 and 3590-3 : 153-05 : : 100 : 4-262 per cent. 



The average therefore of 32 experiments made before 

 breakfast, and comprising 8 days, appears to indicate 4*262 

 per cent, of carbonic acid gas in the air respired. 



If we correct the above for tension, as per table at page 

 402, it will become about 4-37 per cent. 



N.B. The average correction for tension, computed from
