On p. 182, The ’Rudolphine’ Tables are misspelled two ways ([182.27], [182.29]). Both are corrected.

On pp. [327-329], the symbol for Uranus (♅) as printed is not quite the same as the symbol available to us. In the text, the small circle is on the top.

Other errors, deemed most likely to be the printer’s, have been corrected, and are noted here. The references are to the page and line in the original.
