Why has the flea been quoted as an instance of insects excelling in muscular power , in proportion to their diminutiveness?

Because it has been known to draw 70 or 80 times its own weight, resist the ordinary pressure of the fingers in our endeavours to crush it, and leap two hundreds times its own length. Hence it is called by the Arabians, " the father of leapers." Supposing the same relative force to be infused into the body of a man six feet high, he would be enabled to leap three times the height of St. Paul's.

The feats of fleas drawing golden chains and coaches have been authenticated. Latreille tells us of a flea which dragged a silver cannon twenty-four times its own weight, mounted on wheels, and was not alarmed when this was charged with gunpowder, and fired off.
