The noble experyence of the vertuous handy warke of surgeri, practysyd [and] compyled by the moost experte mayster Iherome of Bruynswyke, borne in Straesborowe in Almayne ... Item there after he hath authorysed and done it to vnderstande thrugh the trewe sentences of the olde doctours and maysters very experte in the scyence of surgery, as Galienus, Ipocras, Auicenna, Gwydo, Haly abbas, Lancfrancus of mylen, Iamericus, Rogerius, Albucasis, Place[n]tinus, Brunus, Gwilhelmus de saliceto, [and] by many other maysters whose names be wryten in this same boke. ...

¶ Of a woūde in the heed throughe cuttynge / with brekynge of Craney without lo∣synge of substaunce to the inner moost couerynge or superficion ouer the brayne throughe perced Ca. xxx. (Book 30)

SOmtyme suche a woūde wyll haue squyrles or sharpnes / & some wyll not / and they be euen / and yf the wounde haue squyrles that myght prycke and hur¦te the pannycle dura mater / they must be made euen / and as the sharpnes is euen ma¦de with a lenticulare / and with other in∣strumentes / then is she heled in maneras the woūde spoken of in y^e other chaptre.

Therfore sayth Galienus / In the woūde that cometh to the pannycle / and is alone owne rupture or cuttynge w^tout lesynge / so shall you occupy the aforesayd sheres / & that must you do as the wounde is in breg¦mate / that is in the vpper parte of the heed

And to the wounde that is on the fyde of the heed / Galienus desyreth no instrumēt / but sowynge and clensynge with tentys. Here vpon he sayth he hath sene that bone Breg∣matis / & vnder that is the bone tymporaus that is the slepynge bone / that hath a grete clyffe / he touched it not / but he cut alonely of that bone Bregmatis / and so heled the parsone / that he lyued after many a fayre daye. And yf he had lefte that bone Breg∣matis therin styll / it shold anone haue cor¦rupteth that pannycle / or Minrinr / or Mi¦ringa / or the fracture is fistened or porosed ¶ Galienus sayth the cause of y^e cure wher in is none euyll matter / nor vnclene moyst nes / there is no nede to cut of the bone / by∣cause that in the slepe of the heed descendeth no matter. And yf ther ony matter cometh soit is in a good place for to clense. ¶ And the aforesayde Galienus wrought in ano¦ther parsone on the same maner / he was a∣ferede to touche the brayne / bycause of the hardnes of the slepynge bone. Therfore he made none hole thynkynge that the brayne sholde come out through it / and also bycau¦se that through the syde moche explantacy∣on of the noble synewes gooth out.
