4$o THEORY OF FEVER. Sup. I. 2. 3. 



the tongue are liable to be as much furred as the middle of it ; 

 as during the action of coughing the middle of the tongue is de- 

 preffed, lb as to form half a cylinder, to give a greater aperture 

 for the emiihon of air from the larynx •, and the edges of it be- 

 come thus as much expofed to the currents of air as the middle 

 parts of it. 



3. When the internal capillaries or glands fympathize with 

 the cutaneous capillaries ; or when any of them are previoufly 

 affected with torpor, and the external or cutaneous capillaries 

 are affected fecondarily; other fymptoms are produced, which ren- 

 der the paroxyfms of fever it 111 more complicate. Thus if the 

 fpleen or pancreas are primarily or fecondarily affected, fo as to 

 be rendered torpid or. quiefcent, they are liable to become en- 

 larged, and to remain fo even after the extinction of the fever- 

 fit. Thefe in fome intermittent fevers are perceptible to the 

 hand, and are called ague-cakes ; their tumour feems to be ow- 

 ing to the permanent torpor of the abforbent fyflem, the fecern- 

 ing vefiels continuing to act fome time afterwards. If the fe- 

 cretory veiTels of the liver are affected firlt with torpor, and af- 

 terwards with orgafm, a greater fecretion of bile is produced, 

 which fometimes caufes a diarrhoea. If a torpor of the kidneys, 

 and of the abforbents of the bladder occurs, either primarily, or 

 by fympathy with the cutaneous capillaries, the urine is in fmall 

 quantity and pale, as explained in Ckifs I. 2. 2. 5. j and if thefe 

 fecretory veiTels of the kidneys, and the abforbents of the bladder 

 act more {trongly than natural afterwards by their increafed irri- 

 tability or aiTociability, the urine becomes in larger quantity, and 

 deeper coloured, or depofits its earthy parts, as in Clafs I. 1.2. 

 4. which has been eiteemed a favourable circumftance. But if 

 the urine be in fmall quantity, and no fediment appears in it, af- 

 ter the hot fit is over ; it ihews that the fecerning veiTels of the 

 kidupvs and the abforbent veiTels of the bladder have not regain- 

 ed the whole of their activity, and thence indicates a greater 

 tendency to a return of the cold fit. 



4. When the ftomach is affected with torpor either primari- 

 ly ; or fecondarily by its fympathy with the cutaneous capilla- 

 ries ; or with fome internal vifcus ; ficknefs occurs, with a total 

 want of appetite to any thing folid ; vomiting then fupervenes, 

 which may often be relieved by a Milter on the {kin, if the ikin 

 be cool and pale •, but not if it be hot and fluihed. The intef- 

 tines ceafe "to perform their office of abforption from a fimilar 



orpdr ; and a diarrhoea fupervenes owing to the acrimony of 

 their putrid, or of their acid contents. The loofe undigefted or 

 fetid ftoois indicate the inability of the inteitines to perform 

 their proper office ; as the mucus and gaftric acid, which are 



vomited
