"Hexagonal" Quotes from Famous Books



... unable to build in their usual instinctive manner, beginning from above and working downwards; on this they began building from below, and again horizontally. The outermost cells that spring from the top of the hive or abut against its sides are not hexagonal, but pentagonal, so as to gain in strength, being attached with one base instead of two sides. In autumn bees lengthen their existing honey cells if these are insufficient, but in the ensuing spring they again shorten them in order to get greater roadway between ...

... retort fused completely. In other experiments lumps of lime, sand, and corundum were fused, with indications of a reduction of the corresponding metal; on cooling, the lime formed large, well-defined crystals, the corundum beautiful red, green, and blue hexagonal crystals. ...

... faithfulness—as all-inclusive. They are the two which are often jointly ascribed to God, especially in the Psalms. Our attitude to one another should be moulded in God's to us all. The tiniest crystal has the same facets and angles as the largest. The giant hexagonal pillars of basalt, like our Scottish Staffa, are identical in form with the microscopic crystals of the same substance. God is our Pattern; goodness is ...

... species (C. myrtifolia), and two or three varieties of the common species, have been known to produce hexagonal and imperfectly quadrangular flowers; and the branches producing such flowers have been propagated by grafting. (11/17. 'Gardener's Chronicle' 1847 page 207.) The Pompon variety often bears "four distinguishable kinds of flowers,—the pure white and the red-eyed, which appear ...

... nine miles in a W. N. W. direction to latitude 16 degrees 0 minutes 26 seconds, over many Bauhinia plains with the Bauhinias in full blossom. The stiff soil of these plains was here and there marked by very regular pentagonal, hexagonal, and heptagonal cracks, and, as these cracks retain the moisture of occasional rains better than the intervening space, they were fringed with young grass, which showed these mathematical figures very distinctly. We passed a great number of dry ...

... taste, but which, to an educated eye and mind only, conveys a lively idea of ostentation. When you call upon a gentility-monger, a broad-shouldered, coarse, ungentlemanlike footman, in Aurora plushes, ushers you to a drawing-room, where, on tables round, and square, and hexagonal, are set forth jars, porcelain, china, and delft; shells, spars; stuffed parrots under bell-glasses; corals, minerals, and an infinity of trumpery, among which albums, great, small, and intermediate, must by no means ...

... Giovanni Fuorcivitas, and it is the beautiful work of his son Giovanni we see in the great pulpit of S. Andrea, where you enter by a door carved in 1166 by Gruamonte with the Adoration of the Magi. Unlike the work of Fra Guglielmo in S. Giovanni, the pulpit of S. Andrea is hexagonal, and there Giovanni has carved in high relief the Birth of Our Lord, the Adoration of the Magi, the Murder of the Innocents, the Crucifixion, and the Last Judgment. They were carved in 1301, before Giovanni ...

... edge of the crater (see Fig. 23), and was formerly extensively quarried in underground caverns for millstones. Here the rock is a vesicular trachyte, of a greyish colour, solidified in vertical columns of hexagonal form, about four feet in diameter, and traversed by transverse joint planes. These quarries have been worked from the time of the Roman occupation of the country; and, before the introduction of iron or steel rollers for grinding ...

... may modify the form obtained. In the case of sodium dihydrogen phosphate, NaH2PO4.H2O, a stable rhombic form is obtained from warm solutions, while a different, unstable, rhombic form is obtained from cold solutions. Calcium carbonate separates as hexagonal calcite from cold solutions (below 30 deg.), and as rhombic aragonite from solutions at higher temperatures; lead and strontium carbonates, however, induce the separation of aragonite at lower temperatures. From supersaturated solutions ...

... appeared to consist of nothing but the same strange, uniform mineral conglomerate, crystallized into regular hexagonal prisms. But whatever was its geological character, it was only too evident that it had entirely replaced the former soil, so that not a vestige of the old continent of Europe could be discerned. The lovely scenery of Provence, with the grace of its rich and ...

... pyramid.[201] I have already quoted Olafsen's observations on the polygonal lining which he saw on the surface of the ice in the Surtshellir. The French Encyclopaedia [202] relates that M. Hassenfratz saw ice served up at table at Chambery which broke into hexagonal prisms; and when he was shown the ice-houses where it was stored, he found considerable blocks of ice containing hexahedral prisms ...

... was grateful enough to carry out in a very sumptuous manner the last wishes of its benefactor, who desired to be commemorated by a monument in the style of the later Scaliger tomb at Verona, and from the designs of Frauel was erected the hexagonal Gothic pavilion, surmounted by an equestrian statue of the Duke, which is so well known to architects. The Veronese prototype of the monument is a tolerably insecure affair, but the modern imitation is ...

... the idealization of quilt-piecing is given also by the quaint descriptive names applied to the various patterns. Of those the "Rising-sun," "Log Cabin," and "Job's Trouble" are perhaps the most familiar. "Job's Trouble" was simply honeycomb or hexagonal blocks. "To set a Job's Trouble," was to cut out an exact hexagon for a pattern (preferably from tin, otherwise from firm cardboard); to cut out from this many hexagons in stiff brown paper or letter paper. These were covered with the bits of calico with the edges turned under; the sides were ...

... crews and all. Again, as Marcellus removed his ships a little distance, the old man gave all the Syracusans the power to lift stones of a wagon's size, and letting them go one by one to sink the ships. When Marcellus withdrew a bow shot thence, the old man manufactured a kind of hexagonal mirror, and at an interval proportionate to the size of the mirror he set similar small mirrors with four edges, moving by links and by a kind of hinge, and made the glass the center of the rays of the sun,—its noontide ray, whether ...

... of quartz, rock crystal, white and colored sands, agate, jasper, flint, etc.; test their hardness with a knife blade, and see whether they will scratch glass. Notice that quartz crystals are hexagonal or six-sided prisms, terminated by hexagonal pyramids. The coloring matters are impurities, often Fe and Mn, if red or brown. When pure, quartz is transparent as glass, infusible except in the oxy- hydrogen blow- pipe, and harder than glass. Rock crystal is massive Si02. Sand is generally ...

... sensitive to discordant sounds, he must have had a musical ear; his chief aversion was the sound of a gong, the beater for which was too hard and, unless very carefully manipulated, produced a jangle. My hall was paved with hexagonal stone sections called "quarries," which appeared to intensify the discordance. Chips felt it keenly, and would stand quite rigid for some minutes until the last reverberation and its effect had passed off. He was uncertain in temper ...
