Carbon as a purifying agency is well known ; but its application as a filtrator of gas and an illuminative power diffuser is comparatively new. Mr. Arthur employs it in his patent " carbon gasburner," and if his statements are correct, his burners arc, from the simplicity of their con- shru tine, les:s liable to get out of order than any at present in use. Siiauld the carbon become clogged with the impurities of the gas, it has only to be removed from the shell and put in the fire for a minute, and it becomes again as useful as ever.
