    Notes: [Auszug] THE interesting observation recorded by Dr. C. J. Smithells in Nature of July 26 is not new. During the course of a long series of experiments on ‘metal colouring’ at the Birmingham Technical College about thirty years ago, it was found that copper articles, which had been coloured by immersion ...

    Notes: [Auszug] INVESTIGATIONS of petal-colour inheritance in Lychnis species have resulted in considerable confusion owing to insufficiently precise identification of the forms studied. Numerous authors, from Bartram1 (1699-1777) to Winge2, have found the production of petal-antho-cyanin to be dominant ...

    Notes: [Auszug] A SINGLE red blood corpuscle, illuminated by white light, appears yellow under the microscope. Why does it not appear pink? I have asked distinguished zoologists, physiologists, histologists and authorities on colour-vision, but only one has given even a tentative answer, though all have agreed ...
