Summary
The infinite variety of species which constitute the organized kingdom, possess many common properties, independent of the remarkable differences which they exhibit in their structure and appearance. By attending to these common properties, we shall be able to discover some of the qualities of that principle to which they owe their character, and by which their arrangements are regulated.
All organized bodies consist of Solids and Fluids. The former exhibit the appearance of fibres or laminae, of which cells and tubes are constructed, destined to contain the fluids. These solids and fluids are very differently arranged in the different classes of organized being, although similar in individuals of the same species.
The Characters of the Vital Principle.–When we examine a plant or an animal as near to the origin of its existence as possible, we witness its embryo or germ, small indeed, but possessing a power capable of developing in succession the destined phenomena of existence. By means of this power, the germ is able to attract towards it particles of inanimate matter, and bestow on them an arrangement widely different from that which the laws of chemistry and mechanics would have assigned them. The same power not only attracts these particles and preserves them in their new situation, but is continually engaged in removing those which, by their presence, might prevent or otherwise derange its operations.
