PART II. 



OF NEUROSES, OR NERVOUS DISEASES. 



MXC. In a certain view, almost the whole of the diseases of 

 the human body might be called NERVOUS ; but there would be 

 no use for such a general appellation ; and, on the other hand, 

 it seems improper to limit the term, in the loose inaccurate 

 manner in which it has been hitherto applied, to hysteric or 

 hypochondriacal disorders, which are themselves hardly to be 

 defined with sufficient precision. 



MXC I. In this place, I propose to comprehend, under the 

 title of NEUROSES, all those preternatural affections of sense or 

 motion which are without pyrexia, as a part of the primary dis- 

 ease ; (" we do not exclude from the present class those affec- 

 tions in which pyrexia may be present, as fever with apo- 

 plexy ;") and all those which do not depend upon a topical affec- 

 tion of the organs, but upon a more general affection of the 

 nervous system, and of those powers of the system upon which 

 sense and motion more especially depend. 



" By excluding organic affections (morbus localis), we mean 

 to confine the term Neuroses to the affections of the sensorium 

 that have manifestly a mutual near relation, while the several 

 organic diseases are more frequently affections of other parts 

 than the nerves. There are in this some difficulties, but such

MXCIL Of such diseases I have established a class, under 

 the title of NEUROSES or NERVOUS .DISEASES. These I again dis- 

 ti nguish, as they consist, either in the interruption and debility 

 of the powers of sense and motion, or in the irregularity with
