CLASS I. 2. 4. 3. OF IRRITATION. 1Q7 



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

 to conclude, that it is there situated. 



The sense of hunger as well as of thirst, is liable to acquire 

 habits in respect to the times of its returning painfulness, as well 

 as in respect to the quantity required to satiate its appetency, 

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

 want of its appropriate stimulus. Those who have been accus- 

 tomed to distend their stomach by large quantities of animal and 

 vegetable food, and much potation, find a want of distention > 

 when the stomach is empty, which occasions fainlness, and is 

 mistaken for hunger, but which does not appear to be the same* 

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

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

 that since distending her stomach so much, she had never felt 

 herself satisfied with food; and had in general taken twice as 

 much at a meal, as she had been accustomed to, before she eat so 

 much for a wager. 



3. Nausea sicca. Dry nausea. Consists in a quiescence or 

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

 verted motions, described in nausea humida, Class I. 3. 2. 3. 

 In the same manner as sickness of the stomach is a quiescence 

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

 Sect. XXXV. 1. 3. This is sometimes induced by disagreeable 

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

 at other times by the association of these actions with those of 

 the stomach; and thus according to its different proximate 

 causes may belong to this, or to the second, or to the fourth class 

 of diseases.

4. JEgritudo ventriculL Sickness of stomach is produced by 

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

 Sect. XXXV. 1. 3. It consists in the state between the usual 

 peristaltic motions of that organ, in the digestion 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 must 

 stop, before those in a contrary direction can commence. This 

 sickness, like the nausea above described, is sometimes produced 

 by disgustful ideas, as when nasty objects are seen, and nasty 

 stories related, as well as by the exhaustion of the sensorial 

 power by the stimulus of some emetic drugs, and by the defect of 

 the production of it, as in enfeebled drunkards. 



Sickness may likewise consist in the retrograde motions of the 

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

 lymph, which they have lately absorbed, as in Class I. 3. 2. 3. It 

 is probable, that these two kinds of sickness may be different sen-
