BEGINNINGS OF LIFE 



These areas were distinguished by their whitish, re- 

 fractive appearance from the slightly fawn coloJr of 

 the contiguous unaltered pellicle. Particles of some 

 kind were obscurely seen within the refractive proto- 

 plasm, and on the following day many of the areas, 

 which had increased in number, showed signs of com- 

 mencing segmentation. This process went on com-

Segmentation of Embryonal Areas into Fungns-germs. ( X 1670.) 



a. First stage of differentiation. 



b. Area almost homogeneous and refractive. 



c. First stage of segmentation, 



d. Area showing more complete segmentation. 



e. Area in which homogeneous refractive products are being 



verted into brownish vesicular Fungus-germs. 

 /, / . One form of germ in different stages of development.
