Autograph Note in the third person, with signature ('Harry G Seeley | Assistant to Professor Sedgwick'), to Kerrison Harvey, containing a humourous flight of fancy regarding dinosaurs.

12mo, 3 pp. Bifolium. Fair, on lightly-aged paper with thin horizontal strip of discoloration caused by glue from mount on blank reverse of second leaf. The twenty-one line note, on the first two pages, explains that Seeley would have sent 'the signature which he was so kindly asked for a month ago' sooner, 'but many things clamoured to be done; the Pterodactyls had to [be] fed, and coaxed to associate with their new-found friends the Birds; the Ichthyosaurs had to be given a patent of greater nobility; and finally he had to make up the Cambridge Coprolite bed, and put fresh sheets upon it!' The signature, with the date beneath, is on a separate page, beneath the letterhead. Lighthearted as the note may be, it points towards Seeley's genuine achievements in the field of paleontology. It was he who determined that dinosaurs fell into two great groups, the Saurischians and the Ornithischians, based on the nature of their pelvic bones and joints.
