His best-known work is ''A New Analysis of Chronology'', which took twenty years to complete and was finally published in three volumes (1809 - 1812). In this book, which deals with the chronology of the whole Bible, Hales made it his rule as far as possible to use original sources. His other works include ''The Inspector, or, Select Literary Intelligence for the Vulgar'' and ''Irish Pursuits of Literature'' (both 1799), ''Methodism Inspected'' (1803–5), and ''Letters on the Tenets of the Romish Hierarchy'' (1813). From about 1820 or earlier he suffered from depression. He died in 1831.
