    few days, after other signs of involvement of this region are evident, for example, intense headache, vomiting, and vertigo. Sometimes longer periods of time are required before optic neuritis is dis- covered. In one of my cases with other well marked signs of cerebellar growth there was no neuritis; six months later there was well marked neuritis in one eye and intense papillitis in the other. It not infrequently happens ‘that patients come to ophthalmoscopic examination after the papillitis has already subsided and a postneuritic atrophy is present, or at a period when the swelling of the disc is rapidly disappearing and atrophy beginning. Optic nerve atrophy, without signs of preexisting neuritis, and blindness, unassociated with ophthal- moscopic lesions, have been reported. It is well known that the papillitis of intracranial tumor is sometimes unilateral and that when there is a one sided optic neuritis, or a marked difference between the two sides, it is suggestive of the fact that the cerebrum is the seat of the growth, and, on the whole, in favor of the tumor being on the same side as the excess of neuritis. Less frequently unilateral neuritis occurs in cerebellar tumor. It was noted four times in 164 cases of the Weeks collection. Referring to this point Mr. Gunn* writes as follows: “ Taking the important analysis 3’ Brain, XXI, 1898, p. 335.
