nucleus (fig. 7). Here, too, in several sections ventro-lateral outgrowths 
of the accessorius nucleus are present, which might give the impression 
as if this nucleus in the camel continues directly into the nucleus 
ambiguus. This, however, can be proved not to be the case, since the 
ambiguus shows itself much more ventro-laterally. In a few sections 
both the accessorius nucleus and ambiguus are present’) (fig. 8) and 
their separate character is then easily seen. As the remainder 
of nucleus XI we frontally see a small cluster of cells medial 
from the ventral border of the radix descendens nervi V. The fact 
that the ambiguus in a more frontal plain is also found near this 
border, explains the old theory that the ambiguus is a continuas

little shortened for clearness sake.
