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...
Sivu 54 - Our views of Nature, however imperfect, serve to represent to us, in the most sensible manner, that mighty power which prevails throughout, acting with a force and efficacy that appears to suffer no diminution from the greatest distances of space or intervals of time...

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. He sets the bright procession on its way, And marshals all the order of the year ; He marks the bounds which winter may not pass, And blunts his pointed fury ; in its case, Russet and rude...
