I know not whether this is to be classed among the "unsatisfactory" derivations already submitted to your correspondent, but should be glad to hear his opinion on its soundness. E. A. D. _Sheridan and Vanbrugh_ (Vol. iv. p. 24.).--Had O. O. consulted the "Life of Sheridan" which precedes Bohn's Collection of the _Dramatic Works of Sheridan_ (which, having the volume in his hand, he ought to have done), he would have seen that it is expressly mentioned (p. 51.) that Sheridan, having become part proprietor of Drury Lane Theatre-- "His first commencement as a manager was not of that brilliant kind to give any promise of great improvement in the conduct of the theatre. _An alteration_ of Vanbrugh's play the _Relapse_ was the first production, under the name of a _Trip to Scarborough_. It was brought out on February 24, 1777. This was an unfortunate commencement: neither the public nor the actors were satisfied." Further, it is printed at the end of Sheridan's _Dramatic Works_, followed by _Pizarro_, printed in smaller type, so as to make them appear like an appendix; and hence it could hardly be expected that any one would think of attributing the _Trip to Scarborough_, altered from Vanbrugh's _Relapse_, to Sheridan, any more than it could be considered as intended to call him the author of _Pizarro_, because he altered Kotzebue's _Spaniards in Peru_, and adapted it to, and had it represented on, the stage. A HERMIT AT HAMPSTEAD. "_Felix quem faciunt aliena pericula cautum_" (Vol. iii., p. 482.).--This line of Plautus is followed by parallel quotations from other writers. To these I may add the French version: "Heureux celui qui pour devenir sage, Du mal d'autrui fait son apprentisage." J. R. "_Alterius Orbis Papa_" (Vol. iii., p. 497.; Vol. iv., p. 11.).--Fuller, in his _Worthies of England_, edit. London, 1662, "Staffordshire," p. 41., uses this expression, writing, of Cardinal Pole. It is as follows: "Yet afterwards he (Pole) became '_Alterius Orbis Papa_,' when made Archbishop of Canterbury by Queen Mary." J. N. B. West Bromwich, June 28. 1851. _Umbrella_ (Vol. iii., pp. 37. 60. 126. 482.).--In Fynes Moryson's _Itinerary_, "printed by John Beale, 1617, part iii. booke i. chap. ii. p. 21.," is the following passage: "In hot regions, to auoide the beames of the sunne, in some places (as in Italy) they carry Vmbrels, or things like a little canopy, over their heads; but a learned Physician told me, that the use of them was dangerous, because they gather the heate into a pyramidall point, and thence cast it down perpendicularly upon the head, except they know how to carry them for auoyding that danger." C. DE D. _To learn by Heart, "Apprendre par Coeur"_ (Vol. iii., pp. 425. 483.).--Quitard, a French writer on Proverbs, says,--
