Fig. 13 (X •<54). 



Head of a child, about one year. The kiteral wall of the nose and orbit 

 have been removed to show the deeper layers of the mucosa in which lie the 

 nerve bundles. Note the anterior ethmoidal nerve. 



Fig. 14 (X 3.75). 



Lateral wall of the nose of a child about one year. Same as 1.3, enlarged. 

 To show especially the plexiform appearance of the olfactory region of the 

 lateral wall of the nose, which has been interpreted by all workers to be a 

 plexus of olfactory nerves. These cords, however, are formed not only of 

 olfactory nerve bundles, but also of blood vessels and connective tissue, as 

 shown by Figs. 24, 2G, 27. Note also the anterior ethmoidal nerve.
