Feb [21,?] 1894 Eadwaard Muybridge, Esq., University of Pennsylvania, Philadelphia, Pa. Dear Sir:-- I have received your little book on Zoopraxography, for which please accept my thanks. I have constructed a little instrument which I call a Kinetograph, with a nickel-in-slot attachment. Some twenty-five of these have been made, but I am very doubtful if there is any commercial feature in it. I fear that they will not earn their cost. These zeotropic devices are of too sentimental a character for the public to invest in. Yours very truly, Thomas A. Edison M.
