Mason, Fellow of Trinity College, Cambridge, whose exact scholarship has been particularly valuable to me.

On another side than that of scholarship I have derived the greatest benefit from the advice of my friend James Beddard, M.B., of Nottingham, who was among the first to help me to realise, and now does not suffer me to forget, what a book ought to be.

The Index of References to the Gospels has also been made for me.
The chapter on Marcion has already appeared, substantially in its present form, as a contribution to the Fortnightly Review.
