The two letters that he substituted were addressed one to Mr. King and the other to Lord Howick.
The copy of the King letter, now in the possession of the writer, is dated but not signed. In it he still gave vent to some of the bitterness and threats contained in the letter to Lord Grenville, but in gentler tone. As the censure is not now addressed to Lord Grenville but to his secretary the irritating character is much softened.
Ibbotsons Hotel June the 20th 1806
Mr. King
Sir
Your Silence on my several letters Is a want of politeness and an Injustice which I feel in the most sensible manner I have offered His Majestys Ministers the Most rational and honorable terms, by proposing to submit my whole plans to men of science and arbitrators if Ministers have not time or doubt their own [power] ability to Judge of the powers and consequences of new inventions how can they expect to arrive at truth or get correct Ideas but through the medium of Men of Sciences, of their own appointment, to refuse such a proposal and what is worse to treat it with contempt is injustice to the nation and to me and is [the] sufficient to sink any man or men in the opinion of the [nation] public. I hope I Shall not be driven to the necessity of appealing to the public opinion on this point but that I Shall have prompt and reasonable attention immediately paid to my claims I hope sir for your immediate answer
The letter to Lord Howick is a model of self-restraint as compared with the violent outburst of the withheld epistle to Lord Grenville:
