598 METABOLISM 



TABLE II 



TENSION OF AQUEOUS VAPOR IN MILLIMETERS OF MERCURY 



To obtain .the dry barometer pressure, subtract the mm. Hg corresponding to the 

 temperature of the air from the barometer pressure at the time of the experiment: 



TABLE III 



TEMPERATURE CORRECTIONS TO REDUCE READINGS OF A MERCURIAL BAROMETER WITH A 



BRASS SCALE TO 0C. 



Subtract the appropriate quantity as found in table from the height of the barometer. 

 The table is for a barometer with a brass scale, and the values are a little lower (about 

 .2 mm.) than for the glass scale. The corrections for intermediate temperatures can be 

 approximated. 



TABLE IV 



TABLE FOR REDUCING GASEOUS VOLUMES TO NORMAL TEMPERATURE AND PRESSURE 

 The observed volume, when multiplied by the factor corresponding to the temperature 

 and pressure, will give the volume of the expired air reduced to and 760 mm.
