This paper I read to the Arbitrators on the morning of this date and it is deposited with the Government. In the letter to Lord Grenville referred to above and given at length below, Fulton, it will be seen, states that he had deposited twelve drawings with descriptions of facts in the hands of Mr. King, secretary to Lord Grenville. This is undoubtedly what he means by the statement in his notes of the paper read to the arbitrators having been “deposited with the government.” As the drawings were intricate and the paper very long, it is hardly probable that Fulton made three copies including the copy of the paper and tracings of the drawings that he brought home. As neither Mr. King nor the arbitrators had any need for the drawings and paper, it is quite likely that they were returned to Fulton, who left them with Consul Lyman as described in his letter to Barlow and which are consequently the foundation of this book. The letter to Lord Grenville to which Fulton refers is worthy of reproduction as it is a general summary of his case written immediately before his departure for America. It is his last appeal, and in it he uses every argument that occurs to him. Ibbotsons Hotel, September the 3d 1806 To the Right Honorable Lord Grenville My Lord As the subject of which this letter will treat is of the utmost importance in as much as it may render the power and independence of Great Britain doubtful and a wrong judgement of it may not only involve the country in complicated evils but attach eternal blame to his Majesty’s present ministers of whome your Lordship is one. I Shall hope for your calm perusal and deliberate contemplation of the following facts and observations on the means which science has developed for destroying military marines and in such case what would be the fate of England? There is one suit of thinking which gains easy access to an intelligent mind, and opens the way to a right Judgement on the progress of the arts and the possibility of effecting every thing which is within the limits of physics it is that all science is progressive every year exhibits new combinations and effects, Steam engines, Cotton Mills, Telegraphs, Baloons, and submarine navigation and attack have all appeared almost within our memory, and only Vulgar minds harbour the thought that a Physical possibility is impracticable because it has not already been done. It does not require much depth of thought to trace that science by the discovery of Gunpowder changed the whole art of war by land and sea and may by future combinations sweep military marines from the ocean My Lord I have discovered the means which may produce such an effect, and by ample experiments proved them true, that is I have proved them to a degree which should convince every reflecting and unprejudiced mind, Common minds which
