This passage is assigned to Plautus in the _Sylloge_ of Petrus Lagnerius, Francf. 1610, p. 312., but I cannot find it in this author. C. H. P. Brighton, May 12. 1851. Perhaps it is hardly an answer to EFFIGIES to tell him that the earliest occurrence of this line, with which I am acquainted, is in a rebus beneath the device of the Parisian printer, Felix Balligault, about the year 1496. Thus: "Felix quem faciunt aliena pericula cautum. Felici monumenta die felicia felix Pressit: et hæc vicii dant retinentve nihil." The device is a fruit-tree, from which a shield is suspended inscribed _felix_. Two apes are seated at the foot of the tree. The thought is, however, common to the wise and the witty of every age. Menander has it thus:-- "Βλέπων πεπαίδευμ᾽ εἰς τὰ τῶν ἄλλων κακά." And Plautus: "Feliciter sapit qui alieno periculum sapit." Compare Terence, _Heaut._ i. 2. 36.: "Periculum et aliis facere, tibi quod ex usu siet." And Diodorus Siculus, i. ab init.: "Καλὸν γὰρ τὸ δύνασθαι τοῖς τῶν ἄλλων ἀγνοήμασι πρὸς διόρθωσιν χρῆσθαι παραδείγμασι." And Tibullus, lib. iii. eleg. vi.: "Felix, quicunque dolore Alterius disces posse carere tuo." These indications may perhaps put your correspondent in the way of a more satisfactory answer to his question. S.W. SINGER. * * * * * _Church Bells_ (Vol. iii., p. 339.).--Should the following extract from Mr. Fletcher's _Notes on Nineveh_ have escaped the notice of MR. GATTY, it may probably interest him:-- "During the following (12th) century Dionysius Bar Salibi occupied the (Jacobite) patriarchal throne, a man noted for piety and learning. He composed several works on theological subjects, among which we find a curious disquisition on bells, the invention of which he ascribes to Noah. He mentions that several histories record a command given to that patriarch to strike on the bell with a piece of wood three times a day, in order to summon the workmen to their labour while he was building the ark. And this he seems to consider the origin of church bells, an opinion which, indeed, is common to other Oriental writers."--Vol. ii. p. 212. E. H. A.
