The labouring poor, to use a vulgar expression, seem always to live from hand to mouth. Their present wants employ their whole whole attention, and they seldom think of the future. Even when they have an opportunity of saving they seldom exercise it, but all that is beyond their present neccessities goes, generally speaking, to the ale house.
It does not, however, seem impossible that by an attention to breed, a certain degree of improvement, similar to that among animals, might take place among men. Whether intellect could be communicated may be a matter of doubt: but size, strength, beauty, complexion, and perhaps even longevity are in a degree transmissible. . .
