THE BEGINNINGS OF LIFE. 



These areas were distinguished by their whitish, re- 

 fractive appearance from the slightly fawn colour 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-
