Сторінка 208 - I will call no being good, who is not what I mean when I apply that epithet to my fellow-creatures ; and if such a being can sentence me to hell for not so calling him, to hell I will go.
Сторінка 36 - IF IT could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.
Сторінка 113 - English greyhounds of the best breed, to hunt the hares which abound in that country. The great platform which is the scene of sport is at an elevation of about...
