§ 40. The difference, in the detail of circumstances, between artful or false witnesses and those who testify the truth, is worthy of especial observation. The former are often copious and even profuse in their statements, as far as these may have been previously fabricated, and in relation to the principal matter; but beyond this, all will be reserved and meagre, from the fear of detection. Every lawyer knows how lightly the evidence of a _non-mi-recordo_ witness is esteemed. The testimony of false witnesses will not be uniform in its texture, but will be unequal, unnatural, and inconsistent. On the contrary, in the testimony of true witnesses there is a visible and striking naturalness of manner, and an unaffected readiness and copiousness in the detail of circumstances, as well in one part of the narrative as another, and evidently without the least regard either to the facility or difficulty of verification or detection.(65) It is easier, therefore, to make out the proof of any fact, if proof it may be called, by suborning one or more false witnesses, to testify directly to the matter in question, than to procure an equal number to testify falsely to such collateral and separate circumstances as will, without greater danger of detection, lead to the same false result. The increased number of witnesses to circumstances, and the increased number of the circumstances themselves, all tend to increase the probability of detection if the witnesses are false, because thereby the points are multiplied in which their statements may be compared with each other, as well as with the truth itself, and in the same proportion is increased the danger of variance and inconsistency.(66) Thus the force of circumstantial evidence is found to depend on the number of particulars involved in the narrative; the difficulty of fabricating them all, if false, and the great facility of detection; the nature of the circumstances to be compared, and from which the dates and other facts are to be collected; the intricacy of the comparison; the number of the intermediate steps in the process of deduction; and the circuity of the investigation. The more largely the narrative partakes of these characters, the further it will be found removed from all suspicion of contrivance or design, and the more profoundly the mind will repose on the conviction of its truth.
