Sir J. Herschel
Athm Club <1>
I am much obliged by your note received this morning.
I have therefore thought it right to send you a copy of it, and at the same time to ask you for a short affidavit in reply to that part only of Mr H’s affidavit which names yourself (not noticing any other part of it). I have followed partly the wording of the note I received from you this morning. The rest I have drawn up in words that I thought you would likely to adopt, but if not, pray alter them to others. I find that I need not trouble you to call at Lincolns Inn, for as soon as the words of the affidavit are settled, and you appoint a time, I can call on you with a solicitor either in Harley St of an evening, or at the Mint, at an earlier period of the day. I have just now taken down the Transns of the Royal Society for 1840, and carefully reperused your paper <4> and can find no other mention of gallic acid than that at page 8, which therefore I conclude to be the passage referred to my Mr Hunt. I think the Vice Chancellor will hear the cause on Friday, therefore tomorrow or Thursday are the days on which I could call on you with a solicitor empowered to take an affidavit. (This is a new arrangement, very convenient for persons engaged in legal proceedings).
Yours very truly
H. F. Talbot
