What reading level is Astronomical Discovery book?
To quickly assess the difficulty of the text, read a short excerpt:

The sequel must show whether this period is constant, whether the minimum activity 160 ASTRONOMICAL DISCOVERY of the sun in producing spots lasts for one or two years, and whether this activity increases more quickly than it decreases. " Attracted This brief announcement is all that the dis- tention, coverer says upon the subject ; and it is perhaps not remarkable that it attracted very little atten- tion, especially when we remember that it related to a matter which the astronomical world had ...agreed to put aside as unprofitable and not worth attention. Next year, in giving his usual paper on the spots for 1844 he recurs to the subject in the following sentence : " The periodicity of spots of about ten years which was indicated in my summary published last year, is confirmed by this year's observations. " I have added in brackets to the table above reproduced the numbers for 1 844 subsequently given, and it will be seen how nearly they might have been predicted.
Still the subject attracted little attention.
