Other thanthe grinding-niill and press, chemical means havebeen used for extracting oils from sicds, nuts, grain,fruit; also oil from wool. The seeds or nuts areciushed or giouud, immersed in bisulphide of car-bon, which extracts the oil and resin they contain,but leaves the substance otherwise unaltered. Thesolution is then removed, the bisulphide distilledoff, leaving the oil, like the raw oils extracted bypressure, contaminated to some degree with resinousand coloring matters, which are removed by a sec-ond process of refining. This process was invented by Moison of Mouy, inFrance, and used by him in cleansing wool from the Fig. MoismCs Apparatus JvT rfinortng Oil from ^yool. suint, as also from the greaise and tar with whichthe sheep had been treated or marked. It wasafterward adopted to separate oils, fats, ami resinsfrom the substances with which they are combined,and for su]iplementing the mechanical processes byoperating upon oil-cake, the marc of olives, etc. In Jloisons process the wool to be subjected totreatment is introduced into a cast-iron cylinder a,surrounded by a jacket into wdiich steam may beconducted when it is necessary to raise the tempera-ture. 214 pounds of wool are placed in this cylin-der at once. Within the cylinder is a false bottomperforated with numerous holes, with a small freespace beneath it. Upon the top of the wool isplaced a circular follower o
