Note.—If a man could jump as high in proportion as a flea, a leap over the Capitol at Washington would be an easy feat. A flea can draw one hundred times its weight, and so easily tamed are these minute creatures that a trained compa- ny of them was exhibited in New York a few years ago. Through a magnifying- glass they could be seen standing erect, drawing carriages in which were seated.
