ve this warm in dessertspoonfuls every five minutes. Give
two tablespoonfuls, or perhaps only one, of very light food, or milk
and boiling water half and half, every half-hour. This may be done in
smaller portions every fifteen minutes, or in larger quantities every
hour or two hours, according to the state of the digestion. Fruit is a
valuable means of quenching the anaemia thirst, besides being very
beneficial for the blood. Green vegetables and salads are also most
valuable (_see_ Vegetables; Assimilation; Diet; Digestion). As much
fresh air as possible is also to be breathed by the patient. Either
much time must be spent in the open air, or, if strength forbid this,
the room must be thoroughly ventilated. Close air is the enemy of good
blood. We know of many cases cured by this simple regimen. Care must
also be taken to increase the patient's vitality by various means. If
_thoroughly good_ medical advice can be obtained, it should be taken
(_see_ Air and Appetite; Balance, Loss of, etc.)

Blood Poisoning.--(_See_ Blood, Purifying; Sores).

Blood, Purifying.--Fever arising from bad state of the blood may be
treated by careful cooling of the spine and head, with towels _well
wrung_ out of cold water, frequently changed (_see_ Fever). The pulse
in one case so treated was reduced from 130 to 96 by a few
applications. If a sore exists, treat it as in article Sores. If an
eruption in the skin breaks out, cover the surface at night with soap
lather (_see_ Lather; Soap). Wipe that off with weak acetic acid
(_see_) in the morning, and the skin will come right. Let the diet be
simple and cooling (_see_ Abscess; Assimilation; Skin; Sores; Appendix,
etc.).

Blood, Supply of.--To supply good blood in cases where it is lacking,
either from indigestion or low vitality, nothing is better than milk,
diluted with an equal quantity of _boiling water_. It may be less or
more diluted, as the patient's power of digestion is greater or less,
but in all cases half and half can be tried first. This forms a natural
blood supply. Claret, switched egg and brandy, are to be carefully
avoided. _Boiling_ water amalgamates with the milk, and care therefore
must be taken to see that it is really boiling. Give a teacupful of
this every two hours. If the patient is very weak, this may be the only
diet. But often he will be going about work or business, and yet
needing fresh, good blood supply. Then the cupful may be taken every
two hours, in
