XCVIII. Soffle ObfivaSs 2fi4n tbe <gars, late.ly applied after 24mputattenr, wxth re- gard to zbe deterginirg szs SpFer. By Mr. WGliam Watfon, F. R. S.

754- 1 tic after amputations, and which has been brought from France, 1 do not beliesre to be the common agaric of the oali, as has been ima glned by tihe French furg¢ons. What is called the comm agaric is a paraival plant, found vowing upon the oak, and upa feveral oNer trees; andr is denominated by Cafpar l3?Wtlhin, hsgus in audicibvs naJvens uxguis eixi ftigurS; of whi¢h touchwood or fpunk, and the amado¢ ordinaire of the French, is afually Fepared. 1 think it impofl lble, by any procefs, to preparv- from the commoxI agaric a f1lb_ Rance pErfeEcly fimilar to e lirench agaric, which exadly anfwers the defcriptiorb which Breynius gives of the Fuags cortacess qaerctnus h6amaodes, and of whhich we fi^d the- fo}lowng * account in the Ephe- merides naturw curxoJsorum.

[ 8I2 ] ' alute ex pelle caprina confeEtf fimxlior quam 4' ovum wo, nifi quod crafl liors materia mxnus com ¢' pada; irtus prz$erea pa{Elm duriuScula & rotunda ^' tubercula, in manus magis quam in oculos inter- Ct currentia occuldtante. Initio guRatus vis Ilatim ' quadam attradriva apparebat. Reperitur et in aliis <' arboribus." Breynius further fays, that this vege- table has been recommended as a mof} excellent re- medy to kop the bleeding at the nofe.

Mr. Ray, in his zSynopAsftrpi Britannicarum, upon the authority of the late Dr. William Sherard, fays, that this F2ngus soriarevs querrintgs harmatodes is found upon putrid oaks in Ireland, where it is called oak-leather; and that the country pEople there colledc and preferve it to drefs ulcers with. Dr. Sl^rard makes no doubt but that it may be found in England; and Mr. Ray had even fome fent him from tbe late Dr. Eales in Hertfordffiire. Dr, Richardfon, inYorkShire, found it growlng upon the a}; and Dr. Dillenius further obSerares, that in Vir- ginia it is uSed as leaier, to fpread p}aiiEers 1lpon; and that, befides its being a foft fubilance, fitting eafy upon -the afflided partX it has a healing pro- perty.

Thus much I thought proper to lay before the Foyal Society, in order that thofie members of itX who-correfpond with the French furgeons, may make fome filrther inquiry into the naeure, as welI as the preparation, if any, of this uSeful regetable.
