Newman 1845:11 "The Irish life referred to by Archbishop Ussher does not appear entitled to much consideration" in St. Ninian's early days, for example; and elsewhere in the book.
Hardy 1862:44 "The Irish Life was written long after Ninian's death, by an author of little discretion, who wished to adjust the conduct of the Saint to the usages of his own time." in the footnote, for example.
