"The most accurate method of determining the specific gravity of a mineral is by the use of a chemical balance. To one beam of the balance is suspended a wire basket which is so arranged that it can be immersed in a beaker of water. The basket is hung in the water and then counterbalanced by weights on the opposite pan of the balance. The mineral specimen to be tested, having been first weighed on the balance in the ordinary fashion, is now placed in the basket under the water and weighed again." — Ford, 1912

"Flat-flame burners, or burners which spread their flame in a broad thin sheet, are of two principal kinds known respectively as "fishtail" and "batwing" burners. The fishtail or union burner has two orifices driller in its surface, which are inclined towards each other at the angle of 90 degrees, so that the issuing currents impinge and spread the flame in a broad sheet." — Encyclopedia Britannica, 1893

"Soft coal is heated in iron retorts at an intense heat. Moisture, volatile matter, and gases are driven off, coke remaining in the retort. The gases are cooled in pipes, and coal-tar condenses. then the gases are passed into a 'scrubber' where they come in contact with water, and here the ammonia dissolves. The gases pass on to be further purified from sulphur compounds by passing through calcium and iron oxides in the purifier, previous distribution as illuminating gas." -Brownlee 1907
