Colloquium publications.

PREFACE

The American Mathematical Society held its Eighth Colloquium in connection with the Twenty-Third Summer Meeting
at Harvard University during the week of September 3-9, 1916.
At this Colloquium the following lectures were delivered:
I. Functionals and their Applications. Selected Topics, including Integral Equations. By Professor Griffith C. Evans of
the Rice Institute.
II. Analysis Situs. By Professor Oswald Veblen of Princeton
University.
The present volume, which is issued as Part I, contains Professor (now Captain) Evans's lectures. Professor (now Captain)
Veblen has been prevented by national service from preparing
his manuscript for publication. The Committee hopes that, in
the not too distant future, his lectures may appear as Part II of
a single volume. It seems best, however, to issue Professor
Evans's lectures promptly, even though a certain discontinuity
may thereby result.
