 Our sharpest discrimination can detect no trace of an 

 internal structure, or of a formation from dissimilar 

 parts. As the homogeneous albuminous mass of the 

 body of the Moner does not even exhibit a differen- 

 tiation into an inner nucleus and an outer plasma, 

 and as, moreover^ the whole body consists of a homo-

from the simple increase of a single amceba-like germ or by the
