ArTEE the consideration of the diseases embraced within the 

 present section, the reader will doubtless experience great 

 difficulty in perceiving that clear line of demarcation, which 

 might naturally be supposed to exist between one malady and 

 another, affecting the same class of organs. Several of the 

 diseases in question bear a close general resemblance to each 

 other, and not unfrequently one imperceptibly terminates in 

 another of a similar but more severe character. Two, or even 

 three of these diseases may affect the patient at the same time ; 

 so that, to the inexperienced observer, the whole may present 

 an assemblage of peculiarities of the most inextricable con- 

 fusion.
