But then in _April_ 1718. He shewed me a small _Ulcer_, near that Part of the Mouth that was before affected, and told me, He perceived it began upon eating some hot Meat, that stuck to it: At first this healed without much Trouble, but soon excoriated again; and then I could not again perfectly skin it: For as soon as it was almost healed, it would begin to excoriate a-fresh at the Edges, which is what is usual in _Phagedænical Ulcers_. And tho’ I could digest it, and keep it easy, yet it got ground of me, and spread towards the Teeth; and, near the Root of One of the _Molares_, laid the Bone bare, which appeared to me at the first not to be injured, but being long exposed became foul. It not exfoliating in due Time, with the Tincture that is commonly used, I proposed the touching of it with a small _Cautery_, I being able very easily to come at it without making use of a _Cannula_; which, by confining the Heat, very much injures the neighbouring Parts: The good Effect of which Practice, of not making use of a _Cannula_, where you can conveniently omit it, I had good Experience of in Doctor _KEIL_’s former Case: For tho’ he had several _Cannulas_ made in _London_, by the best Hand, yet after Twice using of them, I told the Doctor, That if a Patient could be trusted, it would be much more easy to him, and the Surgeon would see much better to use the _Cautery_, than when obstructed by a _Cannula_. The Doctor was pleased with the Thought, and pressed me, at the next making use of the _Cautery_, to do it without the _Cannula_: The Advantage he had by it was, that it bore four Burnings, and said, It gave him not the Pain, or Trouble he had from but One before, and that the Parts were much less Disordered by it afterwards. But to return: It will not I suppose be doubted, but that proper internal Means were all along made use of: But the _Ulcer_ still appearing to me more threatening, his Friends pressed him, and I more than any, that he would go again to Town, and have the best Advice it could afford; and I resolved to accompany Him, in the Beginning of _August_ 1718. And I cannot forbear saying I was surprized, when, upon a Consultation, my Brothers, _Palmer_ and _Brown_, made light of it; and, without so much as hearing what I had to say, concluded, That it was chiefly owing to the Bones being foul; and that by drawing a Tooth or Two which they said were affected, and by Purging with _Mercurius dulcis_, all would be well; and so they took their Leave. Says the Doctor to me, “What say you to this?” I answered him, That I feared they would find themselves again mistaken as to the _Surgery_ Part; and that as to the _Mercury_, though a good Medicine, He knew he had taken it already several Times, without any considerable Advantage. The Doctor smiled and said, “But since I came so far for Advice, I will not only give them a Tooth, but also try again what Effect _Mercury_ may have.”
