Página 68 - ... the days and nights are equal in every part of the earth. But the next step she takes in her orbit, you see, involves the north pole in darkness, whilst it illumines that of the south. This change was gradually preparing as I moved the earth from summer to autumn ; the arctic circle, which was at first entirely illumined, began to have short nights, which increased...
Página 68 - We shall now follow the earth through the other half of her orbit ; and you will observe, that exactly the same effect takes place in the southern hemisphere, as what we have just remarked in the northern. Day commences at the south pole when night sets in at the north pole; and in every other part of the southern hemisphere the days are longer than the nights, while, on the contrary, our nights are longer than our days.
