We keep our border-line cases separate in order to emphasize that pathological lying by an insane person does not make a pathological liar in the true sense. We should hesitate, however, to give in legal form a verdict of insanity in several of these border-line cases we cite--they are very difficult to classify, and the question of responsibility called for sometimes in court work is unanswerable. Keeping even these mild cases away from our others serves, however, to lessen confusion; we need in this subject to conserve all the clearness possible by holding to fundamental classifications and showing up vagueness of definition where it does exist. Perhaps we are over-particular in keeping such a case as No. 22 in this chapter. The commonsense observer would hardly regard this girl as at all lacking, even in self-control. On the other hand, for the purpose of illustrating the subject of pathological accusation we have kept Case 17 in the previous chapter when it clearly shows great resemblance to Case 26 and is in reality a border-line type. Then, too, the swindler, Case 12, in some respects belongs in this chapter. We are hardly called on in this work to discuss the lying of drug habitues, although they so frequently in their mental conditions represent border-line types. They are often on the verge of a psychosis as the result of their intoxications. Their lying is mostly done for a purpose, to be sure, and hence much would not come under the head of pathological lying, but occasionally veracity is so much interfered with that there seems to be a tendency to aimless lying. This class of cases, however, is sufficiently discussed in special literature pertaining to the subject.[24] [24] Vide, ``Morphinism and Narcomanias From Other Drugs,'' by T. D. Crothers.

CASE 22 Summary: A girl of 14, a most vigorous and vivacious personality, had for a couple of years pursued a curiously active career of misrepresentation, of obtaining goods under false pretenses and running away from home even to distant places. Her conversational ability was above normal; her lies were evolved for the purpose of adapting herself to the peculiar circumstances in which she frequently found herself. Her general conduct combined with her abnormal psychomotor activity gave ground for the diagnosis of constitutional excitement--hypomania.
