In  Table  26  it  will  be  noticed  that  the  percentages  of  haemoglobin, 
remaining  undestroy^ed,  have  been  recalculated  in  columns  Sj  9 
13,  from  the  corresponding  values  of  /i,  taken  from  the  last  column 
of  Table  27.  The  difference  between  the  observed  and  calculated 
percentages  is  seen  to  be  inconsiderable,  except  when  destruction  of 
haemoglobin  exceeds  80  per  cent. ;  in  the  latter  case  the  percentages 
cannot  be  estimated  with  much  precision  owing  to  the  escape  of 
haemoglobin  from  the  red  cells.  Table  28  is  introduced  in  order  to 
permit  a  more  ready  comparison  of  the  values  of  K,  found  and 
calculated,  at  individual  temperatures.  The  values  of  n,  obtained  in 
Table  27,  enable  the  lowering  of  the  rate  of  destruction  of  haemo¬ 
globin,  caused  by  variation  of  temperature,  to  be  calculated.  Thus 
a  reduction  of  the  destruction  rate  to  takes  place  if  the  tempera¬ 
ture  is  lowered  from  37°  C.  to  31°  C.  when  /u  =  30,000  and  to
