bad porter, which vitiating the quality of the milk, no medical
treatment cures the disease, until this beverage is left off or
changed, when it at once disappears.

The nurse should take exercise daily in the open air. Nothing tends
more directly to maintain a good supply of healthy milk, than air and
exercise; and the best wet-nurse would soon lose her milk, if
constantly kept within doors. Sponging the whole body also with cold
water with bay-salt in it every morning, should be insisted upon, if
possible: it preserves cleanliness, and greatly invigorates the health.
United with this, the nurse should rise early, and also be regularly
employed during the day in some little portion of duty in the family, an
attendance upon the wants of the child not being alone sufficient.

An amiable disposition and good temper are very desirable. A violent
fit of passion may exert so peculiar an influence in changing the
natural properties of the milk, that a child has been known to be
attacked with a fit of convulsions after being suckled by a nurse while
labouring under the effects of a fit of anger. The depressing passions
frequently drive the milk away altogether. It is hence of no small
moment, that a wet-nurse be of a quiet and even temper, and not
disposed to mental disturbance.

3. ARTIFICIAL, FEEDING, OR BRINGING UP BY HAND.

Extreme delicacy of constitution, diseased condition of the frame,
defective secretion of milk, and other causes, may forbid the mother
suckling her child; and unless she can perform this office with safety
to herself, and benefit to her infant, she ought not to attempt it. In
this case a young and healthy wet-nurse is the best substitute; but
even this resource is not always attainable. Under these circumstances,
the child must be brought up on an artificial diet "by hand,"--as it is
popularly called.

To accomplish this with success requires the most careful attention on
the part of the parent, and at all times is attended with risk to the
life of the child; for although some children, thus reared, live and
have sound health, these are exceptions to the general rule, artificial
feeding being in most instances unsuccessful.

THE KIND OF ARTIFICIAL FOOD BEFORE THE SIXTH MONTH.

It should be as like the breast-milk as possible. This is obtained by
a mixture of cow's milk, water, and sugar, in the following
proportions:--

Fresh cow's milk, two thirds;
Boiling water, or t
