Thanks Nature correspondents for their observations on destruction of primroses [Nature 9 (1874): 509; 10 (1874): 6–7]. Reports an error in his observations: ovules, as well as nectar, are taken by the birds. As the habit of cutting off primrose flowers is widespread, CD concludes it is instinctive in bullfinches.
Darwin consents to his correspondence with Pieter Harting being published in Nature.
