M. M. Cool air, diluents, warm bath, evacuations. 



7. Catarrhus calidus. Warm catarrh. Conilfts in an in- 

 creafed fecretion ci mucus from the noftrils without inflamma- 

 tion. This difeafe, which is called a cold in the head, is fre- 

 quently produced by cold air acting for fome time on the mem- 

 branes, which line the noftrils, as it pafles to the lungs in refpi- 

 ration. Whence a torpor of the aclion of the mucous glands 

 is firft introduced, as in Clafs I. 2. 3. 3. and an orgafm or tit— 

 creafcd action fucceeds in confequence. Afterwards this orgafm 

 and torpor are liable to alternate with each other for fome time 

 like the cold and hot fits of ague, attended with deficient or exu- 

 jberant fecietion of mucus in the noftrils. 



At other times it arifes from reverfe fympathy with fome ex- 

 ienfive parts of the fkin, which have been expofed too long to 

 cold, as Gf the head, or feet. In confequence of the torpor of 

 thefe cutaneous capillaries thofe of the mucous membrane of the 

 noftrils act with greater energy by reverfe fympathy ; and thence 

 fecrete more mucus from the blood. At the fame time the ab- 

 forbents, acting alfo with greater energy by their reverfe fym- 

 pathy with thofe of fome diftant >part of the fkin, abi'orb the 

 thinner parts of the mucus mere haftily ; whence the mucus is 

 both thicker and in greater quantity. Other curious circumftan- 

 ces attend this difeafe ; the membrane becomes at times fo thick- 

 ened by its increafed action in fecreting the mucus, that the pa- 

 tient cannot breathe through his noftrils. In this fituation if he 

 warms his whole fkin fuddenly by fire or bed-clothes, or by 

 drinking warm tea, the increafed action of the membrane ceafes 

 by its reverfe fympathy with the fkin ; or by the retraction of 

 the fenforial power to other parts of the fyftern ; and the patient 

 can breathe agai» through the noftrils. The fame fometimes oc- 

 curs for a time on going into the cold air by the deduction of 

 heat from the mucous membrane, and- its confequent inactivity 

 or torpor. Similar to this when the face and breaft have been 

 very hot and red, previous to the eruption of the fmall-pox by 

 inoculation, and that even when expofed to cool air, I have ob- 

 ferved the feet have been cold ; till on covering them with warm 

 flannel, as the feet have become warm, the face has cooled. See

M. M. Evacuations, abftmence, oil externally on the nofe, 

 Warm diluent fluids, warm fnoes, warm night-cap. 



8. Expectorate call da. Warm expectoration confifts of the 

 increafed fecretion of mucus from the membrane, which -lines 

 the bronchise, or air-cells of the lungs, without inflammation, 

 fhis increafed mucus is ejected by the action of coughing, and
