A tremor similar incharacter to that of multiple sclerosis hasoccurred from tumor in this region, butit is always unilateral. Tumors of the corpora quadrige:m-IXA, besides the general symptoms, suchas headache, double choked disk, andvomiting, cause ataxia and incompleteophthalmoplegia. The ataxia is similarto that observed in lesions of the middlelobe of the cerebellum. Bruns statesthat the ophthalmoplegia will precede the optic tract is seriously aUected, lateralhomonymous hemianopsia will be pres-ent, and the pupils will not react to lightthrown into the eyes from the side of theblind fields: the hemiopic pupillary re-flex of Wernicke. Tumors of the pons give rise to dis-tinct, but variable, symptoms, dependingupon the size and exact location of thegrowth. A tumor may be situated toone side of the pons and cause decidedpontile symptoms from direct pressure,and if the pons is pushed to one side,.

Tumors of the crfs produce crossedparalysis, hemiplegia on the oppositeside of the body,—including the limbsand lower side of the face,—and paral-ysis of the third nerve on the side onwhich the tumor is located. Hemiana?s-thesia will be present on the hemiplegicside if the fibres on the upper or poste-rior portion of the crus are involved. If against the bony structure, as not infre-quently happens, the indirect-pressuresymptoms on the opposite side of thepons from the seat of the tumor may hevery pronounced. If the tumor is situ-ated in the upper portion of the pons,on one side there will be crossed paral-ysis, and possibly hemiana?sthesia, as intumor of the crus.
