    Fat Indigestion Separator cream superinduced this: The centrifuge makes 6,700 revo- lutions per minute. Contrast this with cream of Nature's formation: Fat rises slowly to surface and forms a layer known as cream. Each fat globule, by molecular attraction, is surrounded by a stratum of proteid, this prevents them from uniting with each other. Centrifugalization destroys normal, cohesive attraction of fat globule and proteid; proteid is wanting, fat globules become coherent. Conglomerate fat has difficulty in making the passage of the narrow infant pylorus, and is delayed in reaching secretions for fat digestion. Conglomerate fat is as indigestible as cheese. Centrifugal cream is proteid-free, therefore mineral-free— destitute of growth constituents; vigor and vitality dwindle and die out. Gravity cream contains all the constituents oj milk—3 per cent, proteid. Another cause for fat indigestion is the milk of Jersey and Guernsey cows. Separator cream and the milk of these breeds must not be used for feeding an infant. Gravity cream jrom cows oj average grade, properly modified, is perfectly digestible by the youngest, and most delicate infant. Proteid Woman's, and cow's milk, contain two proteids, albumin and casein. Albumin is not coagulated in the stomach. Casein is coagulated into tough, leathery masses. Albumin forms two-thirds of the proteid of woman's, casein four-fifths of the proteid of cow's milk. woman's milk Per cent. Albumin 1 - 23 Casein 0.59 Proteid 1.82 cow's MILK Per cent.

The infant pylorus is so narrow that it allows only the passage of a small probe, and is surrounded by a protuberant, firm, muscular ring. The non-coagulated, non-coagulable albumin of woman's milk readily [4]
