COR 



the corn, then apply it in such a way 

 that the corn enters tlu- hole in the plas- 

 ter, and is thus defended against the 

 contact of shoes and stockings. Such a 

 plaster, properly ap])lied, the corn will 

 frequently, in a few Weeks, disappear 

 u ithout any other remedy. If the corn is 

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

 felt sole, so us to fit the corn, is Mitli- 

 cient. When this method .is found in- 

 efficient, rub the com with the volatile 

 liniment, t\vo or three times, in the 



-four hours, keeping- it < 

 in the intervals with an emollient plas- 

 ter. Every morning and evening the 

 foot must be kept in warm water for 

 half an hour, and the corn well nibbed 

 with soap. When softened with the wa- 

 ter, 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.

 cond coat of the eye, so called from its 

 substance, which resembles the horn of

COKNKT, 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 buccinx sound- 

 ed the charge and retreat, and the 

 cornets and trumpets sounded during 

 the course of the battle. 



COHNET, in the military art of the 

 moderns, the third commission officer in

COK\i r< *\'\\, or hornof plenty, among 

 painters, &.c. is represented under the 

 figure of a large horn, out of which issue 

 fniits, 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. 



COR 



COBJCUCOPI.E, 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 Gramina: or Grasses. EMentUkl 

 character: involucre one-leafed, funnel- 

 form, crenate, many-flowered ; calyx 

 t \vo-vulved ; corolla one-valved. There 

 are two species, of which is C. cuculla- 

 tum ; Hooded comucopiae ; 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 

 projecting very far; style connected at 

 the base, spreading in the upper part, 

 twisted, the length of the stamens. Na- 

 tive 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 of Stellatae. Caprifolia, Jus- 

 sieu. Essential character : involucre ge- 

 nerally four-leaved ; petals four superior; 

 drupe with a two-celled nut. There are 

 twelve species, of which C. floridu, great 

 flowered dogwood, seldom rises above 

 seven or oiglitfeut, 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 andthirty feet in the United 

 States --and is one of the most ornamen- 

 tal of our forest trees. The bark of the 

 C. florida, and that or'Cornus sericea, are 

 >cd of tonic powers. They have 

 been used as substitutes for peruvian 

 bark. See Dr. Walker's inaugural dis- 

 sertation. 



COKM'TIA, in botany, a genus of the 

 iVidynamia Gymnospermia class and or 

 der. Natural order of Pet-sonata:. Vitices, 

 .h.s-,',1 11. Essential character: calyx five- 

 toothed; stamina longer than the corolla; 

 .style very long; berry one-seeded. Then: 

 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 (lower- leaves, most com- 

 monly called petals, to distinguish them 

 from the leaves of the plant : according 

 as there is one, two, or three of these pe-
