A good deal has been written on the relation of the total brain weight to that of various of its component parts, both in the normal person and in different varieties of dementia, but comparatively little has been recorded with respect to these relations in epilepsy. Yet the problem seems not unpromising when one considers the frequent presence of paroxysmal ataxia in this condition and the fact that a reduction in the weight of the brain below normal has been reported by several observers.1
The total brain weight of the cerebellum and the proportion between it and that of the cerebrum for various races have been reported by Weisbach2 in table 1.
In table 1, we have summarized the total number of cases studied in the various races included and the average for the total brain weight, the cerebellar weight and the proportion existing between the two. In
