Cooke, North-Semitic Inscriptions (Oxford, 1903) is the most useful.
Under the leadership of Dr Henry Cooke, a minister of rare ability and eloquence, the evangelical party triumphed in the church courts, and the Unitarians seceded and became a separate denomination.
In 1836 Cooke, to whom the idea appears to have been suggested by Schilling's method, invented a telegraph in which an alphabet was worked out by the single and combined movement of three needles.
Similar instruments to the single and double needle apparatus of Cooke and Wheatstone were about the same time invented by the Rev. H.
Another series of instruments, introduced by Cooke and Wheatstone in 1840, and generally known as " Wheatstone's step-by-step letter-showing " or " ABC instruments," were worked out with great ingenuity of detail by Wheatstone in Great Britain and by Breguet and others in France.
