" Lean Perfons are moil injured by Coition , bc - " caufe it more heats and cools fuch , than others . 
Explanation . ' ] This will not appear to be any tradiction , when it is confidered , that the more a Perfon is immediately heated by any Exercife , the more will he be cooled afterwards ; but whether it hath this Effett more upon lean than fat Perfons , I am not able to determine ; for I believe the Con - fequcnces are rather governed by the Intenfenels of the Aólions at that time , than the Bulk of the Perfon . 
A P H . XXVII . 
" Immoderate Coition immediately renders the " Body lighter , although in the end it diminilhes " Perlpiration \ for it vehemently exercifes both the " Body and Mind ; the Body , by aConculfion of " dl the Limbs ; the Mind , becaufe it loofens that " which is the Bond of Union between Body and " Mind , to wit , the Spirits . 
Explanation . ] The latter Part , although it is no uncommon way of talking , lays me under infupe - rable Difficulties . The former Part is plain , for during the Exercife , the Fluids are more agitated and broke , and a larger Quantity expell'd by foration , upon which the Body is for the prelenc lighter - , but as the fame Aótion alfo weakens the lids , Digeftion afterwards cannot fo well be carried on as before , and therefore the perfpirable Matter will not be fo plentifully difchargca , and confe - quently mull the Body grow heavier .
