"The translator gives the following verses, which are now well known. I suspect he is the author of them, having never seen them at an earlier date. Mr. Halliwell, who is more likely than myself to have found them if they existed very early, names no version of them earlier than 1635:-- "'Thirtie daies hath September, Aprill, June and November, Febuarie eight and twentie alone, all the rest thirtie and one.'" Now it seems to me noteworthy to be recorded in your pages, that these lines, so familiar to us all from childhood, appear in a more complete shape in Harrison's _Description of Britaine_ prefixed to the first edition of Holinshed's _Chronicles of England, &c._, 1577, where at p. 119. the writer says: "Agayne touching the number of dayes in every moneth: "'_Junius, Aprilis, Septemq; Novemq; tricenos Un[=u] plus reliqui, Februy tenet octo vicenos, At si bissextus fuerit superadditur unus._' "'Thirty dayes hath November, Aprill, June and September, Twentie and eyght hath February alone, And all the rest thirty and one, But in the leape you must adde one.'" A. GRAYAN. FOLK LORE. _The Frog._--In the north of Lincolnshire the sore mouth with which babies are often troubled is called _the frog_. And it is a common practice with mothers to hold a real live frog by one of its hind legs, and allow it to sprawl about within the mouth of a child so afflicted. Is the same remarkable custom known elsewhere? The disease is properly called _the thrush_, and bears some resemblance to the disorder of the same name which affects _the frog_ of the horse's foot. I wish someone would unravel this entanglement. W. S. North Lincolnshire. _An Oath in Court_ (Vol. iv., pp. 151. 214).--Some time since, a woman refused to be sworn because she was in the family way. In _The Times_ of the 5th March, a woman at Chelmsford is represented as having said: "I swear this positively on the condition I am in, being about to become a mother?" Can anybody explain these facts? A. C. _St. Clement's and St. Thomas's Day._--I wish to inquire what is supposed to be the origin of begging apples, &c., on St. Clement's Day, and money (formerly wheat) on St. Thomas's? There is hardly any trace left of the former saint's day in this neighbourhood (Worcestershire, on the border of Staffordshire), but I have had convincing proof _to-day_ that St. Thomas is not forgotten, for we have had plenty of visitors, _tomorrow_ being Sunday. T. GOLDSEER. Dec. 20. 1851. Queries. SPEAKER LENTHALL. In a biographical notice (MS.) of Speaker Lenthall by the Rev. Mark Noble, I find the following passage: "His (Lenthall's) ancestor is mentioned in the will of Sir Richard Williams _alias_ Cromwell. Sir Richard was the great-grandfather of Oliver Lord Protector. There was always a friendship between the family of Cromwell and that of Lenthall."
