There are two kinds, _viz._ The Primitive and the Degenerate; the Primitive Cancer is that which comes of it self, and appears at first about the bigness of a Pea or Bean, which nevertheless doth not cease to cause an inward Pain, continual, and pricking by intervals; during this time it is call'd an Occult Cancer; but when grown bigger, and open'd, it bears the Name of an Ulcerated Cancer; which is so much the less capable of being cur'd or asswag'd, as it makes it self more conspicuous by its dreadful Symptoms, or concomitant Circumstances. The Degenerate Cancer is that which succeeds an obstinate and ill-dress'd Tumour or Impostume, and which becomes an Ulcerated Cancer, without assuming the Nature of a blind or occult one. _What Remedies are requisite to be apply'd to a blind Cancer?_ {127} In regard that it cannot be known in this Condition without difficulty, it is often neglected; nevertheless it is a Matter of great Moment to prevent its Consequences, more especially by a good Diet, and by general Remedies, which may gently rectifie the intemperature of the Bowels: Afterwards Baths may be prescrib'd, together with the use of Whey Asses-Milk, and Specificks in general, as Powders of Crab's Eyes, Vipers, Adders, and others. As for Topical Remedies, none are to be administer'd, except it be judg'd convenient to apply to the Tumour a Piece of Lead rubb'd with Quick-silver; all others serving only to make the Skin tender, and apt to break. The Patient may also take for his Drink Water of _Scorzonera_ and Hart's-Horn, with the Flowers of Bugloss or Borage, and Liquorice: Or else Quick-silver-Water alone, boiling an Ounce of it in a Quart of Water every time, the Quick-silver always remaining at the bottom of the Vessel. _What are the Remedies for an ulcerated Cancer?_ Besides the general ones, that are the same with those of the blind Cancer, there are also Topical, which may take place here. The Powders of Toads, Moles, Frogs, and Crabs calcin'd, cleanse the Ulcers perfectly well. A Decoction of Vipers and Crabs may serve to bath 'em, and some of it may be taken inwardly. Detersives made of Lime-Water, or Whey clarify'd, and boil'd with Chervil are very good; and (if you please) you may add Camphire or _Saccharum Saturni_. {128} If the Pains grow violent, recourse is to be had to _Laudanum_, one or two Grains whereof may be given in a little Conserve of Roses. When the Cancer is situated in the Glandules or Flesh, the Extirpation of it may also be undertaken with good Success. As for the manner of handling Degenerate Cancers, respect must be always had to the kind of Tumour, from whence it deriv'd its Original. * * * * * CHAP. IV. _Of Bastard or _Encysted_ Tumours._ _What is an _Encysted_ or Bastard Tumour or Impostume?_ It is that which is made of a Setling of mixt and corrupt Humours, the Matter whereof is contain'd in certain proper _Cystes_ or Membranous Bags.
