Besipes the division into the three kingdoms of 
nature, (§ 2), natural bodies may with propriety be 
arraneed under two chief classes, organized and un-

which are composed of heterogeneous particles, 
either chemically or mechanically combined, and 
which are formed, even when they are of some rfe- 
eular figure, by external apposition. Organized 
bodies, on the contrary, are all those, which are re-

vans, which, in the natural and healthy state, are 
of the same structure in all the individuals of one 
species. ‘They grow larger, not by apposition, but 
by an internal power, acting from the interior parts

cannot exist without that internal power which is 
necessary for its total formation, subsistence and pro- 
pagation, and which is called Life,
