a wound  made  into  the  right  ventricle  of  the  heart,  and 
the  ball  immediately  introduced;  the  quickfilver  rofe  to 
i oi°  exactly.  A wound  was  next  made  fome  way  into 
the  fubftance  of  the  liver;  and  the  ball  being  introduced, 
the  quickfilver  rofe  to  ioo°|.  It  was  next  introduced 
into  the  cavity  of  the  ftomach,  where  it  flood  exactly  at 
ioi°.  All  thefe  experiments  were  made  in  a few  mi- 
nutes. 
exp.  xxi.  The  fame  experiments  were  made  upon; 
oxen;  the  quickfilver  rofe  exactly  to  9 9°^. 
exp.  xxii.  The  fame  were  alfo  made  upon  a rabbit, 
•and  the  quickfilver  rofe  to  99°!. 
From  the  experiments  on  mice,  and  thofe  upon  the- 
dog,  it  plainly  appears,  that  every  part  of  an, animal  is 
not  of  the  fame  degree  of  heat;  and  hence  we  may  rea-- 
fonably  infer,  that  the  heat  of  the  vital  parts  of  man; 
is  greater  than  what  it  is  found  to  be  either  in  the  mouth,, 
the  redtum,  or  the  urethra. 
To  determine  how  far  my  idea,  that  animals  couldi 
have  their  heat  varied  in  proportion  to  their  imperfec- 
tions, is  juft,  I made  the  following  experiments  upon 
fowls,  which  I confider  to  be  one  remove  below  what  are- 
commonly  called  quadrupeds. 
exp.  xxin.  I introduced  the  ball  of  the  thermometer" 
fucceflively  into  the  intejlinum  redlum  of  feveral  hens,.
