There is evidently an appreciable variation in the composition and 

 properties of the oils from different points in the Ohio field. Marked 

 differences occur in the specific gravity as well as in the percentages 

 of carbon, hydrogen, nitrogen, and sulphur. 



The oil that was employed in this examination was somewhat 

 heavier, with a specific gravity 0.8380. These results show an ap- 

 preciable variation even in different portions of the same field. A 

 similar variation in specific gravity has been observed in other fields : —
