The total work is automatically indicated by an apparatus provided for that purpose which saves the labor of computation. The speed of the train is automatically recorded by a tracing made on a revolving flat disk of paper, the motion of which, by ingenious mechanism, is made to harmonize with the speed of the train, the ratio between these being a constant. "The time is registered by means of a clock with electrical contacts by means of which a current is sent every ten seconds into a magnet that actuates a pencil." This therefore makes six marks per minute upon the paper band. The mechanism for tracing the datum lines, and effecting the movement of the paper band is ingenious. "The analysis of the products of combustion is effected by two sets of Orsat apparatus placed below the observation seats. The analysis consists of measuring the percentage of carbonic acid, oxide, and oxygen. The residue is supposed to consist solely of nitrogen. A copper tube is suspended from the top of the locomotive chimney, and is connected by an indiarubber tube to a fixed flask into which the gas is drawn by an aspirator. The volume of gas to be analyzed is passed into a graduated tube, and then passed into test tubes containing absorbents. The first tube contains a solution of caustic potash, which absorbs the carbonic acid; the second contains a solution of potassium pyrogallate which absorbs the oxygen, and the third tube, a solution of cuprous chloride which absorbs the carbonic oxide. After each absorption the gas remaining is measured in the graduated tube, and the volume absorbed is the difference between the first and last measurements. The final residue is considered as nitrogen.&q...
