What reading level is An Introduction to Astronomy Designed As a Textbook for the Use of Students of book?
To quickly assess the difficulty of the text, read a short excerpt:
21=27. 32, the time of the sidereal revolution.
214. The moon's orbit is inclined to the ecliptic in an angle of about 5 (5 8' 48"). It crosses the ecliptic in two opposite points called her nodes. The amount of inclination is ascer- tained by observations on the moon's latitude when at a maxi- mum, that being of course the greatest distance from the ecliptic, and therefore equal to the inclination of the two circles.
215. The moon, at the same age, crosses the meridian at dif- ferent altitudes... at different seasons of the year. The full moon, for example, will appear much farther in the south when on the meridian at one period of the year than at another. The reason of this may be explained as follows. When the sun is in the part of the ecliptic south of the equator, the earth and of course the moon, which always keeps near to the earth, is in the part north of the equator. At such times, therefore, the new moons being projected near the sun, will have great southern declination, as is the case during the winter months ; but, in the summer, when the sun is towards the northern tropic and the earth towards the southern, the new moons run high and the full moons low.
