or six hundred and forty felins, or four 

 thousand six hundred and eight grains. 

 In Holland the mark-weight is also called 

 troy-weight, and is equal to that of France. 

 When gold and silver are sold by the 

 mark, it is divided into twenty-four ca- 

 racts. | See CARACT. 



M AUK is also used among us for a mo- 

 ney of account, and in some other coun- 

 tries for a coin. The English mark is 

 two thirds of a pound sterling, or thirteen 

 shillings and four-pence, and the Scotch 

 mark is of equal value in Scotch money 

 of account The mark-lubs, or Lubeck- 

 rnark, used at Hamburgh, is also a money 

 of account, equal to one-third of the rix- 

 dollar, or to the French livre : each mark 

 is divided into sixteen sols-lubs. Mark- 

 lubs is also a Danish coin equal to sixteen 

 sols-lubs. Mark is also a copper and sil- 

 ver coin in Sweden. 



MARKET, the establishment of public 

 marts or places of buying and selling, with 

 the tolls belonging to it, is enumerated as 

 one of the King's prerogatives, and mar- 

 kets can only be set up by virtue of the 

 King's grant, or by immemorial usjage. 



All sales and contracts, of any thing 

 saleable in markets overt, will not only be 

 good as between the parties, but binding 

 also upon all persons having any property 

 therein. 



In London, every shop in which goods 

 are exposed publicly to sale, is market 

 overt for such things only as the owner 

 professes to trade in ; though if the sale 

 be in a warehouse, and not publicly in the 

 shop, the property is not altered ; but if 

 goods are stolen from one, and sold out 

 of the market overt, the property is not 

 altered, and the owner may take them 

 wherever he finds them. If a man buy 

 his own goods in a market, the contract 

 shall not bind him, unless the property 

 had been previously altered by a former 

 sale. 



MARLE, in mineralogy, is divided into 

 two sub-species, viz. the earthy marie, 

 and the indurated marie: the former is of a 

 yellowish grey colour, principally employ- 

 ed for improving bad land. It is found in 

 Thuringia. The latter is grey ; it occurs 

 massive ; the lustre is dull ; it is opaque, 

 soft, so as to yield to the nail, easily fran- 

 gible, and not very heavy ; it melts be- 

 fore the blow-pipe into a blackish kind of 

 *glass ; it effervesces with acids ; it occurs 

 in beds in the fioetz lime-stone, and in- 

 dependent coal formations ; in the first it 

 alternates with beds of lime-stone, and 

 sometimes occurs in nests of it. It is 

 found in the coal works near Dresden, 

 an$ is employed in improving bad land ; 



as also mortar, and where lime-stone *s 

 not easily had, in the smdting of ores of 

 iron. In the business of agriculture, 

 marie is distinguished into the common, 

 which includes the earthy marie, and 

 some varieties of potters' clay; stone- 

 marie, which is the earthy indurated ; 

 slate marie, which is the slaty indurated ; 

 shell-marie, which is either the earthy or 

 indurated, abounding with shells. Mr. 

 Jameson says, it passes into lime-stone 

 and indurated clay, and according as alu- 

 mina or silica preponderates, it receives 

 the name of clay or lime marie. 



MARQUE, or Letters of Marque, in mi- 

 litary affairs, are letters of reprisal, grant- 

 ing the subjects of one prince or state li- 

 berty to make reprisals on those of an- 

 other. Letters of marque, among us, are 

 extraordinary commissions granted by au- 

 thority, for reparation to merchants tak- 

 en and despoiled by strangers at sea ; and 

 reprisals is only the retaking, or taking 

 of one thing for another. In the prose- 

 cution of these letters there must be, 1. 

 The oath of the person injured, or other 

 sufficient proof, touching the injury sus- 

 tained. 2. A proof of due prosecution 

 for satisfaction in a legal way. 3. The 

 deferring or denial of justice. 4. A com- 

 plaint to his own prince or state. 5. A 

 requisition of justice made to the su- 

 preme head of the state. After all which, 

 letters of reprisal, under certain restric- 

 tions, are issued; but if the supreme 

 power think these letters of reprisal may 

 affect the peace of the state, they are put 

 off till a more convenient time. 



MARQUETRY, or INLAID work, is a 

 curious work composed of several fine 

 hard pieces of wood, of various colours, 

 fastened in thin slices on a ground, and 

 sometimes enriched with other matters, 

 as silver, brass, tortoise-shell, and ivory ; 

 with these assistances, the art is now ca- 

 pable of imitating any thing ; whence it 

 is by some called the art of painting in 

 wood. 



The ground on which the pieces are to 

 be arranged and glued, is usually of well 

 dried oak or deal, and is composed of se- 

 veral pieces glued together, to prevent 

 its warping. The wood to be used in 

 marquetiy is reduced into leaves, of the 

 thickness of a line, or the. twelfth part of 

 an inch, and is either of its natural co- 

 lour, or stained, or made black, to form 

 the shades by other methods : this some 

 perform by putting it in sand heated very 

 hot over the fire : others by steeping it 

 in lime water and sublimate ; and others 

 in oil of sulphur. The wood being of the 

 proper colours, the contours of the pieces
