25. The hæmorrhagic state of fever, in which are included discharges of blood from the nose, lungs, stomach, liver, bowels, kidneys and bladder, hæmorrhoidal vessels, uterus, and skin. Hæmorrhages have been divided into active and passive. It would be more proper to divide them, like other states of general fever, into hæmorrhages of strong and feeble morbid action. There is seldom an issue of blood from a vessel in which there does not exist preternatural or accumulated excitement. We observe this hæmorrhagic state of fever most frequently in malignant fevers, in pulmonary consumption, in pregnancy, and in that period of life in which the menses cease to be regular.
26. The amenorrhagic state of fever occurs more frequently than is suspected by physicians. A full and quick pulse, head-ach, thirst, and preternatural heat often accompany a chronic obstruction of the menses. The inefficacy, and even hurtful effects, of what are called emenagogue medicines, in this state of the system, without previous depletion, show the propriety of introducing it among the different states of fever.
I have designedly omitted to take notice of other states of general fever accompanied with local disease, because they are most frequently combined with some one or more of those which have been mentioned. They may all be seen in Dr. Cullen's Synopsis, with their supposed respective generic characters, under the class of pyrexiæ, and the order of fevers. We come now in the
III. And last place, to mention the misplaced states of fever. The term is not a new one in medicine. The gout is said to be misplaced, when it passes from the feet to the viscera. The periodical pains in the head, eyes, ears, jaws, hips, and back, which occur in the sickly autumnal months, and which impart no fulness, force, nor frequency to the pulse, are all misplaced fevers. There are, besides these, many other local morbid affections, which are less suspected of belonging to febrile diseases. The nature of these states of fever may easily be understood, by recollecting one of the laws of sensation, that is, that certain impressions, which excite neither sensation nor motion in the part of the body to which they are applied, excite both in another part. Thus worms, which are not felt in the stomach or bowels, often produce a troublesome sensation in the throat, and a stone, which is attended with no pain in the bladder, produces a troublesome itching in the glans penis. In like manner, the irritants which produce fever in ordinary cases pass through the blood-vessels, and convey their usual morbid effects into a remote part of the body which has been prepared to receive them by previous debility. That this is the case, I infer further, from fevers being called back from their misplaced or suffocated situations, by creating an artificial debility in the arteries by the abstraction of blood. This is often done in muscular convulsions, and in several diseases of the brain.
Under this class of fevers are included
27. The chronic hepatic state of fever. The causes, symptoms, and remedies of the liver disease of the East-Indies, as mentioned by Dr. Girdlestone, all prove that it is nothing but a bilious fever translated from the blood-vessels, and absorbed, or suffocated, as it were, in the liver. This view of the chronic hepatitis is important, inasmuch as it leads to the liberal use of all the remedies which cure bilious fever. Gall stones and contusions now and then produce a hepatitis, but under no other circumstances do I believe it ever exists, but as a symptom of general or latent fever.
28. The hæmorrhoids are frequently a local disease, but they are sometimes accompanied with pain, giddiness, chills, and an active pulse. When these symptoms occur, it should be considered as a hæmorrhoidal state of fever.
29. The opthalmia, when it occurs, as it frequently does in sickly seasons, with a quick and tense pulse, and pains diffused over the whole head, may properly be called an opthalmic state of fever.
30. The tooth-ach, and
31. Ear-ach, when they arise from colds, and are attended with great heat, a quick and tense pulse, and pains in the head, are odontalgic and otalgic states of fever.
