Premising all this, we may suppose that a peculiar psychic concordance, which failing a better term might be called mediumistic, exists between Lola and her mistress. The mistress then in some way will have "communicated" through the dog the substance of her psychic self (perhaps with eventual autonomous additions from the canine or other psychic entity); all this happening, we must suppose, in a subliminal way, with partial psychical disassociation on the part of the authoress, if not also probably on the part of Lola, about which I am quite certain (and in this I agree with Neumann) that it absolutely does not understand anything or know anything of almost all the manifestations of thought which it exhibits. There remain the questions (if the possibility of such duplicate mediumistic phenomena is admitted _a priori_ to be possible) as to the point at which the normal relationship between a human person and an animal passes over into this supernormal one; and, finally, as to what particular known facts in the case of Lola, besides the rather too general analogies already mentioned, speak in favour of this hypothesis. Into the mediumistic endowment of the investigator it seems to me useless to inquire since _a priori_ many persons, so it seems, are more or less strikingly endowed, and the conditions which determine results are not sufficiently known. At the most there exist some indications--e.g. in Morselli's masterly work (2)--of the existence of some concordances between the phenomenology of mediumism and hysterical, hysteroid, or at least "sensitive" temperaments. And I believe that--with the help of their own publications, properly analysed--it would not be too difficult to attribute one or the other of such physio-psychic varieties to those persons who have up to the present obtained the best results with "thinking animals." More interesting appears to me the investigation of the question whether animals themselves have already given any clear proof of being able to be "sensitive" in the mediumistic sense. And I must say that such a proof seems to have almost been reached. I may refer on this subject to the exhaustive monograph published in 1905 by Bozzano (1) and written with the special competency and clearness that distinguish the well-known Genoese psychist.
