30 DISEASES Class I. i. 3. 3. 



mucus with great and perpetual hawking occurs in hydrophobia, 

 and is very diftreiTing to the patient ; which may be owing to 

 the increafed irritability or fenfibility of the upper part of the 

 cefophagus, which will not permit any fluid to reft on it. 



It affects fome people after intoxication, when the lungs re- 

 main flightly inflamed, and by the greater heat of the air in ex- 

 piration the mucus becomes too haltily evaporated, and is expec- 

 torated with difficulty in the ftate of white froth. 



I knew a perfon, who for twenty years always waked with his 

 tongue and throat quite dry ; fo that he was neceffitated to take 

 a fpoonful of water, as foon as he awoke 5 otherwife a little blood 

 always followed the forcible expuition of the indurated mucus 

 from his fauces. See Oafs II. 1.3. 17. 



M. M. Stecl-fprings fixed to the night-cap fo as to fufpend the 

 lower jaw and keep it clofed •, or fprings of elaftic gum. Or a 

 pot of water fufpended over the bed, with a piece of lift, or 

 woollen cloth, depending from it, and held in the mouth ; which 

 will act like a fyphon, and ilowly ftipply moifture, or barley wa- 

 ter mould be frequently fyringed into the mouth of the patient. 



3. Naves aridi. Dry noftrils with the mucus hardening up- 

 on their internal furface, fo as to cover them with a kind of 

 fkiti or icale, owing to the increafed action of the abforbents of 

 this membrane j or to the too great drynefs of the air, which 

 paffes into the lungs ; or too great heat of it in its expiration. 



When air is fo dry as to lofe its tranfparency \ as when a trem- 

 ulous motion of it tan be feen over corn-fields in a hot fumrner's 

 day ; or when a dry mift, or want of tranfparency of the air, is 

 vifible in very hot weather \ the fenfe of fmell is at the fame 

 time imperfect from the drynefs of the membrane, beneath which 

 it is fpread. 



4. ExpeSoratio jbibtl >. Solid expectoration. The mucus 

 cf the lungs becomes hardened by the increafed abforption, fo 

 that it adheres and forms a kind of lining in the air-cells, and is 

 fometimes fpit up in the form of branching vefTeis, which arc 

 called polypi of the lungs. See Tranfadt. of the College, Lon- 

 don. There is a rattlmg or wheezing of the breath, but it is 

 not at fir ft attended with inflammation. 



The Cynanche trachealis, or Croup, of Dr. Cullen, or Angina 

 polypofaof Michaelis, if they differ from the pcripneumony of in- 

 fants, feem to belong to this genus. When the difficulty of ref~ 

 piration is great, venelection is immediately neceflary, and then 

 an emetic, and a blifter. And the child fhould be kept nearly 

 upright in bed as much as may be. See Tonfilhtis, Clafs II. 1. 

 3.3. and II. 1. 2. 4. 



M. M. Diluents, emetics, elTence of antimony, foetid gums, 



onions,
