Mr. Vaughan communicated to me a very ingenious and judicious Letter (as it appear’d to me) written by you on the Subject of calculous Complaints and the Remedies that had been propos’d for them. You were so good as to say that if I would send you a state of my Case, you might perhaps be able to point out some Plan of Proceeding that would be serviceable. I omitted it then, thinking the Disease had left me; and hoping by the Use of Honey to prevent its Return. I was however mistaken, as you will see in the Case, but have not since had recourse to any Medicine. I now request your Opinion and Advice; and am, with great Esteem, Sir, Yours most obedient and most humble Servant
