Prefaces Fritz Müller’s observations on termites and stingless bees [see 9281].
Comments on J. T. Moggridge’s article on the fertilisation of Fumaria capreolata [Nature 9 (1874): 423].
CD has observed hundreds of primrose flowers cut off their stalks, and conjectures that this was done by birds to obtain the nectar. Asks readers of Nature in England and abroad whether primroses are subject to such destruction in their localities.
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.
