developed were applied by Dr. Gale to render Morse's machine 

 effective at a distance." This statement seems to me to be as direct, 

 as clear, as truthful, and as comprehensive as one can desire. i he\ 

 are Henry's own words, and we all receive them as entirely satis- 

 factorv. '•The principles 1 had developed were applied by Dr. 

 Gale to render Morse's machine effective at a distance." Observe, 

 Henry does not claim to have had any part in rendering Morse's 

 machine effective when near the battery; no, because that was the 

 condition of the machine before Morse called in the assistance of 

 Dr. Gale in the winter of 1836-37; but Henry does claim this: 

 by his discoveries to have given Dr. Gale the principles which ]>r. 

 Gale applied to Morse's machine and rendered it effective at a dis- 

 tance; nor line- Henry claim Morse's ingenious marking machine — 

 a lever, one of whose ends is attracted by the electro-magnet against 

 an opposing spring, while the other end of the lever makes a mark 

 on a moving surface. Nor does Henry claim any of the other 

 ingenious mechanical combinations invented by Morse. Henrys 

 claim is the claim of a discoverer not of an inventor; for he says: 

 "The principles 1 had developed were applied by Dr. < rale to render 

 Morse's instrument effective al a distance. 



Henry does not claim that his own telegraphic machine (which 

 was undoubtedly an original invention) had been appropriated by 

 Mr. Morse; certainly not, because it is an entirely different inven- 

 tion. And here let me call your attention to an important fact, viz : 

 Neither Henry nor Morse could lay claim to having originated the 

 idea of causing a voltaic current to produce electro-magnetic actions 

 at a distance; yet the majority of persons, who have nof examined 

 into the history of telegraphy, think that this is the very point at 

 issue between Henry and Morse. 



Finally, I will take the liberty of remarking that had Henry 

 taken out a patent in which he claimed as his invention an electro- 

 magnet formed of two or more layers of insulated wire, Morse's patent 

 would not have been so valuable. Remember, 1 -peak not of the 

 merit of the invention, but of the merit of the patent; for the 

 invention, so far as Morse is concerned, would have remained the 

 same, because our essential part of a Morse telegraph is Henry's 

 intensity magnet, and certainly Morse never invented that.
