It is requisite, says Mr. John Pitt Taylor (p. 500) speaking of "hearsay evidence" that whatever facts a witness speaks, he should be confined to those lying within his own knowledge. For every witness should give his testimony on oath, and should be subject to cross examination. But testimony from the relation of third persons cannot be subject to these tests. This rule of exclusion has been recognised as a fundamental principle of the law of evidence ever since the time of Charles II. To this he adds a note, with all due gravity: "The rule excluding heresay evidence, or rather the mode in which that rule is frequently misunderstood in Courts of Justice, is amusingly caricatured by Mr. Dickens _in his report_ of the case of Bardell _v._ Pickwick, p. 367." Bardell _v._ Pickwick! He thus puts it with the many thousand or tens of thousand cases quoted, and he has even found a place for it in his index of places. He then goes on to quote the passage, just as he would quote from Barnwall and Adolphus. How sagacious--full of legal point--is Boz's comment on Winkle's incoherent evidence. Phunky asked him whether he had any reason to suppose that Pickwick was about to be married. "'Oh no; certainly not,' replied Mr. Winkle with so much eagerness, that Mr. Phunky ought to have got him out of the box with all possible dispatch. Lawyers hold out that there are two kinds of particularly bad witnesses: a reluctant witness, and a too willing witness;" and most true it is. Both commit themselves in each case, but in different ways. The matter of the former, and the manner of the latter do the mischief. The ideal witness affects indifference, and is as impartial as the record of a phonograph. It is wonderful where Boz learned all this. No doubt from his friend Talfourd, K.C., who carefully revised "The Trial." Skimpin's interpretation of Mr. Pickwick's consolatory phrase, which he evidently devised on the spur of the moment, shows him to be a very ready, smart fellow. 'Now, Mr. Winkle, I have only one more question to ask you, and I beg you to bear in mind his Lordship's caution. Will you undertake to swear that Pickwick, the Defendant, did not say on the occasion in question--"My dear Mrs. Bardell, you're a good creature; compose yourself to this situation, for to this situation you must come," or words to that effect?' 'I--I didn't understand him so, certainly,' said Mr. Winkle, astounded at this ingenious dove-tailing of the few words he had heard. 'I was on the staircase, and couldn't hear distinctly; the impression on my mind is--'
