The fourth effusion is pus, which is form- ed in cellular textures, or between serous membranes, when inflammation has reach- ed its utmost limit. It always affords evi- dence of the preceding stage, which is ne- cessary to it, and is manifested by the pre- sence of coagulable lymph, as well as of pus.
