AGUE, in Medicine, a periodical difeafe of the fever- 

 kind, confining of a cold fliivcring fit, preceded by a hot 

 one, and going off in a diaphorefis or fweating. If the 

 coldncfs and fliivering be inconfiderable, and only the hot fit 

 felt, the difeafe is called an intermittiug fever. According 

 to the periods or times of the returns of the fit, the difeak 

 is either a quotidian, tertian, or quartan ague, or 

 fever. The catife of ^gues, as well as of the rfmittents 

 of hot climates, is now believed to be tlie miafmata or effluvia 

 arifing from putrid animal and vegetable fubilances mixed, 

 or from the latter alone. See Dr. Jackfon, &c. on Fever. 



Sir John Pringle accounts for tiiem by means of the 

 principle of putrefaflion. The heat of the body, he ob- 

 ferves, varies little ; and therefore the corruption produced 

 in any of the humours mull happen in a determinate time. 

 If we fuppofe, that in the paroxyfm, the more corrupted 

 particles of the blood do not at all pals oft" through the 

 ikin with the fwcat, but that fome part of them is dif- 

 charged with the bile ; their particles coming into the in- 

 teftines, and being from thence taken up by the lacleals, 

 and carried into the blood, may there aft as a new feiTnent, 

 and occafion a return of the fit. Thus the coiTuption of 

 the bile may be the caufe of the firft fit as well as of thofc 

 that follow. He farther adds, that though all moift coun- 

 tries are fubjeft to agues of fome kind or other ; yet if the 

 moiilure is pure, and the fummers are not clofc and hot, 

 they will moftly be regular tertian agues, and admit an cafy 

 cure. But if the moiilure arifes from long ftagaating 

 water, in which plants, fifhes, and infefts die and rot, then 

 the damps, being of a putrid nature, occafion not only 

 more frequent, but more dangerous fevers, which more 

 commonly appear in the form of quotidians, and double 

 tertians, than that of fingle ones. Accordingly they arc 

 found to vary with the ftafon, on which the degree of pu- 

 trcfaftion in a great meafure depend*. • 



Thefe opinions of Sir John Pringle, as far as they refl 

 on putrefaftive particles, or ferments in the living body, air 

 entertained only by a few pupils of the Bocihaavian fchool. 

 The theories of fever in moft general eftiniation at prefent, 

 are contained in Dr. Darwin's Zoonomia, and Dr. Cullen'* 

 firft lines. 



The fymptoms aie, heavincfs and reaching ; a weak (low 

 pulfe ; coldnefs and fliivering felt firft in the joints, thence 

 creeping over the whole body ; pain in the loins, and an 

 involuntary motion of the under jaw. 



This cold ilage varies in its duration and fcverity with 

 the kind of ague. It is flioiteft in the quotidian, and moft 

 diilrcfTing in the tertian. 



The cold ftage is fucceeded by a full ftrong pulfe, dif-
