Hewlett, Maurice Henry
Maurice Henry (1861-), an English author. He was born in London and received his education at the London International College. He studied law and was admitted to the bar. His first published volume was Earthwork out of Tuscany, which appeared in 1895. Several volumes relating to life in Italy during the middle ages followed. His first popular story was The Forest Lovers, of which James Lane Allen says that its "style alone is an extraordinary achievement." Life and Death of Richard Yea-and-Nay is a glowing romance of the Crusaders and Richard Coeur de Lion . The Queen's Quair is a story of Mary, Queen of Scots. The archaic language used in some of Hewlett's stories makes them difficult reading.

Hexagon
a six-sided plane figure. A regular hexagon has six equal sides and six equal angles. The length of a side is exactly equal to the distance from the center to an angle. It is one of the three regular geometrical figures that may be placed together to fill an area completely. The other two are the triangle and the square. If circles be brought together by equal pressure from all sides, those in the interior will assume the form of a hexagon. Cylinders piled up like cordwood, whether on the side or on end, and subjected to pressure, become six-sided. This is the shape of the prisms of basalt rock formed by the cooling of lava under pressure. The bee builds six-sided cells. See Geometry

Hexagonal System
in crystallography and mineralogy, one of the six great systems of crystallization. It agrees with the tetragonal system in having only the lateral axes equal, but differs in having three equal lateral axes instead of two. The vertical is at right angles to the lateral one. The symmetry of the crystals is by sixes and twelves.

Hexane
in chemistry, C6H14, five isomeric hydrocarbons exist. (1) Normal hexane. Dipropyl, CH3-CH2-CH2- CH2-CH2CH3. It occurs in the light oils obtained by the distillation of cannel coal, also in petroleum. It can be obtained by the action of sodium and normal propyl iodide, CHI, or by the action of zinc and hydrochloric acid on secondary hexyl iodide (from mannite), and by distilling suberic acid with baryta, CgH14O4 + 2BaO = 2BaCO3 + C6H14. It boils at 71°. (2) Propyl dimethy methane, or propyl isopropyl, ethyl isobutyl, obtained by the action of sodium on a mixture of ethyl iodide and isobutyl iodide.

Hexyl Alcohols
in chemistry, monatomic alcohols having the formula C8H13 (OH). Seventeen alcohols can exist, eight primary, six secondary, and three tertiary. Normal hexyl-alcohol, (CH3(CH2)CH2OH. It is obtained from the essential oil of Heracleum giganteum, where it exists semitone, as hexylbutyrate, along with octyl-acetic; the oil is saponified by alcoholic potash, and then fractionally distilled. The hexylalcohol boils at 157°.
