Ex-tensively cultivated in this, as well as in other Europeancountries, both for its fibre for making thread, and for itsoil obtained from the seeds. Description.—The seed of the flax, commonly termedlinseed or lintseed {semina lini) is small (about a linelong), oval, oblong, flattened on the sides with acute edges, pointed at one ex-.

The seed coat is mucilaginous ; the nucleusoily. The cake (placenta lini) left after the expression of the oil, is usuallydenominated oil cake ; it forms, when ground to a fine powder, linseed meal(farina lini). The best oil cake for the preparation of linseed meal is the Eng-lish fresh made. Foreign cake is of inferior quality. The colour of linseed mealis grayish-brown. It abounds in mucilage. The meal prepared by grinding theunpressed seeds, yields a considerable quantity of oil. The substance lermedjlax is prepared from the fibrous portions of the bark ofthe plant. (See Ures Diet, of Arts, p. 482.) The short fibres which are re-moved in heckling constitute tow (stupa), which is employed both in pharmacyand surgery. Of flax is made linen (linteum), which, when scraped
