_The Twentieth of the Thirty-nine Articles._--In a note to a work entitled _Sketches of the History of Man_, Dublin, 1779, at vol. i. p. 104. I observe the following statement: "In the Act 13th of Elizabeth, anno 1571, confirming the Thirty-nine Articles of the Church of England, these Articles are not engrossed, but referred to as comprised in a printed book, intitled 'Articles agreed to by the whole Clergy in Convocation holden at London, 1562.' The forged clause is, 'The Church has power to decree Rites and Ceremonies, and authority in Controversies of Faith.' That clause is not in the Articles referred to; nor the slightest hint of any authority with respect to matters of faith. In the same year, 1571, the Articles were printed both in Latin and English, precisely as in the year 1562. But soon after came out spurious editions, in which the said clause was foisted into the Twentieth Article, and continues so to this day," &c. This is a grave charge. Is it a true one? I have not at hand the authorities by which to examine it, and therefore seek an answer from some of your readers who may be able to give it. My question refers to the imputation of a clause having been foisted into our Articles of Faith by a forgery, and still continuing in them; not to the truth of any part of our Articles as they now stand. To this there is sufficient testimony. CM. London, July 25. 1851. [The following note from p. 131. of Mr. Hardwick's recently published _History of the Articles_ will furnish a reply to this Query:-- "He (Laud) was accused of forging the contested clause in Art. XX. And after appealing to four printed copies of the Articles, one of them as early as 1563, and all containing the passage which the Puritans disliked, he added, 'I shall make it yet plainer: for it is not fit concerning an Article of Religion, and an Article of such consequence for the order, truth, and peace of the Church, you should rely upon my copies, be they never so many or never so ancient. Therefore I sent _to the public records in my office, and here under my officer's hand, who is public notary, is returned to me the Twentieth Article with this affirmative clause in it, and there is also the whole body of the Articles to be seen.'_--_Remains_, ii. 83. (quoted by Bennet, 166.) The copy thus taken before the destruction of the records is said to be still extant; Bennet made use of it, and has printed it in his _Essay_, 167-169."] _Exons of the Guard._--Can any of your readers inform me what are the duties of these officers, and the derivation of their title? I find, in the papers describing her Majesty's state ball, the following: "the exons or capitaines exempts _de la garde du corps;_" but that does not throw much light upon the subject. E. N. W.
