Page 82 - ... bichromate solutions. The bichromate solution is made up of convenient empirical strength, and standardised against a weighed amount of pure dried ammonio-ferrous sulphate. Slightly more than the equivalent weight of the latter salt is then weighed out and dissolved in a litre of water, with the addition of a few drops of sulphuric acid. The solution is transferred to a stock bottle, into which is immediately poured a sufficient quantity of some light paraffin oil to form a layer over the solution,...

Page 166 - As a rule, the coloring-matter was fairly sensitive as an indicator, being changed by from less than i to 2 drops of tenth-normal ammonia. Some of the changes were very sharp, and many of the colors were very beautiful. In some cases the color passed through several stages in going from acid to alkaline, or the reverse. The materials examined could be grouped in four classes : Class I. — Extract...

Page 29 - ... immediate origin to putrefactive changes in the intestine. Kynurenic acid excretion accompanies accelerated proteid decomposition, whether this condition be brought about by starvation, ingestion of large amounts of proteid food, or through the action of drugs (borax, phlorhizin). Similar results follow the ingestion of both animal and vegetable proteids, as well as proteoses ; gelatin, however, does not give rise to kynurenic acid in metabolism, acting precisely like the carbohydrates in this...
Page 116 - Mm.}., 69, 260-262. — This is a straight-line, single-hearth, mechanical reverberatory roasting furnace, 15 X 135 feet, with external fire places. The new feature is the rolling stirrer which turns over the ore and moves it slowly from feed to discharge. It consists of a heavy shaft carried by wheels, 6 feet in diameter, rolling on tracks in the depressed wheel-pits on either side of the hearth. The shaft carries a number of collars on which are mounted projecting V-shaped blades. While travelling...
