Viewing the cerebellum, in a broad sense, entirely as a motororgan, Kothmann (23;, and Babinski and Tournay (i) regardit as a collection of centers, capable of being centers arc representative of voluntary or semi-voluntary,automatic or semi-automatic movements which enable the animalto maintain given postures, to walk, and to perform other motorfunctions in a regular and orderly manner.

These are theproprioceptive reflexes of Sherrington. Review of Studies on Cerebellar Localization Since Rynberks work many others have attacked the problemof cerebellar localization—among them Marassini (19), Luna(14), Hulshoff-Pol (11), Binnert (3), Horsley and Clarke (9)and Rothmann (23). Such studies have been continued in manby Barany (2), Mills and Weisenburg (20), and others. Inthe following paragraphs a brief outline is sketched of the resultsobtained from these investigations.
