and Colonel Barrett had early in 1917 sent me to London the following
tremendously valuable letter of advice and warning:--

"I suppose my instinct is rather more in the moral direction than
many people, but I recognise, as you will see from these articles
(published by _Lancet_), that it is by direct prophylaxis, and
