Sivu 72 - Their names are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricornus, Aquarius, Pisces; the whole occupying a complete circle, or broad belt, in the heavens, called the Zodiac.
Sivu 226 - If both the places be situated on the same parallel of latitude, their bearing is either east or west from each other ; if the'y be situated on the same meridian, they bear north and south from each other ; if they be situated on the same rhumb-line, that rhumbline is their bearing : if they be not situated on the same rhumb-line, lay the quadrant of altitude over the. two places, and that rhumb-line which is the nearest of...

The beauties of the wilderness are His, That make so gay the solitary place Where no eye sees them. And the fairer forms That cultivation glories in are His.
