7. Experimental Results on Sulphur. 



Table IV contains the measurements made in the sulphur 

 vapor bath, p' and^ represent the gas thermometer pressures 

 corrected as before, t the resulting temperature, followed by 

 the barometer reading reduced to sea level at lat. 45°, and the 

 boiling temperature reduced to 760 mm pressure.
