But I have given astrology considerable attention, and if you will examine with me some observations and calculations that I have made, I think you will be with me in my novel opinion, that this earth may prove to be a sphere and in orbitual motion, with its seven planets, about the sun; its annual progress in its circuit giving us seasons, its diurnal motion night and day! ❋ Unknown (1859)
