M. Lombroso soon after published his experiences and reflections, in an article in the _Annales des sciences psychiques_ (1892) which ends thus: None of these facts, (which we must admit, because no one can deny things which he has seen) is of such a nature as to lead us to form for their explanation an hypothesis of a world different from that admitted by the neuro-pathologists. Above all, we must not forget that Mme. Eusapia is a neuropath; that in her childhood she received a blow on the left parietal bone, which produced a hole so deep that you could put your finger in it; that she remained subject to attacks of epilepsy, catalepsy, and hysteria, which take place especially during the seance phenomena; and that, finally, she has a remarkable obtuseness of touch. Well, I do not see anything inadmissible in this,--that in the case of hypnotic and hysterical persons the excitation of certain centres, which become powerful by the paralysis of all the others and then provoke a transposition and a transmission of physical forces, may also produce a transformation in luminous force or in motive force. Thus we understand how the force in a medium which I shall call cortical or cerebral may, for example, lift the table, pull somebody's beard, hit him, caress him, etc. During the transposition of senses due to hypnotism,--when, for example, the nose and the chin _see_ (and that is a fact which I observed with my own eyes), and when for some moments all the other senses are paralyzed, the cortical centre of vision, which has its seat in the brain, acquires such an energy that it supersedes the eye. It is this which we have been able to prove, Ottolenghi and I, in the case of three hypnotized persons, by making use of the lens and of the prism. The phenomena observed would be explained, according to this theory, by a _transformation_ of the powers of the medium. Let us continue our account of the experiments. Taking into consideration the testimony of Professor Lombroso, several savants--including MM. Schiaparelli, director of the observatory at Milan; Gerosa, professor of physics; Ermacora, doctor of natural philosophy; Aksakof, councillor of state to the Emperor of Russia; Charles du Prel, doctor of philosophy in Munich; Dr. Richet, of Paris, and Professor Buffern--met in October, 1892, in the apartment of M. Finzi, at Milan, to renew these experiments. M. Lombroso was present at several of the soirees. There were seventeen in all. The experimenters present signed the following long declaration:
