An organized marine substance, of the Class Porifera, met with in many seas, but especially in the Mediterranean and Arabian. It is supple, elastic, porous, and capable of absorbing fluids in which it may be placed, and of thus increasing in size. It is employed in surgery, for cleansing or washing; for absorbing acrid discharges from ulcers; suppressing hemorrhage when the mouth of the vessel can be compressed by it, and for forming tents for dilating wounds; in which case, the sponge is immersed in melting wax, and cooled before being used, It is then called Spongia cera'ta, Waxed, Cera'ted or Prepared Sponge or Sponge Tent.
