I am acquainted with no fact which would lead me to suppose that the project of the electro-magnetic telegraph is unpractical; on the contrary, I believe that science is now ripe for the application, and that there are no difficulties in the way but such as ingenuity and enterprise may obviate.  But what form of the apparatus, or what application of the power will prove best, can, I believe, be only determined by careful experiment.  I can say, however, that, so far as I am acquainted with the minutiae of your plan, I see no practical difficulty in the way of its application for comparatively short distances; but, if the length of the wire between the stations is great, I think that some other modification will be found necessary in order to develop a sufficient power at the farther end of the line.

I shall, however, be happy to converse freely with you on these points when we meet.  In the meantime I remain, with much respect

Yours, etc.,
JOSEPH HENRY.

I consider this letter alone a sufficient answer to those who claim that Henry was the real inventor of the telegraph.  He makes no such claim himself.

In spite of the cares of various kinds which overwhelmed him during the whole of his eventful life, Morse always found time to stretch out a helping hand to others, or to do a courteous act.  So now we find him writing to Daguerre on May 20, 1839:—­

My dear sir,—­I have the honor to enclose you the note of the Secretary of our Academy informing you of your election, at our last annual meeting, into the board of Honorary Members of our National Academy of Design.  When I proposed your name it was received with enthusiasm, and the vote was unanimous.  I hope, my dear sir, you will receive this as a testimonial, not merely of my personal esteem and deep sympathy in your late losses, but also as a proof that your genius is, in some degree, estimated on this side of the water.

Notwithstanding the efforts made in England to give to another the credit which is your due, I think I may with confidence assure you that throughout the United States your name alone will be associated with the brilliant discovery which justly bears your name.  The letter I wrote from Paris, the day after your sad loss, has been published throughout this whole country in hundreds of journals, and has excited great interest.  Should any attempts be made here to give to any other than yourself the honor of this discovery, my pen is ever ready for your defense.

I hope, before this reaches you, that the French Government, long and deservedly celebrated for its generosity to men of genius, will have amply supplied all your losses by a liberal sum.  If, when the proper remuneration shall be secured to you in France, you should think it may be for your advantage to make an arrangement with the government to hold back the secret for six months or a year, and would consent to an exhibition of your results in this country for a short time, the exhibition might be managed, I think, to your pecuniary advantage.  If you should think favorably of the plan, I offer you my services gratuitously.
