368 DISEASES CLASS IV. 1. 1. 



We shall only add, that the motions of the muscular fibres of 

 the stomach are associated with those of the heart and arteries 

 by direct sympathy, as appears by the weakness of the pulse dur- 

 ing the exhibition of an emetic; and that the absorbents of the 

 stomach are associated with the cellular and cutaneous absorb- 

 ents by reverse sympathy, as is shown by the great absorption 

 of the mucus of the cells in anasarca during sickness; at the 

 same time that the absorbents of the stomach invert their actions., 

 and pour the mucus and water thus absorbed into that viscus. 



In cold paroxysms of fever the stomach partakes of the gene- 

 ral torpor, and vomiting is induced by its debility, either by its 

 association with the torpid capillaries, or other torpid parts, or 

 by its own torpor commencing first, and causing the cold fit. 

 The disordered motions of the stomach frequently seem to be the 

 cause or primary seat of fever as where contagious miasma are 

 swallowed with the saliva, and where fever is produced by sea- 

 sickness, which I once saw. Nevertheless a disorder of the sto- 

 mach does not always induce fever, as in that case it should con- 

 stantly attend indigestion, and vertigo, and sea-sickness; but is it- 

 self frequently induced by association with the disordered move- 

 ments of other parts of the system, as when it arises from gra- 

 vel in the ureter, or from a percussion on the head. 



The connection of the motions of the stomach with irritative 

 ideas, or motions of the organs of sense, in vertigo, is shewn in 

 Sect. XX. and thus it appears, that many circles of association 

 are either directly or reversely associated, or catenated, with this 

 viscus, which will much contribute to unfold some of the symp- 

 toms of fever. 



K. Tertian Associations. 



The third link of associate trains of motion is sometimes actu- 

 ated by reverse sympathy, with the second link, and that by re- 

 verse sympathy with the first link; so that the first and third link 

 may act by direct sympathy, and the intermediate one by reverse 

 sympathy. Of this, instances are given in the singultus nephri- 

 ticus, Class IV. 1. 1. 7. and IV. 2.1. At other times the tertian 

 or quartan links of associate motions are actuated by direct 

 sympathy; and that sometimes forwards and sometimes backwards 

 in respect to the usual order of those trains of associate motions, 

 as in Class IV. 1. 2. 1.
