Infiammation. 11 



Tlie redness and swelling round tlie end of the finger may 

 be taken as illustrating an acute inflammation. It was, however, 

 an acute exacerbation rather than a simple acute inflammation. 

 The increased size of the nail indicates the previously congested 

 condition of the parts, and may be taken as an instance of 

 overgrowth from increased vascularity. G. C. 3125,
