In the upper beds of the silurian, lycopodites are the only terrestrial plants yet found. In the lower old red sandstone we find, added to these, with thallogens, that bear at least the same general character as in the system beneath, minute ferns, and a greatly larger plant, allied to the horse tails. The old-red flora seems to have been an acrogenic flora. Ere passing to the luxuriant car- boniferous flora, I shall make but one remark. The existing jjlants, whence we derive our analogies in dealing with the vegetation of this early period, con- tribute hut little, if at all, to the support of animal life. The ferns and their allies remain untouched by the grazing animals. Even the insects that infest the herbacea of the botanist, almost never injure his ferns. Judging from all we yet know, the earliest terrestrial flora may have covered the dry land with its mantle of cheerful green, and served its general purposes, chemical and otherwise, in the well bal- anced economy of nature ; but the herb-eating ani- mals would have fared but ill, even where it throve most luxuriantly ; and it seems to harmonise with the fact of its non-edible character, that up to the present time we know not that a single herbivorous animal lived among its shades.
