Let us turn over our green-crusted penny. ‘COL. NEM.,’[6] the reverse tells us. The inscription is accompanied by a Crocodile chained to a palm-tree from which hang crowns. It is an emblem of Egypt, conquered by the veterans who founded the colony. The beast typifying the Nile gnashes its teeth at the foot of the familiar tree. It speaks to us of Antony, the Don Juan; it tells us of Cleopatra, whose nose, had it been an inch shorter, would have changed the face of the globe. Thanks to the memories which it awakens, [[6]]the scaly-backed reptile becomes a superb historical lesson.
In this way, the important lessons of the numismatics of metals might be continued for many a day and be constantly varied without departing from my immediate neighbourhood. But there is another science of numismatics, far superior and less costly, which, with its medals, the fossils, tells us the history of life. I refer to the numismatics of stones.
My very window-sill, the confidant of bygone ages, talks to me of a vanished world. It is, literally speaking, an ossuary, whose every particle retains the imprint of past lives. That block of stone has lived. Prickly spines of Sea-urchins, teeth and vertebræ of fish, broken pieces of shells and fragments of madrepores form a conglomeration of dead existences. Examined stone by stone, my house would resolve itself into a reliquary, a rag-fair of ancient things that were once alive.
The rocky stratum from which we extract our building materials in these parts covers with its mighty shell the greater portion of the neighbouring uplands. Here the quarryman has been digging for none knows how many centuries, perhaps since the time when Agrippa hewed Cyclopean blocks to form the stages and the face of the theatre at Orange. And here daily the pick-axe uncovers curious fossils. The most remarkable of these are [[7]]teeth, still wonderfully polished in the midst of their rough matrix and as bright with enamel as in the fresh state. Some of them are formidable, three-cornered, finely jagged at the edges, almost as large as a man’s hand. What a yawning gulf, a jaw armed with such a set of teeth in manifold rows, placed stepwise almost to the back of the gullet! What mouthfuls, snapped up and lacerated by those notched shears! You shiver at the mere thought of reconstructing that awful implement of destruction!
The monster thus equipped as a prince of death belonged to the family of the Squali. Palæontology calls him Carcharodon megalodon. Our modern Shark, the terror of the seas, gives an approximate idea of him, in so far as a dwarf can give an idea of a giant.
Other Squali, all ferocious gluttons, abound within the same stone. It contains Oxyrhinæ (O. xyphodon, Agass.), whose jaws are furnished with curved and toothed Malay creeses; Lamiæ (L. denticulata, Agass.), whose mouths bristle with sharp, flexuous daggers, flat on one side, convex on the other; and Notidani (N. primigenius, Agass.), whose sunken teeth are crowned with radiating indentations.
This dental arsenal, bearing eloquent witness to bygone massacres, can hold its own with the Nîmes Crocodile, the Marseilles Diana or the Vaison Horse. With its panoply of carnage, it tells me [[8]]how extermination came at all times to prune the excess of life; it says:
‘On the very spot where you stand meditating upon a splinter of stone, an arm of the sea once stretched, filled with warlike devourers and peaceful victims. A deep inlet occupied the future site of the Rhone valley. Its billows broke not far from your house.’
Here in fact are the cliffs of the shore, in such a state of preservation that, when I concentrate my thoughts, I seem to hear the thunder of curving billows. Sea-urchins, Lithodomi,[7] Petricolæ,[8] Pholades[9] have left their signatures upon the rock: hemispherical recesses large enough to contain one’s fist; circular cells; cabins with a narrow opening through which the recluse received the incoming water, laden with food and constantly renewed. Sometimes the erstwhile occupant is there, mineralized, intact to the smallest details of his striæ, of his scales, a brittle ornamentation; more often he has disappeared, fallen into decay, and his house has filled with a fine sea-mud, hardened into a chalky kernel.
In this quiet inlet, collected by some eddy from the surrounding sea-bed and sunk to the bottom of the oozes, now turned into marl, there are stupendous deposits of shells, of every shape and [[9]]size. It is a molluscs’ burying-ground, with hills for tumuli. I dig up Oysters eighteen inches long and weighing five or six pounds apiece. One could scoop up from this enormous heap Scallops, Coni,[10] Cytheres,[11] Mactræ,[12] Murices,[13] Turritellæ,[14] Mitræ[15] and others too numerous, too innumerable, to mention. You stand stupefied before the intense vitality of the days of old, which was able to supply us with such a mass of relics in a mere hole in the ground.
