Whaling Logbook, kept by ship's surgeon Dalton while aboard the whaling ship HARRIET on a voyage to and around the Pacific Ocean via Cape Horn. Includes illustrations of whales throughout, a list of sperm whales sighted or caught and how much oil stowed in the vessel (starting at the back of the volume), and an autobiographical note near the back of the volume, written in 1866. Inserts of Chinese blotting paper were found between the pages, and have been put in a separate folder.

Administrative / biographical background
Ship's surgeon Dalton studied at St Thomas's Hospital and Grainger's Anatomical School and officially qualified in 1830. He lived in London, and later Cheltenham, and retired in 1869. During his retirement he joined a clipper ship at Gravesend on voyages to Australia and the Azores. There is a note on the first page of this volume by Arthur Dalton Bond, the author's grandson. He helped to found the Royal Medical Benevolent College, Epsom, with John Propert and friends.
