The correspondence in this volume continues to reveal the variety of responses to Darwin's species theory in the second year following the publication of The Origin of Species. Darwin also begins to turn to new "evolutionary" projects that illustrate how the theory could be applied to solving important problems in natural history. The letters also yield important new information about contemporary research.
