I found the present experiment a very interesting one, from the simplicity of the means, the purity of effects, and the beautiful distinctness of the contrasts. However, I do not give the experiment here for its own sake. The only use of it is to characterize the effects of R and L in the polariscope; and this work it does perfectly. 18. Fourth Experiment.--The angle of incidence about 75, and all the arrangements and procedure as in the first experiment, with addition of the compensator. As the intensity in the polariscope is very faint at the best, all proper means are adopted for increasing it--the room well darkened, the battery in good order, the surface of the mirror fresh, the chink between wedge and core merely wide enough to give a good object, and the initial extinction sensibly perfect. When the light is restored from pure extinction by the operation N, and the compensator is placed and strained as in the third experiment, the light is.weakened by tension and strengthened by compression, and the weakening by tension proceeds to pure extinction. The effect of the operation S is, on the contrary, weakened to extinction by compression and strengthened from first to last by tension. Paragraph omitted. 19. Fifth Experiment.--This is a repetition of the second experiment with addition of the compensator; it is more easily managed than the fourth, and the results are equally convincing. In the first half of the second experiment as already described (10), the three sets of operations applied successively Wei'e (B, N), R, (B, S), and the intensities in the polariscope in the three cases, respectively, were bright, faint, dark. When the effects in the first and second cases are more
