Three of the papers in this volume have been privately printed. I have
added, however, some new matter to the sketches of Ainsworth and James;
and it has been suggested to me that those sketches should be published,
although I have some misgivings about them. The other paper I am
reprinting merely to please myself. Two men have confided to me that
they have read it, and possibly two more may be persuaded to do the same
thing.
November, 1909.
