Balance of Energy. 



A comparison of the energy derived from different sources with the total 

 heat production for the 4 days of the experiment is given in table 160. The 

 agreement is not very satisfactory save on the first day, but owing to the 

 compensating discrepancies the average difference for the whole experiment is 

 but 0.8 per cent.
