To quickly assess the difficulty of the text, read a short excerpt:
I purposely asked for xvi Introduction to Tables for books of date near the end of a year because the star-corrections are then largest (owing to the effect of precession) and discrepancies would be also largest. Taking the first 100 stars in one of these books, and restricting the logs, to three figures, and comparing the results with those obtained previously, I find differences in Declination corrections as follows : Error. Number Error. Number of cases. Of cases. 0-05 i +0-01 5 0-04 6 + 0-0...2 9 0-03 u 4-0-03 6 0-02 ii +0-04 3 o-oi 32 +0-05 i o-oo 15 Total .... 100 The small systematic error previously mentioned is conspicuous in this example. Many of the star-corrections about this period have values near 20", and the errors are thus grouped about a mean somewhere near o"oi. Also it will be noticed that about half the errors (viz. , 52 out of 100) are less than o"-O2. It would perhaps be fairer to count not those which differ from zero by less than o"-O2 numerically, but those which differ from the mean value o"-oi by less than this amount : i.
