From these different experiments with Eusapia Paladino, including those described in the first and second chapters, the impression is left that the phenomena observed are, to a great extent, real and undeniable; that a certain number may be produced by fraud; but that, in fact, the subject is very complex. Again, certain movements simply belong to the material order, while others belong at once to the physical order and the psychical order. All this study is vastly more complicated than people in general have any idea of. I am going to pass summarily in review other experiments made by the same medium, and shall afterwards devote a special chapter to the examination of frauds and mystifications. Let us look, first, at other achievements of Eusapia, and select from them whatever they also have to impart in the way of instruction or caution. CHAPTER IV OTHER SEANCES WITH EUSAPIA PALADINO The medium, whose marvellous seance performances we have been describing has been the subject of a long series of observations by eminent and careful experimenters. Her endowments are indeed exceptional. When you study with Eusapia, the comparison of her powers with those of ordinary cases makes you think of the difference between a fine electrical machine operated under good atmospheric conditions and a bad one operated on a rainy day. You see more with her in one hour than in a host of faulty trials with other mediums. Our study of these unknown forces will progress rapidly if, in place of limiting the results obtained to one or two groups, such as those which precede, we examine the totality of the observations made in the seances of this medium. My readers can then compare them with the preceding ones; they can judge, they can make their own estimates. The documents which I am now going to print are all borrowed from the _Annales des sciences psychiques_ and from the valuable collection of M. Albert de Rochas upon _The Externalization of Motivity_. A few words, first, about the debuts of Eusapia in her mediumistic career. Professor Chiaia, of Naples, to whom I owe it that I was able to receive Eusapia at my house and obtain the experiments reported above, was the first to bring her gifts into public notice. He first published on the 9th of August, 1888, in a journal issued at Rome, the following letter addressed to Professor Lombroso: _Dear Sir_,--In your article, _The Influence of Civilization upon Genius_ (which has incontestable beauties of style and of logic), I noticed a very happy paragraph. It seems to me to sum up the scientific movement (starting from the time when man first invented that head-breaking thing called an alphabet) down to our own day. This paragraph reads as follows:
