TILL now it has not been possible to diagnose disease of the otolith apparatus. A short time ago, however, I succeeded in establishing this diagnosis by means of some very simple investigations, and I hope that therewith further developments in the knowledge of the vestibular apparatus will be elaborated. My remarks are based on the following case which came under my observation at the aural clinic in Upsala: — A woman, aged 27, had suffered with headaches for the past year. The hearing, the caloric reaction on each side, and the neurological condition were normal. Rheumatoid thickening of the neck and shoulder muscles was present. For the last fourteen days attacks of giddiness had occurred. My assistant, Dr Karlefors, was the first to observe that these attacks only took place when the patient was lying on the right side. During the attacks there appeared a marked rotatory nystagmus to the right with an upward-directed vertical component—the nystagmus became purely rotatory on directing the eyes to the right, and purely vertical on directing the eyes to the left. The attack lasted about half a minute and was accompanied with great giddiness and discomfort. If, however, immediately after the cessation of an attack the head were again turned to the right, no such phenomenon could be induced, and it was necessary for the patient to lie on the back or the left side for a little while before these results could be again evoked. So far there is nothing particularly new in the observation. Oppenheim, Bruns, and myself described similar attacks of giddiness and nystagmus many years ago — and I have assumed that these were referable to the semicircular canal system. In this particular case, however, I carried out a series of small experiments which led further.
