Infants with weak digestion and those suffering from various forms of
indigestion have often especial trouble in digesting the fat of milk.
To meet the needs of such there is required a series of formulas in
which the fat is lower than in those already given.

These formulas are obtained from plain milk.

_Fourth Series_

_Formulas from Plain Milk (containing 4-per-cent Fat)_
