Ether Vibrations.

The effect of movements in the ether depends upon tbe rapidity of the vibrations producing them. The unit of measurement for Bbort waves in the ether is the bicron, which is about one twenty-five millionth of an inch. Waves measuring 380 to 810 bicrons affect our sense of sight, the former number giving violet and the latter red color. The Invisible rays, to which the actinic and Roentgen rays belong, are shorter and have been measured as short as 100 bicrons. Ether waves longer than those giving light give the feeling es warmth. Tbe longest heat waves are eight times the length of those of the red rays, or one three hundred and fiftieth of an inch.
