It  is  to  be  regretted  that  the  table  could  not  be  kept  more 
fully,  but  during  the  rush  of  business  at  the  time  this  was  im- 
possible. Sufficient,  however,  has  been  collected  in  it  to  justify 
the  conclusions  that  have  been  drawn.  The  chief  points  of 
interest  in  the  table  are — 
1.  The  time  at  which  the  temperature  reached  300° ; 
2.  The  highest  temperature  attained  ; 
3.  The  lowest  point  the  temperature  fell  to  after  it  had 
reached  300° ; 
4.  The  number  of  heatings  it  was  subjected  to ;
