    served can be of but comparative interest to the student of human physiology. For this reason the work of Luciani has done much to further our knowledge of the function of the human cerebellum. He experimented upon dogs and monkeys, animals in which the cerebellum is more closely allied to the human cerebellum than that of pigeons. So early as 1809 Rolando (2) removed portions of the dog’s cerebellum, and several other physiol- ogists studied the mammalia previous to Luciani’s time, but none was able to surmount the tremen- dous technical difficulties necessary, for instance, to remove the whole cerebellum and keep the animal alive for a considerable period after the opera- tion. Luciani (3) showed the immediate symptoms differed very much from those which subsequently developed. If the narcosis is not too deep, and the loss of blood inconsiderable, the more important symptoms which immediately follow removal of the cerebellar cortex, are extreme restlessness ; pleuro- thotonos, the concavity being toward the operated side; tonic stretching of the fore extremity on the homonymous side; clonic contractions of the other three extremities; and spiral twisting of the neck with the head turned toward the well side. Nystag- mus and strabismus are present, the eye of the side operated upon being drawn down and inward,
