It is frequently dry and powdery, and more or less mixed with earth. The best asphaltum in these superficial beds lies near the surface; in some places it forms a stratum varying in thickness from a few inches to two feet or more. This stratum consists principally of a dull-black, compact asphaltum, but some of it possesses a pitch-like luster, and here and there it...

Add 5 cubic centimeters of ammonium chloride to the filtrate, heat it to boiling, and precipitate th-3 sulphur as barium sulphate, by adding 5 cubic centimeters of barium-chloride solution while stirring constantly. As soon as the reagent is all added, remove the solution to a warm place, and allow it to stand for at least 4 hours for the precipitate to collect and settle. Decant the clear liquid through the asbestos felt of a Gooch crucible that has been ignited...

Page 267 - All the potash and soda were figured to feldspar. The alumina required for the feldspar was deducted from the total alumina, and the difference was taken as the starting-point from which to figure the kaolinite substance. The difference between the total silica (SiO2) and that required by both feldspar and kaolin gives the quartz and the silica in silicates other than those mentioned.

Page 262 - Now add 5 cc. of hydrochloric acid first diluted with its own volume of water. Warm and add 50 cc. of water, heating till everything is dissolved but a little SiO2. Filter and wash. The filtrate should not exceed 100 cc. If it does, concentrate it. Now heat nearly to boiling and add 5 to 10 cc. of a 10 per cent, solution of barium chloride, previously diluted with 10 to 20 cc.
