Fig. 12 Five sections from the same series as figure 11. In A is shown the 

 root of the nervus terminalis entering the hemisphere behind the olfactory bulb. 

 In B the nerve is almost in contact with the tip of the olfactory bulb and runs 

 close to the dorsal olfactory root. In C the nervus terminalis touches its fellow 

 (compare figure 10 B). In D the section cuts an isolated ganglion on the course 

 of the nervus terminalis. The ventral olfactory is spreading out to its endings. 

 In E the dorsal olfactory courses ventrad over the surface of the medial diverti- 

 ticulum. One of the small bundles of the nervus terminalis is seen with ganglion 

 cells.
