These affections, I had read, are sometimes transitory and sometimes obstinate. I had read of cases in which the appearance, at first harmless, had, step by step, degenerated into something direful and insupportable, and ended by wearing its victim out. Still as I stood there, but for my bestial companion, quite alone, I tried to comfort myself by repeating again and again the assurance, 'the thing is purely disease, a well-known physical affection, as distinctly as small-pox or neuralgia. Doctors are all agreed on that, philosophy demonstrates it. I must not be a fool.
