I wrote to you from Rokeby. I expressed my feelings respecting the gunpowder. I have been in extreme harass and anxiety from the idea of the use of my name, without the proper explanation, and I certainly expected that no use would have been made of it without my sanction. I never saw the label for the canister till it came to me upon one of them, and I immediately expressed that I was not satisfied with it. I told Mr. Burton expressly, that in all cases in which my name was used it must be in my own way. He is now at the head of your firm; but it is to _you_, and not to _him_, that I have given, and shall give my assistance. Every feeling of friendship and affection prompts my wishes to be useful to you; I have not the same relations to Mr. Burton. I am very sorry to give you any trouble on this business, but I am sure you cannot wish me to remain in a state of anxiety; and all the friends with whom I have consulted think it absolutely necessary for my reputation, that, when my name is used, a clear statement should be given of the true nature of the connexion. I think it will be more useful to you, and increase your influence and power in the partnership, if my assistance is stated as given to you, and to you only--in this way: "RAMHURST GUNPOWDER, manufactured by Messrs. Burton, Children, and Co. after an improved process, founded upon experiments and investigations made by Sir H. Davy, and communicated by him to Mr. J. G. Children, under whose immediate superintendence the gunpowder is made." I have fully made up my mind on this matter: and if you approve of the above form, I will state it to be the only one to which I will consent. If the gunpowder is called Sir H. Davy's powder, it must be stated in all cases where my name is used, that it is so called in honour of my discoveries in chemistry, and because I have given my gratuitous assistance in making the experiments and investigations on which the process is founded. I have resolved to make no profit of any thing connected with science. I devote my life to the public in future, and I must have it clearly understood, that I have no views of profit in any thing I do. I am, my dear Children, Very affectionately yours, H. DAVY. In subsequent letters, which it is not necessary to publish, Davy dwells upon the necessity of his engagements as a partner being legally cancelled, as he cannot endure the idea of his philosophical repose and usefulness being disturbed by the cares of business, or the trouble of litigation.
