If we take a few insulated facts, there can be but little connexion between them; but when there is a multiplicity of events disposed in order, by associating them together, the one assists the remembrance of the other, and a strong connecting chain is formed, the links of which can scarcely be broken. The facility of committing these facts to memory is increased by their number.
