On standing for a month or more the denser fractions, and espe- 
cially the second, deposited beautifully regular crystals of sulphur. 
These could only have been derived either from the decomposition of 
sulphur compounds while passing through the filter or from sulphur 
existing as such dissolved in the oil. The latter appears the more 
probable, although further investigation is required to settle the ques- 
tion definitely. 
VOLATILITY. 
The volatility of the Beaumont petroleum as compared with oils 
from Noble County, Ohio, and the Pennsylvania pipe line is shown 
by Richardson to be as follows:
