The plants which he cultivates are built up of cells, and each plant is developed from a pre-existing cell or series of cells ; and hence it is not within the range of human power to make a plant from any primary elements, and even did we know perfectly the elementary substances of which a plant is composed, no person could put them together to make a plant. Some persons do indeed believe that, under favourable circum- stances, a plant may be formed of inorganic matter, but their belief is founded upon unexplained phenomena connected with the lower class of plants, and "their speculafions rather partake of fancy than of fact.
