Show TROTTING OR GALLOPING? WhatDo Fish Do, and Seals, .and In-aocts, In-aocts, and Worms? liere Is a problem for people with oharp eyes. As wo all know, a horse when ' walking or trotting advances only one leg of each pair at a time, but when galloping lifts both fore feet together and then both hind feet. Now tho question lH how other animals inanngo this matter. mat-ter. Tho birds, of course, flap both wings together, but which blrdB run and which hop? "We human beings "trot" When wo walk and "gallop" when wo swim that -is, If w. are using the plain breast' nlroko. The dog, however, "trots" for both. Now, do tho amphibious animals ani-mals tho eeals, otters nnd tho real swim like men or like other four-footed creattircs? Thon thero arc tho fish. Ono would rather expect that, as they movo their tails from sldo to Bid, they would flap alternately with the fins, which are their hands and foct. Who can tojl whether they do or not, nnd whether all fish at nil times -follow one rule? By tho way, how does a frog use lis "hands 2" The great anatomist, J3. Ray Lnnkcs-tr.r, Lnnkcs-tr.r, has lntoly pointed out that "while the "thousand legs" such as our common com-mon gaily worm, udvanco two feet of a pnlr together, the centlpcds, which are much like them, do exactly tho opposite; nnd tho swimming worms also alternnto the stroke of each pair of paddles. I doubt if many pcoplo can tell on which syHtem tho caterpillar manages Us dozen or so logs, or whether tho adult Insect walks, ti-ots. paces or gnllops on Its six. How docs the spider use clg'ht? Altogether this Is a largo Held for ob servation, a field, loo, whore anv ono may discover now facts as yet mro-corded, mro-corded, nnd thus add to tho store, of knowlcdgo.-St. Nicholas. |
