Side 11 - Things which are halves of the same are equal to one another. 8. Magnitudes which coincide with one another, that is, which exactly fill the same space, are equal to one another. 9. The whole is greater than its part. 10.
Side 140 - On the plate is represented a total lunar eclipse ; the moon being in the midst of the earth's shadow. Now it will be apparent that in the situation of the sun, earth, and moon, as represented in the figure, this eclipse will be visible from all parts of that hemisphere of the earth which is next the moon, and that the moon's disk will be equally obscured, from whatever point it is seen.
Side 11 - Things which are equal to the same thing are equal to one another. 2. If equals be added to equals the wholes are equal. 3. If equals be taken from equals the remainders are equal. 4. If equals be added to unequals the wholes are unequal. 5. If equals be taken from unequals the remainders are unequal. 6. Things which are double of the same are equal to one another.
Side 107 - ANGLE OF POSITION between two places on the terrestrial globe, is an angle at the zenith of one of the places, formed by the meridian of that place, and a vertical circle passing through the other place...

Side 69 - Rectify the globe for the latitude of the place. Bring the sun's place in the ecliptic to the meridian, and set the index at 12.
Side 140 - ... small portion of the hemisphere on which the moon's shadow falls, it happens that for any particular place on the earth, lunar eclipses are more frequently...
