A fissure was formed extending nearly 9 m.
D, Left (archaic right) gill e, Reflected mantle-flap. fi, The fissure or hole in the mantle-flap traversed by the longitudinal incision.
4), pigeons, gulls, plovers, rails and penguins, have the vomer pointed in front while the maxillo-palatines are free, leaving a fissure between the vomer and themselves.
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.
Sometimes this fissure is partly turned into a tunnel by a bridge of liver substance known as the pons hepatis.
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.
From near the entrance of the optic nerve, through the original choroidal fissure, arises the much-folded pecten, deeply pigmented and very vascular, far into the vitreous humour.
Copper, lead and zinc are produced in small quantities, being found in fissure veins with gold and silver.
It occurs in its matrix, either in or closely associated with fissure veins or disseminated through rock masses.
Fissure after fissure, running with remarkable constancy N.W.
' 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.
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.
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.
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.
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.
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 portal fissure has been slightly opened up to show the vessels passing through it; the other fissures are represented in their natural condition - closed.
The best-known fissure of this character is Almannagjá at Thingvellir.
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.
Africa; Kaptian fissure eruptions; Ashangi traps of Abyssinia.
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.
Shell spiral; mantle and shell with an anterior fissure; two ctenidia; a horny operculum.
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 copper is mostly a copper glance passing into chalcopyrite; it is found in fissure veins with granite.
The ores are almost exclusively gold, tellurides being the most characteristic form, and occur in fissure veins.
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.
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.
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.
70.00 grains 163.39 175.01 1089 06 5106.00 594'46 7388.21 345.80 10 50 317.57 (1) the explanation of a remarkable line of white foam that extends along the axis of the lake amost every morning - supposed by Blanckenhorn to mark the line of a fissure, thermal and asphaltic, under the bed of the lake, but otherwise explained as a consequence of the current of the Jordan, which is not completely expended till it reaches the Lisän, or as a result of the mingling of the salt water with the brackish spring water especially along the western shore; (2) a northward current that has been observed along the east coast; (3) various disturbances of level, due possibly to differences of barometric pressure; (4) some apparently electrical phenomena that have been observed in the valley.
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.
