(2) It frequently happens, particularly in copying the old _scriptio continua_, that the eye of the scribe jumps from one word or group of letters to another the same or similar to it, either before or after it. In the former case the intervening words will be repeated, in the latter they will be omitted. Scholars designate these errors as =dittography= and =elision= respectively; printers know them under the name of a marriage and a funeral. The former mistake is not so serious, because it is at once detected on reading over the copy. A peep into any manuscript will show how frequently this error occurs, the repeated words being enclosed in brackets or surmounted with dots.[250] In Codex B such passages give us an opportunity of observing the beauty of the original writing, because the painstaking man who retraced the old writing with fresh ink in the eighth, or tenth, or eleventh century, or whenever it was, adding at the same time accents and punctuation marks, left these untouched. This kind of mistake very often happens in passages where a group of characters catches the eye for any reason, such as the occurrence of the abbreviation mark, Θ̅Σ̅, Ι̅Λ̅Η̅Μ̅, Α̅Ν̅Ο̅Σ̅, etc., and at the transition to a new page or leaf. The omission of a piece of the text of various length by homoioteleuton is as common, and is more serious.[251] Any critical apparatus will show the frequency of its occurrence. We often find there the note “a voce alterutra ... ad alterutram desunt” or “a voce 1^o ad vocem 2^o (3^o) transilit,” or “vox ... alterutra et intermedia desunt.” Compare, _e.g._, Codex D, Matt. xviii. 18 from γῆς to γῆς; x. 23; xxiii. 14-16. The result is worst when the mistake is not discovered till afterwards and the two fragments are patched together in some way with more or less success. Lacunæ that have not been doctored are very helpful in determining the relationship between different texts.[252] [Sidenote: Confusion.] (3) As errors of the tongue and the memory[253] rather than of the eye may be reckoned the =Transposition= and =Confusion= of particular combinations of letters or entire words. The former occurs so frequently in connection with a liquid, that in some cases it ceases to be a mistake. Thus we have on the one hand the confusion of κορκοδειλος with κροκοδειλος, Καρχηδων with Carthago, and on the other, εβαλον with ελαβον, βηθαραβα with βηθαβαρα, John i. 28; κιρνατω with κρινετω, ποντον with τοπον, בכרין, _talent_, Matt. xxv. 14-30, with כרכין, _cities_, Luke xix. 17, 19. Akin to this is the confusion of vowels with a similar sound, to which are to be ascribed all cases of =itacism=, as it is called—ἔγειρε and ἔγειραι, —εσθε and —εσθαι, ἑταίροις and ἑτέροις, χρηστὸς ὁ κύριος and χριστὸς ὁ κύριος, 2 Cor. xii. 1; φορέσωμεν and φορέσομεν, ἔχωμεν and ἔχομεν, Rom. v. 1; μετὰ διωγμῶν and μετὰ διωγμόν. Manifestly mistakes of this sort would occur more readily in dictation than in copying.
