no good Effect here, nor will they consume the remaining Part of the _Cancerous Mass_. We have elsewhere shewed, that this Substance upon boiling becomes hard and friable; and we will here take the Liberty to give our Opinion of the Use of Cauteries in this Case. The _Cancerous Substance_ we take to be nothing more than a Transformation of the small glandulous Bodies, which form the Breast, and a Lymphatick Juice, intimately incorporated therewith, into a hard, close, whitish, and (by common Medicines) indissolvable _Mass_. In some Cases, perhaps, it may receive some Addition from some Juices, which may distil from the contiguous Fibres. This being granted, what Benefit, can we reasonably imagine, will ensue on this painful Method? Will not the Fire, by causing the more Fluid Parts of the _Mass_ to evaporate, actually dry up, torrefy, and harden it; and so dispose it for displaying a Train of mischievous Effects, on the contiguous Parts? and all this without any very apparent Decrease of it too: Nay, the very reducing of it to such a Consistence, which very much resembles a Piece of burnt Horn, is sufficient to procure a perpetual Pain, seeing Medicines can hardly soften it, so as to reduce it to its first State. PROBLEM IV. _Whether_ Salivation _will Cure a_ Cancer. The extraordinary Success this Method has been attended with, in some Cases of the greatest Difficulty, has so far recommended it to the World, that it is at this Time become of so great Repute, that there are few Persons but what will willingly embrace it, if proposed to them, provided they have found former Methods prove ineffectual. We once knew a Person, who laboured under an ulcerated _Cancer_ in her Breast, advised to it, and who had certainly under-gone it, though contrary to the Opinion of some Persons concerned, if in three or four Days time she had not been reduced to such a weak Condition, that it put an End to the Controversy. That a _Salivation_ has cured the most malign and spreading Ulcers, and those that have been of several Years continuance, notwithstanding their Edges have been high, inverted and assumed the Consistence of a callous Body, we have found by several Instances; but that it should cure a _Cancerous Ulcer_, an _Ulcer_ which is chiefly seated in a transformed animal Substance, and which has no Correspondence with the contiguous Parts, is what we cannot believe. One of the principal Effects of _Mercury_, if prudently given, is, that it attenuates the Juices, clears the Canals, destroys the ill Quality of that Fluid that has a Hand in causing any Obstruction, and renders the Juices temperate and sweet. By effecting this, it is, that it cures so many different Diseases, which perhaps have not so great a Diversity in their Causes, but have different Appearances, which depend upon the Variety of Parts, where the Cause operates. From hence any One may judge, that a Person who discovers a certain
