PATHOLOGY, 



I. Physical: there can be an external de- 

 struction of the cell, organ and organism. 

 The ill starts from without ; the environment 

 crushes in, such as heat, cold, accident. But 

 the physical must pass into the following:

 often a foreign cell enters, a bacillus, and 

 produces the dissociation or disease. Indeed 

 this is the chief field of disease which fluc- 

 tuates variously between the two sides, and 

 can become wholly psychical. The ill of a 

 part attacks the Psyche who is president of 

 the whole organism, which is, therefore, sick, 

 inharmonious with itself. Half the diseases 

 are imaginary, but not the less real for that.. 



III. Psychical: the supreme psychical ill 

 taken by itself is insanity, which has many 

 forms and gradations. 



It need hardly be repeated that all these 

 classes play into one another; Physis and 

 Psyche of the living organism are in direct 

 unity, and the affection of the one cannot help 

 influencing the other. Still the preceding 

 divisions hold good, indicating the chief lo- 

 cality or stress of the ailment. Though only 

 a limb be injured, the man is sick all over; 

 his entire body is disordered through the lit- 

 tle fragment of it. The stone can hardly be
