Tables XCVI i<> XCVI 1 1 show the results of carbon dioxid and water in the ventilating air 

 current. These statistics are given in detail for experiment No. 33, in which alcohol formed a 

 part of the diet, and summarized for the other 2 experiments of the series. Similar statistics 

 of the beat measurements are given in Table XtiX.
