lighter oils to 143^ C. in the heaviest sample, for the flash point, and 

 to 172^ C. for the burning jDoint. 



We have also made distillations according to the method of Engler 

 of seventeen samples. We have determined the carbon and hydrogen 

 of three representative samples, and have determined the sulfur in 

 six samples. Prof. F. N. Peters, of the Kansas City central high 

 school, has determined the bromin absorption of eight samples. 

 These results will be published in detail in the Science Bulletin of 

 the University of Kansas. The following is a summary of our results : 



Distillation hy Method of Engler. — 300 co. of the crude oil was 

 distilled from a 500 cc. flask, and the fractions noted, as follows : 



Naphthas Boiling below 150° C 0.0 to 12.0 % by volume. 



Kerosenes Boiling from 150' to 300° C 5.0 to 40.5 % by volume. 



Heavy oils Boiling above 300'" C 83.0 to 45.5 % by volume. 



Residue Not distilling in glass 12.0 to 3.0 % by weight. 



The light oil from near Bolton gave 33 per cent, of naphthas and 63 

 per cent, of kerosenes, leaving practically no residue boiling above 

 217° C. 



Determination of Carhon and Hydrogen. — For our determination 

 of carbon and hydrogen we chose three representative samples of the 

 lowest, medium and highest specific gravity, from oils that we col-
