PRESERVATION OF ANIMAL SUBSTANCES IN A RECENT STATE.

As the supply of food is always subject to irregularities, the

preservation of the excess, obtained at one time, to meet the deficiency

of another, would soon engage the attention of mankind. At first this

method would be simple and natural, and derived from a very limited

observation, but in the progress of society, the wants and occupations

of mankind would lead them to invent means, by which the more perishable

alimentary substances of one season, might be reserved for the

consumption of another, or the superfluous productions of distant

countries might be transported to others where they are more needed.
