Dear Unwin,

Yes, I have reserved the right to include my Lecture on Physics and Experience1 in a future volume. Publication by the University Press, in the first instance, is a condition of the Lectureship.

By the way, I shall be grateful if you will postpone my next royalty cheque until after April 5th.

Yours sincerely,
<signed> Bertrand Russell.
