Extraordinary Muscular Strength of the Bat.
When bats bring forth their young they are obliged to carry them on their backs, as they do not build nests like the birds, the little things hanging fast to their fur during flight. The extrordinary strength of muscle possessed by the bat is shown in the fact that two of the young, which are often born at a birth, weigh two-thirds as much as the parent. Thus, flying at nearly double its ordinary weight, we can fancy the power of this animal, surpassing in proportion the strength of the eagle or condor.
