       title: Are the Effects of Use and Disuse Inherited? An Examination of the View Held by Spencer and Darwin

     summary: Nay, we may even have to admit that, in two points out of four, the _inherited_ effect of use and disuse on successive generations is exactly opposite to the immediate effect on the individual. According to Darwin's own views, natural selection _must_ at least have played an important part in reducing the wings; for he holds that natural selection is continually trying to economize every part of the organization.

     summary: The three principal stages of selection, that of {66} _personal_ selection[23] as it was enunciated by Darwin and Wallace, that of _histonal_ selection as it was established by Wilhelm Roux in the form of a struggle of the parts, and finally that of _germinal selection_ We cannot assume that such a coloration has appeared as an _accidental_ variation in just and in only these two species, which fly together with the _Acræa_ in the same localities of the same country and same part of the world--the Gold Coast of Africa.

     summary: On the Pico d'Anna Ferreira it assumes a form to which the name of _H. attrita_ has been applied; when on the Ilheo de Baixo, it is the _H. papilio_; at the Zimbra d'Areia, on the Pico de Conseilho, and in the Ribeira da Coxinha, it is the _H. pulvinata_; and, in many other situations widely removed _inter se_, it puts on the shape (variable, both in size and hue) to which the title of _H. discina_ has been given.
