The material on which this preliminary report is based consists of two adult brains which show marked deficiencies in the development of the cerebellum. For descriptive convenience, the brains will be designated and referred to as brain 1 and brain 2. Brain 1 was obtained from dissecting material in 1926, while brain 2 was found recently in an autopsy by Dr. Ernest Scott (Department of Pathology, Ohio State University), who kindly gave us the specimen. The ensuing report will deal briefly with: (1) the literature which has a direct bearing on cerebellar agenesis; (2) case histories, and (3) gross description. The microscopic description of these brains will form the subject matter of a later study.
In this brief review of the literature on cerebellar agenesis, it should be borne in mind that reference will be made only to definite cases of agenesis. There are some cases which have been
