A Model of the Nasal Chamber of a 

 White Mouse at Birth 



Ida Merrill and Eugenia Schoonover 



Two models were made by the blotting paper method. In one 



of these the outer portion of the epithelium was taken as the outer 



limit and the lining of the cavity as the other. The other model 



was built from the plates which were cut from the interior of the 



Upper figure model of the cavity, from outside. 

 Lower figure model of epithelium from outside. 



Both figures X40.
