Take of the white and inward Bark of the Witch-Hasel half a Handful, cut it short and stamp it, then take of the Roots of Marsh Mallows, Holy-hock Roots two or three Roots, clean them and throw away the Pith, stamp all together, then take of Fenugreek and Linseed of each two Ounces powdered, put all in an Earthen-pot, then take a Pint of white Wine or Water, heat it scalding hot, put it to the Things aforesaid, cover it close, stirring it every Day for nine Days, then strain out the Musilage Liquor with which you make the following Plaister. Take a Pint of Salad Oyl, Cerus finely powdered 8 Ounces, boil them together, constantly stirring them, a sufficient time, which you may know by its coming clear off a Pewter Dish when dropt on, let it cool a little and put in your Musilage, which stir till it be as white as you would have it, and until almost all the Musilage be boiled away, then remove it from the Fire and put to it four Ounces of _yellow Wax_, probably _Galbanum_ may be better, which when dissolved and the Plaister cold, work up for use. This Plaister is sometimes used with equal Parts of _Galbanum_. THE CASE OF Dr _JAMES KEIL_, Represented by _JOHN RUSHWORTH_. I Should not have been induced to make these Papers publick, barely on account of the rash Censures, that are frequently cast upon the Practice of _Surgery_, not attended with Success; tho’ that Consideration alone, in the Case of a Person of such Value and Eminency in _Physick_, as Dr KEIL is known to have been, may be thought sufficient to have moved me to it: But being certainly informed, That several _Physicians_ and _Surgeons_ have before, and since his Death, given themselves the Liberty to reflect, not only upon me for Using, but also upon the Deceased for submitting to the Methods that were taken with him; I think I shall not discharge my Duty, either to my Friend, or to my Self, or indeed to the Profession, if I do not, as far as I am able, endeavour to set what was done in a True Light. In order thereunto, it may be requisite to look back to the Time He first mentioned any Disorder in his Mouth to me, which was in _August_ 1716. He then told me, He had preceived a Fulness in his Mouth for very many Years; but in the last Three or Four Years it was much encreased, and by the Bulk began to be troublesome to him, tho’ not in the least painful: Upon examining it, I found the Tumour not only large, but also to fluctuate, and therefore told him, until I was satisfied what was contained in it, I could not come to a Resolution, as to the manner of treating it; but, if he pleased, I would make an Incision into it, and then would tell him what I thought was fit to be done; He was very well satisfied, and resolved I should proceed accordingly.
