The following list embraces the whole of the oils, fats, and waxes ordinarily met with in commerce. Such of them as are of considerable importance are indicated by an asterisk, and notices of these will follow or be found under their own headings, or under the name of the pro ducing material. The oils, &c., of local, limited, or other wise minor importance are marked with an obelisk. 1. NON-DRYING OILS. Name of Oil. Source. Yield per cent. Specific Gravity. Principal Use.

Coccus ceriferits Physeter macro- cepltalus Oil Testing. The presence of mineral oils in any fixed oil is easily detected by the process of sapouification, as well as by a Seculiar fluorescence they impart to the mixture. In the saponi- cation test the oil is made into a soap, with either soda or potash, the product mixed with sand, and the whole treated with light solvent petroleum spirit, which extracts the mineral oil. The in crease in quantity of solution over the solvent used is the measure of the proportion of adulterants in the oil. Smell, taste, specific gravity, and viscosity, all to a certain extent give indications of the nature of an oil. The elaidin proof that is, the solidification or non-solidification of an oil under the influence of nitrous acid, and the length of time required for solidifying when such a change ensues is a valuable indication of the nature of an oil ; and similar trustworthy conclusions may be drawn by observing the heat de veloped by mixing one part of sulphuric acid with three parts of the oil to be tested, a test first suggested by Maumene, and elabo rated by Fehling. The colour reactions which result from treat ment with acids of different strengths, mixed acids and alkalis, &c., are the most important tests. The following tabular statement of several such tests is extracted from Schaedler s Technologic dcr Fctte und Ode (Berlin, 1883). The first column shows the colour reactions produced by nitric acid of sp. gr. I 1 18 to 1 20 on equal proportions of oil ; the second the effect of fuming nitric acid of sp. gr. 1 40 to 1 45 on four or five times the amount of oil; the third the colour reaction from the use of sulphuric acid of sp. gr. 1 60 to 1 70 ; and the fourth the effect of a diluted mixture of nitric acid and sulphuric acid on equal volume of oils. In the fifth column is given in hours the time a non-drying oil takes to solidify under the influence of nitrous acid, after which comes the appearance of emulsions formed by treatment with alkaline leys of 1 33 sp. gr. The last two columns are devoted to the effects produced by a solu-
