essential to get the proper kind of milk, but the
utmost care is necessary in handling it. It should, of course, be
as free as possible from every source of contamination, and should
be strained thoroughly as soon as milked. It should then be
bottled, and chilled at once by being placed in cold water, and
after being properly sealed, should be placed in a refrigerator at
a temperature of about 50 deg.F., where it should remain undisturbed
for four hours before the top portion is skimmed off for making the
modified milk.

After the modified milk has been prepared it should be returned to
the refrigerator, where it should be kept until required for
feeding. It is best not to use milk that has been in the
refrigerator longer than twenty-four hours, or at most forty-eight
hours, and then only if kept at a proper temperature. The modified
milk should be poured directly from the receptacle in which it is
kept into the feeding-bottle, and the latter should then be placed
in warm water until its content is milk-warm, at which time it is
ready to be given to the child.

It is highly necessary in feeding infants by the bottle to remember that
cleanliness in everything connected with the process only makes success
possible, and in no particular does this apply with greater force than in
connection with the proper care of the bottle and nipple. In every case
immediately after use they should both be put in water, which should then
be brought to a boiling temperature, and both should then be kept in a
saturated solution of boric acid. The nipple, after being placed on the
bottle, should not come in contact with anything but the infant's mouth.
Bottles that have no neck are much to be preferred to others, as they can
be readily cleansed. There is on the market at the present time a bottle
called the "Hygeia," which possesses the necessary qualifications in a
perfectly satisfactory way.

When children who have nursed at the mother's breast reach the age of
weaning it is of importance to remember that they cannot eat without
digestive disturbances the modified cow's milk of a strength that would
otherwise correspond to their age; they should invariably under such
circumstances begin with a milk prepared by the formula used for a child
several months younger, after which the proportion of milk may be
gradually increased until it is used in a pure sta
