THE seventiptrfi birthday of Prof. Henry Fairfield Osborn, president of the American Museum of Natural History, was celebrated by the presentation to him of a Queen Anne cup made by Thomas Folkingham in 1711, and an illuminated book containing an address of congratulation, with the signatures of his colleagues and friends all over the world. These signatures. were made on individual slips of vellum and included nearly a thousand names. The design and decorations of the book were executed by Mr. William E. Belanske. Owing to Prof. Osborn's absence from the city on Aug. 8—the date of his birthday—the Committee in charge of the celebration waited upon him at Garrison on July 28 to make the presentation. They also invited Prof, and Mrs. Osborn to be the guests of honour at a reception to be given them on Sept. 29, on which occasion the balance of the birthday fund raised by his friends, amounting in all to nearly seven thousand dollars, will be presented to Prof. Osborn for his research work.
