Rigor.
〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉 is that swifte and frequent motion,* 1.1 (contrary to Palpitationi,) whose motion is litle, softe, & rare, whiche Ga∣len calleth compounde,* 1.2 as of a cause against nature and of a facultie animall (as of the vertue expulsiue) procurynge a sensible coldnes,* 1.3 and an vnequall and inuoluntary mouing of the whole body, wherin it differeth from Horore (whiche is an vniuersal affecte of the skynne only,) and from Tremore whiche possesseth somme one member,* 1.4 and may by the wil be resisted.* 1.5
But that rigor that is wonte to come on sicke persons, and called Rigor morbosus, is by the opinion of Hippocrates, a certeyne peynfull coldnes,* 1.6 with an vnequall mouinge or shakyng of all the body. This may dyuersly chaunce, euen to whole bodyes as of heate, or of colde, or of a viscouse hu∣more, (to the first coolyng is a remedy, to the second heate, to the thirde concoction or euacuation, or both.) Somtyme of the heryng or seyng of horryble and fearfull syghtes, or noyses, phlegme also bredde without a feuer by idlenes, ill order of diete, and entryng the bathe after dynner: to the olde auncientes vnknowne.* 1.7 And though it be euident, it to come of a natiue heate, yet commeth it also dyuersly, as well of colde viscous phlegme as of whotte and sharpe hu∣mores,* 1.8 and sometyme of a iuyce myxed of heate and colde, as in quartanes, but in mixed compounde feuers, the rigor is neuer vehement. It to chaunce to a weake body, in a cō∣tinuall feuer is an euyl signe: and also when it wyl not at all, or hardly be put away.
