 Professor Wheatstone ? ', 8vo. (pp. 74), sewn (scarce), 6s Gd 1855 



' He was not the ' inventor' of the electric telegraph. Indeed no one can lay claim to that title. . . . But to Wheat- 

 stone, with his coadjutor SIR WILLIAM FOTHERGILL COOKE, is due the merit of having been the first to render it available 

 for the public transmission of messages.' Prof. Silvanus Thompson, F.R.S. 



See Nos. 7010-1 ante for Sir W. F. Cooke's pamphlet provoking the above reply.

 and Springs, with Account of the Universal Deluge : and of the Effects that it had upon the 

 Earth, first edition 2 vols. 8vo. in 1, sound copies in old calf, 1. 5s 1696-5 



'The MS. was shown to Newton and Wren. It was praised by Locke . . . Whiston's speculation was meant to supersede 

 the previous theory of Thomas Burnet. He confirmed the narrative in Genesis on Newtonian grounds, explaining the 

 Deluge by collision with a comet". Sir Leslie Stephen. 



' Whiston was one of the first who ventured to propose that the text of Genesis should be interpreted differently from 

 its ordinary acceptati m, so that th doctrine of the earth having existed long previous to the creation might no longer be 

 regarded as unorthodox . . . Locke pronounced a panegyric on his theory, commending it for having explained so many 

 wonderful and before inexplicable things.' Sir Charles Lyell. The work was attacked by JOHN KEILL (v. No. 10021 ante). 



It is a touching fact in Eighteenth Century Arianism that 'whatever doubts it may have had as to the cardinal fact of 

 Christianity, it was as unswervingly faithful to the Deluge as his wife was to Mr. Micawber.

Whiston was one of the first to popularise the Newtonian theories, and, according to Professor de Morgan, one of the 

 first to give lectures with experiments in London. He is thought to have suggested Dr. Primrose.
