2 a Mr . hunter  on  the  Heat , fee. 
was  introduced  as  before;  the  quickfilver  at  the  dia- 
phragm was  raifed  to  83°,  in  the  pelvis  only  to  78°. 
Here  the  real  heat  of  the  animal  was  diminilhed  1 6° 
at  the  diaphragm,  and  180  in  the  pelvis. 
exp.  xix.  In  order  to  determine  whether  an  animal 
that  is  weakened,  has  the  fame  powers,  with  refpedt  to 
preferving  heat  and  cold,  as  one  that  is  vigorous  and 
ftrong,  I introduced  the  ball  of  the  thermometer  into  the 
belly  of  the  weak  moufe ; the  ball  being  at  the  dia- 
phragm, the  quickfilver  rofe  to  970 ; in  the  pelvis  to  950 : 
the  moufe  being  put  into  the  cold  atmofphere  as  the 
other,  and  the  thermometer  again  introduced,  the  quick- 
filver flood  at  790  at  the  diaphragm,  and  at  740  in  the. 
pelvis. 
In  this  experiment  the  heat  at  the  diaphragm  was  di- 
minilhed 1 8°,  in  the  pelvis  210. 
Here  was  a diminution  of  heat  in  the  fecond  greater 
than  in  the  firft,  we  may  fuppofe  proportional  to  the 
decreafed  power  of  the  animal  arifing  from  want  of  food. 
To  determine  how  far  different  parts  of  other  ani- 
mals than  thofe  mentioned  were  of  different  degrees  of 
heat;  I made  the  following  experiments  upon  a healthy 
dog. 
exp.  xx.  The  ball  of  the  thermometer  was  inti'o- 
duced  two  inches  within  the  reffum,  the  quickfilver  rofe 
to  1 oo0^  exactly.  The  chefi:  of  the  dog  was  opened,  and 
a wound
