 lowing data:

The combustion once commenced is continued till after 

 the fourth minute and ends between the fourth and fifth 

 minutes, but the equilibrium of temperature between the bath 

 and the combustion-chamber is not established until the 

 eighth minute, the time when the variation due to difference 

 between them has become regular (0.010 per minute). 



A table of corrections is formed as follows:
