According to this view, it seems probable that at all periods of the earth's history some form of the Protozoa—rhizopods, sponges, or both—predominated greatly over all other forms of animal life in the depths of the warmer regions of the sea. The rhizo- pods, like the corals of a shallo^^'er zone, form huge accumulations of carbonate of lime, and it is pro- bably to their agency that Ave must refer most of those great bands of limestone which have resisted time and change, and come in here and there with their rich imbedded lettering to mark like milestones the progress of the passing Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Thomson, C.
