Sometimes the female bird is finer and stronger; thus stronger and of more powerful wing-spread in the case of the secretary, the buzzard, the falcon, the ash-coloured vulture and many birds of

edness. The gold-yellow oriole with black wings and tail, has for mate a brown sparrow with grey and greenish touches. The silver pheasant (a false pheasant) has a black tuft standing up from his silver-white nape, his neck and back are of the same metal; his dark belly has a blue shimmer, his beak is blue, his cheeks red, and his feet, red. The smaller female covers her belly sadly in a whitish chemise, her back is russet. In the true pheasant the dimorphism is still more marked. The large, proud male (we are dealing with the common pheasant) who has no objec

the direct consequence of the possession of sexual organs, castration inclines the male toward the female type.[3] This is as apparent in cattle as in eunuchs or gelded horses. One may see in this yet another proof of the primitivity of the female, since the abstraction of testicles suffices to give the male that softness of form and character which typifies females. Masculinity is an augmentation, an aggravation of the normal type represented by femininity; it is a progress, and in this sense i
