"In the year 1764, Dr. Long published the third book of his Astronomy as a part only of his second volume.  Before the time of his death he had finished and printed off the fourth, and a small part of the fifth book.  Mr. Dunthorn made ... a rough draft of the remaining part ...  After his death, Mr. Wales was prevailed upon to revise and correct Mr. Dunthorn's continuation, and to complete it upon the original plan." -- Advertisement, v.2.
