Fig. 14, Ciconia alba 
Fig. 14 represents a section passing through the oblongata of 
Ciconia, slightly frontally of the NIT nucleus or through the frontal 
pole of that nucleus'). In this section the connection of the laterally 
situated giant-calls with the raphe cells which are rather smaller, 
‘an be observed. 
CasaL describes on the level of the vagus roots only the giant-cells, 
which lie more laterally in the formatio-reticularis, but neither 
mentions nor illustrates anything of raphe cells on this level. The 
large cells lying lateral from the vagus region are collected by 
him into a separate nucleus and distinguished from the remaining 
more frontally situated cells by reason of a peculiarity in the course 
of the axis cylinders *). 
By my method of research | was not able to find any such, or 
similar, distinction; according to vaN Gibson preparations the reticu-

sull motor Al root-cells, | do not venture to decide. 
*) The cells of his “nucleo magnocellular inf”, i. e. the reticular cells lying 
in the region of the vagus-root, send their axis cylinders for the greater part to the 
contra-lateral bulbus-half, after decussating dorsally in the raphe, while all the 
other more frontally situated reticular cells send the axis-eylinders chiefly caudally 
in the via homolateral (in, or next, the fase, longit. post.) or caudally and fron- 
tally after bifurcation.
