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

' 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 diflferently from 

 its ordinary acceptation, so that the 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 ft for having explained so many 

 wonderful and before inexplicable things.'— .S'lrCTiar^ 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.
