 roscope) to have produced organized beings that enjoy life, of which the water and the flour were believed incapable: it is thus that inanimate matter can pass into life, or animate matter, which is in itself only an assemblage of motion.

Reasoning from analogy, which the philosophers of the present day do not hold incompatible, the production of a man, independent of the ordinary means, would not be more astonishing than that of an insect with flour and water. Fermentation and putrid substances, evidently produce living animals. We have here the principle; with proper materials, principles can always be brought into action. That generation which is styled uncertain is only so for those who do not reflect, or who do not permit themselves, attentively, to observe the operations of Nature.

The generative of motion, and its developement, as well as the energy of matter, may be seen everywhere; more particularly in those unitions in which fire, air, and water, find themselves combined. These elements, or rather these mixed bodies, are the most volatile, the most fugitive of beings; nevertheless in the hands of Nature, they are the essential agents employed to produce the most striking phenomena. To these we must ascribe the effects of thunder, the eruption of volcanoes, earthquakes, &amp;c. Science offers to our consideration an agent of astonishing force, in gunpowder, the instant it comes in contact with fire. In short, the most terrible effects result from the combination of matter, which is generally believed to be dead and inert.

These facts prove, beyond a doubt, that motion is produced, is augmented, is accelerated in matter, without the help of any exterior agent: therefore it is
