occurred. Although knowing perfectly what lay before him, the young man kept unflinchingly onward. Wrapped up in his loved science and toiling like a strong man in the service of the academy which had won his boy-heart, he kept happily and wholesomely busy to the very end. His labor in a loved cause no doubt Fig. 7.-Captain Wilfred P. Hall. prolonged his life, but at last, December 10, 1881, the long expected summons came. The monument of that young life consists of a series of papers, chiefly entomological, of no mean merit—and the academy. In 1872 Duncan Putnam found his first specimen of Galeodes. This belongs to the family Solpugidæ, a curious group related to the spiders and scorpions. From that date on his interest centered upon this little-known and curious group. To so good profit did he labor that even now in our latest general authoritative work on insects Prof. Comstock names Putnam as the chief authority. The results of his study were not fully ready for publication at the time of his death, but Prof. Herbert Osborne put them in shape for the printer. They comprise one brief paper—Notes on Solpugidæ, an important Bibliography, and data for a Monograph upon the American Galeodidæ. All of this material, beautifully illustrated by the author's own drawings, was published in the memorial volume of the Proceedings. Besides the material upon the Solpugidæ, Mr. Putnam's work includes a score of important papers which were printed in the Proceedings, Popular Science Monthly, United States Government reports, etc. The whole motive in J. Duncan Putnam's work was to do what ought to be done. As he himself once said, "If others are unwilling to do what ought to be done, I must." No one outside his family knew him better than Dr. Parry, who said of him: "Though over thirty years his senior in the broad field of Nature, we occupied the same level. Always respectful to my personal wishes or suggestions, never flinching from any imposed duty, always cheerful, hopeful, and zealous, he proved a companion worthy of the highest regard, which he never forfeited either by word or deed." By his activity in field work Mr. Putnam gathered a collection of twenty-five thousand specimens, representing more than eight
