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.

Studying glacial drift in NW. England, he finds evidence of intense glacial activity, but the molluscan fauna does not appear to indicate a low sea temperature. Requests information on Tierra del Fuego molluscs for comparison.
