To quickly assess the difficulty of the text, read a short excerpt:
(c) Resins soluble in alcohol.
(d) Solid asphalt-like substance or substances soluble in ether and not in alcohol; black, pitch-like, lustrous in fracture; 15 to 85 per cent.
(e) Black or brownish-black substance or substances not soluble either in alcohol or ether; i to 75 per cent.

All varieties of asphaltum are wholly or partly soluble in one or more of the following solvents, viz. : carbon bisulphide,... alcohol, ether, chloroform, turpentine, petroleum, naptha, and benzene.
The ingredients which compose asphaltums are present in varying pro- portions in different kinds of asphaltum, and are classified by different authors in many ways.
A convenient mode, and one in frequent use, is a division into petro- lene and asphaltene as proposed by Boussingault. Petrolene he described as an oil ( C 10 H 16 ), separable from asphalt by heating in an oil-bath to 300 C. (572 F. ), asphaltene being the residue.
