"Morse's machine was complete in all its parts and operated perfectly through a circuit of some forty feet, but there was not sufficient force to send messages to a distance. At this time I was a lecturer on chemistry, and from necessity was acquainted with all kinds of galvanic batteries, and knew that a battery of one or a few cups generates a large quantity of electricity capable of producing heat, etc., but not of projecting electricity to a great distance, and that, to accomplish this, a battery of many cups is necessary. It was, therefore, evident to me that the one large cup-battery of Morse should be made into ten or fifteen smaller ones to make it a battery of intensity so as to project the electric fluid.... Accordingly I substituted the battery of many cups for the battery of one cup. The remaining defect in the Morse machine, as first seen by me, was that the coil of wire around the poles of the electro-magnet consisted of but a few turns only, while, to give the greatest projectile power, the number of turns should be increased from tens to hundreds, as shown by Professor Henry in his paper published in the 'American Journal of Science,' 1831.... After substituting the battery of twenty cups for that of a single cup, we added some hundred or more turns to the coil of wire around the poles of the magnet and sent a message through two hundred feet of conductors, then through one thousand feet, and then through ten miles of wire arranged on reels in my own lecture-room in the New York University in the presence of friends." This was a most important step in hastening the reduction of the invention to a practical, workable basis and I wish here to bear testimony to the great services of Professor Henry in making this possible. His valuable discoveries were freely given to the world with no attempt on his part to patent them, which is, perhaps, to be regretted, but much more is it to be deplored that, in, the litigation which ensued a few years later, Morse and Henry were drawn into a controversy, fostered and fomented by others for their own pecuniary benefit, which involved the honor and veracity of both of these distinguished men. Both were men of the greatest sensitiveness, proud and jealous of their own integrity, and the breach once made was never healed. Of the rights and wrongs of this controversy I may have occasion later on to treat more in detail, although I should much prefer to dismiss it with the acknowledgment that there was much to deplore in what was said and written by Morse, although he sincerely believed himself to be in the right, and much to regret in some of the statements and actions of Henry.
