Senses, to contradict his Master, who constantly affirms all the Veins in Man’s Body to have their Original from the Heart; because, said he, it is much more easy for our Senses to be sometimes deceived, than the Great and Sovereign_ Aristotle. I here seriously confess, I have as much Veneration for Antiquity as any Person whatsoever; but it would be ridiculous, if, as One says, we should so far forego our own Judgments as always to follow the Foot-steps of Others, and to be certain of nothing our selves: For this would be to see with others Eyes, to hear with others Ears, and to understand with other Men’s Intellects; so that whenever we make Quotations from the Ancients to strengthen our Opinions, we ought to do it judiciously, and fully consider, whether their Notions of Things are consonant to the Experience of these Times. To prove to you, _Sir_, that I have not proceeded to apply my self to the Cure of so formidable a Disease, without a Precedent, I shall instance to you that _Fuschius_, a learned _Italian Surgeon_, had such a wonderful Reputation for it formerly, that some Authors say he was distinguished by a particular Title, which discovered his Success. His Method I have made use of, and tho’ by passing thro’ several Hands (the Author being mentioned by few) it has been stampt with wonderful Encomiums, I have not hitherto found it deserves it, notwithstanding I did not omit the most minute Circumstance in preparing the Medicine, or prosecuting the Directions; but in its proper Place, I shall take particular Notice of this, and several other Remedies, that have been recommended by some Authors, as substantial and extremely useful; for if in One or Two Instances they have been crowned with Success, by Degrees they are handed down as infallible in all Diseases of the like Form. To the former Account I may add, that Monsieur _Alliot_, _Physician_ to the Duke of _Lorrain_, has applied himself to the Cure of this Disease very successfully, as a _Schedule_ he published at _Paris_ some Years ago informs us; we are likewise assured by Mr _Boyle_ that Dr _Haberfield_, one of the Principal _Physicians_ of _Bohemia_, has had extraordinary Success in the Cure of _Cancers_; and the Sieur _Gendron_, Doctor of _Physick_ in the University of _Montpelier_, has done extreamly well on that Head; the latter of these Gentlemen I cannot mention, without making an Apology for not Publishing our Annotations on his Enquiries relating to _Cancers_ which was promised at the latter End of our Chirurgical Remarks, Printed above a Year ago; but I assure you, _Sir_, I was more inclined for some Reasons to offer what is therein contained, with several Observations made with the greatest Exactness, and to which, perhaps I may have an Opportunity of making several Additions, in a particular Treatise, so that the whole may conspire to finish a compleat Account of this Disease. I had at first a Design of enlarging considerably on this
