But there were chemist shops, where von Liebieg bought ligroin, a laboratory solvent, to power his machine’s single-cylinder three-horsepower engine.

Varieties or similar products are gasoline, naphtha, rhigolene, ligroin, etc.

For highly volatile liquids, e.g. ether, ligroin, &c., immersion of the flask in warm water suffices; for less volatile liquids a directly heated water or sand bath is used; for other liquids the flask is heated through wire gauze or asbestos board, or directly by a Bunsen.

The term is rather loosely applied to a considerable range of products, including benzine and ligroin.

About 2 g. of nitroso-b-naphthol will dissolve in 15 cc. of boiling ligroin.
