_"Hurrah!"_ (Vol. viii., pp. 20, 277, 323.).--It would almost deem that we are never to hear the last of "Hurrah! and other war-cries." Your correspondents T. F. and SIR J. EMERSON TENNENT appear to me to have made the nearest approach to a satisfactory solution of the difficulty; a step farther and the goal is won--the object of inquiry is found. I suppose it will be admitted that the language which supplies the _meaning_ of a word has the fairest claim to be considered its _parent_ language. What, then, is the meaning of "Hurrah," and in whet language? As a reply to this Query, allow me to quote a writer in _Blackwood's Magazine_, April 1843, p. 477. "'Hurrah!' means _strike_ in the Tartar language."--Note to art. "Amulet Bek." So then, according to this respectable authority, the end of our shouts and war-cries is, that we have "caught a Tartar!" Again, in _Blackwood_, 1849, vol. i. p.673., we read: "He opened a window and cried 'Hourra!' At the signal, a hundred soldiers crowded into the house. Mastering his fury, the Czar ordered the young officer to be taken to prison."--Art. "Romance of Russian History." Thus, in describing the "awful pause" on the night preceding the Russian attack on Ismail, then in possession of the Turks, Lord Byron says: "A moment--and all will be life again! The march! the charge! the shouts of either faith! Hurra! and Allah! and--one instant more-- The death-cry drowning in the battle's roar." _Works_, p. 684. col. 2. J. W. THOMAS. Dewsbury. _"Qui facit per alium facit per se"_ (Vol. viii., p. 231.).--"Qui facit per alium, est perinde ac si faciat per seipsum," is one of the maxims of Boniface VIII. (_Sexti Decret._, lib. v. tit. 12., de Reg. Jur. c. 72.; _Boehm. Corp. Jur. can._, tom. ii. col. 1040.), derived, according to the glossary (vid. in _Decret._, ed. fol., Par. 1612), from the maxim of Paulus (_Digest_, lib. 1. tit. 17., de Div. Reg. Jur. 1. 180.), "Quod jussu alterius solvitur, pro eo est quasi ipsi solutum esset." E. M. _Tsar_ (Vol. viii., pp. 150, 226.).--Is not _tsar_ rather cognate with the Heb. (¤Sar¤), a leader, commander, or prince? This root is to be found in many other languages, as Arabic, Persian; Latin _serro_. Gesenius gives the meaning of the word (¤Sarah¤), to place in a row, to set in order; to be leader, commander, prince. If _tsar_ have this origin, it will be synonymous with _imperator_, emperor. B.
