Above all, it is to my husband that I owe my deepest thanks. At times, when intensely absorbed by a new idea, I would enthusiastically jot it down in an English that was not very English. His harshest criticism then would be, "Stop a minute-your English is getting just a little too eccentric!" There was never criticism without advice; there was always that extraordinary feeling of good will which is constantly present in him and of which, on this occasion, he gave with particular abundance.
