lard the ground" as they run. The increafe of heat of corpulent 

 people on exercife, is another confequence of their more rapid 

 circulation, and greater fecretion. See Clafs I. 2. 3. 17. 



Other caufes of difficult or quick refpiration will be treated 

 of under Afthma, Pertuffis, Peripneumonia, Tonfillitis. 



5. Tujfis ebriorum. Senfitive cough is an exertion of the 

 muides ufed in expiration excited into more violent action by 

 the fenforial power of fenfation, in confequence of fomething 

 which too powerfully ftimulates the lungs. As the faline part 

 of the fecreted mucus, when the abforptionof it is impeded ;or 

 the too great vifcidity of it, when the abforption is increafed ; 

 or the too great quantitiy of the mucus, when the fecretion is 

 increafed ; or the inflammation of the membranes of the lungs ; 

 it is an effort to diflodge any of thefe extraneous materials. 



Of this kind is the cough which attends free-drinkers after a 

 debauch \ it confifts of many (hort efforts to cough, with a fre- 

 quent expuition of half a tea-fpoonful of frothy mucus, and is 

 attended with confiderable third. The third is occafioned by 

 the previous diflipation of the aqueous parts of the blood by fen- 

 fible or infenfible perfpiration ; which was produced by the in- 

 creafed action of the cutaneous and pulmonary capillaries during 

 the dimulus of the wine. In confequence of this an increafed 

 abforption commences to replace this moiflure, and the ikin and 

 mouth become dry, and the pulmonary mucus becomes infpiffa- 

 ted -, which ftimulates the bronchia, and is raifed into froth by 

 the fucceflive currents of air in evacuating it- This production 

 of froth is called by fome free-drinkers " fpitting fixpences" af- 

 ter a debauch. This fubfequent third, dry mouth, and vifcid 

 expectoration in fome people fucceeds the flighted degree of in- 

 toxication, of which it may be efteemed a criterion. See Clafs 

 IV. 2. 1. 8. 



As coughs are not always attended with pain, the mufcular 

 actions, which produce them, are fometimes excited by the fen- 

 forial faculty of irritation, as in Clafs I. 1. 2. 8. I. 1. 3. 4. 

 I. 1. 4. 3. I. 2. 3. 4. Coughs are alfo fometimes convulfive, 

 as in Clafs III. 1. 1. 10. and fometimes fympathetic, as in Clafs 

 IV. 2. 1. 7. 



M. M. Venefection, when the cough is attended with in- 

 flammation. Mucillages. Opium. Torpentia. Blifter. 



6. Singultus. Hiccough is an exertion of the mufcles ufed 

 in infpiration excited into more violent action by the fenforial 

 power of fenfation, in confequence of fomething which too pow- 

 erfully ftimulates the cardia ventriculi, or upper orifice of the 

 ftomach. As when folid food is too baftily taken without fuf- 

 ficient dilution. And is an effort to diilodge that offenfive ma-
