The large cells of this nucleus are scattered about in tliis network of fil)res. some lying quite close to the 25. 362 Undescribed Nucleus Lateral to the Fasciculus Solitarius border of the fasciculus, while others are separated from it by adistance varying from to microns. These nerve cells are appar-ently quite distinct from those scattered among the descending rootbundles of the acusticus, which at this level pass down quite near thefasciculus solitarius. The cells of this nucleus are much larger, ofdifferent shape, and stain more deeply with carmine than the cellsamong the descending root bundles of the acusticus. The cells ofDeiters nucleus first appear in the cross-section of the medulla at a
