tailed criticism of an earlier version of this work has been in-
valuable.

The staffs of the New York Public Library, the Library of
Congress, and the libraries of New York and Harvard Universi-
ties have been most helpful. I recall with special pleasure
the time spent at the Sterling Memorial Library of Yale Uni-
versity, whose librarians made the stacks and Rare Book
Room my home for six weeks during the spring of 1959.

I offer my thanks to the graduate faculty of New York Uni-
versity's Department of English for its interest in this project
and encouragement of it, and to the Graduate School of Arts
and Science of that university for the award of a Penfield Fel-
lowship which made this work possible.

The greatest debt of all, one which can never be repaid, I
mention last. Three teachers and one friend of long standing
have done more to stimulate and direct the organization of my
thought than the meagre references to published evidence of
their intellectual activity can possibly indicate. Professors
Kathrine Koller, Lewis White Beck, and Robert B. Hinman,
of the University of Rochester, have proved themselves--in
seminar and conversation, by precept and example--to be the
three best teachers I have had the pleasure to study with.
Robert Rosen, whom I have seen less often than I would like
since we first met eleven years ago, is now with the Committee
on Mathematical Biology at the University of Chicago. Not even
his inherent modesty can obscure his broad critical intelli-
gence.

If the reader of this book finds that it has helped him to bet-
ter understand the structure of Addison's critical thought, his
thanks should go to all of these masters.
