ORDO II. 



Decreafcd Irritation. 



GENUS III. 



With aecriafed Action of the Abforbent Syflem. 



Some decreafe of heat attends thefe difeafes, though in a lefs 

 decree than thofe of the lad genus, becaufe the abforbent fyftem 

 of "glands do not generate fo much heat in their healthy ftate of 

 action as the fecerning fyftem of glands, as explained in Clafs

SPECIES, 



1. Mucus faikium frigidus. Cold mucus from the threat-' 

 filuch mucus, of rather a faline tafte, and lefs infpifTated than 

 ufual, is evacuated from the fauces by hawking, owing to the 

 deficient abforption of the thinner parts of it. This becomes a 

 habit in fome elderly people, who are continually fpitting it out 

 of their mouths ; and has probably been brought on by taking 

 inuff, or fmoking tobacco -, which by frequently Simulating the 

 fauces have at length rendered the abforbent veffels lefs excita- 

 ble by the natural ftimulus of the faline part of the fecretion, 

 "which ought to be reabforbed, as fcon as fecreted. 



M. M. A few grains of powder of bark frequently put into 

 the mouth, and gradually difrufed over the fauces. A gargle of 

 barley water. 



2. Sudor frigidus. The cold dampnefs of the hands of fome 

 people is caufed by the deficient abforption of perfpirable matter % 

 the clammy or vifcid feel of it is owing to the mucous part being 

 left upon the (kin. The coldnefs is produced both by the de- 

 creafed action of the abforbent fyftem, and by the evaporation of 

 a greater quantity of the perfpirable matter into the air, which 

 ought to have been abforbed. 



M. M. Warn the hands in lime water, or with a fmall quan- 

 tity of volatile alkali in wafer. 



3. Catarrhus frigidus. The thin difcharge from the noftrils 

 in cold weather. The abforbent vefTels become torpid by the 

 diminution of external heat, fooner than the fecerning ones, 

 which are longer kept warm by the circulating blood, from 

 which thev fe'ect the fluid they fecrete ; whereas the abforbent
