Summary. A series of analyses of normal stools from healthy breastfed and bottle‐fed infants gave the result that the total dry substance content of the feces was the same in the two groups, whereas the total fat content of the dry feces was respectively 20.7% and 36.7%. The latter finding was rather surprising, as recent investigations reported from America and Denmark have indicated that the total fat output was the same in breast‐fed and bottle‐fed infants. It was very interesting to see that the two groups of children presented an unquestionable difference as to the splitting of fat: In the breast‐fed infants fat was excreted chiefly in the form of free fatty acids and neutral fat, in a considerably lesser degree as soap, whereas in the bottle‐fed infants the soap fraction in the dry feces on an average amounted to 78% of the total fat. The values for ash and calcium contents of the feces for the breast‐fed infants were respectively 8.94% and 1.86%, for the bottle‐fed 23.45% and 9.50%.
