Ciiss I. 2. 3. 1. OF IRRITATION. 81 



ORDO II. 





Decreased Irritation* 

 GENUS III. 



With decreased Action of the Absorbent System. 







SOME decrease of heat attends these diseases, though in a le&s 

 degree than those of the last genus, because the absorbent system 

 of glands do not generate so much heat in their healthy state of 

 action as the secerning system of glands, as explained in Class 

 I. 1. 3. 



SPECIES, 



1. Mucus faucium frigidus. Cold mucus from the throat, 

 Much mucus, of rather a saline taste, and less inspissated than 

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

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

 habit in sonle elderly people, who are continually spitting it out 

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

 snuff, or smoking tobacco; which, by frequently stimulating the 

 fauces, have at length rendered the absorbent vessels less excita- 

 ble by the natural stimulus of the saline part of the secretion, 

 which ought to be reabsorbed, as soon as secreted. 



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

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

 barley water* 



2. Sudor frigidus. The cold dampness of the bands of some 

 people is caused by the deficient absorption of perspirable matter; 

 the clammy or viscid feel of it is owing to the mucus part being 

 left upon the skin. The coldness is produced both by the de- 

 creased action of the absorbent system, and by the evaporation of 

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

 ought to have been absorbed. 



M. M. Wash the hands in lime water, or with a small quan- 

 tity of volatile alkali in water. 



3. Catarrhus frigidus. The thin discharge from the nostrils 

 in cold weather. The absorbent vessels become torpid by the 

 diminution of external heat, sooner than the secerning ones, 

 which are longer kept warm by the circulating blood, from 

 which they select the fluid they secrete; whereas the absorbent
