"For the bribery and perjury so painfully frequent in Attic testimony, the editor contents himself with quoting from an article in the _Quarterly Review_ (vol. xxxiii. p. 344.), in which the Greek courts of justice are treated of.--'We have all heard of a race of men who used, in former days, to ply about our own courts of law, and who, from their manner of making known their occupation, were recognized by the name of _Straw-shoes_. An advocate, or lawyer, who wanted a _convenient_ witness, knew by these signs where to find one, and the colloquy between the parties was brief. 'Don't you remember?' said the advocate--(the party looked at the fee and gave no sign; but the fee increased, and the powers of memory increased with it). 'To be sure I do.' 'Then come into the court and swear it.' And Straw-shoes went into the court and swore it. Athens abounded in Straw-shoes." See Mitchell's _Wasps_ of Aristophanes, note on line 945. C. FORBES. Temple. _Doctor Young_ (Vol. vii., p. 14.).--J. H. will find an account of Mrs. Hallows, the lady meant as Young's housekeeper, in Boswell's _Johnson_, p. 351., ed. 1848; and I can add to Anderson's note, that in the Duchess of Portland's correspondence with Young, of which I have seen the originals, Mrs. Hallows is always mentioned by her Grace with civility and kindness. C. _Scarfs worn by Clergymen_ (Vol. vii., p. 108.).--Your correspondent will find the subject of his Query fully discussed in the _Quarterly Review_ for June, 1851 (vol. lxxxix. p. 222.), the result being that the use of the scarf, except by chaplains of peers, dignitaries, &c., is a wholly unauthorised usurpation of very recent date. C. _Cibber's Lives of the Poets_ (Vol. v., p. 161.; Vol. vii., p. 113.).--MR. W. L. NICHOLS has transmitted to "N. & Q." what he calls a "curious letter which appears to have escaped the notice of MR. CROKER, though it corroborates his statement," relative to Dr. Johnson's mistake as to the authorship of those _Lives_. MR. NICHOLS is informed that he will find this "curious letter" _in extenso_ in Mr. Croker's last edition of _Boswell_, p. 504., with the date of 1846; the letter itself having been published in 1843. It is again referred to in p. 818. as decisive of the question. C. "_Letters on Prejudice_" (Vol. vii., p. 40.).--I have always understood from private and family sources, that _Letters on Prejudice_, inquired after by W. W. T., were written by a Miss Mary Kenny, an Irishwoman of great worth and ability. If I am right in this assertion, her brother, who was some time a fellow of the Irish University, and, if not lately dead, rector of one of the London churches, should be able to confirm it. A. B. R.
