1799 Med. & Physical Jrnl. 1 277 Dr. Fricke's scintillometer consists of a metal cylinder..which lies insulated upon a pedestal, in a horizontal direction: it is divided into inches, and may be slided backwards and forwards. On one extremity, this cylinder is provided with a brass globe..on which the sparks strike from the conductor: the other extremity is provided with a ring... As the symptoms of the tape-worm usually begin with severe tension..about the region of the stomach. the first sparks are directed through the pit of the stomach.

1861 C. Knight Eng. Cycl.: Arts & Sci. VIII. 460 M. Arago has contrived three methods, or instruments (scintillometers, as he calls them), based upon the change of the central spot from dark to light, which occurs the more frequently in proportion as the scintillation is strong.
