Note 12 — Chapter X · BACTERIA AND SANITATION

Milk may be sterilized by boiling, but boiled milk is not digestible nor nutritious. Milk may be Pasteurized by immersing bottles of milk in water which is kept nearly (but not quite) at boiling point (160° F.) for five minutes. But this makes the milk less valuable than fresh milk, and destroys beneficent microbes. Buttermilk has many such microbes, which kill injurious microbes and purify the stomach. Cleanliness, or an aseptic condition, is far preferable to antiseptics.
