FRANKLINITE , a member of the See also:

spinel See also:group of minerals, consisting of oxides of See also:iron, See also:manganese and See also:zinc in varying proportions, (Fe, Zn, Mn) "(Fe, Mn) 2"'O4. It occurs as large octahedral crystals often with rounded edges, and as granular masses. The See also:colour is iron-See also:black and the lustre metallic; hardness 6, specific gravity 5.2. It thus resembles See also:magnetite in See also:external characters, but is readily distinguished from this by the fact that it is only slightly magnetic. It is found in consider-able amount, associated with zinc minerals (See also:zincite and See also:willemite) in crystalline See also:limestone, at See also:Franklin See also:Furnace, New See also:Jersey, where it is See also:mined as an ore of zinc (containing 5 to 20% of the See also:metal); after the extraction of the zinc, the See also:residue is used in the manufacture of spiegeleisen (the See also:mineral containing 15 to 20% of manganese oxides). Associated with franklinite at Franklin Furnace, and found also at some other localities, is another member of the spinel group, namely, gahnite or zinc-spinel, which is a zinc aluminate, ZnAl2O4, with a little of the zinc replaced by iron and manganese. See also:FRANK-See also:MARRIAGE (liberum maritagium), in real See also:property See also:law, a See also:species of See also:estate tail, now obsolete. When a See also:man was seized of See also:land in See also:fee See also:simple, and gave it to a daughter on marriage, the daughter and her See also:husband were termed the donees in frank-marriage, because they held the land granted to them and the heirs of their two bodies See also:free from all manner of service, except fealty, to the donor-or his heirs until the See also:fourth degree of See also:con-sanguinity from the donor was passed. This right of a freeholder so to give away his land at will was first recognized in the reign of See also:Henry II., and became up to the reign of See also:Elizabeth the most usual See also:kind of See also:settlement.
