It is told of the "Spectator," on his own high authority, that having "read the controversies of some great men concerning the antiquities of Egypt, he made a voyage to Grand Cairo, on purpose to take the measure of a pyramid, and that, so soon as he had set himself right in that particular, he returned to his native country with great satisfaction." My love of knowledge has not carried me altogether so far, chiefly, I dare say, because my voyaging opportunities have not been quite so great. Ever since my ramble of last year, however, I have felt, I am afraid, a not less interest in the geologic antiquities of Small Isles than that cherished by "Spectator" with respect to the comparatively modern antiquities of Egypt; and as, in a late journey to these islands the object of my visit involved but a single point, nearly as insulated as the dimensions of a pyramid, I think I cannot do better than shelter myself under the authority of the short-faced gentleman who wrote articles in the reign of Queen Anne. I had found in Eigg, in considerable abundance and fine keeping, reptile remains of the Oolite; but they had occurred in merely rolled masses, scattered along the beach. I had not discovered the bed in which they had been originally deposited, and could neither tell its place in the system, nor its relation to the other rocks of the island. The discovery was but a half-discovery,--the half of a broken medal, with the date on the missing portion. And so, immediately after the rising of the General Assembly in June last [1845], I set out to revisit Small Isles, accompanied by my friend Mr. Swanson, with the determination of acquainting myself with the burial-place of the old Oolitic reptiles, if it lay anywhere open to the light.
