The stills employed in Russia and Galicia are usually smaller than those already described.
Oils which contain sulphur-compounds are subjected to a special process of refining in which cupric oxide or litharge is employed as a desulphurizing agent.
The earliest form of testing instrument employed for this purpose was that of Giuseppe Tagliabue of New York, which consists of a glass cup placed in a copper water bath heated by a spirit lamp. The cup is filled with the oil to be tested, a thermometer placed in it and heat applied, the temperatures being noted at which, on passing a lighted splinter of wood over the surface of the oil, a flash occurs, and after further heating, the oil ignites.
Before long, however, it was found that the open-cup tests (though they are employed in the United States and elsewhere at the present time) were often very untrustworthy.
For the testing of the viscosity of lubricating oils the Boverton Redwood standardized viscometer is generally employed in Great Britain.

In the manufacture of stearin for candles, &c., the fatty matter is decomposed, and the liquid olein, separated from the solid fatty acids, is employed as an ingredient in soapmaking.
Almost any fatty substance can be employed in soap-making; but the choice is naturally restricted by the price of the fat and also the quality of the soap desired.

This property is usually obtained by mixing soft and hard soaps, or, more rarely, by adding gum tragacanth to a hard soap. In the textile trades the wool scourer employs a neutral olive-oil soap, or, on account of its cheapness, a neutral curd or curd mottled brand; the cotton cleanser, on the other hand, uses an alkaline soap, but for cleaning printed cottons a neutral olive-oil curd soap is used, for, in this case, free alkali and resin are objectionable; olive-oil soap, free from caustic alkali, but often with sodium carbonate, is also used in cleansing silk fibres, although hard soaps free from resin are frequently employed for their cheapness.

Twelve tailors, it is said, were continually employed in making clothes for him, and he wore a new suit every day.
He was last employed in the negotiations for confirming the truce of Andrussowo (September 1669; March 1670).

The bishop also influenced the king's policy with regard to France, Scotland and Wales; was frequently employed on business of the highest moment; and was the royal mouthpiece on several important occasions.
In the earliest mosque at old Delhi, they adopted the piers and bracketed capitals of the Jaina builders, whom they probably employed to build their mosque.
They, however, had no confidence in the arch, which, as the Hindu says, "never sleeps but is always tending to its own destruction," so that the pointed arch, which had almost become the emblem of the Mahommedan religion, had to be dispensed with for the covered aisles which surrounded the great court, and in the triple entrance gateway the form of an arch only was retained, as it was constructed with horizontal courses of masonry for the haunches, and with long slabs of stone resting one against the other at the top. A similar construction was employed in the great mosque at Ajmere, built A.D.1200-1211at the same time as the Delhi mosque.
This won him the confidence of Bonaparte, and he was henceforth employed in drawing up many of the more important documents.
This section treats of the qualitative detection and separation of the metals, and the commoner methods employed in quantitative analysis.
It is really not extraordinary that Isaac Hollandus was able to indicate the method of the preparation of the " philosopher's stone " from " adamic " or " virgin " earth, and its action when medicinally employed; that in the writings assigned to Roger Bacon, Raimon Lull, Basil Valentine and others are to be found the exact quantities of it to be used in transmutation; and that George Ripley, in the 15th century, had grounds for regarding its action as similar to that of a ferment.

1 Approximate values of the atomic weights are employed here.
Thus, the symbols 14 2 and P4 indicate that the molecules of hydrogen and phosphorus respectively contain 2 and 4 atoms. Since, according to the molecular theory, in all cases of chemical change the action is between molecules, such symbols as these ought always to be employed.
Rational formulae of a much simpler description than these graphic formulae are generally employed.
This is also the case if two substances are brought together in solution, by the action of which upon each other a third body is formed which is insoluble in the solvent employed, and which also does not tend to react upon any of the substances present; for instance, when a solution of a chloride is added to a solution of a silver salt, insoluble silver chloride is precipitated, and almost the whole of the silver is removed from solution, even if the amount of the chloride employed be not in excess of that theoretically required.
Many substances were employed in ancient medicine: galena was the basis of a valuable Egyptian cosmetic and drug; the arsenic sulphides, realgar and orpiment, litharge, alum, saltpetre, iron rust were also used.
