Is Death Universal ?

Epistylis, Codoriga, the individual soul-life of the mother 
does not persist in her united descendants, since these, in 
addition to their common functions and feelings, receive 
individual stimuli and perform separate individual funaions. 
1 he offshoots receive from their mother, on fission, merely 
the foundation for their individual bodily and psychic life. 
This simple basis of the new individual life is formed in the 
Metazoa by gemmules, or by germ-cells and spermatozoa. 
The reproduaive cells of the polycellular animals, or 
heteroplastides (Goette), transfer their vitality, like the 
bodies of the monoplastides, from individual to individual 
without an intermediate stage of lifelessness and death. 
They form, however, voluminous masses of other plastides 
for more powerful and varied life-work than can be executed 
by the tiny bodies of the monoplastides. These developed 
working plastides, incapable of reproduaion, can, for the 
most part, still continue to work in their manner when the 
reproduaive plastides have been separated from the body of 
the polycellular animal. Most heteroplastidic animals sur- 
vive, therefore, their aa of reproduaion, whilst the indivi- 
dual existence of the monoplastides must come to an end 
with the aa of propagation, since in them the working and 
the reproduaive substance are identical. 
Morphologically considered the body of the monoplastides 
corresponds to the reproductive cells of the heteroplastides. 
The life of both, however, is very different. Whilst the re- 
produaive cells of the polycellular animals live on in a state 
of inaaion till they are liberated, transmigrate, and develope 
themselves, the monocular animals enter into relations with 
the external world, even with the bodily mass concerned in 
reproduaion, and may evolve for this purpose especial 
organs. The reproduaive plastides contain groups of atoms 
for the formation of all the organs of the body of their 
species. The plastides of individual organs which have 
merely certain limited funaions contain such atomic groups 
only which are suitable for the formation of young plastides 
having the same especial properties (proteaive, motive, 
nutritive, and sentient plastides). 
The reproduaive plastides of the Metazoa receive no 
direa stimuli from without, so long as they have not become 
liberated. Hence they are not worn out. They do not age 
by work like the working-cells ; but as soon as certain 
external stimuli aa upon them after liberation and fecunda- 
tion, they aa in accordance with their inherent properties 
with fresh and full energy. When the reproduaive plastides 
of the Metazoa do not in a certain time become free
