London Zoo is the world's oldest scientific zoo. Opening in 1828, it was originally intended to be used as a collection for the scientific study of animals. The animals of the Tower of London menagerie were transferred to the zoo's collection in 1831-32. It was opened to the public in 1847. It is managed by the Zoological Society of London (established in 1826), and is situated at the northern edge of Regent's Park. Charles John Cornish (1858-1906) was a well known popular English naturalist and author; he published this book in 1895.
