in England. In particular, I am grateful for the assistance provided by Dr Robert
McKeever, the erstwhile Head of School. As usual, I am entirely dependent upon
the outstanding skill and dedication of my manuscript preparation person, Barbara
Watts, who truly is an inspiration. Her speed on the keyboard, her ability to read my
handwriting and her readiness to meet unreasonable deadlines are beyond praise.
Last, but not least, my ever-suffering family deserve the most sincere thanks for
tolerating, usually with good humour, my protracted distraction with the challenges
of book creation. Valerie and TJ, I could not have done it without you. That may serve
to share some of the blame!
