Standing corrected

From Mrs Margaret Thompson Sir: In Christopher Booker's Christmas Quiz, question 2, may point out that Martin and Gilbert Ryle are not brothers — they are nephew an uncle, I have been mildy surprised that no one has pointed this out, but as there has been no correction published, I assume that it has gone unremarked.

I enjoy your excellent paper very much.
