nothing elfe requifite to make it wreath and-unwreath it felf, and ta

in well rectify'd fpirit of Wine, and then touching the wreath'd Cylin-

on the avolation of the fpirit, by the great heat, it will re-cwilt it felf 
and thus will it move forward.and backwards as oft as you repeat the 
touching it with the fpirit of Wine; fo may, perhaps, the fhrinking and 
relaxing of the. mufcles be by the influx and evaporation of fome kind 
of liquor or juice. But of thisEnquiry I fhall add:more elfewhere.
