in a geometrical ratio ; thus a new germ arises, deriving all 
its force from the original life energy, the new germ resolving

within itself differing attributes, also differing formativ? 
unctions, with the functional power of coalescing in cycles 
with an ingenerating and coalescing principle; hence is 
gotten singleness of action, directed to a particular purpose, 
as the production of a plastide, a plant, an animal. Dege- 
neration is but senescence presented in a particular form ; 
the decadence or dying out of a particular species is but the 
"7 r St6P a neW formation - The inference to be 
collected from this is that all organic formations, however 
diverse, are but the continuation of the vitality contained 
m the first life-impregnated cell, always reproducing 
and multiplying itself : hence it follows that vital energy 
alone is the undying principle of Nature.* 
Unicellular or multicellular forms, so far as the vital 
energy is concerned, are indistinguishable : then necessarily 
we must have the same life in a single cell as in a cycle of 
cells ; thus vital energy becomes the perpetuation of a 
single function in continuous excitation, and the multiplica- 
tion of organic forms, but the accordant life of the simple 
cell ; therefore the unit of life there presented is equal to 
the whole life phenomena of the world. The question which 
the world of Science asks is— “ Is there more life in the 
adult man than in the infant, in the horse than in the 
mouse, in two mice than in one mouse ? ” The answer 
appears to be contained above, the only differentiation being

as in the vegetable kingdom, when closely and accurately considered the 
monophyletic hypothesis of descent is found to be more satisfa&ory than' the 
polyphyletic hypothesis. J
