In Schaedler's Technologie der Erdole l another analysis of 

 Burmese oil is given, and the name of the analyst as H. Vohl. 



The Rangoon oil 3 is here described as follows : " Farbe, griinlich 

 braun ; Geruch, eigenartig, nicht unangenehm ; Consisteur, von 

 Gansefett; spec. gew. 0*885— 0*890/' 



It contains : —

In 1865 Messrs. Warren and Storer 8 examined some samples of 

 petroleum from Burma which they describe as follows : — 



" Upon examination the petroleum was found to be a thick, greasy matter, 

 not sufficiently liquid to admit of being poured from the can which contained it 

 when the temperature of the air was 25°C.,but upon being heated, it flowed readily 

 at 30 — 33 , and became perfectly fluid at 38 — 40° The color of the mass was 

 yellowish green. It emitted the odor common to the purer varieties of native 

 petroleum ; though the odor was but slight and in nowise offensive. The specific 

 gravity of this native petroleum was o* 875 at 29 ." 



When distilled and heated up to 30o°C, 30*46 per cent, of volatile 



product, or naphtha as it is called, were obtained. This naphtha was 



further examined and contained : 



Rutylene, distilling from 170 to 176 

 ? „ „ 180 3 to 184 



Margarylene „ „ 186 to 193 



Laurylene „ ,, 200 to 214 



Cocinylene „ „ 226° to 234 



Naphthaline. 

 It probably also contains Pelargone C l8 H l8 boiling at about 155°.
