MILK.

2. Improving digestibility.

By skimming, scalding, diluting with charged waters or farinaceous gruels, or by adding alkalines or acids. Addition of salt prevents biliousness.
Bicarbonate of soda prevents mal-fermentation. By the addition of farinaceous gruels milk forms in less dense clots.
By scalding, lactic acid fermentation is restricted. Hot milk soothes mucous membrane, allays a slight throat irritation, increases peristalsis, and tends to produce sleep.

3. Predigesting.

By adding Fairchild's Pancreatin or Pepsin powder, which changes the proteids to albumoses, and if the process is continued long enough, to peptones. If converted to peptones there will be a bitter taste.
Predigested milk is used in extreme cases to bridge the patient over a critical period, and for forced feeding in many hospitals and by many physicians.
According to the best authorities, however, predigested milk has no advantage over ordinary milk. From the fact that the proteids are partially digested, it would seem that a large amount of nutriment could be given in predigested milk; if, however, it is administered in sufficient quantities to supply a large amount of nutriment, one of two symptoms usually appear,—diarrhœa or nausea.
