CLASS f. 1. 3. 1. OF IRRITATION. 29 



ORDO I. 



Increased Irritation. 

 GENUS III. 



With Increased Actions of the Absorbent System. 



THESE are not attended wi'th so great increase of heat as in the 

 former genus, because the fluids probably undergo less chemical 

 change in the glands of the absorbent system; nor are the glands 

 of the absorbent vessels so numerous or so extensive as those of 

 the secerning ones. Yet that some heat is produced by the in- 

 creased action of the absorbents appears from the greater gene- 

 ral warmth of the skin and extremities of feeble patients after 

 the exhibition of the Peruvian bark, and other medicines of the 

 article Sorbentia. 



SPECIES. 



1. Lingua arida. Dry tongue occurs in those fevers, where 

 the expired air is warmer than natural; and happens to all those, 

 who sleep with their mouths open; the currents of air in respira- 

 tion increasing the evaporation. There is also a dryness in 

 the mouth from the increased action of the absorbent vessels, 

 the mouth from the increased action of the absorbent vessels, 

 when a sloe or a crab-apple is masticated; and after the perspira- 

 tion has been much increased by eating salt or spice, or after 

 other copious secretions; as after drunkenness, cathartics or 

 fever fits, the mucus of the mouth becomes viscid, and in small 

 quantity, from the increased absorption, adhering to the tongue 

 like a white slough. In the diabetes, where the thirst is very 

 great, this slough adheres more pertinaciously., and becomes black 

 or brown, being coloured after a few days by our aliment or 

 drink. The inspissated mucus on the tongue of those, who sleep 

 with their mouths open, is sometimes reddened as if mixed with 

 blood, and sometimes a little blood follows the expuition of it 

 from the fauces owing to its great adhesion. When this mucus 

 adheres long to the papillae of the tongue, the saliva, which it 

 contains in its interstices, like a sponge, is liable to become pu- 

 trid, and to acquire a bitter taste, like other putrid animal sub- 

 stances; which is generally mistaken for an indication of the 

 presence of bile. 



M. M. Warm subacid liquids. See Class I. 2. 5. 8. 



2. Fauces arid*. Dry throat. The expuition of a frothy
