«x6  Mr.  hunter  on  the  Heat , See. 
.experiments,  I chofe  to  make  a comparative  one  with  the 
dead  part. 
exp.  vi.  Both  the  living  and  dead  part  being  im- 
jinerfed  in  water,  gradually  made  warmer  and  warmer 
from  ioo°  to  ii8°,  and  continued  in  this  heat  for  fome 
minutes,  the  dead  part  raifed  the  thermometer  to  114% 
while  the  living  could  not  raife  it  higher  than  ioa°£. 
It  was  obferved,  by  the  perfon  on  whom  the  experiment 
was  made,  that,  after  the  parts  had  been  in  the  water 
about  a minute,  the  water  did  not  feel  hot  ; but,  on  its 
being  agitated,  it  felt  fo  hot  that  he  could  hardly  bear  it. 
Upon  applying  the  thermometer  to  the  fides  of  the  liv- 
ing gland,  the  quickfilver  immediately  fell  from  1 180  to 
about  1 04V while  it  did  not  fall  above  a degree  when  put 
clofe  to  the  dead;  fo  that  the  living  gland  produced  a 
cold  fpace  of  water  around 
exp.  vii.  The  heat  of  the  reilum  in  the  fame  man 
was  98°--  exactly. 
In  the  fecond,  third,  fourth,  fifth,  and  fixth  experi- 
ments, we  had  an  internal  cavity,  which  is  both  very  vaf- 
cular  and  fenfible,  evidently  influenced  by  external  heat 
and  cold,  though  only  applied  to  the  fkin  of  the  part; 
(b)  This  might  furnifh  an  ufeful  hint  refpe&ing  bathing  in  water,  wh-.ther 
colder  or  warmer  than  the  heat  of  the  body : for  if  intended  to  be  cither  colder 
or  hotter,  it  will  foon  be  of  the  fame  temperature  With  that  or  the  hod  ; there- 
fore in  a large  bath,  the  patient  lhould  move  from  place  to  place:  and  in  a fmall 
one,  there  ihould  be  a conltant  fuccefhon  of  water  of  the  intended  heat, 
while.
