Actual Size 13X6 mm.] LEVEL THROUGH THE MIDDLE OF THE INFERIOR OLIVE (pIG. I 19) At the level through the middle of the inferior olive (10) it is evident that the unfolding which has occurred in the olivary body is considerable. Not only is there an increase in size, but there is also a tendency for this struc- ture to assume the characteristic outline which identifies it in the higher species. It has, however, little of the convoluted appearance so prominent in the larger simians. It is now possible to recognize the main olive and several.
