her aim, both at the bird and at the branch, being as successful as if
one object only had engaged her attention. It may be added that she

all, she caught the narrow framework between the panes with her hand,
in an instant attained the proper impetus, and sprang back again to

evidence that they will bite severely when irritated, a female
_Hylobates agilis_ having so severely lacerated one man with her long
canines that he died; while she had injured others so much that, by
way of precaution, these formidable teeth had been filed down; but if
