Now it is clear that a predominance of these forms in succession marked the successive epochs developed by fossil geology; the simple abounding first, and the complex afterwards. Two-thirds of the plants of the carboniferous era are of the cellular or cryptogamic kind, a proportion which would probably be much increased if we knew the whole Flora of that era.
The luxuriant and varied vegetation in the ravine affords a fine field for the botanist. The variety of cryptogamic plants is very great every rock, and the trunk of each tree, being covered with ferns, lichens, and mosses.
This is as broad a panspermic statement as can be made, and is only true of inorganic matter so far as vegetable life is concerned, including such infusorial, mycologic, and cryptogamic forms as may lie so near to the "force vegetative" of Needham as to be indistinguishable from it.
Cryptogamic vegetation would have the advantage over Phanerogamic; Hydrozoa over Corals; Crustacea over Insecta, and Amphipoda and Isopoda over the higher Crustacea; Cetaceans and Seals over the Primates; the civilization of the Esquimaux over that of the European.

It has since been traced to a distance of 45 miles from that point into Gloucestershire and other counties, and is commonly not more than an inch thick, but varies to nearly a foot. Near Ludlow two bone- beds are observable, with 14 feet of intervening strata full of Upper Ludlow fossils. Hooker to be the sporangia of a cryptogamic land-plant, probably lycopodiaceous.
In some dust which was collected on a vessel three hundred miles from the land, I was much surprised to find particles of stone above the thousandth of an inch square, mixed with finer matter. After this fact one need not be surprised at the diffusion of the far lighter and smaller sporules of cryptogamic plants. The geology of this island is the most interesting part of its natural history.
He admits that "evolution," as embracing the idea of "natural selection," can have nothing to do with the vast assemblage of infusorial and cryptogamic organisms, until they assume definitely recurring forms, that is, rise into species and breed true to nature. Then, he agrees with Mr.
Another early member of the Department of Botany, Clara Eaton Cummings, who came to Wellesley as a student in 1876 and kept her connection with the college until her death, as associate professor, in 1906, was a scientific scholar of distinguished reputation. Her work in cryptogamic botany gained the respect of botanists for Wellesley.
In New Zealand, before the introduction of the potato, the roots of the fern were largely consumed; at the present time, I believe, Tierra del Fuego is the only country in the world where a cryptogamic plant affords a staple article of food. The zoology of Tierra del Fuego, as might have been expected from the nature of its climate and vegetation, is very poor.
