II. A sparingly volatile mineral oil of sp. gr. 0°84 to 0-87, of a es ee 
color, perfectly limpid, almost odorless, never becoming rancid, and suscepti-

inery, and has an a araniag over = and other vegetable oils, or — 
monia. 
IV. From the oils ahd II, and IIT, I extract a red coloring matter which 
can be eh in various 
fit for het candles; this substance does not occur in very large ae 
in the crude oil, and the proportion varies according to the different mineral 
substances upon which I operate. There is but little of it in petroleum, and 
in the oil obtained from bituminous limestone often leave a great part of 
e paraffine in the fat oil and in the grease in order that these may be of 
superior “ ality. 
VI. Grease. This grease is superior to that of animals for lubricatin, 
machinery, and for many ve te rposes, since it does not become rancid, an 
remains unctuous when y ct with metals.
