What reading level is Popular Astronomy a Concise Elementary Treatise On the Sun Planets Satellite book?
To quickly assess the difficulty of the text, read a short excerpt:
THE ASTEROIDS. 133 When carefully watched some of them exhibit rapid changes in the intensity of their light, sometimes sud- denly increasing in brightness, and again as rapidly fad ing out. These changes have been accounted for on the supposition that these worlds are indeed angular frag- ments, and that, rotating on an axis, they sometimes present large reflective surfaces, and again angular points, from whence but a small amount of light reaches the earth.
As the stars of the smaller magnitu...des are becoming more extensively and accurately charted, tlieir places being determined with great precision, we may antici- pate a large increase in the number of known asteroids during the remainder of the current century, and so forward ; for if so great a multitude has already been re- vealed almost without effort, and nearly ty accident, what must be the result when a systematic scheme of examination shall have been executed, based on an ac- curate knowledge of the places of all the stars down to the twelfth magnitude ?
