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 refpeet 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 weli as by 

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

 tomed to diftend their itomach by large quantities of animal and 

 vegetable food, and much potation, find a want pi distention, 

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

 miitaken for hunger, but which does not appear to be the ftme 

 fen Tation. I was well informed, that a woman near Litchfield, 

 who eat much animal and vegetable food for a wager, affirmed, 

 that fince diftending her ftomach fo much, me had never fejt 

 herfelf fati.sfied with food ; and had in general taken twice as 

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

 {0 much for a wager. 



3. Naufeaficca. Dry naufe?.. Confifls 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. 1. o. This is fometimes induced bvdifa^veeable 

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

 at other times by the aiTociation 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 fourtii 

 clafs of difeafes. 



M. M. Lemonade. Taftefu! food. A blifter. Warm bath. 



4. JEgritudo ventriculi. Sicknefs of ftomach is produced by 

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

 Sect. XXXV. 1. 3. It confifls in the ftate between the ufual 

 periftaltic motions of that organ, in the digeftion of cur 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 

 ftop, 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 {c^n y and nafty 

 ftories related, as well as by the exhauftion of the fenforial pow- 

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

 the production 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'
