Class I. i. 2. 9. OF IRRITATION. Ij 



is called a cold, and refembles the catarrh of the preceding arti- 

 cle ; v/ith which it is frequently combined. 



M. M. Inhaling the fleam of warm water, evacuations, warm 

 bath, afterwards opium, forbeiitia, 



9. Exfudatio pone aures. A difcharge behind the ears. This 

 chiefly affects children, and is a morbid fecretion ; as appears 

 from its fetor \ for if it was owidg to defect of abforption, it 

 would be laiine, and not fetid ; if a morbid action has continued 

 a considerable time, if mould not be ftopped too fuddenly ; fince 

 in that cafe fome other morbid action is liable to fuccecd in itsl 

 fiead. Thus children are believed to have had colics, or even 

 convulfions, confequent to the too fudden healing of thefe mor- 

 *bid effufions behind their ears. The rationale of this is to be ex°> 

 plained from a medical fact, which I have frequently observed ; 

 and that is, that a blifter on the back greatly ftrengthens the 

 power of digeflion, and removes the heart-burn in adults, and 

 green (tools in children. The ftimulus of the blifter produces 

 fenfation in thevefTels of the fkin r. with this additional fenfori- 

 al power thefe veiTels acT more ftrongly ; and with thefe the vef- 

 iels of the internal membranes of the ftomaeh and bowels act 

 with greater energy from their direct fympathy with them. 

 Now the acrid difcharge behind the ears of children produces 

 fenfation on that part of the (kin, and fo far acts as a fmall blis- 

 ter. When this is fuddenly flopped, a debility of the digeftive 

 power of the ftomaeh fucceeds from the want of this accuftom- 

 ed ftimulus, with flatulency, green ft ools, gripes, and fometimes 

 confequent convulfions. See Clafs II. 1. 5. 6. and II. 1. 4. 6. 



M. M. If the matter be abforbed, and produce fweiling of the 

 lymphatics of the neck, it lhould be cured as foon as pombleby 

 dufting the part with white lead, ceruifa, in very fine powder ; 

 and to prevent any ill confequence an iflue mould be kept for 

 about a month in the arm ; or a purgative medicine mould be 

 taken every other day for three or four times, which mould con- 

 fift of a grain of calomel, and three or four grains of rhubarb, 

 and as much chalk. If there be no appearance of abforption,, 

 it is better only to keep the parts clean by wafhing them with 

 warm water morning and evening j or putting fuller's earth on 

 them ; efpecially till the time of toothing is part. The tinea, or 

 fcald head, and a leprous eruption, which often appears behind 

 ihe ears, are different difeafes. 



10. Gonorrhea cc.Iida. Warm gleet. Iricreafed difcharge of 

 mucus from the urethra or proftrate gland without venereal de- 

 £re, or venereal infection. See Clafs I. 2. 3. 8. 



M. M. Cantharjdes, balfams, rhubarb > blifter on perineeurn,
