[D8805AKS], Letter from Charles Edward Munroe to Thomas Alva Edison, 1888

Editor's Notes

"Apropos of the principal topic of the conversation at your house during the very pleasant evening I spent there let me call your attention to a note in the Popular Science Monthly Vol. 14, pg. 692, year 1879 entitled the Electric Light as a source of nitric acid. ### I have been recently getting some results on the iron plates this and more curious than any shown in N.Y. and which I believe may have a real scientific value. But I am so busy in application especially in shooting nitro glycerine acid gun cotton out of gunpowder [unclear] that I don't get much chance to carry on these plate experiments. The firing trials are however a great success. Friday I fired three pounds of perfectly dry gun cotton enclosed in a shell the whole weighing 3 1/2 pounds. This was fired from an 24-lb howitzer with a charge of 2lbs of poweder (the service charge). The shell was fired into a masonery encampment 50 yds distant. The force was sufficient to smash the shell when it struck but the gun cotton was not exploded. I think it won't be long before we are firing 300 or 400 lbs of this exposive out of our old fashioned 15-inch guns. When you recall that in my plate experiments I only used 10 yo. Unconfined gun cotton you can imagine what this 400 lbs may do when confined and moving at 1000-1500 feet per second. We should be so lucky off after all should sudden war arise." Yours truly, Charles E. Munroe "Admiral Luce seems to be setting on your suggestion about signalling some of the reporters [unclear] to be inquiring as to when the experiments due to begin."
