Book excerpt: Excerpt from The Examination of Hydrocarbon Oils and of Saponifiable Fats and Waxes The change of title from "Mineral Oils" of the preceding editions to that of "Hydrocarbon Oils" of the present fourth edition seemed necessary for several reasons. The term "Mineral Oils" includes in a narrow sense only petroleum products but in a somewhat wider sense may include lignite-tar oils and shale oils. There is, however, some doubt whether the coal-tar oils, discussed even more fully than in previous editions, could be called mineral oils. Moreover the previously included light and heavy rosin oils, turpentine oils and pine oils certainly cannot be classified as mineral oils. Since the appearance of the third edition in November, 1909, important work concerning gas oils, oils for Diesel motors, the theory of lubrication, etc., has been published and this, together with the newer specifications for gas oils, Diesel motor oils, etc., resulting from the work of Spiegel, Hempel and Rieppel, had to be considered in connection with many other specifications. Furthermore all the newer recognized contributions of theoretical interest or analytical value have been carefully gone over. There have been added new sections on the determination of fuel value, on the physiological properties of petroleum products, on the nomenclature of bitumens, etc. Numerous tables of physical constants have been introduced to avoid as much as possible the necessity of reference to other books. The chapters on coal tar, asphalt and its substitutes, ozokerite and several chapters on the fat industry, notably on hardening of oils, glycerine, varnish, etc., have been enlarged. In general, in order to avoid uncertainty in the mind of the analyst, it has been the aim to describe only such methods as have been found useful in, or have been tested by, the Royal Bureau of Testing Materials, or such processes as may be considered trustworthy through the experience of others.
