Naturallsts have generally accented
the opinion that ants are not able to
perceive any sounds that are audible
TO human ears. Prof. Weld. of the Iowa
State University, controyerts this opln-

experiments made by him with four
species of American ants. from which
he deduces the conclusion that these
species, at least, are able TO perceive
sounds, but whether they do II hy

that OF shrill whistle. and others.
