Meanwhile the sting is at work. Three and four times over it is driven into the sides of the Myriapod, who, for his part, opens wide his poison-fangs and strives to bite, without succeeding in doing so, for the front part of his body is held in the stubborn pincers. The hinder part alone struggles and wriggles, coils and uncoils. These efforts are useless. Kept at a distance by the long tongs, the Scolopendra’s poisoned fangs are unable to act. I have seen many insect battles; I know none more horrible than that between these two monstrosities. It is enough to make your flesh creep. A lull enables me to part the combatants and isolate them. The Centipede licks his bleeding wounds and recovers his strength in a few hours. As for the Scorpion, he has suffered no damage. Next day, a fresh assault is delivered. Three times in succession the Myriapod is stabbed, till the blood flows. Then, fearing reprisals, the Scorpion withdraws, as though frightened by his victory. The wounded animal does not strike back and continues its circular flight. This is enough for to-day. I surround the jar with a cardboard cylinder. When darkness is thus produced, they will both keep quiet. What happens afterwards, especially at night, I do not know. Probably the battle begins all over again and further thrusts of the sting are delivered. At any rate the Centipede is much weaker on the third day. On the fourth, he is dying. The Scorpion watches him without yet daring to devour him. At last, when there is no more movement, the huge quarry is cut up; the head and then the first two segments are eaten. The dish is too copious; the remainder will go bad and be wasted. His exclusive taste for fresh meat will prevent the Scorpion from touching it. Though stung seven times and oftener, the Centipede does not die until the fourth day; stung once only, the powerful Lycosa perishes that very instant. Death comes almost as quickly to the Praying Mantis, the Sacred Beetle, the Mole-cricket and other hardy specimens which, if impaled by the collector, would kick and struggle for weeks on the cork slab. Any insect stabbed by the sting finds itself forthwith in a parlous plight; the longest-lived are dead within twenty-four hours; and here we have the Centipedes, pinked seven times over, holding out for four days and perhaps dying from loss of blood as much as from the effects of the poison. Why these points of difference? Apparently they are a matter of organisation. Life is an equilibrium whose stability varies according to the position in the hierarchy. At the top of the ladder, a fall is easy; at the bottom, there is a firm foothold. The finely-organised insect succumbs, whereas the coarser Millipede resists. Is this really the explanation? The Mole-cricket leaves us undecided. He, the boor, perishes just as quickly as do those refined creatures, the Butterfly and the Mantis. No, we do not yet know the secret which the Scorpion conceals in the phial at the end of his tail.
