HISTORICAL DATA  Dandy, in 1918, first suggested the injection of air into the cavities of the brain for diagnostic purposes, but abandoned the endolumbar for the cerebral method. Since then, however, Bingel, Foerster, Wartenberg, Liberson, Carpenter and others have made use of the spinal method, some of them with the aid of complicated apparatus (Bingel, Wartenberg, Liberson).
