the Annals and Magazine of Natural History (third series) 4 (1859): 81-90, 175-84. Bronn argued for a gradual appearance of new species and an extinguishing of more primitive ones over great periods of time. Such evolution did not involve, however, the transformation of one species into another, merely the successive appearance and adaptation of progressively higher kinds of flora and fauna. This process occurred, he strongly implied but did not expressly say, through Divine Wisdom. His views were not unlike those of Louis Agassiz and Richard Owen. For a discussion of the ideas of these latter thinkers, see Robert J. Richards,
