Excerpt from On the Effects of Certain Inactive Substances on the Optical Activity of Pinene A current of water at 25°C. was kept continually flowing through the jacket of the tubes and the rotation determined at that temperature. The specific rotation was calculated from the formula, - where was the actual rotation observed, 1, the length of the tube in decimetres, p, the number of grams of solvent to every 100 grams of solution, and d, the density of the solution. The polariscope was one made by Pranz Schmidt and Haensch, of Berlin. The scale could be read to the third decimal place, but I found that the third figure had no significance. Usually a set of readings would agree to within four units in the second place. Such a series, taken at random, is given below.
