The machinemay be used either as a dry or a wet mill; its weight isIl kilos., and its height 52 cm.; it is driven by a water-motor similar to those employed for sewing machines, &c.,2—3 atmospheres pressure being sutEcient.

In order toprevent the choking of the filtering medium by depositedmatter, communication is made by a comparalivclv narrowchannel between the two sides of the pump valves; so that,after drawing a charge of liquid into the cyhuder, the returnstroke forces back a small jiortion of the same through theside channel and upward through the filter, which thusbecomes slightly agitated.
