rching ribs springing from it, to construct the large cylinder which we often see now attaching all the rest of a set of works. This has been a very modern discovery; but, prior even to the first man, Nature had cast such a cylinder in every ribbed and vertebrate animal she had made. The cord of plaited iron, too, now used to drag machinery up inclined planes, was typified in the backbone of the eels and snakes in Eden; tubular bridges and hollow columns had been in use since the first bird with hollow bones flew through the wood, or the first reed waved in the wind. Strange that the principle of the Menai Straits' railway bridge, and of the iron pillars in the Crystal Palace, existed is the Arkite dove, and in the bulrushes that grew round the cradle of Moses! Our railway tunnels are wonderful works of science, but the mole tunnelled with its foot, and the pholas with one end of its shell, before our navvies handled pick or spade upon the heights of the iron roads: worms were prior to gimlets, ant-lions were the first funnel makers, a beaver showed men how to make the milldams, and the pendulous nests of certain birds swung gently in the air before the keen wit of even the most loving mother laid her nursling in a rocking cradle. The carpenter of olden time lost many useful hours in studying how to make the ball-and-socket joint which he bore about with him in his own hips and shoulders; the universal joint, which filled all men with wonder when first discovered, he had in his wrist; in the jaws of all flesh-eating animals his huge one-hinge joint; in the graminivora and herbivora the joint of free motion; for grinding millstones were set up in our molars and in the gizzards of birds before the Egyptian women ground their corn between two stones; and the crushing teeth of the hyena make the best models we know of for hammers to break stones on the road. The tongue of certain shell fish--of the limpet, for instance--is full of siliceous spines which serve as rasp and drill; and knives and scissors were carried ab
