"His first machine produced the vibrations of invisibility in a field with a three-foot radius in all directions. That is, it caused every solid object, within this atmospheric field, to vibrate at the rate, tone, or speed of invisibility. This machine was in no sense rotary. It departed from the original example of a revolving wheel and entered instead into general vibration in a given or measured field. "The pulsations or vibrations of an ordinary automobile engine will cause every ounce of metal, or solid, in the automobile--including the driver--to vibrate at the same rate or momentum. This is a known fact, and it provided the basis for Darrow's experiments. * * * * * "Darrow built two machines. The first had a field with a radius of three feet on all sides. This was used by the killer in his murders. Jouret stole this machine first, thus paving his way for the second robbery. "With the first machine in his possession, Jouret was able to commit the Darrow murder without being seen. He had to have the second and larger machine, however, to make his auto disappear. He stole the larger machine at the time of the Darrow murder, and with it he had his auto vanish, as the gardener testified. "Both machines were hopelessly smashed in the wreck, but with Darrow's documents at hand, we might be able to construct another and a larger model. A machine built on the proper scale will make a plane or a battleship invisible and should, as Darrow said, make war against this country impossible. * * * * * "Digging into Jouret's history we found that the 'Misses Jouret' were one-cell triplets. Their mother, Mrs. Doris Nettleton, an English woman, was a member of Jouret's troupe, as was the father. "The mother died at the birth of the triplets. The father died a few years later. The company was touring Australia at the time. Jouret and the father had the birth of only one baby recorded. She was named Doris, after the mother. The other girls also used this one name. They now have only one name among them until the court gives them individual names. "Jouret never let but one girl be seen at a time. The reason was that he and the father had planned to use the girls, when grown, to create a surprising stage illusion. In this illusion, one girl was to act as the earthly body and the other girls as the astral bodies of the same purported individual. "The father died, and Jouret retired before he ever got around to staging the illusion. Jouret continued the deception, however, because it appealed to his showman's nature. "The girls, at all times, were under the hypnotic control of Jouret, and, of course, knew nothing of his crazed intellect or crimes. Upon his arrest Jouret released the girls from the spell of years. "The Misses Nettleton say that Jouret was always kind to them and was an ethical showman until his mind gave way.
