Many thanks to all of the responses.
For anyone that's interested, the book is 'The Psychology of Fear and Courage' by Edward Glover (1940) a 1st edition penguin paperback.
The above transcription was written on the back page, and all through the book are annotations of someone's train journey from Banbury to the New Forest complete with excerpts such as 'Eastleigh 4.15 - blind down, air raid in Southampton'. There are also the reader's musings on the text and even statements about the local ARP meetings and the personalities of those who attend.
It's fascinating, being part mystery and part social history, of both the notes relating to the war and following the original reader's train journey. If only I could find out who the well wisher was!
