e'^ DISEASES Class 1. 2. 2. 2. 



tremities, without fever, with dry pale fkin, is a fymptom of 

 genera! debility, owing to the decreafed action of the arterial 

 fyftem, and of the capillary vefTels ; whence the perfpirable 

 matter is fecreted in lefs quantity, and in confequence the fkin is 

 lefs warm. This coldnefs is obfervable at the extremities of the 

 limbs, ears, and nofe, more than in any other parts : as a larger 

 furface is here expofed to the contact of the air, or clothes, and 

 thence the heat is more haftily carried away. 



The pain, which accompanies the coldnefs of the fkin, is 

 owing to the deficient exertion of the fubcutaneous vefTels, an4 

 probably to the accumulation of fenforial power in the extremi- 

 ties of their nerves. See Seel. XII. 5. 3. XIV. 6. XXXII. 3* 

 and Clafs I. 2. 4. 1. 



M. M. A blifter. Incitantia, nutrientia, forbentia. Exer- 

 cife. Clothes. Fire. Joy. Anger. 



2. Pallor fugitiv us. The fugitive palenefs, which accompa- 

 nies the coldnefs of the extremities, is owing to a lefs quantity 

 of blood palling through the capillaries of the fkin in a given 

 time 5 where the abforbent power of the veins is at the fame 

 time much diminifhed, a part of the blood lingers at their junc- 

 tion with the capillary arteries, and a bluifh tinge is mixed with 

 the palenefs 5 as is feen in the loofe fkin under the eye-lids, and 

 is always a mark of temporary debility. See Clafs II. 1. 4. 4. 

 Where the palenefs of the fkin is owing to the deficiency of red 

 globules in the blood, it is joined with a yellowiih tinge ; which 

 is the colour of the ferum, with which the blood then abounds, 

 as in chlorofis, and in torpor or paralyfis of the liver, and is of- 

 ten miflaken for a fuperabundance of bile. 



A permanent palenefs of the fkin is owing to the coalefcence 

 of the minute arteries, as in old age. See Clafs I. 2. 2. 9. 

 There is another fource of palenefs from the increafed abforption 

 of the terminations of the veins, as when vinegar is applied to the 

 lips. See Seel:. XXVII. 1. and another from the retrograde 

 motions of the capillaries and fine extremities of the arteries. 

 See Clafs II. 3. 1. 1. 



M. M. A blifler, nutrientia, incitantia, exercife, oxygene gas. 



3. Pus parcius. Diminifhed pus. Drynefs of ulcers. In 

 the cold fits of fever all the fecretions are diminifhed, whether 

 natural or artificial, as their quantity depends on the acYions of 

 the glands or capillaries, which then fhare in the univerfal inac- 

 tion of the fyftem. Hence the drynefs of iffues and blifters in 

 great debility, and before the approach of death, is owing to de- 

 ficient fecretion, and not to increafed abforption. 



M. M. Opium, wine in very fmall quantities, Peruvian bark. 



4. Mucus parcior. Diminifhed mucus. Drynefs of the 



mouth
