The Cancer at first is not so big as a Pea, being a small, hard, blackish Swelling, sometimes livid, and very troublesome by reason of its Prickings; but when it is encreas'd, the Tumour appears hard, Lead-colour'd, and livid, causing in the beginning a Pain that may be pretty well endur'd, but in the increase it grows intolerable, and the Stink is extremely noisome. When it is ready to Ulcerate, the Heat is vehement, with a pricking Pulsation; and the Veins round about are turgid, being {224} fill'd with black Blood, and extended as it were the Feet of a Crab or Crey-Fish, till Death happen. When this Tumour is not ulcerated, it is call'd an _Occult Cancer_; and an _Apparent_ one when it breaks forth into an open Ulcer. To palliate an Occult Cancer, and prevent its Ulceration, a Cataplasm or Pultis of Hemlock very fresh may be apply'd to the Part. All the kinds of Succory, the Decoction of _Solanum_ or Night-shade; the Juices of these Plants, as also those of Scabious, _Geranium_ or Stork-Bill, _Herniaria_ or Rupture-Wort, Plantain, _&c._ are very good in the beginning. River-Crabs pounded in a Leaden-Mortar, and their Juice beaten in a like Mortar, are an excellent Remedy; as also are Humane Excrements or Urine destill'd, and laid upon the Occult Cancer: Or else, Take an Ounce of calcin'd Lead, two Ounces of Oil of Roses, and six Drams of Saffron; let the whole Composition be beaten in a Mortar with a Leaden Pestle, and apply'd. The Amalgama of _Mercury_ with _Saturn_ is likewise a very efficacious Remedy. In the mean while the Patient may be purg'd with black Hellebore and _Mercurius Dulcis_, taking also inwardly from one Scruple to half a Dram of the Powder of Adders, given to drink, with half the quantity of Crab's-Eyes: But very great care must be taken to avoid the Application of Maturatives or Emollients, which wou'd certainly bring the Tumour to Ulceration. {225} When the Cancer is already ulcerated, the Spirit of Chimney-Soot may be us'd with good Success; and the Oil of Sea-Crabs pour'd scalding hot into the Ulcer, is an excellent Remedy. But if it be judg'd expedient entirely to extirpate the Cancer, it may be done thus:
