What Means are to be us'd in order to cure a Caries proceeding from an external Cause?
The Powder of Flower-de-luce may be us'd, and it is sufficient for that purpose, when the Caries is superficial; but it is necessary to take Oleum Guyaci, and to soak Bolsters therein, to be laid upon the Ulcer when it is deep; or else Aqua-Vitæ or Brandy, in which have been infus'd the Roots of Flower-de-luce, Cinnamon, and Cloves. Lastly, the actual Cautery, which is Fire, must be apply'd thereto.
What is to be done when the Caries proceeds from an internal Cause?
The Flesh must be open'd to give Passage to the Sanies that runs out of the ulcerated Bone, to the end that Exfoliation may be procur'd; and if the Ulcer hath not as yet laid open the Bone on the outside, the Trepan ought to be apply'd; but the Ulcer or Caries must be afterward handled, as we have even now declar'd.
What is Exostosis?
It is the Swelling of a Bone made by the settling of a corrupt Humour in its proper Substance.
What is Nodus?
It is a kind of gummy and wavering Tumour, which is form'd by the settling of a gross Humour between the Bone and the Periosteum.
Are Exostoses and Nodus's suppurable Tumours?
Yes, because they sometimes produce Ulcers and Gangrenes in the Bone, which are call'd
