Rapidly changing temperature, not given lull weight in mean. 



For the sake of comparison, these temperatures, reduced to the 

 thermodynamic scale, and those found by Messrs. Day and Sos- 

 man 3 by transfer with thermocouples, and also by direct measure- 

 ment with the gas thermometer in sulfur, are shown below:
