suffolk Street, has

posters in railway and Underground stations advertising a course in basic economics ; so I rang them up. " This is the School of Economics," said a female voice. I said I had thought that it was the School of Economic Science. The female voice agreed that it was, and offered a course of twelve evening lessons for a guinea. And who, I asked, were the lecturers ? " We don't divulge their identities until after the course has started," said the voice, thus adding to the com- plex and fascinating riddles of an inexact science one more enigma, challenging, mysterious, but not (if you can stump up a guinea) insoluble.
