One of their newest instruments and the most effective for the avoidance of surgical operations was the alclirolan, a combination of microscope, camera in vacuo, and electric power. It could by means of a swiftly moving film, on which fell electric light through a vacuum, take a picture of the life-processes within the living body, however minute. Then by means of magnifiers and brilliant light they could throw from this film a moving picture on a screen, so enormously enlarging the process of any part of the body that even a novice could see at a glance what was healthy and what was diseased or obstructed. It was this alclirolan that made the study of physiology in the living body simple enough for the very youngest. It was by this that they were able to supplement the experimental hall at the entrance to Oomalefa, and to show in process the effect in actual human bodies of disease, microbes, and remedies. Every minute process of the various organs and tissues of the body and of the brain was reproduced marvellously magnified on the walls. There was no new medicine but was tested and had its effects on the various parts of the body revealed by this new method. There was no new disease or microbe but gave up its secrets to this instrument. The only surgery they had was creative, like all their other sciences and arts. It had to do chiefly with the capacity of the skull. The appearance of epilepsy in some of their ablest men and families ages before had pointed the way. Their knowledge of the localities and tissues of the brain, along with the semi-transparency of their skulls and the advantages their alclirolan had introduced, gave them complete command of everything that was proceeding within the head. They could by their electric apparatus light up the tissues and see what part was growing and pressing upon the containing bone. They therefore learned to trephine the epileptic sufferers and thus relieve the oppressed locality of the brain. From this practice and the growing knowledge of the great purpose of life they passed into the stage of creative surgery. For imperfect tissue perfect was substituted. Man-grafting had become the most important branch of surgery. They could modify and even create new faculty or organ or tissue by grafting what they had made on to the part of the infantile system which needed it. A child to be devoted to a special pursuit which needed some faculty exceptionally developed had his skull enlarged in its early and plastic stage over the portion of the brain that was the material equivalent and instrument of the faculty; and when most of the energies of life began to pour into his pursuit the tissue had room to grow. If a combination of exceptional faculties were needed in any profession or pursuit, protuberances in various parts under the hair or even on the brow could be perceived on looking closely. So nice had this creative art become that the most delicate and minute trephining
