450 THEORY OF FEVEH. Su*. !. 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- 

 pressed, so as to form half a cylinder, to give a greater aper- 

 ture for the emission of air from the larynx, and the edges of 

 it become thus as much exposed to the currents of air as the 

 middle parts of it. 



3. When the internal capillaries or glands sympathize with 

 the cutaneous capillaries; or when any of them are previously 

 affected with torpor, and the external or cutaneous capillaries 

 are affected secondarily; other symptoms are produced, which 

 render the paroxysms of fever still more complicate. Thus if the 

 spleen or pancreas are primarily or secondarily affected, so as to 

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

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

 tit. These in some intermittent fevers are perceptible to the 

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

 ing to the permanent torpor of the absorbent system, the secern- 

 ing vessels continuing to act some time afterwards. If the se- 

 cretory vessels of the liver are affected first with torpor, and af- 

 terwards with orgasm, a greater secretion of bile is produced, 

 which sometimes causes a diarrhoea. If a torpor of the kidneys, 

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

 by sympathy with the cutaneous capillaries, the urine is in small 

 quantity and pale, as explained in Class I. 2. 2. 5.; and if these 

 secretory vessels of the kidneys, and the absorbents of the blad- 

 der act more strongly than natural afterwards by their increased 

 irritability or associability, the urine becomes in larger quantity, 

 and deeper coloured, or deposites its earthy parts, as in Class I. 1 . 

 2. 4. which has been esteemed a favourable circumstance. But 

 if the urine be in small quantity, and no sediment appears in it, 

 after the hot fit is over; it shews that the secerning vessels of 

 the kidneys and the absorbent vessels of the bladder have not 

 regained the whole of their activity, and thence indicates a 

 greater tendency to a return of the cold fit. 



4. When the stomach is affected with torpor either primarily; 

 or secondarily by its sympathy with the cutaneous capilla- 

 ries; or with some internal viscus; sickness occurs, with a total 

 want of appetite to any thing solid; vomiting then supervenes, 

 which may often be relieved by a blister on the skin, if the skin 

 be cool and pale; but not if it be hot and flushed. The intes- 

 tines cease to perform their office of absorption from a similar 

 torpor; and a diarrhoea supervenes owing to the acrimony of 

 their putrid, or of their acid contents. The loose undigested or 

 fetid stools indicate the inability of the intestines to perform 

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