The graphic recording of nystagmus for clinical purposes has lagged far behind methods used in audiometry. The audiogram was the supplement of the audiometer and gave a more or less uniform method of detailing the results of hearing tests which the use of tuning forks of different types, employed with varied technics, did not afford. That the graphic recording of hearing tests has played no small part in the upsurge of interest in things audiometric is no less true than the fact that the lack of some practical method of recording nystagmus has held in abeyance the progress of clinical neuro-otology. There have been a deplorable vagueness and lack of uniformity in the reporting of vestibular phenomena. Nystagmus is spoken of as rapid or slow, which tells nothing regarding the number of beats per second; or the amplitude may be described as large or small; yet how can it be
