The results of the determinations of carbon dioxid and water in the ventilating air current 

 are given in Tables LII-LIV. These statistics are given in detail for the first 3 days of the 

 series and are summarized by days for the following 6 days, in order to serve as a basis of 

 comparison of the results with and without alcohol as a part of the diet. 



Table LII. — Comparison of residual amounts of carbon elioxid and water in the chamber at tlie beginning and end of each 

 period, and the corresponding gain or loss — Metabolism experiment No. 22. 



'In these experiments there was no change in weight of absorbers and there was no drip.
