oospore—and the same is true for an egg, etc:, the terms being 
different—simply a renewal of the growth of the organism ; an 
from this and other convictions follows the result that the forma- 
tion of an oosphere, although it may take place after an accumu- 
lation of large quantities of food, implies a condition of wearl- 
ness—if the term may be allowed—on the part of the protoplasm 
for the time being. No doubt the molecular energy of the pro- : 
toplasm forming the oosphere, is less than that of the rest of the 
plant for the time being; the access of the antherozoid or male 
protoplasm, however, reinvigorates the sluggish mass, and a 
newed life ensues. This may require some time, however, am 
we may possibly not be far wrong if we imagine that interval to 
be occupied in molecular rearrangements in the mass. _ 
But, although we can sum up the foregoing by saying that, 
after a time, protoplasm requires reinvigorating by the addition 
of fresh protoplasm from another source, it is extremely impro)
