lie against the lateral lemniscus. In the horse I found this displace- 
ment the plainest: there the reticular cells even lie partly between 
the fibres of the lateral lemniscus. 
In Macropus these two groups are still clearly connected ; in other 
animals, eg. the, rabbit, I found a relationship which is medium 
between the horse and Macropus. 
Figs. 17, 18 and 19 represent sections through the oblongata 
of the horse. The level of the sections is sufficiently clear in the 
drawings. 
The large reticular cells are seen to be split into two groups. 
The ventro-lateral group maintains its position against, and in, the

the lateral lemniscus lies more dorsally in the section, the reticular 
cells also lie more dorsally in that section (cf. Figs. 18 and 19). 
In figs. 18 and 19 [ have indicated the boundary of the nuclei 
pontis by a dotted line. In the vicinity of the raphe a bulging of 
the nuclei pontis into the oblongata can be seen on fig. 18, indi- 
cated by the dotted line. In the horse, the cells of this group cannot 
be sharply defined from the other cells of the ne. pontis. In some 
animals, however, e.g. thé rabbit and especially Phocaena, the cells
