The two nuclei which have thus replaced the columns t)f Goll and Burdach are the nucleus triangularis of Schwalbe ( NSc) and the nucleus magnoccllularis of Deiters (ND). The size of these nuclei and their fiber connections with the vestibular mechanism indicates a high degree of organi- zation in the reflex acts connected with balancing. These vestibular nuclei are outstanding features in the section. In their general dimensions they cor- respond with the similar structures of lemur, a fact which would seem to justify the inlerence that the marmosets are as well equipped in balancing.
