You know that man is but a poor chemist in his laboratory, as compared with a plant. Take a spire of wheat, expose it to the action of carbonic-acid gas and ammonia, --that little plant takes up those elements in the most marvellous way, and converts them to its own use in its wonderful laboratory; and, lo! there is the cellulose, the oil, the starch, the sugar, the albumen, and fibrine; and those little plants are doing this in every moment of their existence, for the use of man and the animal kingdom.

If you doubt that, pitch a log of wood and a dog into & stagnant pool: the dog, in a very few days, becomes in such a state that you would not like to come near him, while the wood may lie for years before it becomes decomposed. We intercept, then, as it were, the elements of animal bodies while they are undergoing these changes. There are skins: we throw tannic acid onthem during their change, and they become leather; and there is the fatty matter, of which we make soap: we catch hold of these substances while the chemicalchange is going on in them, and we employ them and turn them to a hundred uses in the arts of life.
