contains carbonate and phosphate of lime, carbonate of soda, charcoal, and iodine. It is used in bronchocele, scrofulous affections, and herpetic eruptions; and its good effects seem to be dependent upon iodine. It is made by cutting sponge into pieces, and heating it, that any ex-traneous matter may be separated; burning it in a close iron vessel until it becomes black and friable, and, lastly, rubbing it into very fine powder.-Ph.
