Responsibility for the following collection of essays and addresses (occasional papers) rests perhaps not more with their writer, who was not unwilling to see them presented in a single volume, than with those of his friends who were complimentary enough to urge their assemblage and publication in this shape. They partake of the character of studies in that borderland of anthropology, biology, philology and history which surrounds the immediate domain of medical and general science. This ever offers a standing invitation and an enduring fascination for those who will but raise their eyes from the fertile and arable soil in which they concentrate their most arduous labors. Too close confinement in this field may result in greater commercial yield, but the fragrance of the clover detracts not at all from the value of the hay, nor do borderland studies result otherwise than in enlargement of the boundaries of one's storm center of work.

No strictly technical nor professional papers have been reprinted herein, while several of those which appear do so for the first time.

Buffalo, December, 1912.
