Observations on Several Parts of Africa
Arthur Jermyn's great-great-great-grandfather, Sir Wade Jermyn, was one of the earliest explorers of the Congo region, and had written eruditely of its tribes, animals, and suppoed antiquities. Indeed, old Sir Wade had possessed an intellectual zeal amounting almost to a mania; his bizarre conjectures on a prehistoric white Congolese civilisation earning him more didicule when his book, Observations on the Several Parts of Africa, was published. In 1765 this fearless explorer had been placed in a madhouse at Huntingdon.
