 of the sinus. When the sinuses or their divisions are 

 filled with pus, percussion applied to the outer walls 

 causes a dull sound to be emitted. If there is any 

 doubt about the confinement of pus in the cavity the 

 introduction of a small gimlet or drill, will when 

 withdrawn, contain pus in the groove if there be any 

 present.

 gelding. The animal presented the following symp-
