Abstract
8804. Thom, T. M. April 26. Stone, artificial.-Blocks of lime are submitted to the action of carbon dioxide in a partial vacuum instead of under pressure as heretofore. Thus, the blocks are placed in a chamber, a vacuum of about 27 inches is produced, and then gas is allowed to enter from time to time so as to maintain the vacuum at nearly 5 inches.
