When we have eliminated certain forms of the bath which must
be regarded as luxuries rather than hygienic necessities, though they
occasionally possess therapeutic virtues, we have eliminated the most
violent appeals of the bath to the sexual impulse. So imperative are the
demands of physical purity now becoming, in general opinion, that such
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 antennae which in many lower animals are sensitive to
odorous stimuli are also extremely sensitive to tactile stimuli; this is,
for instance, the case with the snail, in whom at the same time olfactive
sensibility seems to be spread over the whole body.
