This is effi i . l>v keeping the yarns separate from each other, and drawing them from revolving bobbins, in order to keep up the twist, while the strand is forming; 2.

By a cylindrical tube, which compresses the strand, and maintains a cylin- drical figure to its surface ; 4. By a gauge, to determine the angle which the yarns in the outside shell make with a line parallel to the centre of tiie strand, when regis- tering ; and, according to the an- gle made by the yarns in this shell, the length of all the yarns in the strand will be determined : lastly, .5. By hardening up the strand, and thus increasing the angle in the outside shell, which compensates for the stretching of the yarns, and compression of the strand. B tending to the yarn in the strand v. ill bear a strain, when at the point of breaking : and, when laid into a rope, it will ac- quire additional strength. CORIANDER, the Common-, or Curiaitariuu sativum, L. is an annual plant, growing in corn- fields, on road-sides, and dunghills. f his vegetable is raised from seed, generally sown in the month of ■i h in the proportion of 14lbs. COR [*i ■ It is also cultivated to- i v, ith caraway and teazel -, but a ! those plauts i up completely and regularly the se- cond year, they an: USU lily allowed to .stand for the third summer. If sown with caraway, the coriander requires great care in hoeing, to aguish it from the former, which is not ! et out for a crop, till the latter is harvested. When I alone, the plants of corian- der are set out from four to six inches apart, and produce whitish flowers that blow i;i June or Julv, and contain two seeds. The leaves of this vegetable have a strong, dis- agreeable smell ; the seeds posa ss -.ant flavour; and, when en- crusted v. ith sugar, are sold by the confectioners, under the name of curia/icier comfits. They have been recommended as carminative and stomachic ; but certainly possess intoxicating, if not deleterious pro- perties : Six drams of them, how- ever, have been taken at one dose, from which Dr. Withering did no; observe any remarkable effect. Coriander seeds are now us( d only in the bitter infusions and preparations of senna, the disag able taste of which they compl overcome. COHK-TREE, or Quercus su- Icr, L. a species of oak indigenous in Spain and Portugal, where it at- tains the height of from CO to 40 feet ; has a thick, rough, fungous bark, and oval serrated leaves, which are downy underneath. The bark of this tree furnish) s that useful materia i, cork ; which, becoming of a thick fungous na- ture, is separated from the trunk, while a new bark is formed under it, which, in the course of six or seven years, is sufficiently thick for harking. Nevertheless, the tree con-
