My Dear Sir,
As you are now of course busy settling your accounts for the Christmas quarter, and the close of the year near at hand, I beg leave to notice a little item connected with my accounts, and because my official connexion with the Society is about to terminate.
On leaving Yucatan there was a small sum, the balance of accounts, left owing to Don Vicente Calero of Mérida, which some he was to pay himself out of the proceeds of the Books sent him by the Society, and which would appear in his first account which we have been long expecting. This little sum was left in his hands partly as an inducement for him to do our work, whilst on his part the leaving it so was a testament he of his disposition to serve us. It was left also because it was inconvenient at the time to draw. This money, I may say, is in my hands, held ready to be paid whenever Mr. Calero's account should arrive. But on now retiring from the Society, I wish you to charge it to my Private Account, and hold it over for the purpose mentioned, namely, to meet the item in Mr. Calero's account on its arrival.
The sum in question is 81 dollars 5 rials, which at the then great of exchange, of 4 shillings to the dollar, makes £16:6:6.
In sending you this my last account, I seize the opportunity of thanking you, and most sincerely, for all the correct and kind attention you have all along paid to my accounts both public and private.
With best and kindest wishes for yourself, and all our Associates in Earl Street, believe me,
My Dear Mr Hitchin,
Sincerely and Affectionately Yours
James Thomson.
