The diagnosticpoint has been made that pressure with a blunt probewill usually indent the prominent and inelastic abscess,and this dimple will remain visible for sojne time, asshown in Fig. 4183, from Schwartze.

They may burst inward instead of outward(Politzer), a result recognizable by the sudden disappear-ance of the pus and the distensibility of the empty sac onusing the air douche.
