Σελίδα 6 - The circumference of every circle is supposed to be divided into 360 equal parts, called degrees; and each degree into 60 minutes, each minute into 60 seconds, and so on.
Σελίδα 7 - The space between the Tropic of Cancer and the Arctic Circle is called the North Temperate Zone, and that between the Tropic of Capricorn and the Antarctic Circle is the South Temperate Zone.
Σελίδα 7 - ... with the sea or ocean. If a gulf be very large, it is called an inland sea ; as the Mediterranean : if it do not go...
Σελίδα 39 - PROBLEM III. — To find the declination of the sun or stars. Rule. — Bring the sun or star to the brazen meridian ; and then its distance in degrees from the equator is its declination. Ex. — Thus, the sun's declination, April 19, is 11° 19
Σελίδα 10 - ... that young people were confounded when they compared it with the earth's positions during its annual rotation round that luminary, and considering the horizon as the boundary of day and night. Being, therefore, sometimes obliged to rectify for the place on the earth, and sometimes for the sun's place in the ecliptic, the two rules clash so unhappily in the pupil's mind, that few remember a single problem a twelvemonth after the end of their tuition.
Σελίδα 41 - Fix the quadrant of altitude, as in the last problem, letting it cut the longitude given on the ecliptic ; then seek the latitude on the quadrant, and the place under it is the place sought. Ex. — Thus, if I am asked what part of the heavens that is, whose longitude is 60° 30', and latitude 5° 30' south, I find it is the place which Aldebaran occupies.
Σελίδα 41 - To find any place in the heavens by having its latitude and longitude given. Rule. — Fix the quadrant of altitude, as in the last problem, letting it cut the longitude given on the ecliptic ; then seek the latitude on the quadrant, and the place under it is the place sought. Ex. — Thus, if I am asked what part of the heavens that is, whose longitude is 60° 30', and latitude 5° 30...
Σελίδα 29 - Make the elevation of the pole equal to the latitude of the place ; find the sun's place in the ecliptic, bring it to the meridian, and set the index to 12.
Σελίδα 10 - Ike earth, instead of the sun's place in tha ecliptic; which put the globe into so unnatural and absurd .a position, respecting the sun, that young people were confounded when they compared it with the earth's positions during its annual rotation round that luminary, and considering the horizon as the boundary of day and night. Being, therefore, sometimes obliged to rectify for the place on the earth, and sometimes for the sun's place in the ecliptic, the two rules clash so unhappily in the pupil's...
Σελίδα 9 - Simplicity and perspicuity should ever he studied by those who cultivate the young mind : and jarring, opposing, or equivocal ideas "should be avoided almost as much as error or falsehood. Our globes, till of late years, were equipt with an hour circle, which prevented the poles from sliding through the horizon ; hence their rectification was generally for the place on...
