   It used to be the fashion to put a second thick covering or "pilch" over the napkin to keep the outer clothes from wet; but this is by no means healthy, as it over-heats this part of the body, and is often a mere excuse for neglecting the frequent changes that should be made, so that the skin is apt to become sodden, and subsequently sore, from damp heat.
