let of his office in any wise for defaulte of influence of spirites, then opening and closing of the heart fayleth: and then néedes must the beast be stiffeled, as it is séene in Apoplexia, and in other such causes. TREVISA. Apoplexia is an euill, that maketh a man léese all manner féeling. Also the same falleth by hurting of the heart, when the humours be voyded, that should kindly be therein: for so the spirites be voyded, and the at∣traction of the aire hath no place. And it fareth so in sodain smiting of the kind heate into the inner parts of the heart, as it happeneth in fearfull men in let∣ting bloud, that other while sayle and sowne. And so it happeneth of the in∣fection of the lyuer. For corruption of the lyuer taketh awaye generation of cleane pured bloud, that féedeth kindlye heate: and if kinde heate fayle, the spi∣rite vitall sayleth, and consequently the breath particularly or vniuersally is let. And so it happeneth in searching & pear∣cing of the lunges, as it fareth in them that haue the Tisike, in whom the breth straighted, vanisheth awaye by priuie hoales, and is not sufficient to temper the beate of the heart. And so it fareth in all repletion, and specially by sodayne filling of the inner veynes of the body: as appeareth in them that be sodaynlye stiffeled in the water: in whome the pores being let, the breath by a vyolent ouercomming and renting of the inner powers is stopped. Also by great corrup∣tion of the aire as in pestilence time, and in corrupt aire, when the spirite vitall eschewing his contrary, closeth himselfe in the inner parts of the heart, and so be∣ing ouerset with aire that is corrupt, may not rule the heart and other lymmes of the body, but faileth in himselfe, and as it were, sodainly vanisheth alwaye: and then thereof commeth death. Also of in∣fection and corruption of the humors of the breast, and of the breast plate and bone, as it is seen among those that haue the dropsie, pore, scurffe, canker, woolfe, & leprosie. Also by the stopping of the or∣gane & wayes that commeth from the langs, as appereth in them that haue the pirre & stifles, & be putrified and thicke breathed, and other such. Also by speciall corruption of the heart, as by biting of an Adder, or of anye other venemous worme: whole venyme pearcing to the heart, ouercommeth the kindly heat, and so stoppeth the way of the breath. Also by too much refraction of hot aire, as chaunceth in ouer hot stewes or bathe, or in the most feruent heate of ye Sun, that rerefieth & openeth the pores ouer measure, and so maketh too great exhala∣tion and wasting of the kinde heate: and so the colde aire that is drawen in, suf∣ficeth not to slake the heate superfluous, that is not of kinde, and so the breath is let. Also the same chaunceth of the duor colde aire yt draweth together ye brawns and the sinewes of the breast: and there∣by the vertue of breathing is let, as it chaunceth in them that sléep vpon snow. And the same other while chaunceth by stopping of a veyne of the heart, that is called Vena concaua, the holow veyne: when that veyne is stopped and closed, the way of the passage is let, by ye which way and passage, the bloud must go from the liuer to the heart, to féede and nou∣rish the spirite vitall. For when the heate wareth abundaunt, and the humor is withdrawen, the beast is stiffeled: for the breath sufficeth not to coole the hart. And so it fareth by ouerburdening of cholar on of other humors, in the most subtill, veynes of the heart, as appeareth in sharpe seuers, in the which the breath saileth. Also by ouer vyolent strayning of the throte and of the arteries: as we may sée in them that be hanged & stran∣gled, in the which the breath be••••g ••••••∣ped, the heart sodainly burneth 〈…〉〈…〉 beast dyeth forthwith. By these 〈…〉〈…〉 and many other, the vertue, vitall 〈…〉〈…〉 by default of breath. Of the vertue spi∣rituall, commeth wrath, fighting, indig∣nation, spite, and such passions, that arise in brute beastes through mouing of the spirital vertue with vehemencie, & with∣out discretion: but in men such passions be ordred and ruled by a certaine reason of wit. And of the vertue spiritall or vi∣tall, that is said shall suffice.
