PLATE IX. 



Fig. 24 (X 17-5). 



The right lateral wall of the nose of a child about one year. This was 

 stained with a differential stain to demonstrate that the olfactory nerves 

 pass as dark bands within the cords of connective tissue and to show that 

 the plexiform appearance is due, not to these olfactory nerve bundles, as 

 has always been stated, but to the ramification of blood vessels and to the 

 amount and arrangement of the connective tissue.
