^{page 435 note 1} The thin limestone or “cement-stone” at this locality is only about one foot thick. It is a compact and very hard grey stone, showing scarcely a trace of fossils as it occurs unaltered between tide-marks. A little higher up, where it runs into the soil and a recent shell-bed (old beach), it becomes decomposed, especially about the joints, and takes the character of a soft, yellow ochre, that is easily split up with a pocket-knife or needle. The rock is then seen to be literally full of the remains (casts or impressions) of Mollusca and the carapace-valves of Ostracods. The contrast of how much is to be seen in a piece of this rotten stone in comparison with how little in a piece of the unaltered stone is most surprising and very instructive.
