If we turn our glance away from the sensational phenomena of literature to the phenomena of ordinary life, which are not uncommonly enacted in the halls of justice, it is in first rank the incorrigible swindlers and sharpers that excite our attention. We have received on this subject from Dr. ANTON DELBRUECK, a physician of a Swiss insane asylum, an interesting little work bearing the title _Die pathologische Lüge und die psychisch abnormen Schwindler_, Stuttgart, 1891, Verlag von Ferdinand Enke. In this book the author makes an investigation of the gradual transition of a normal psychological process into processes exhibiting pathological symptoms, and shows, in so doing, by ample material, that in every kind of intentional deception the consciousness of intention can exhibit very different degrees of intensity and can imperceptibly sink in a succession of cases to zero. As a matter of course, Delbrück’s treatise is primarily of interest to medical experts and lawyers, but it will also be of interest in a secondary degree to all circles that devote their attention to psychological studies generally, particularly so to educators who have not infrequently to do with pathological lies, as G. Stanley Hall quite recently pointed out in a very instructive article in _The America Journal of Psychology_ on the lying of children, and as is developed in the work of Dr. Sollier, before mentioned in _The Monist_, entitled _La psychologie de l’idiot et l’imbécile_, which is also to be had in a very good German edition, translated by Paul Brie, under the title _Der Idiot und der Imbecille_, published by Leopold Voss of Hamburg.
