Note 4 — ANTS AND SOME OTHER INSECTS.

It is not without interest to compare these facts with Condillac’s discussion (Treatise on the Sensations) concerning his hypothetical statue.

But it is different in the case of the topochemical sense of smell in combination with the antennary movements. Here Condillac’s conditions of the gustatory sense are fulfilled.
