A Handbook of the Dragonflies of North America (Classic Reprint)

Excerpt from A Handbook of the Dragonflies of North AmericaOwing to the insistence of other duties the completion of this book has been long delayed. Many of the pupils of the senior author have contributed materials for it. It is no longer possible to name them all, but the help of all is gratefully acknowledged. In the final putting together of these materials there are those who have aided so well and so generously as to deserve special mention. Mrs. H. E. Seemann assisted in the preparation of materials and drawings. Miss Elsie Broughton helped with the completion of both drawings and manuscript; and most of the drawings of genitalia were made by Mr. 0. Francis Byers. Whole sections of the text have been written by the two last named. Dr. P. P. Calvert has very kindly read the galley proofs, and has helped with useful alterations and amend ments. He has enabled us to eliminate some errors, but for such as may remain he is in no way responsible.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
