The stacking of the tetrahedral and octahedral sheets in the chrysotile structure has been shown to yield three types of chrysotile fibers: clino-chrysotile: monoclinic stacking of the layers, x parallel to fiber axis, most abundant formortho-chrysotile: orthorhombic stacking of the layers, x parallel to fiber axispara-chrysotile: two layer structure, 180° rotation of two-layer structures, y parallel to fiber axis

The crystals are monoclinic, P2I, with two molecules in the unit cell, and X-ray photographs, taken of them with copper Ka-radiation show very markedly the effects of anomalous dispersion

Calcium metasilicate, CaSiO_3, occurs in nature as monoclinic crystals known as tabular spar or wollastonite; it may be prepared artificially from solutions of calcium chloride and sodium silicate.

Having determined the identity in chemical composition of the crystals, it was thought that there might be a difference of form of the crystals in the various plants, from the fact that calcium oxalate crystallizes both in the tetragonal and the monoclinic systems.

To prepare the pure base a very concentrated solution of this pure hydrochlorate is treated with an excess of a very concentrated solution of caustic soda, and pieces of caustic potash are added, whereupon the free alkaloid separates out at first as a colorless resinous stringy mass, which, however, upon standing, turns crystalline, forming monoclinic crystals similar to tartaric acid or glycocol.

The rhombic crystals that characterize sulphur at ordinary temperatures and pressures, give place to monoclinic crystals at 95.5 degrees C. Sulphur thus exists with two crystalline forms whose stability depends directly upon the temperature.

_Calcium nitrate_, Ca (NO_3) _2·4H_2O, is a highly deliquescent salt, [v. 04 p. 0972] crystallizing in monoclinic prisms, and occurring in various natural waters, as an efflorescence in limestone caverns, and in the neighbourhood of decaying nitrogenous organic matter.
