while,  in  the  feventh  experiment,  another  part  of  the 
fame  body,  where  external  heat  and  cold  can  make  little 
or  no  impreffion,  was  of  the  fiandard  heat.  Although 
we  fhall  find  hereafter,  from  experiment,  that  the  redtum 
is  not  the  warmeft  part  of  an  animal ; yet,  in  order  to 
determine  how  far  the  heat  could  be  increafed  by  ftimu- 
lating  the  conftitution  to  a degree  fufficient  to  quicken 
the  pulfe,  I repeated  the  feventh  experiment  after  the 
man  had  eaten  a hearty  fupper,  and  drank  a bottle  of 
wine,  which  increafed  the  pulfe  from  730  to  87°,  and 
yet  the  thermometer  only  rofe  to  98°^. 
Having  formerly  made  experiments  upon  dormice  in. 
the  fleeping  feafon,  with  a view  to  fee  if  there  was  any 
alteration  in  the  animal  oeconomy  at  that  time,  I find 
amongft  thefe  experiments  the  following  which  appear 
to  be  to  our  prefent  purpofe : but,  that  I might  be  more 
certain  of  the  accuracy  of  my  former  experiments,  I re- 
peated them"  with  my  new  thermometer. 
exp.  viii.  In  a room,  in  which  the  air  was  at  between 
50°  and  6o°  of  temperature,  a fmall  opening  was  made 
in  the  belly  of  a dormoufe,of  a fufficient  iize  to  admit  the 
ball  of  my  thermometer,  which,  being  introduced  into 
the  belly  at  about  the  middle  of  that  cavity,  rofe  to 
8o°,  and  no  higher.
