The same explanation of what are called putrid symptoms in fever, is very happily delivered by Mr. Hunter in the following words: "It is to be observed (says this acute physiologist) that when the attack upon these organs, which are principally connected with life, proves fatal, that the effects of the inflammation upon the constitution run through all the stages with more rapidity than when it happens in other parts; so that at its very beginning, it has the same effect upon the constitution which is only produced by the second stage of inflammation in other parts[8]." [8] Treatise on Inflammation. chap. I. 8. 3. The _synocha_, or the common inflammatory state of fever, attacks suddenly with chills, and is succeeded by a quick, frequent, and tense pulse, great heat, thirst, and pains in the bones, joints, breast, or sides. These symptoms sometimes occur in the plague, the jail and yellow fever, and the small-pox; but they are the more common characteristics of pleurisy, gout, and rheumatism. They now and then occur in the influenza, the measles, and the puerperile fever. 4. The _synochus_ state of fever is known by a full, quick, and round pulse without tension. The autumnal bilious fever and colic, also the gout, often appear in this form. 5. There is a state of fever in which the pulse is small, but tense and quick. The patient, in this state of fever, is seldom confined to his bed. We observe it sometimes in the chronic rheumatism, and in pulmonary consumption. The inflammatory state of this grade of fever is proved from the inefficacy of the volatile tincture of guaiacum and other stimulants to remove it, and from its yielding so suddenly to blood-letting. I have called it the _synochula_ state of fever. 6. There is a state of fever inclining more to the synocha, than what is called the typhus, or low chronic state of fever. I have called it the _synochoid_ state of fever. 7. The _typhus_ state of fever is generally preceded by all those circumstances which debilitate the system, both by the action and abstraction of stimuli. It is known by a weak and frequent pulse, a disposition to sleep, a torpor of the alimentary canal, tremors of the hands, a dry tongue, and, in some instances, by a diarrh[oe]a. These symptoms occur most frequently in what is called the jail, the ship, and the hospital fever. I heard of it in a few cases in the yellow fever of 1793, and all writers take notice of cases of the plague, which run on into a slow fever that continues 30 or 40 days. I have seen it succeed the common bilious fever, pleurisy, and influenza. It has been confounded with the malignant state of fever, or what is called the typhus gravior; but it differs widely from it in being accompanied by a feeble excitement in the blood-vessels, from a feeble stimulus, and by the usual signs of debility from abstraction in every other part of the body.
