With their clirolans and vimolans and other aids to the senses the medical sages could detect the slightest jar in the rhythm of the system and locate it with the greatest ease. Having located it, they knew the parasite that had begun to multiply and clog the organ or tissue or function, and the treatment that it required. Every moral fault had its corresponding disease and infinitesimal parasite they held; and so rapidly could the minute organisms increase and so impalpably and easily could they migrate from human being to human being that the contagion of vice was a thousand times more appalling in its ravages than that of mere physical disease. There was great trepidation when any ailment attacked the body of a Limanoran, and he was heartily ashamed of its appearance and alarmed lest it should spread, or lead to its natural consequence, moral degeneracy; but, if the parasitic attack was found to be on one of the higher centres of life, the alarm was great and wide, for it was far more subtle in its insidiousness and omnipotence. The patient was at once quarantined and only the noblest of medical sages could break his isolation. All the powers of his mind and of the minds of his nurses and medical attendants were concentrated on the offending tissue, and strong thermoelectric aids were applied to it, so that it should soon regain its old vitality and drive the intruders out. In the chamber was kept up an atmosphere of the special elements which would nourish the degenerate cells and also of those that would destroy the microbes; only as a last resort was surgery used and the part laid open to the local application of re-agents against the hostile organisms. The ruder and older forms of evil--passion, envy, malice, hatred, jealousy, contempt, vanity--rarely appeared in grown men and women at that advanced stage of their civilisation. They had become diseases of the immature periods of life, when the soul was passing through the primitive phases of the development of mankind. They were the ailments of childhood and youth; and hundreds of the Limanorans now grew up without once experiencing any one of them. When they did appear, isolation was the first step; and the parents or proparents could generally cope with the moral disease without having recourse to a medical family or to Oomalefa. Every traditional method of cure was applied most vigorously, for they shrank from the thought of leaving any seed of the contagion in the system to germinate at some later and more dangerous period of life.
