Audbhida (lit. begot of the soil) is the name applied to the saline deposit commonly known as the reh efflorescence. It consists "chiefly of sodium chloride and sulphate in varying proportions. In addition there are sometimes carbonate of soda, and we have usually found some magnesian sulphate. In certain localities the last named salt is in very considerable proportion. In other cases nitrate of lime or alkali is present."
