"... I had agreed with Russell that those three articles for The Monist should be paid at the rate of three guineas per 1,000 words. I remarked to him that we should probably publish them separately afterwards. So far as I remember the articles were between six and seven thousand words each so that 300 dollars (£60) would pay him for the whole three."

The three articles are under the title "On the Nature of Acquaintance".

Muscio: "I saw him once a long time ago in company with Wittgenstein, who you know has done very good work in logic in cooperation with Russell."
