Mud-bath definition

This species chiefly frequents swampy grass jungle and is fond of a mud-bath.

While water containing much saline matter, and more especially water containing free carbonic acid, has a very stimulating action upon the skin, mud has a sedative effect, so that in a mud-bath one feels a pleasant soothing sensation as if bathing in cream.

This mud bath is in fact a cleaning process which can be used to cool them down.
