CLASS I. 2. 4. 3. OF IRRITATION, 107 



and the pain of hunger being felt in that part, gives great reafon 

 to conclude, that it is there iituated. 



The fenfe of hunger as well as of thirft, is liable to acquire 

 habits in refpect to the times of its returning painfulnefs, as well 

 as in refpect to the quantity required to fatiate its appetency, 

 and hence may become difeafed by indulgence, as well as by 

 want of its appropriate flimulus. Thofe who have been accuf- 

 tomed to diftend their ftomach by large quantities of animal and 

 vegetable food, and much potation, find a want of diftenticn, 

 when the ftomach is empty, which occafions faintnefs, and is 

 miltaken for hunger, but which does not appear to be the fame 

 fenfation. I was well informed, that a woman near Litchfield, 

 who eat much animal and vegetable food fora wager, affirmed, 

 that fince diftending her ftomach fo much, (he had never felt 

 herfelf fatisfied with food ; and had in general taken twice as 

 much at a meal, as (he had been accuftomed to, before (he eat 

 fo much for a wager. 



3. Naufeajicca. Dry naufea. Confifts in a quiefcence or 

 torpor of the mucous or falivary glands, and precedes their in- 

 verted motions, defcribed in naufea humida, Clafs I. 3. 2. 3. 

 In the fame manner as ficknefs of the ftomach is a quiefcence 

 of that organ preceding the action of vomiting, as explained in 

 Sect. XXXV. i. 3. This is fometimes induced by difagreeable 

 drugs held in the mouth, at other times by difguftful ideas, and 

 at other times by the affociation of thefe actions with thofe of 

 the ftomach ; and thus according to its different proximate 

 caufes may belong to this, or to the fecond, or to the fourth 

 clafs of difeafes. 



M. M. Lemonade. Tafteful food. A blifter. Warm bath. 



4. JEgritudo ventriciili. Sicknefs of ftomach is produced by 

 the quiefcence or inactivity of that organ, as is explained in 

 Sect. XXXV. i. 3. It confifts in the (late between the ufual 

 periftaltic motions of that organ, in the digeftion of our aliment 

 and the retrograde motions of it in vomiting ; for it is evident, 

 that the direct motions of it from the cardia to the pylorus muft 

 flop, before thofe in a contrary direction can commence. This 

 ficknefs, like the naufea above defcribed, is fometimes produced 

 by difguftful ideas, as when nafty objects are feen, and nafty 

 (lories related, as well as by the exhauftionof the fenforial pow- 

 er by the ftimulus of fome emetic drugs, and by the defect of 

 the produdtion of it, as in enfeebled drunkards. 



Sicknefs may likewife confift in the retrograde motions of the 

 lymphatics of the ftomach, which regurgitate into it the chyle or 

 lymph, which they have lately abforbed, as in Clafs I. 3. 2. 3. It 

 is probable, that thefe two kinds of ficknefs may be different fen- 



fations*
