Էջ 64 - Eng. Min.J., 69, 164. — The sample of slag is dissolved in very dilute nitric acid, and any barium present is precipitated by the addition of a few drops of sulphuric acid. The solution is now made almost neutral with dilute ammonia, and the calcium precipitated by the addition of ammonium oxalate. This precipitate contains no iron or aluminum, and can be washed free from ammonium oxalate, dissolved, and oxidized with standard potassium permanganate solution. The entire analysis may be completed...

Էջ 93 - January. 1897, a grant of money was allotted from the Hodgkins fund of the Smithsonian Institution for the purpose of obtaining meteorological records at heights exceeding 10,000 feet, and no doubt the first application of steam to kiteflying was the winch built by Mr. Fergusson, with ingenious devices for distributing, oiling, and measuring the length of wire. The cumulative pressure of the successive coils of wire finally crushed the drum, and the next apparatus applied the principle of Sir William...
Էջ 98 - During the summer of 1898 the United States Weather Bureau undertook to obtain daily from seventeen stations equipped with kites (situated chiefly in the Mississippi Valley), automatic records at a height of about a mile, with which to draw a synoptic chart of the upper air for forecasting in connection with a similar chart of surface observations. The high-level chart could not be drawn regularly on account of light winds at some stations, but much data concerning temperature gradients were obtained,...
