Bergson called his instrument Hydrokomion, or Water Dust Apparatus, and in the accompanying woodcut, Fig. 3, I give an illustration of it. It consists essentially of tVo glass tubes, with capillary openings at one end, placed at right angles to each other. The open end of one tube dips into a vessel filled with the fluid which is to be subdivided, A, while the other, D, is fastened to a caoutchouc tube, about a yard long, having on it two globular or spindle-shaped expansions, one in the middle, b, repre- senting an air reservoir, and the other at the end, c, a pair of bellows. If this latter ball is pressed by the hand, the air in the middle ball is compressed and is forcibly blown through the horizontal tube, d. As the current escapes from the fine orifice of this horizontal tube it passes over the mouth of the other tube, creating in it a vacuum, or a tendency to a vacuum, as a consequence of which, first the air in the tube and afterwards the liquid in which it is immersed rises, and becoming thor-
