_Francis Walkinghame._--Your correspondent's mention of my _Arithmetical
Books_ (Vol. v., p. 392.) reminds me of a Query which I made in it, and
which has never obtained the slightest answer--Who was Francis
Walkinghame, and when was his work on arithmetic first published? The
earliest edition I know of is the twenty-third, in 1787; but I am told,
on good authority, that Mr. Douce had the sixteenth edition of 1779.
