It is a rather difficult task to arrange a satisfactory classification of the different varieties of chronic diarrheas due to enterocolonic conditions. This is largely due to the fact that with improved methods of investigation the etiology of hitherto undetermined forms is gradually being made clear, necessitating frequent changes in classification. Since the term "diarrhea" is used only for a symptom denoting the passage of liquid feces, it not only embodies those forms due to disease of the gastro-intestinal tract, but it is also indicative of those varieties due to conditions arising outside of this tract, such as one commonly observes in toxic states, as is seen, for instance, in nephritis or in the disturbances of internal secretion.

I have followed the accompanying classification in the study of my cases, although I recognize fully its incompleteness:

  5. (c) Tuberculous.

  6. (d) Syphilitic.

  7. (e)
