When Mr. Talbot's patent for the @United @States expires and our native scientists have the opportunity to proceed with improvements, it is fairly certain that the calotype, in their hands, will supercede the Daguerreotype.
Let them, therefore, study the principles of the art, then experiment, practice, and perfect themselves in all its details so that they will be prepared when that day arrives.
It is to Professor @Samuel F. B. @Morse, the distinguished inventor of the Magnetic Telegraph, of New York, that we are indebted for the application of photography to portrait taking. He was in @Paris, for the purpose of presenting to the scientific world his @Electro-@Magnetic Telegraph, at the time (1838) M. Daguerre announced his splendid discovery; its astounding results, as well as its bearing on the art of design claimed his attention. In a letter on the subject, the Professor details the following interesting facts:
"The process was a secret, and negotiations were then in progress, for the disclosure of it to the public between the French government and the distinguished discoverer. M. Daguerre had shown his results to the king, and to a few only of the distinguished savants, and by the advice of M. @Arago, had determined to wait the action of the French Chambers, before showing them to any other persons. I was exceedingly desirous of seeing them, but knew not how to approach M. Daguerre who was a stranger to me. On mentioning my desire to @Robert @Walsh, @Esq., our worthy @Consul, he said to me, 'State that you are an American, the inventor of the Telegraph, request to see them, and invite him in turn to see the Telegraph, and I know enough of the urbanity and liberal feelings of the French, to insure you an invitation.' I was successful in my application, and with a young friend, since deceased, the promising son of @Edward @Delevan, Esq., I passed a most delightful hour with M. Daguerre, and his enchanting sun-pictures.
