712. That should be the treatment if the cuticle has been removed? How
often should the dressing of burns be removed? 713. What may be
necessary when there is much suffering? 714. What is the appearance of
limbs while freezing? How should the circulation be at first
reestablished? What should be avoided?

715. The circulation and sensibility may be restored by rubbing the
frozen limb, with snow, or, when this is not to be obtained, cold
water; but snow is always to be preferred. The fire should be avoided;
and it would be better for the patient to be kept in a cold room, for
a time, where there is no fire, or where the temperature is moderate.

716. When a person is found benumbed with cold, and almost or quite
insensible, he should be taken into a cold room, the clothing removed,
and friction commenced and continued for some time, with _snow_. When
warmth begins to be restored, the individual should be rubbed with dry
flannel, and the friction continued until reaction takes place.

_Observation._ When the toes and heels have been repeatedly chilled,
there may be produced a disease called _chilblains_. This affection is
attended with tenderness of the parts, accompanied with a peculiar and
troublesome itching. The prevention of this disease is in wearing warm
hose and thick shoes of ample size. Bathing the feet morning and
evening is also a prevention of this disagreeable affection. When
chilblains exist, apply cold water, warm camphorated spirits, or
turpentine linament.

treatment should be adopted when a person is benumbed with cold? What
treatment should be adopted when warmth begins to be restored? What is
said of chilblains?

CHAPTER XXXV.

APPENDAGES OF THE SKIN.

717. The HAIRS are appendages of the skin, and, like the cuticle, they
are a product of secretion. They have no blood-vessels or nerves, and,
consequently, no vitality. The hairs take their origin from the
cellular membrane, in the form of bulbs. Each hair is enclosed beneath
the surface by a vascular secretory follicle, which regulates its form
during growth. In texture, it is dense, and homogeneous toward the
circumference, and porous and cellular in the centre, like the pith of
a plant. Every hair has on its surface pointed barbs, arranged in a
spiral man
