Dr. Heivetius, Phyfician to the King of Fratur about so Years ago, wrote a Book entirely upon the Subject ot curing Agues by giving the Cortex clyfterwife : In which he pretends," that .his is more Cafe, and no left certain than The Cortex: given internally. Dr. Cockburn, in his Trear.le of Sea 'Dimes, afferts the contrary ; and proves that the Cortex oiven inwardly is asfafe, and by much more certain and expeditious ; and (hews that we know how to remedy all the Inconveniencics the Cortex may occafion.

Dr. Sydenham, and after him M. Reneaume, and others, have prefcrib'd ir with Succefs in Melancholic and Hyttcric AfFeaions, commonly call'd Vapours.. ,_•.,„

Cortex Winter ■aims, or Wmteri, the Bark of a Tree brought from the Streights of Magellan, by Captain Winter, in h?s Voyage with Sir Francs Drake : Clufuts calls the Tree, Mage'llanica Aromatica Arbor. ,""'..

The Bark is Aromatic, and found of good ule at bea aoainft the Scurvy : Half a Dram of it, boil d with other carminative Seeds, (wests, and relieves fcorbutic Patients It has alfo prov'd an Antidote againft a poiionous iort ot Seal, call'd a Sea Lion, frequent in thofe Parts.

The Bark fold in the Shops under the Name ot Cortex Winteranus, or Wild Cinnamon, Dr. Shane obferves, is not the true Cortex Winteranus ; they grow on different _ Trees, and in different Countries, and their Appearance is very different ; yet are they fo like in Tafte, that he thinks they may be ufed as Succedaneums to each other. See Gostus Indicus.

Cortex Caparis. See Caper.

Cortex Cerebri, the cortical or cincntious Subftance ot the Brain. See Cortical, and Brain.

CORTICAL SnbSiance of the Brain, in Anatomy, the exterior Part of the Brain and Cerebellum, or that tart im- mediately under the <Pm Mater ; fo called, becaufe of m inveiting'the inner or medullary Part, as a Bark does a Iree. See Brain. . „ 7 „ c

The fame is alfo call'd the Cinerttiaus Subftance, from its greyifh or afh-colour. See Cineritious;

Archangelo <Pitlholomini, a Ferrarefe, firft introduce! this Diviiion of the Brain into Cortical or Cinentious, and Me- dullary or Fibrous Subftance. See Medulla.

The Cortical Subftance is more foft and moift than the Medullary; and follows or attends it thro' all its Prominences and Sinus's. It is form'd, from the minute Branches ot the Carotid Arteries, interwove in the Meninges, and thence continued hither in infinitely fine Ramifications. SeeMsNiNX.

Moll Anatomifts, after Malpighi, agree in its being glan- dulous, and that the medullary Parts are only a Continuation thereof ; Ruyfch alone excepted : who, from his admirable Skill in IniecHonif, and the Difcoveries he has made there- by, maintainsthatithasnothingglandularinit.

CORVET, or CURVET, in the Manage, an Air, in which the Horfe's Legs are rais'd higher than m the Demi- volt ■ being a kind of Leap up, and a little forwards, where- in the Horfe raifeth both his fore Legs at once, equally ad- vanced, (when he is going ftrait forward, and not in a Cir- cle-) and as his fore-Legs are falling, he immediately rai es his hind-Legs, equally advane'd, and not one before the other ; fo that all his four Legs are in the Air at once ; and as he fets them down, he marks but twice with them. See Air. „ . r

Horfes that are very dull, or very fiery, are improper tor Curvets ; this being the mod difficult Air they can make,

CORYBANTES, in Antiquity, Priefts of Cybck, who danced and caper'd to the Sound of Flutes, and Drums.

Catullus, in his Poem call'd Atys, gives a beautiful Dc- fcription of 'em ; reprefenting them as Madmen. According- ly, Maximus lyrius fays, that thole poffefs'd with the Spirit of Corybantcs, as foon as they heard the Sound of a Flute, were feiz'd with- an Enthuiiafm, and loft the ufe of their Reafon. „ '

Hence, the Gra*jufethe Word n.oso^a.;-na.iv,CorybantiJing, to fignify a Perfon's being tranfported, or poffels'd with a Devil. ,,.

Some fay, the Corybantes were all Eunuchs ; and that tft on this account that Catullus, in his Atys, always ufes fe- minine Epithets and Relatives.

Diadorits Sicuhts remarks, that Corybas Son oi Jaftm and Cybele, paffing into Thrygia with his Uncle Dardanus, there inftituted the Worlhip of the Mother of the Gods, ami gave his own Name to the Priefts. Strabo relates it as the Opinion of fome, that the Corybantes are Children of Ju- piter and Calliope, and the fame with the Cabircs. Others fay, the Word had its Origin from this, that the Corybantcs always walk'd dancing, (if the Expreffion may be allow'd) quod iufiiif\ttm( fainm. Vofftus.

CORXMBIFEROUS 'Plants, are diftmguifh'd into fuch as have a radiate Flower, as the Flos Salts, Calendula, &c. and fuch as have a naked Flower, as the Abrotanum Femimna, Eupatorinm, Artemifia ; to which are added the Corymbi- fcrous Affines, or thofe a-kin hereunto ; fuch as Scabious, Dipfaus, 'Cardials, and the like. See Plant, and Co-

RYMBUS.

CORYMBUS, in the general, fignifies the Top, or Sum- met of any thing ; but among the antient Botaniiis was particularly ufed to exprefs the Bunches or Clutters of Ivy, Berries, SJc.

Some alfo call the Top of the Stalk of a Plant, when 1o fubdivided and adorn'd with Flowers or Fruits, as to make a round fpherical Figure, by rhis Name ; as the Tops of Leeks, Onions, and the like : and others confound the Word with Umbel/a, which expreffeth the flowry Tops of fuch Plants as have their Branches and Flowers fpread round, into the Form of what the Women now call an Umberella.

But among the modern Botanifts, Corymbus is chiefly ufed for a compound difcous Flower, whofe Seeds are not Pap- pous, or do nor fly away in Down : Such arc the Flowers of Dailies, common Marigold, i$c. See Seed.

Mr. Kay, therefore, makes one Genus of Plants to be fuch as have a compound difcous Flower, but without any downy Wings to carry off their Seeds ; as the Corymbife- rous. See Corymbiferous.

CORYPH^iUS, in the antient Tragedy, was the Chief or Leader of the Company that compos'd the Chorus. See Chorus.

The Coryphieus fpoke for all the reft, whenever the Cho- rus took part in the Action, in quality of a Perfon of the Drama, during the Courfe of the Acts.

Hence, the Term has pafs'd into a general Name for the Chief or Principal of any Company, Corporation, Sect, O- pinion, £5?c.

Thus, Euftachitis of Antioch is call'd the Coryphceus of the Council of Nice ; and Cicero calls Zeno. the Coryphieus of the Stoicks.

The Word in the original Greek fignifies Tip oj the Head.

CORYZA, in Medicine, a running at the Nofe ; or a De- fluxion of fharp ferous Humours from the Glands of the Head, arifing upon a diminution of Perfpiration, or catching of Cold. See Cold.

Proper Evacuations, as Bleeding, Epifpafticks, Sternuta- tories, lf>c. are ufual in this Cafe.

COSCINOMANCY, or COSK.INOMANCY, the Art of Divination by means of a Sieve or Riddle. See Divi- nation.

The Sieve or Riddle being fufpended ; after rehcarfing a F annul* of Words, 'tis taken between two Fingers only ; and the Names of the Parties fufpected, repeared : He at whofe Name the Riddle turns, trembles, or ihakes, is repu- ted guilty of the Evil in queftion.

This muft be a very antient Practice : Theocritus, in his third Idyllion, mentions a Woman very fkilful in ir. Ir was fometimes alfo practis'd by fufpending the Riddle by a Thread, or fixing it to the Points of a Pair of Shears, giv- ing it room to turn, and naming, as before, the Parties fuf- pefted : In which laft manner, Cofcinomancy is (till prac- tis'd in fome Parts of England.
