THE various organic substances furnished by the animal and vegetable kingdoms, which constitute the food of man, are, from the nature of their chemical structure, liable to change and decay; they are also irregular in their supply; hence arises the necessity of storing up the abundance of one season to meet the deficiencies of another. The art of preserving food as much as possible in its original state is therefore of great importance; it has been improved by gradual steps, depending, in great measure, as in so many other cases, on chemical discovery and the diffusion of chemical knowledge among persons engaged in the useful arts; so that, at the present time, the deprivations suffered by our forefathers may be prevented; the commonest articles of food may be enjoyed at all seasons; and even the delicious fruits of our gardens may be made to contribute to our health and refreshment at a season when the trees which produced them are covered with snow. The mariner, too, is not now necessarily confined to salt meats; he may, on the longest voyage, and in the severest clime, as easily enjoy fresh meat and vegetables as when he is in port. The necessity for adopting means for the preservation of articles of food arises from the complicated structure of organic compounds, and their tendency to resolve themselves into simpler or inorganic compounds. Although the comprehensive history of the animal and vegetable kingdoms is written with a very brief alphabet; although the elements which enter into the composition of organic bodies are only carbon, hydrogen, and oxygen--often, but not always, nitrogen--and occasionally minute portions of sulphur and phosphorus; yet their extraordinary powers of combination are such that there appears to be no limit to the number of definite substances which they are capable of producing, each substance having a character peculiar to itself, and often a crystalline form. It is very different with the fifty-eight other members of the list of elements; the compounds which they assist in forming are inorganic, and they are formed by the union of _pairs_ of elements, or _pairs_ of _binary_ compounds.
