The 02-absorption and the C02-elimination are here expressed in cc. per min., 

 reduced to 0° C. and a barometric pressure of 760 mm. 



We see then that both on days with and without alcohol the 

 amount of carbon dioxide given off lowers in the morning, still 

 more so in the alcohol experiments whereas with N. the amount of 

 oxygen remains constant all day, with v. H. tiiis is the case only 

 in the morning. In the afternoon his ox^^gen value is higher on 

 alcoholdays than on the non alcohol-days. 



It is therefore permissible to conclude that in agreement with 

 Atwater and Benedict's ^) researciies the alcohol is not only oxidized 

 (fall of the respiratory quotient COJO^) but also protects other mate- 

 rial from consumption in isodynamic quantity, anjdiow for some 

 hours after the taking in of alcohol, since the amount of oxygen 

 consumed remains constant. With v. H. however the oxygen values 

 are invariably a little higher in the afternoon on alcokol-days than 

 in the control experiments. It is extremely difficult to account for 

 this. If from the low respiratory quotient we should infer that the 

 alcohol has not been entirely oxidized (with N. also the respiratory 

 quotient was in the afternoon somewhat lower than the one before 

 the taking in of the alcohol and that on the non-alcohol days) we 

 might assume that after the lunch (which in v. H.'s case was more 

 substantial than the breakfast, though each in itself was about the 

 same every day) the metabolism is increased even more through the 

 influence of the alcohol than under the influence of the meal alone. 

 This tallies with our experience that in non-alcohol experiments also 

 V. H.'s oxygen values were higher in the afternoon than in the 

 morning.
