COR 



the corn, then apply it in such a way 

 that the corn enters the hole in the plas- 

 ter, and is thus defended against the con- 

 tact of shoes and stockings. Such a plas- 

 ter, properly applied, the corn will fre- 

 quently, in a few weeks, disappear with- 

 out any other remedy. If the corn is at 

 the bottom of the foot, a hole cut in a felt 

 sole, so as to fit the corn is sufficient. 

 When this method is found inefficient, 

 rub the corn with the volatile liniment two 

 or three times, in the twenty -four hours, 

 keeping it covered in the intervals with 

 an emollient plaster. Every morning and 

 evening the foot must be kept in warm wa- 

 ter for half an hour, and the corn well rub- 

 bed with soap. When softened with the 

 water, it should be scraped with a blunt 

 knife till the soft part is removed, and till 

 the operation begins to give pain. This 

 treatment is to be continued till the corn 

 is entirely extirpated. 



CORNEA tuiuca, in anatomy, the se- 

 cond coat of the eye, so called from its 

 substance, which resembles the horn of a 

 lanthorn. See EYE. 



CORNET, in the military art of the 

 ancients, an instrument much in the na- 

 ture of a trumpet, which when it only 

 sounded, the ensigns were to march 

 alone, without the soldiers ; whereas, 

 when the trumpet only sounded, the 

 soldiers were to move without the en- 

 signs. The cornets and buccinae sound- 

 ed the charge and retreat, and the cor- 

 nets and trumpets sounded during the 

 course of the battle. 



CORNET, in the military art of the mo- 

 derns, the third commission officer in a 

 troop of horse or dragoons. This is a 

 very honourable post : he commands in 

 the lieutenant's absence ; his principal 

 duty being to carry the standard, near 

 the middle of the first rank of the squa- 

 dron. 



CORNEUS, the name by which Lin- 

 naeus calls a kind of tin ore, found in 

 black columns, with irregular sides, and 

 terminating in prisms. See TVS. 



CORNICE. That part of the entabla- 

 ture which rests upon the frize. See AR- 

 CHITECTURE. 



CORNUCOPIA, or horn of plenty, among 

 painters, &c. is represented under the 

 figure of a large horn, out of which issue 

 fruits, flowers, &c. Upon medals the 

 cornucopia is given to all deities, genii, 

 and heroes, to mark the felicity and 

 abundance of all the wealth procured by 

 the goodness of the former, or the care 

 and valour of the latter. 



GORMTCOPIJJ, in botany, so called from 

 the manner in which the flowers grow 

 within their involucre, like a cornucopia, 

 or horn of plenty, a genus of the Trian- 

 dria Digynia class and order. Natural 

 order of Graminae or Grasses. Essential 

 character: involucre one-leafed, funnel- 

 form, crenate, many flowered; calyx two- 

 valved ; corolla one-valved. There are 

 two species, of which is C. cucullatum, 

 hooded cornucopias, the root of this is 

 annual, fibrous, and branched; culms 

 numerous, ascending, jointed, smooth, 

 branched, leafy, dark purple at the 

 joints ; flowers several, arising from the 

 sheaths of the upper leaves ; calyx and 

 corolla striated, obtuse ; filaments pro- 

 jecting very far ; style connected at the 

 base, spreading in the upper part, twist- 

 ed, the length of the stamens. Native of 

 the vales about Smyrna, whence it was 

 sent to England. 



CORNUS, in botany, a genus of the Te- 

 trandria Monogynia class and order. Na- 

 tural order ofStellatx. Caprifolix, Jus- 

 sieu. Essential character : involucre ge- 

 nerally four-leaved; petals four superior; 

 drupe with two-celled nut. * There are 

 twelve species, of which C. florida, great 

 flowered dogwood, seldom rises above 

 seven or eight feet, and is generally fur- 

 nished with large leaves. It does not 

 flower here very plentifully, nor does it 

 produce berries in. England, though it is 

 very hardy. This tree attains the height 

 of twenty-five and thirty feet in the Unit- 

 ed States, and is one of the most ornamen- 

 tal of our forest trees. The bark of the 

 C. florida, and that of Cornus sericea, are 

 possessed of tonic powers. They have 

 been used as substitutes for Peruvian 

 bark. See Dr. Walker's inaugural dis- 

 sertation. 



CORNUTIA, in botany, a genns of the 

 Didynamia Gymnospermia class and or- 

 der. Natural order of Personatae. Vitices, 

 Jussieu. Essential character : calyx five- 

 toothed ; stamina longer than the corolla ; 

 style very long ; berry one-seeded. There 

 are two species, viz. C. pyramidata, 

 hoary-leaved cornutia; and C. quinata; 

 the former is a native of the West Indies, 

 Campeachy, and la Vera Cruz, the latter 

 of China, in the woods near Canton. 



COROLLA, among botanists, the most 

 conspicuous part of a flower, surrounding 

 the organs of generation, and composed 

 of one or more flower-leaves, most com- 

 monly called petals, to distinguish them 

 from the leaves of the plant ; according 

 fts tkere is one, two, pr three of these pe-
