sugar; furthermore, the former is acid in
reaction, while the latter is neutral, or faintly alkaline. It will
be seen, then, that in order to prepare a modified cow's milk that
will approximate that of the human being it is necessary to dilute
it with water sufficiently to cause the albumin to approach in
proportion that of mother's milk, and at the same time some alkali
must be added to neutralize the excessive acidity. Modified milk
prepared, however, from the whole cow's milk, would contain much
less fat than is desirable, so that we must use in making it the
upper third of the whole milk after it has been allowed to remain
undisturbed for a number of hours; in other words, in making
modified cow's milk we use a large proportion of the cream, with a
less amount of the other constituents.

The following table for calculating the proper proportion of milk
to be used at the various periods of the infant's life may be
recommended, as it gives quite as satisfactory results as those
that are more elaborate; it also gives the frequency of feeding and
the proper amounts that should be used. The table was devised by
Dr. C. E. Boynton, of Atlanta, Georgia.

In making calculations from this table it is assumed that the milk
