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.
