18. AFFECTION OF THE BRAIN.
When the brain is affected, the patient suddenly complains of violent headache, vomits repeatedly, loses his eye-sight, has furious delirium, or coma (a state of sleep from which it is difficult to rouse the patient); his pupils dilate; the pulse becomes small, intermits; sometimes the skin becomes cold; there is dyspnœa (difficulty of breathing), fainting, paralysis, convulsions, and finally death; or, sometimes, the paroxysm passes suddenly by with bleeding from the nose or with a profuse perspiration.
19. AFFECTION OF THE CEREBELLUM AND SPINE.
In affections of the cerebellum and spinal marrow, the patient complains of violent pain in the back of the head and neck, in the spine, and frequently in the whole body. These also frequently terminate with the destruction of life.
20. During all these invasions of the nervous centres there is little or no rash, and what appears is of a pale, livid hue.
21. PUTRID SYMPTOMS.
Next to those most dangerous forms—most dangerous, because the organic power (the vis medicatrix naturæ), from which the restoration of health must be expected, and without which no physician can remove the slightest symptom of disease, becomes partly paralyzed from the beginning—putrid symptoms present a good deal of danger, although they give the organism and the physician more time to act.
