It produces organic foodstuffs, and at the same time enhances the living conditions of animals. It contributes to environmental protection and helps biodiversity to increase.

Only by conciseness has it been possible to give even a summary of the principles of dietetics within the limit or this pamphlet. Should there appear in places an abruptness or incompleteness of treatment, these limitations must be my excuse. Those who wish to thoroughly study the science of food are referred to the standard work, "Food and Dietetics," by Dr. R. Hutchison (E. Arnold, 16s.). The effects of purin bodies in producing illness has been patiently and thoroughly worked out by Dr. Alexander Haig.

  • B. cereus can produce either a syndrome with a short incubation period— the emetic form, mediated by a staphylococcal type of enterotoxin—or one with a longer incubation period (8–16 h)—the diarrheal form, caused by an enterotoxin resembling E. coli LT, in which diarrhea and abdominal cramps are characteristic but vomiting is uncommon. The emetic form of B. cereus food poisoning is associated with contaminated fried rice; the organism is common in uncooked rice, and its heat-resistant spores survive boiling.

  • After some further kilometres, sodium begins to increase by ion exchange at the expense of calcium, producing a natural softening of the water. Eventually, the available calcium in the water is exhausted, but sodium continues to increase to a level greater than could be achieved purely by cation exchange. As chloride also begins to increase, this marks the point at which recharging water moving slowly down through the aquifer mixes with much older saline water present in the sediments (Figure 4.1).

  • The new century has begun with some of the lowest grain prices in recent memory. From an economist’s vantage point, this is a sure sign of excess production capacity. However, there may be more here than meets the economist’s eye. Natural scientists, many of whom have contributed to this volume, see something very different. They see reason to be concerned about such issues as the overplowing of land and the overpumping of aquifers. They look at sustainable production and see a worrisome fraction of world food output being produced with the unsustainable use of land and water....
