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

 : with which it is frequently combined. 



M. M. Inhaling the (team of warm water, evacuations, warm 

 bath, afterwards opium, forbentia. 



9. Exfiuiatio pvie aures. A difcharge behind the ears. This 

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

 from its fetcr ; for if it was owing to defect of abforption, it 

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

 a confiderable time, it (hould not be flopped too fuddenly ; fmce 

 in that cafe fome other morbid action is liable to fucceed in its 

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

 convulfions, confequeBt 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 facl, which I have frequently obierved ; 

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

 power ofdigeftion, and removes the heart-burn in adults, and 

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

 ienfation in theveiTels of the fkin \ with this additional fenfori- 

 al power thefe veflels acl: more flrongly \ and with thefe the vef- 

 fels of the internal membranes of the ftomach and bowels ac~l 

 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 fkin, and fo far acts as a fmall blif- 

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

 power of the ftomach fucceeds from the want of this accuilom- 

 ed ftimulus, with flatulency, green flools, gripes, and fometimes 

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



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

 lymphatics of the neck, it mould be cured as foon as poffible by 

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

 and to prevent any ill confequence an iffiie {hould be kept for 

 about a month in the arm j or a purgative medicine {hould 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 warning them with 

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

 them ; eipecially till the time of toothing is pail. The tinea, or 

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

 the ears, are different difeafes. 



10. GonorrKtiea calida. Warm gleet. Increafed difcharge of 

 mucus from the urethra or proftrate gland without venereal de- 

 lire, or venereal infection. See Clafs I. 2. 3. 8. 



M. M. Camharidcs, balfams, rhubarb, biifler on perineum, 



cold
