438 DISEASES OF IRRITATION. SECT. XXXII. 9 : 



i>le, that his experiments were made at the be- 

 ginning of the fubfequent hot fits; which com- 

 mence with partial diftrifeutions of heat, owing to 

 fome parts of the body regaining their natural 

 irritability fooner than others. 



From the quiefcence of the anaftomoflng capil- 

 laries a palenefs pf the fkin fucceeds, and a lefs 

 fecretion of the perfpirable matter ; from the qui- 

 efcence of the pulmonary capillaries a difficulty 

 of refpiration arifes ; and from the quiefcence of 

 the other glands lefs bile, lefs gaftric and pancrea- 

 tic juice, are fecreted into the ftomach and intef- 

 tines, and lefs mucus and faliva are poured into 

 the mouth ; whence arises the dry tongue, cof- 

 tivenefs, dry ulcers, and paucity of urine. From 

 the quiefcence of the abforbent fyflem arifes the 

 great thirft, as lefs moifture is abibrbed from the 

 atmofphere. The abforption from the atmofphere 

 was obferved by Dr. Lyfter to amount to eighteen 

 ounces in one night, above what he had at the 

 fame time infenfibly perfpired. See Langrifh, 

 On the fame account the urine is pale, though in 

 fmall quantity,' for the thinner part is not abforbed 

 from it; and when repeated ague fits continue 

 long, the legs fwell from the diminifhed 'abforp- 

 tion of the cellular abforbents. 



From the quiefcence of the inteftinal canal a 

 lofs of appetite and flatulencies proceed. From 

 the partial quiefcence of the glandular vifcera a 

 fuelling and teniion about the pr2ecordia becomes 

 fenfible to the touch ; which is occafioned by the 

 delay of the fluids from the defel of venous or 

 lymphatic abforption. The pain of the forehead, 

 and of the limbs, and ef the fmall of the back, 

 arifes from the quiefcence of the membranous 

 fafcia, or mufcles of thofe parts, in the fame man- 

 ner as the Ikin becomes painful, when the vefiels, 

 of which it is compofed, become quiefcent from
