small risks to moral purity as may still remain are constantly and wisely
disregarded, and the immoral traditions of the bath now, for the most
part, belong to the past.

The first more highly organized sense to arise on the diffused tactile
sensitivity of the skin is, in most cases, without doubt that of smell. At
first, indeed, olfactory sensibility is not clearly differentiated from
general tactile sensibility; the pit of thickened and ciliated epithelium
or the highly mobile antennæ which in many lower animals are sensitive to
