The colonel dwelt in a vortex of specialists who were still specializing in trying to determine what was troubling him. They hurled lights in his eyes to see if he could see, rammed needles into nerves to hear if he could feel. There was a urologist for his urine, a lymphologist for his lymph, an endocrinologist for his endocrines, a psychologist for his psyche, a dermatologist for his derma; there was a pathologist for his pathos, a cystologist for his cysts, and a bald and pendantic cetologist from the zoology department at Harvard who had been shanghaied ruthlessly into the Medical Corps by a faulty anode in an I.B.M. machine and spent his sessions with the dying colonel trying to discuss Moby Dick with him.
