36  Mr.  hunter  on  the  Heat , See. 
alfo,  that  the  comb  of  another  cock  had  dropped  intirely 
off,  which  I did  not  fee,  as  by  accident  he  burnt  hirnfelf 
to  death.  I naturally  imputed  this  effect  to  thofe  combs 
having  been  frozen  in  the  time  of  the  fevere  froft ; and 
having,  confequently,  loft  the  life  of  that  part  by  this 
operation.  I endeavoured  to  try  the  folidity  of  this  rea- 
foning  by  experiment. 
I attempted  to  freeze  the  comb  of  a very  large  young 
cock  (which  was  of  a con fider able  breadth)  but  could 
only  freeze  the  ferrated  edges  (which  proceffes  were  full 
half  an  inch  long) ; the  comb  itfelf  being  very  thick  and 
warm  relifted  the  cold.  The  frozen  parts  became  white 
and  hard;  and,  when  I cut  off  a little  bit,  it  did  not  bleed, 
nor  did  the  animal  fhew  any  figns  of  pain.  I next  intro- 
duced into  the  cold  mixture  one  of  his  wattles, 
which  was  very  broad  and  thin;  it  froze  very  readily  : 
upon  thawing  both  the  comb  and  wattle,  they  became 
warm,  but  were  of  a purple  colour,  having  loft  that 
tranfparency  which  the  other  parts  of  the  comb  and  the 
other  wattle  had.  The  wound  in  the  comb  now  bled 
freely. 
Both  comb  and  wattle  recovered  perfectly  in  about  a 
month.  The  natural  colour  returned  firft  neareft  to  the 
found  parts,  increafing  gradually  till  the  whole  was  be- 
come perfectly  found.
