A fissure was formed extending nearly 9 m.
2 Port Lloyd, the chief anchorage (situated on Peel Island), is considered by Commodore Perry - who visited the islands in 1853 and strongly urged the establishment of a United States coaling station there - to have been formerly the crater of a volcano from which the surrounding hills were thrown up, the entrance to the harbour being a fissure through which lava used to pour into the sea.
Nasal bones large and stout, co-ossified, and standing out freely above the premaxillae, from which they are separated by a deep and wide fissure; the latter small, generally not meeting in the middle line in front, often rudimentary.

The best-known fissure of this character is Almannagjá at Thingvellir.
Fissure after fissure, running with remarkable constancy N.W.
It occurs in its matrix, either in or closely associated with fissure veins or disseminated through rock masses.
A quartz vein or bed of hard rock may show itself as a sharp ridge or as a well-defined bench; a stratum of soft rock or the line of a great fissure, or the weakening of the strata by an anticlinal fold, may produce a ravine or a deep valley.
Its roof is a single flat stratum of limestone; its walls are well marked by lines of stratification; dripstone also partly covers the walls, fills a deep fissure at the end of the cave, and spreads over the floor, where it mingles with an ancient bed of ashes, forming an ash-breccia (mostly firm and solid) that encloses fragments of sandstone, flint spalls, flint implements, charcoal and bones.
The ores are almost exclusively gold, tellurides being the most characteristic form, and occur in fissure veins.
To the left of this is the left lobe of the liver, separated from the quadrate lobe by the umbilical fissure in which lies the round ligament of the liver, the remains of the umbilical vein of the foetus.
' The deep fissure occupied by Lake Baikal would thus appear to consist of two longitudinal valleys connected together by the passage between Olkhon and Svyatoi Nos.
Separating Franconia and Pemigewasset ranges is the romantic Franconia Notch, overlooking which from the upper cliffs of Profile Mountain is a remarkable human profile, The Great Stone Face, immortalized by Nathaniel Hawthorne; here, too, is the Franconia Flume, a narrow upright fissure, 60 ft.
Sometimes this fissure is partly turned into a tunnel by a bridge of liver substance known as the pons hepatis.
The right and left hepatic ducts, while still in the transverse fissure, unite into a single duct which joins the cystic duct from the gall bladder at an acute angle.
The copper is mostly a copper glance passing into chalcopyrite; it is found in fissure veins with granite.
The earlier supposition that these vast lava flows came chiefly from fissure eruptions has been made doubtful by the later discovery of flat-sloping volcanic cones from which much lava seems to have been poured out in a very liquid state.
The lode was an ore channel of great dimensions included within volcanic rocks of Tertiary age, themselves broken through pre-existing strata of Triassic age, and exhibited some of the features of a fissure vein, combined in part with those of a contact deposit and in part with those of a segregated vein.
The posterior boundary of the quadrate lobe is the transverse fissure, which is little more than an inch long and more than half an inch wide.
This fissure represents the hilum of the liver, and contains the right and left hepatic ducts and the right and left branches of the hepatic artery and portal vein, together with nerves and lymphatics, the whole being enclosed in some condensed subperitoneal tissue known as Glisson's capsule.
Behind the transverse fissure the lower end of the Spigelian lobe is seen as a knob called the tuber papillare, and from tree right of this a narrow bridge runs forward and to the right to join the Spigelian lobe to the right Vena cava in its fossa lobe and to shut off the transverse fissure from that for the vena cava.
When these have united the Spigelian lobe re of ductus venosus mental tuberosity ageal groove End of right suprarenal vein Suprarenal impression R; ght end of caudate lobe Uncovered area of right lobe Renal impression Attachment of right lateral ligament Fissu Portal fissure Umbilical fissure Quadrate lobe Portal vein Gall bladder Duodenal impression 0 Oesoph Cohc impressio; From A.
It will be seen that the umbilical fissure (u) divides the organ into right and left halves, as in the lower vertebrates, but that the ventral part of each half is divided into a central and lateral lobe.
(5) The two gill-plates of the left side reflected upwards so as to expose the fissure between foot and gill where the probe g passes.
The Icelandic volcanoes may be divided into three classes: (I) cone-shaped, like Vesuvius, built up of alternate layers of ashes, scoriae and lava; (2) cupola-shaped, with an easy slope and a vast crater opening at the top - these shield-shaped cupolas are composed entirely of layers of lava, and their inclination is seldom steeper than 7°-8°; (3) chains of craters running close alongside a fissure in the ground.
To the left of this is the fissure for the ductus venosus, and to the left of this again, the left lobe, in which a broad shallow groove for the oesophagus may usually be seen.
Fissure between the free edge water forms which carry the young in brood-pouches formed by the ctenidia have suppressed this larval phase.
The other churches are of minor interest; close to that of La Trinita is the Montagna Spaccata, where a vertical fissure from 6 to 15 ft.
In describing the general physical features of the country, the most significant point to notice is that (though it falls westward to the sea and rises eastward to an elevated plain) the rise from west to east is not continuous, but is sharply interrupted by the deep fissure of the Ghor or Jordan valley; which, running from north to south - for the greater part of its length depressed below sea-level - forms a division in the country of both physical and political importance.
Nor was the fissure in the Protestant ranks closed, and Charles took advantage of this disunion to conquer Gelderland and to mature his preparations for overthrowing the league of Schmalkalden.
Fissure or crevice, hence a ravine or narrow valley.
Opium rather than morphine is also usually employed to relieve the pain of haemorrhoids or fissure of the rectum.
Fissidentalium: posterior aperture with long fissure on ventral side; abyssal.
20 it occurs with zinc in reticulated deposits and fissure veins in clays and clastic limestones; and in the third, of which Jasper county is much the most important county, the two metals occur in pockets and joints in the Burlington-Keokuk beds of the sub-Carboniferous.
A well sunk in these formations without striking any fissure or water-bearing flint bed, receives water only at a very slow rate; but if, on the other hand, it strikes one or more of the natural water-ways, the quantity of water capable of being drawn from it will be greatly increased.
With the exception of the Red Marls forming the upper part of the Keuper, most of the New Red Sandstone is permeable, and some parts contain, when saturated, even more water than solid chalk; but, just as in the case of the chalk, a well or borehole in the sandstone yields very little water unless it strikes a fissure; hence, in New Red Sandstone, also, it is a common thing to form underground chambers or adits in search of additional fissures, and sometimes to sink many vertical boreholes with the same object in view.
Any horizontal fissure in a weak place would, in the nature of things, strike somewhere a stronger place, and the final failure would be deferred.
Fissure after fissure, running with remarkable constancy N.W.
In Abyssinia the Ashangi traps are certainly post-Oolitic. In East Africa the fissure eruptions are considered to belong to the Cretaceous.
The Spigelian lobe is represented by a flat surface between the postal fissure and the posterior border, not distinctly marked off from the left lateral by a fissure of the ductus venosus, as this vessel is buried deep in the hepatic substance, but the caudate lobe is distinct and tongue-shaped, its free apex reaching nearly to the border of the right lateral lobe.
The anther consists of lobes containing the minute powdery pollen grains, which, when mature, are discharged by a fissure or opening of some sort.
