Chemical analysis does not detect any difference in the muscles or fat of animals,they to this test yield the same result—but it does not destroy the belief, that monads, of which they are in so great a measure constituted, vary in the species in each organic body. The colour and flavour of the flesh of poultry, which live on the same food, cannot con- found the genus of those brought up together—a chicken cannot be mistaken for a goose. What, then, can constitute the difference which exists, but that they select from the food qualities adapted to their respective natures?

Certainly not from the decomposition of its sterile surface, for the sun and the atmosphere have no other power over it than to comminute and break it into dust—they do not impart fertility, or contribute to the elements of organic matter. The substance of vegetables is not formed of that which has a mineral organ, for no mineral is food for plants; a more.probable source of its formation is the atmospliere, as it con- tains carbonic gas, which forms the basis of charcoal, but no plant will live, however salubrious the air, if its roots be planted in pure earth and moistened with distilled water; so that the source of vegetable E
