and by N. Zuntz and Berdez ^) indicating that a moderate dose of 

 alcohol (30 — 75 cc) did not or hardly at all change the consumption 

 of oxygen and that accordingly the carbon-dioxide elimination had 

 diminished, because with like oxygen consumption alcohol produces 

 a smaller amount of carbon dioxide than other food stuffs. 



In our researches we experimented on ourselves. We are neither 

 of us teetotalers, nor do we indulge in alcohol regularly. 



In our rest-experiments we proceeded as follows : At 9 o'clock in 

 the morning the subject reclined in an easy chair. A determination 

 with the Zuntz —Geppert apparatus was made of the oxygen-intake 

 and the carbon-dioxide output. The subject then took at one time 

 60 cc of 96 7„ alcohol diluted with 90 cc of water. After resting 

 quietly for 10 minutes he breathed through the valves for another 

 10 minutes; samples of air were then collected for analysis in the 

 burets. This required about 6 minutes, so that in the first alcohol- 

 experiment it took place 20— 26 minutes after the alcohol was taken. 

 An hour afterwards another test was made ; likewise a third at 3 

 o'clock in the afternoon. 



In either case the subject breathed through the valves for 10 

 minutes before the air for analysis was collected. 



In order to compare the results arrived at, alcohol and non-alcohol 

 experiments followed each other alternately, both categories being 

 carried out in precisely the same way, alcohol being exchanged for 

 an equal amount of water.
