§ 70. Typhus.
As in synochal and erethic fevers the vascular system is principally excited, so is typhus characterized by great erethism of the nervous system, especially the ganglia and brain. Typhus is characterized by great variability of all the symptoms, an apparent contradiction between the symptoms themselves, and between the symptoms and the disease, for instance: dryness in the mouth and no thirst; no pain even when causes are at work which tend to produce pain; violent illness and no great feeling of illness, the patient asserting on the contrary that he feels well. The moral symptoms are of the utmost importance in typhus, as the selection of a remedy frequently depends upon them exclusively. It would be a fruitless attempt to give an accurate and never-changing description of typhus, which is an assemblage of the most varied phenomena. In the following chapter we give a general description of the characteristic symptoms of typhus, and shall furnish the particular indications for the remedies which are used in typhus, when we come to speak of the varieties of that disease. Recently it has been ascertained that the mucous membranes and the lymphatic glands, especially those of the ileum, are the principal seat of the disease, whence it has been termed typhus abdominalis; formerly the dynamic character of the disease, the depression of the nervous system was principally considered and, in accordance with that character, the disease was named febris nervosa which could now be properly applied only to typhus cerebralis. The more precise appellation of this fever has led homoeopathic physicians to the discovery of many valuable remedies for typhus, which it might have been difficult to discover without the pathological seat of the disease having been first ascertained by post-mortem examination.
