the bulb as in the raphe. Orally from the motor V nucleus the large 
reticular cells lie almost in the middle of the diameter of the bulbus, 
while in Chelone as in Alligator, a raphe nucleus of small cells also 
occurs in the frontal part of the oblongata we. parvocell. sup. raphes)

Crconia alba. 
| examined only one bird, viz. Ciconia alba, in the study of which 
a series of frontal sections coloured after vaN Gigson was used. 
[ found the reticular cells for the most part agreeing with the 
descriptions, which Caja. gives of these elements in birds. For the 
details, therefore, I refer to his description. L wish to touch merely 
on the following points. 
The large reticular cells do not extend in Ciconia so far caudally 
in the oblongata as they do in the lower animals L have described. 
If the sections in frontal direetion be followed, only smaller reticular 
cells are first seen along the lower border of the fase. long. post., 
and more laterally in the formatio reticularis. Then a few very 
small cells also appear in the raphe. More frontally the reticular 
cells become more numerous and include larger cells. The cells in 
the raphe remain somewhat inferior in size to the more lateral cells 
in the same section; this relative size continues to the level of the 
VIII root-entrance, where giant-cells occur also in the raphe. Con-
