The lime which drops into the chamber t,may be removed therefrom through the manhole w. states that a considerable saving is effected in thelime, owing to each particle or atom being kept in mo-tion, and falling repeatedly through the gas in its passage .from one end of the tube to the other, and that there is also a great saving in labor. Another form of wet purifier, which might also be advantageously used as a scrubber,or as u naphthalizer, has recently been invented by M. Colladou of Geneva, and is now iuVol. III.—25. 686 COAL-GAS. 188
