In two cases of unilateral affection of the cerebellum (clinical observations) I have noted a reaction which may be of great value in the diagnosis of diseases of the cerebellum, especially for localizing right-or left-sided site of the affection. In both cases I tested the caloric reaction of the vestibular apparatus (Barany) and found a typical, well-developed caloric nystagmus of both sides. The disturbances of equilibrium accompanying the caloric nystagmus were, however, atypical. The disturbances of equilibrium of the apparently healthy side could be influenced by changing the position of the head as above described, but on the diseased side equilibrium was not disturbed. One of these patients fell spontaneously each time in a direction backwards to the right. The right side was the affected side. I syringed the left side, hereupon he fell from head in erect position to the left. In turning the head to the right he fell forward, turning to the left he fell backward; entirely typical symptoms. The vestibular innervation of the left side was undisturbed. I then syringed the right side with cold water. With the head in the erect position he then fell backwards to the right, and this direction was not influenced by the head position. Syringing the right side with warm water caused no change in the direction of the fall, while warm syringing of the left side produced the typical disturbances. The second case probably had a left-sided affection of the cerebellum, showing welldeveloped, spontaneous nystagmus to the left. The patient fell to the left instead of to the right. Hot syringing of the right side produced nystagmus to the right and the typical disturbances in equilibrium. Cold syringing of the left side also produced nystagmus to the right, the pati...
