Capable of being extended or shut up like a spy-glass; having joints or sections which slide one within another; especially, in machinery, constructed of concentric tubes, either stationary, as in the telescopic boiler, or movable, as in the telescopic chimney of a war-vessel, which may be lowered out of sight in action, or in the telescopic jack, a screw-jack in which the lifting head is raised by the action of two screws having reversed threads, one working within the other, and both sinking or telescoping within the base—an arrangement by which greater power is obtained.

In zoology: Stalked; mounted on an ophthalmite, stem, or peduncle, as an eye.
