f wide distribution and is the commonest of the ores of copper. It occurs in metalliferous veins, often in association with iron-pyrites, chalybite, blende, &c., and in Cornwall and Devon, where it is abundant, with cassiterite. The large deposits at Falun in Sweden occur with serpentine in gneiss, and those at Montecatini, near Volterra in the province of Pisa, serpentine and gabbro. At Rammelsberg in the Harz it forms a bed in argillaceous schist, and at Mansfield in Thuringia it occurs in the Kupferschiefer with ores of nickel and cobalt. Extensive deposits are mined in the United States, particularly at Butte in Montana, and in Namaqualand, South Africa. Well-crystallized specimens are met with at many localities; for example, formerly at Wheal Towan (hence the name towanite, which has been applied to the species) in the St Agnes district of Cornwall, at Freiberg in Saxony, and Joplin, Missouri. (L. J. S.) COPPICE, or COPSE (from an O. Fr. _copeis_ or _coupeis_, from Late Lat. _colpare_, to cut with a blow; _colpas_, the Late Lat. for "blow," is a shortened form of _colapus_ or _colaphus_, adapted from the Gr. [Greek: kolaphos]), a small plantation or thicket of planted or self-sown trees, which are cut periodically for use or sale, before the trees grow into large timber. Whether naturally or artificially grown the produce is looked on by the English law as _fructus industrialis_. The tenant for life or years may appropriate this produce (see _Dashwood_ v. _Magniac_, 1891, 3 Ch. 306). COPRA (a Spanish and Portuguese adaptation of the Malay _kopperah_, and Hindustani _khopra_, the coco-nut), the dried broken kernel of the coco-nut from which coco-nut oil is extracted by boiling and pressing. Copra is the form in which the product of the coco-nut is exported for commercial purposes (see COCONUT PALM). COPROLITES (from Gr. [Greek: kopros], dung, and [Greek: lithos], stone), the fossilized excrements of extinct animals. The discovery of their true nature was made by Dr William Buckland, who observed that certain convoluted bodies occurring in the Lias of Gloucestershire had the form which would have been produced by their passage in the soft state through the intestines of reptiles or fishes. These bodies had long been known as "fossil fir cones" and "bezoar stones." Buckland's conjecture that they were of faecal origin, and similar to the _album grecum_ or excrement of hyaenas, was confirmed
