30 DISEASES CLASS I. i. 3. 3. 



mucus with great and perpetual hawking occurs in hydrophobia, 

 and is very diftreffing 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 haliily evaporated, and is expec- 

 torated with difficulty in the ftate of white froth. 



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

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

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

 always followed the forcible expuition of the indurated mucus 

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



M. M. Steel-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 flowly fupply moifture, or barley wa- 

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



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

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

 ikin or fcale, owing to the increafed action of the abforbents of 

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

 paiTes into the lungs j 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 can be feen over corn-fields in a hot fummer'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. Expefioratio fotida. Solid expectoration. The mucus 

 of 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 ipit up in the form of branching vefTels, which are 

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

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

 not at firft attended with inflammation. 



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

 polypofa of Michaelis, if they differ from the peripneumony of in- 

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

 piration is great, venefection is immediately neceffary, and then 

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

 upright in bed as much as may be. See Tonfillitis, Clafs II. I.

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



onions,
