Carbo7iic Acid. — In tliis experiment the apparatus for the analysis of tlie air 

 broke down, and consequently no account was obtained of the amount of carbonic 

 acid entering the box. Before section, however, the whole amount of carbonic acid, 

 which was contained in tlie air leaving the box, was 2.457954 grammes ; whilst, 

 after section, the air yielded 4.41007 grammes of the acid. It is evident, therefore, 

 that there was a decided increase in the elimination of tlie gas following section, 

 although it is not possible to state exactly the amount of such increase.
