discourse with each other, without moving the lips or tongue. This
alphabet was originally invented in Scotland, and at the present
day is much in use there, not only amongst dumb people, but many
others, who employ it as a silent means of communication. Nothing
is more usual than to see passengers in a common conveyance in
Scotland discoursing with their fingers. Duncan at an early period
gave indications of possessing the second sight. After various
adventures he came to London, where for many years he practised as

particular people by fits and starts, and which is quite

hands of Defoe, who wrought them up in his own peculiar manner, and
gave them to the world under the title of the Life of Mr Duncan
Campbell, the Deaf and Dumb Gentleman: with an appendix containing
many anecdotes of the second sight from Martin's tour.

Christianity was introduced into Iceland, he was amongst the first
