-
An instrument for the accurate measurement of small differences of height; esp. of the differences in the height of the upper surfaces of two columns of mercury or other fluid, or of the same column at different times. It consists of a telescopic leveling apparatus (d), which slides up or down a perpendicular metallic standard very finely graduated (bb). The telescope is raised or depressed in order to sight the objects or surfaces, and the differences in vertical height are thus shown on the graduated standard.

[Gr.] An instrument used for the accurate determination of differences of level, e.g. the height to which a fluid rises in a capillary tube above the exterior free surface. It consists of an accurately divided metallic stem which can be made vertical by means of three levelling screws on which the instrument stands. On the stem slides a metallic piece carrying a telescope-like the telescope of a theodolite-whose axis can be made horizontal by a level. The telescope is first directed to one object, and moved by a delicate screw till a horizontal wire in the focus of the eye-piece coincides with the image of the object; the stem is then read. The process is repeated for the second object. The difference of the readings is, of course, the difference of the levels of the objects.
