COMPARISON OF PLATINUM AND GAS THERMOMETERS. 







95 



From this table it may l>e seen that the initial pressure diminished during the 

 series of comparisons with K.9 hy about 0'05 millim. We have assumed for the 

 reduction of the observations that this diminution was proportional to the time. 

 During the comparisons with thermometer K.8 no sensible diminution of initial 

 pressure was observed. 



Comparisons of the PUttinum Thermometers with Porcelain Gas Thermometer. 

 We give in the following table the values of the initial pressure assumed on each
