❧What a Cauterye is, & of the Kindes, & differen∣ces therof. Chap. 1.
HAvinge vvith my selfe resolved & purposed, to vvrite sōvvhat, of the Cauteryes, it is first expe∣dient and necessarye that vve knovve, vvhat a Cauterye is, & hovve manye kindes, and Spe∣cies therbe therof: vvhat theire vse is, on vvhat bodyes, on vvhat disseases vve ought to applye them, and the manner hovve vve shall applye the same.* 1.1 Therfore to vnderstande theire na¦ture, vve must first knovve, vvhat vve by the name Cauterium vnderstande: For it may be vn∣derstoode one tvvo sortes or vvayes, Simplely, and not Simplelye: Symplely, consideringe the instrument, & the Causticke matter, vvhich a∣dureth in anye parte, as Galen, in his sixt of the simples in his 27 Chap. describeth: Not because of the signe vvhich remayneth in the Cauteri∣zed parte, that is because of the little Vlceratio∣ne, vvhich remayneth, therin, vvhen as the Es∣cara is fallen therout: Soe that this vvorde Caute∣rium, in properlye being vnderstoode, can noe othervvise be vnderstoode, then a little Vlcera∣tione, in anye externall parte of the bodye, vvhich throughe the art of the Chyrurgiane, is made therin, throughe some comburent, & ad∣ustive medicamentes, to give issve, & passage to some certayne matter, of some dissease.
VVherfor the differēces, of these Cauteryes,* 1.2 or Vlcerationes, are as it vveare dravvne, from their place, & being, vvheron they are applyed, & also from theire efficient cause. The essence, & beinge of these Cauteryes, cōsisteth in theire forme, & figure, vvherfor some ther are vvhich be rovvnde, some contradictorye, others right, great, smalle, deepe, or not deed: All the vvhich have but one onlye apertiō, or sometimes also tvvo, & is thē called a transforatione, or Seton: And also of all other places, vvheron they may be possiblelye applyed, as on the Heade, in the Necke, Armes, Legges, & finally in all partes of the bodye, vvherone they might be applyed, vvhē onlye the agilitye, or actione of the parte can not ther through be hindered, or hurte: Of their efficiēt cause, vvhich is takē out of the di∣versitye of the matter, vvhich is applyed one a∣nye parte of the bodye, or ingendred in the sa∣me. The matter vvhich continuallye is applyed on the bodye, actuallye combureth,* 1.3 or poten∣tiallye, vvherfore they are called actuall, or po∣tentialle Cauteryes: That vvhich in our body is ingendred, can come through any sharpe, cor∣rodent, or bitinge humors, vvherthroughe the skinne is corroded, bitten throughe, & exulce∣rated, of vvhich vlceratione, may be effected &
