[24] _Mathæus de gradi. & Auicenna locis citatis._ Cap. 3. _Of the kinds of this disease, and first of that wherein the vitall facultie is offended._ [Sidenote: _Affectus corporis vel excretionum vitiæ._] Now I come to the kinds and sorts of this disease, which may bee reduced vnto three principall heades, according as euerie part of the bodie belongeth vnto some of the three principall functions which do gouerne the bodie of man. Not that euerie _Symptom_ in this disease doth hurt some of the three functions, for some are onely molestations or deformities, as sudden Collickes, windie humors, noyses, alteration of colour, &c. But because euerie part may well bee mustred vnder some of these generals: and we doe seldome see any hystericall affect wherein some one or mo of the functions are not affected. These functions as they are distinct in office, so they possesse in our bodies seuerall seats and haue seuerall instruments belonging vnto them. [Sidenote: _Trincauel. li. 4 cap. 24._] [Sidenote: _De partium morbis et symp. lib. 5: cap. 12._] 1 The vitall function which by preseruing naturall heat in a due temperature, maintaineth the coniunction of soule and bodie togither, hath his principall mansion in the heart, and from thence by his Arteries conueyeth vitall spirites vnto euery member. So as without this wee could not liue: and therefore it is accounted the principallest function, because the rest receyue their being from this, and this fayling they must needes all cease. This function is performed by the motion of the heart, and Arteries, which in this affect of the Mother is drawne into consent as it is either diminished, abolished, or depraued. The deprauation of this motion is either when it is too fast and quick, or when it beates disorderly. The pulse in this disease is oftentimes too quicke, although it bee weake withall: but seeing it brings no great offence with it, the patient doth seldome complaine thereof. The greater offence is when it beates disorderly, and keepes no equall nor orderly stroke, but either trembleth and daunceth in the motion, or else is violently impelled: insomuch as it doth not onely remoue ones hande being applied to some part where the Arteries are great and near to the skinne (as lately appeared in a noble Gentleman of this lande now dead) but as _Fernelius_ testifieth, hath sometimes displaced the ribbes, and sometimes broken them through the violent motion of the heart.
