I did so, and truly it was as if I looked upon the page of a book printed in the largest and clearest type. I hesitate to say what I saw written there, since the glass was strong enough to reach not only the mind itself, but further into the very depths of my subself-consciousness. On the surface, man thinks well of himself; this continues in modified intensity to his self-consciousness, but the fool does not live who, in his subself-consciousness, the Holy of Holies of Realization, does not know that he is a fool. "Take 'em off," I cried, for they seemed to burn into the very depths of my soul. "That isn't necessary," said AEsculapius, kindly. "Just turn your eyes away from the glass a moment and they won't bother you. I want to cure this trouble of yours." I stopped looking at myself in the mirror and the tense condition of my nerves was immediately relieved. "Feel better right away, eh?" he asked. "Yes," I admitted. "So I thought," he said. "You've momentarily given up self-contemplation. Now lower your gaze. Look at your chest a moment." Just what were the properties of the glass I do not know, nor do I know how one's chest should look, but, as I looked down, I found that just as I could penetrate to the depths of my mind through my eyes, so was it possible for me to inspect myself physically. "Nothing the matter there, eh?" said AEsculapius. "Not that I can see," said I. "Nor I," said he. "Now, if you think there is anything the matter with you anywhere else," he added, "you are welcome to use the glasses as long as you see fit." I took a sneaking glance at my right side and was immediately made aware of the fact that all was well with me there, and that all my trouble had come from my ill-advised "wondering" whether that Midas omelet would bother me or not. "These glasses are wonderful," said I. "They are a great help," said AEsculapius. "And do you always permit your patients to put them on?" I asked. "Not always," said he. "Sometimes people really have something the matter with them. More often, of course, they haven't. It would never do to let a really sick man see his condition. If they are ill, I can see at once what is the matter by means of these spectacles, and can, of course, prescribe. If they are not, there is no surer means of effecting a cure than putting these on the patient's nose and letting him see for himself that he is all right." "They have all the quality of the X-ray light," I suggested, turning my gaze upon an iron safe in the corner of the room, which immediately disclosed its contents. "They are X-ray glasses," said AEsculapius. "In a good light you can see through anything with 'em on. I have lenses of the same kind in my window, and when you came up I looked at you through the window-pane and saw at once that there was nothing the matter with you." "I wish our earthly doctors had glasses like these," I ventured, taking them off, for truly I was beginning to fancy a strain.
