The "oat" appears to me so little the companion of luxury and pleasure, that I am wholly at a loss to account for the origin of this phrase, which is in the mouth of every one. BEAU NASH. Bath. _The Dr. Richard Mortons._--I shall feel greatly indebted to any reader of "N. & Q." who can give me some account of Dr. Richard Morton, a celebrated physician of Greenwich, _temp._ William and Mary, and of his son Dr. Richard Morton, who died in 1730. Were they descended from the Mortons of Severn Stoke, co. Worcester? and what was the precise degree of their relationship with the Mortons of Slaugham, co. Sussex? MARK ANTONY LOWER. _General Lambert_ (Vol. iv., p. 339.).--A correspondent shows the probability or certainty that the hitherto received opinion as to the long confinement and death in Guernsey of this old parliamentary general is not correct. But Mr. Hallam and others who report this, report also that he was tried with Sir Harry Vane; and that his "submissive behaviour" was such a contrast to that of his noble fellow-prisoner that it perhaps influenced his sentence. Where is the proof of his behaviour to be found? Vane's trial has been published separately. It is also in the _State Trials_, with the trials of the regicides; but neither there nor elsewhere can I find the trial of Lambert. G. L. _Cross-legged Effigies and Collars of SS._--As some of your correspondents are sending to "N. & Q." accounts of sepulchral effigies bearing SS. collars, I should be obliged to them if they would mention when such effigies are cross-legged. Does any effigy in this attitude exist _bearing a date_ as late as 1350? W. H. K. _The Crooked Billet._--Can any of your readers inform me whether there be any legend connected with the "Crooked Billet," which is frequently used in this neighbourhood as a sign to a village inn? The sign itself is formed of a crooked piece of wood, or two or three pieces joined, and suspended over the door of the public-house. T. D. Gainsbro'. _Collins the Poet, and his Ode on the Music of the Grecian Theatre._--In Seward's _Anecdotes of distinguished Persons_ there is a letter from Collins to Dr. Hayes, professor of music, Oxford, in which, after alluding to his "Ode on the Passions," he mentions another Ode, which appears to have been actually written. "The subject," he states, "is _the Music of the Grecian Theatre_, in which," he goes on to say, "I have, I hope naturally, introduced the various characters with which the chorus was concerned, as Oedipus, Medea, Electra, Orestes, &c. &c. The composition too is probably more correct, as I have chosen the ancient tragedies for my models, and only copied the most affecting passages in them." The letter is dated "Chichester, November 8, 1750." Collins died in 1756. The Ode is lost; but assuredly every effort should be made to bring it to light. SMINTHEUS.
