It was while the late Mr.Broderip, the barrister, was acting as a London police magistrate, that he was attracted to the study of natural history, in which he occupied the greater part of his leisure.

He wrote the principal articles on the subject for the 'Penny Cyclopaedia,' besides several separate works of great merit, more particularly the 'Zoological Recreations,' and 'Leaves from the Notebook of a Naturalist.' It is recorded of him that, though he devoted so much of his time to the production of his works, as well as to the Zoological Society and their admirable establishment in Regent's Park, of which he was one of the founders, his studies never interfered with the real business of his life, nor is it known that a single question was ever raised upon his conduct or his decisions.
