sensitive that one is liable to take cold.

~8. The Proper Temperature of Rooms.~--It is also very unwise for a
person to keep the rooms in which he lives too warm, and to stay too
much in-doors, as it makes him very liable to take cold when he goes
out-of-doors. One who is out of doors in all kinds of weather seldom
takes cold.

~9. Care of the Hair and the Nails.~--The scalp should be kept clean by
thorough and frequent washing and daily brushing. Hair oils are seldom
needed. If the skin of the head is kept in a healthy condition, the hair
requires no oil.

~10.~ The habit of biting and picking the fingernails is a very
unpleasant one, and keeps the nails in a broken and unhealthy condition.
The nails should be carefully trimmed with a sharp knife or a pair of
scissors.

~11. Effects of Narcotics and Stimulants upon the Skin.~--Alcohol,
tobacco, opium, and all other narcotics and stimulants have a bad effect
upon the skin. Alcohol often causes the skin to become red and blotched,
and tobacco gives it a dingy and unhealthy appearance.
