TABLE III. 

 CALIBRATION OF THE GOLD RESISTANCE THERMOMETER. 



111 order to agree with Dewaii, we ought to have found for the 

 resistance of the gold wire at the boiling point of hydrogen 1.70812 

 instead of 2.364 52. Also the further decrease of the resistance found 

 by Dewar ^) in hydrogen evaporating under a pressure of SOniM.is 

 greater than that was found by us. We may reinarlt that this latter 

 decrease of the resistance according to him would belong to a decrease of 

 4 degrees on the gas thermometer, and that we in accordance with 

 Travers, Senter and Jaquerod ^) found a difference in temperature 

 of 6,°3 between the boiling point of hydrogen at a pressure of 

 760 m.m. and of 60 m.m. (preliminary measurements). 



§ 4. Representation of the variation of the gold resifitance by a 

 formula. As to this we refer to what has been said in Comm.
