Between the two sets of diaphragms are inter-posed rods of iron, which are connected to the negativepole of the apparatus. The filtering diaphragms, con-taining the negative liquid arc arranged in such a mannerthat the pressure of the liquid may be varied, so as toregulate the rapidity of filtration through the diaphragms. —B.

Augier. Fr. ,028, April 5, Sltf*- ?.\\ The peat, which supplies the carbon for the manufactureof carbon bisulphide, is led up an inclined tube, surroundedby a jacket containing water at 50°—60° (.. by means of ahelical conveyor: this brings it ti 1 the top of the carbonisingchamber, which is of truncated conical shape. The peatdescends down this on to a large plate, pierced with holes,covered by baffles : if is kept in motion by a rotating ver-tical shaft on which conical projections arc fixed. I bonising chamber is heated by the heat arising from anelectric furnace containing molten iron, which has been ob-tained from a suitable mineral (eg., mareasite or chalco-pyrite), the sulphur vapour arising therefrom being ledthrough the holes in the plate above mentioned, where they 1022 JOURNAL OF THE SOCIETY OF CHEMICAL INDUSTRY.
