With regard to Princes, the ^»r;r or Belly has been

fomctimes crown'd, in form.

Venter, or Belly of a Mufcle, is the flelhy or body Part thereof; as contradiftinguilh'd from the two Tendons, its Extremes ; one whereof is call'd the Heed, and the other the fail of the Mufcle. See Muscle.

Venter DraconiS, Dragon's Belly, in Aftronofny, the middle of a Planet's Orbit ; or that Part mod remote from the Nodes, i. e. from the Dragon' s-Head and Tail ; being the Part which has the greateft Latitude. See Orbit, and Node.

The Moon has five Degrees of Latitude, when in the Dragon's Belly, and is 90 Degrees diflant from the Nodes. See Latitude.

Of thefe two Points, in each Orbit, that towards rhe South is alfo call'd the Southern Limit, and that towards the North, the Northern Limit. See Limits.

Venter Equinns, or Horfe's Belly, among Chymifts, is a Dunghi!, wherein are enclofed certain Veflels for particu- lar Operations to be perform'd by means of the gentle heat thereof. See Fire, and Heat.

Venter, in our Cuftoms, is ufed for a Partition of the Effects of a Father and Mother, among Children born, or accruing from different Marriages.

This Partition is fo order'd, as that a fingle Child of one Marriage, or Venter, takes as much as feveral of another Marriage, or Venter : In order to which, the Eftate is di- vided into fo many Parts as there have been Venters, or Marriages.

Venter is alfo ufed for the Children whereof a Woman is deliver 'd at one pregnancy.

Thus, two Twins are faid to be of the fame Venter.

Many People take for a Fable what is related of the Coun- ted of Holland, vis,, that Ihe had 3*5 Children at one Ven- ter, all living, and baptized : and yet the Story is very gravely related by abundance of Authors ; and the Font or Bafon is {till ftiewn in the Church where they were baptiz'd; with a kind of Monument of the Fact, thereon. See Foetus.

VENTIDUCTS, in Building, call'd by the Italians Veu- tidotti, and by the French frifons des Vents, or Calais d'Eole ; are Spiracles, or fubterraneous Places, where frefh, cool Winds being kept, are made to communicate, by means of Ducts, Funnels, or Vaults, with the Chambers or other Apartments of a Houfe ; to cool them in fultry Weather.

Thefe are much in ufe in Italy, &c. See Building, House, &c.

VENTOSITY, in Medicine. See Flatulency.

VENTRE Infpiciendo, a Writ for the fearch of a Woman that fays Ihe is with Child, and thereby holds Land from him that is otherwife next Heir at Law.

VENTRICLE, a. d. Little Belly, in Anatomy, a Di- minutive of Venter ; fignifying a Cavity fmaller than what we exprefs by a Venter ; or rather, fignifying a Divifion of a Vcnrer ; or fome fmalier Cavity, contain'd in a larger. See Venter.

There are two Cavities in the Heart, adjoining to the Auricles ; and four in the Brain ; call'd Ventricles ; which fee explain'd tinder the Articles Heart, and Brain.

The right Ventricle of the Heart, in relaxing, admits the Blood by the right Auricle from the Cava ; and contrac- ting, drives it out into the pulmonary Arteries : The left, receiving the Blood by the left Auricle, from the Lungs, drives it out into the Aorta. See Cava, Aorta, and Lungs; fee alfo Systole, Diastole, Circulation, &c.

Ventricle, or Ventriculus, byway of Eminence thus call'd, is the fame thing with the Stomach. See Stomach.

VENTRILOQUOUS, Ventriloojtus, call'd alfo Gaf- triloquous, and Engaflrimythus, a Term applied to Perfons who form their Speech by drawing the Air into the Lungs; fo that the Voice proceeds out of the Thotax ; and, to a By-ftandcr, fecms to come from a diftance. See Engas-

TRlMYTHUS, £5>C.

Such a Perfon we had lately in London, a Smith by Pro- feffion, who had the Faculty m fuch Perfection, that he'd make his Voice appear, now, as if it came out of the Cel- lar, and the next Minute, as if in an upper Room ; and no body prefent perceive that he fpoke at all : Accordingly, he has frequently call'd a Perfon firft up, then down Stairs ; then out of doors, then this way, then that, without ftirring from his Seat, or appearing to fpeak at all. - Rolandus, in his AgloJJoflomcgraphia, mentions, that if the Mediaftintun, which is naturally a fingle Membrane, be divided into two Parts, the Speech will feem to come out of the Breaft ; fo that the By-flanders will fancy the Perfon poffefs'd. See Engastrimander.

VENUS, in Attronomy, one of the inferior Planets ; de- noted by the Character ?. See Planet.

Venus is eafily diftinguifh'd by her brightnefs, which ex- ceeds that of all the other Planets, and which is fo confide- rable, that in a very dark Place Hie projeas a fenfible Sha- dow. Her Place is between the Earth and Mercury.

She conftantly attends the Sun, and never departs from him above 47 Degrees : When the goes before the Sun, that is, rifes before him, She is call'd 'Pbofphorus, or Lucifer, or the Morning Star ; and when (lie 'follows him, that is, lets after him, Hefperus, or Vefper. See Phosphorus, Ves- pek, (gc.

The Semidiamcter of Venus, is to that of the Earth, as 10 to 19 ; her Djttance from the Sun is f?4„ of the Earth's diftance from the Sun : her Excentricity 5 ; the Inclination of her Orbit 3 23'. See Inclination, Excentricity, &C.

Her periodical Courfe round the Sun, is perform'd in 224 Days 17 Hours ; and her Motion round her own Axis, in 23 Hours. See Period, and Revolution.

Her greateft Diftance from the Earth, according to Caf- fim, is 58000 Semidiamcrers of the Earth ; and her fmall- eft tfooo. See Distance.

Her Parallax is 3 Minutes. See Parallax.

Venus, when view'd thro' a Telefcope, is rarely feen to fhine with a full Face, but has Phafes juft like thofe of the Moon ; being now gibbous, now horned, %$c. and her illu- min'd Part conftantly tutn'd towatds the Sun, /'. e. it looks towatds the Eaft when "Pbofphorus, and towards the Weft when Hcfficrus. See Phases.

T)e la Hire, in 1700, thro' a Telefcope of 15 Feet, difco- vet'd Mountains in Venus; which he found to be larger than thofe in the Moon. See Moon.

And CaJJini and Campanl, in the Tears 15*5 and 1666, difcover'd Spots in her Face : from the Appearances of which, he ai'certain'd her Motion round her Axis. See Spots.

Sometimes the is feen in the Diflt of the Sun, in form of a dark, round Spot. See Transit.

In i6'72, and i6%6, CaJJini, with a Telefcope of 34 Feet, thought he faw a Satellite moving round this Planet, and diftant from it about \ of Venus's Diameter. It had the fame Phafes as Venus, but without any well defin'd Form 5 and its Diameter fcarce exceeded | of that of Venus.

Dr. Gregory thinks it more than probable that this was a Satellite ; and luppofes theReafon why it is not ufually feen, to be the unfitnefs of its Surface to reflect the Rays of the Sun's Light ; as is the Cafe of the Spots in the Moon : of which, if the whole Diflt of the Moon were compos'd, he thinks, that the Planet could not be feen as far as to Venus. See Satellite.

The Phenomena of Venus, evidently fhew the Falfity of the Ptolemaic Syftem : For that Syftcm fuppofes, that Venus's Orb, or Heaven, enclofes the Eatth ; pafling be- tween the Sun and Mercury. And yet all our Obfervations agtee, that Venus is fometimes on this fide the Sun, and fometimes on that ; nor did ever any body fee the Earth be- tween Venus and the Sun : which yet muft frequently hap- pen, if Venus revolved round the Earth in a Heaven below the Sun. See System, Earth, ££c

Venus, in Chymiftry, is ufed for the Metal Copper. See Copper.

Its Character is S ; which, fay the Adefti, expreffes it to be Gold, only join'd with fome corrofive and arfenical Menftruum ; which removed, Copper would be Gold. See Gold.

Venus is univerfally allow'd, by the Chymifts, i£c. to be one oi the moft powerful Medicines in Nature : Of this, is faid to have been compos'd the famous Butler's Stone, which cured moft Difeafes by only licking it. Of this is com- pos'd that noble Remedy of Van Helmont, viz. the Sulphur of Vitriol, or Ens Vitrioli, fix'd by Calcination, and Coho- bation.- — Of the Ens Vitrioli of Venus, is likewife com- pofed Mr. Boyle's Arcanum, the Colcothar Vitrioli. See Vi- triol.

'Tis cettain, Copper is a moft excellent Emetic, and a

noble Antidote againft Poiions ; for it is no fooner taken

than it exerts its force : whereas other Vomitories lie a
