We know that it is appointed for allindividuals once to die, whatever their tribe or family, be-cause hitherto all individuals have died; and geology,by ex-tending our experience, shows us that the same fate awaitson species as on the individuals that compose them. Of theseveral periods of existence which measure animated nature,the briefest is allotted to individuals: species live longer—genera longer still; while above them are orders and classes,the latter the most comprehensive of all.
