A.L.S., Humphry Davy, three pages, 4to, Montpelier, 17th (?) (January) 1814, to Monsieur Le Baron Delessert in Paris. Davy states that he has 'not yet profited by your letter of credit' and adds that he proposes to stay at Montpelier for a further ten days and would like the letter of credit sent there, explaining 'I am just going to make a journey to the extinct volcanoes in this neighbourhood & on my return I will send you bills of exchange for as much money as I shall want whilst I am in the south of France.' In a postscript Davy remarks 'If you can have the goodness to transmit the enclosed letter (no longer present) to London it will serve as a letter of notice to Messrs Drummond & Messrs Morland & Co in case the other letters should have miscarried'.
