And molecular de-velopment inside the earth proceeded as after ages had elapsed the earth opened thethird time. This time a bountiful supply of allclasses and varieties survived. Yet the earth wasalmost covered and the seas almost filled with theshells and bones of the dead. Analogies supporting this theory may be foundin the shape of the flower-buds and fruits of vegeta-tion, particularly in that of seeds and nuts, the ker-nels of which are almost invariably composed of twolobes, which is an evidence of their molecular SNOW CRYSTALS. 191 They may also be found in the animal kingdom be-ginning with the earliest forms of organized life, thefossil remains of which are found inthe rocks, Fig. 37. Sometimes clus-ters of crinoids so closely resemble thefoliage of plants and trees that it isnearly or quite impossible to deter-mine whether*they were a vegetable or an animal organization.

Theirgeneral appearance is much like one of the shapes assumedby molecules, yet there is a great difference ; molecule
