Natural selection implies that a form remains unaltered unless an alteration is to its benefit. This is not inconsistent with some forms remaining stable for long periods. Natural selection must at present be grounded entirely on general considerations. Of details we are still greatly ignorant.

J. H. Balfour has arranged a position for him at a Cinchona nursery. Reluctant to take this position in part because of his experiments for CD.
