Shortly after, these details reached the United States, by Professor S.F.B.Morse, of New York, who was, at the time of the discovery, residing in Paris.

By this announcement, the whole scientific corps was set in operation, many repeating the experiments, following carefully the directions pointed out by Daguerre, as being necessary to success.

Among the number in the United States, was Alexander S.Wolcott (since deceased) and myself; both of this city.
On the morning of the 6th day of October, 1839, I took to A.Wolcott's residence, a full description of Daguerre's discovery, he being at the time engaged in the department of Mechanical Dentistry, on some work requiring his immediate attention, the work being promised at 2 P.M.
that day; having, therefore, no opportunity to read the description for himself (a thing he was accustomed to do at all times, when investigating any subject).

I read to him the paper, and proposed to him that if he would plan a camera (a matter he was fully acquainted with, both theoretically and practically), I would obtain the materials as specified by Daguerre.

This being agreed to, I departed for the purpose, and on my return to his shop, he handed me the sketch of a camera box, without at all explaining in what manner the lens was to be mounted.
