ance which such an operation occasions in the 

 qualities and distribution of the blood. It has 

 also been shewn in what manner galvanism 

 maintains the function of digestion. It operates 

 as a stimulus, and tends to remove congestion, 

 whether in the lungs or stomach, and thereby 

 allows the former to oxygenate properly the fluid 

 which it receives ; and this, possessing its usual 

 properties, is transmitted to the viscera of the ab- 

 domen ; the consequence of which is, that the or- 

 ganic functions are supplied with blood calculated 

 to support their action. The truth of this view is 

 found in perusing the cases which WILSON 

 PHILIP himself relates. The immediate effect 

 of galvanism was to relieve the oppressive breath- 

 ing ; and, in those instances in which this was 

 employed, the lungs were comparatively healthy, 

 whereas, in those in which it had not been used, 

 the lungs presented " dark red patches," like the 

 lungs of an animal that had " lain dead' 9 for 

 many hours. 



CCXLVI. In proposition 3d, we may observe, 

 that sensation and motion, variously modified, 

 belong to every part of the system. The univer- 

 sal dissemination of these qualities of matter 

 makes an individual sensible to external agents, 

 and gives him the faculty of removing from, or 

 approaching to such, according as these are pain- 

 ful or agreeable ; and it also binds in harmony 

 the different organs of the body, facilitating mo-
