To G. H. K. Thwaites 21 March [1860]
Summary
Is pleased GHKT goes a little way with him.
Has rectified in foreign editions of Origin his omission of an explanation of the failure of many forms to progress;
also has discussion of beauty in MS. Does GHKT really believe Diatomaceae, for instance, were created beautiful so that man, millions of generations later, should admire them through a microscope? CD attributes most of these structures to unknown laws of growth; useful structures are accounted for by natural selection.
