A NOTE OF ACKNOWLEDGMENT
Deeply grateful to all who by encouragement have lightened our task or by assistance have furthered it, the editors, not unmindful of the significant helpfulness of the Advisory Council and the substantial aid of the Consulting Editors, devote this page of the series to that large body of unselfish contributors without whose generous cooperation the following pages would have been impossible. The names of these contributors recorded hereafter will evoke from readers of the intervening volumes the unstinted praise which in profound gratitude the editors now accord in fullest measure.
