Almost all the values for solids in which Δr⁄r exceeds 1⁄2 were obtained with asafœtida, oil of mace, or the home-made cylinder of gutta-percha and gum ammoniae. Thus, out of 9 values in which D. exceeded 1⁄2 for solids, 7 were found with oil of mace, and out of 16 values in which Rob. exceeded 1⁄2, 10 were found with the home-made cylinder of gutta-percha and gum ammoniac, and 4 with oil of mace. We believe that it is perfectly fair to exclude these cylinders from our final results.And if we do so there is little variation from substance to substance. The odor of asafœtida and oil of mace was very perceptible when the instrument was closed, and the mace would
