As soon as the concluding observation in air of the preceding experiment 

 was completed, the air was withdrawn until the included barometer indicated 

 a pressure of about half an atmosphere ; when the following observations 

 were made. 



The vibrations in this experiment were as follows :

 The vibrations in a rarefied medium reduced 1 



to the same temperature as those in air j
