It is unnecessary to review the testimony for the purpose of showing this.

His application for a patent, in April, 1838, was preceded by a series of experiments, results, illustrations and proofs of final success, which leave no doubt whatever but that his great invention was consummated before the early spring of 1837.

There is no one person, whose invention has been spoken of by any witness, or referred to in any book as involving the principle of Mr.Morse's discovery, but must yield precedence of date to this.

Neither Steinheil, nor Cooke and Wheatstone, nor Davy, nor Dyar, nor Henry, had at this time made a recording telegraph of any sort.

The devices then known were merely _semaphores_, that spoke to the eye for a moment--bearing about the same relation to the great discovery before us as the Abbe Sicard's invention of a visual alphabet for the purposes of conversation bore to the art of printing with movable types.
