The origin of slaty cleavage is in some measure obscure.

The connexion of cleavage with pressure, however, is unmistakable.

They lose their facile cleavage and become hard, dark-coloured, slightly lustrous rocks, which have a splintery character or break into small cuboidal fragments.

It will be observed that the cleavage planes do not pass through the white bands.

The cleavage of the ovum follows two types, both seen in Tubularia (Brauer [3]).

The hardness is 2 -3; smooth cleavage surfaces can be just scratched with the finger-nail.

In all this there was no apparent line of cleavage between "La Gironde" and the Mountain.

The development of foliation in shaly rocks is undoubtedly closely akin to the production of cleavage in slates.

In the Thallophytes the cytoplasm may be segmented by constriction, due to the in-growth of a new cell wall from the old one, as in Spirogyra and Cladophora, or by the formation of cleavage furrows in which the new cell-wall is secreted, as occurs in the formation of the spores in many Algae and Fungi.

It consists in an unequal number of chromosomes passing over to each of the daughter nuclei, so that one may become hypochromatic, the other hyperchromatic. When this happens the resulting cleavage of the cytoplasm and nucleus is also unequal.

On examining more minutely the course of the development, it is found that the ovum goes through the usual process of cleavage, always total and regular in this group, and so gives rise to a hollow sphere or ovoid with the wall composed of a single layer of cells, and containing a spacious cavity, the blastocoele or segmentation-cavity.

Twinned crystals are not common, but the presence of polysynthetic twinning is sometimes shown by fine striations running diagonally or obliquely across the cleavage surfaces.

Mention may also be made here of clausthalite (lead selenide, PbSe) and altaite (lead telluride, PbTe), which, with their lead-grey colour and perfect cubic cleavage, closely resemble galena in appearance; these species are named after the localities at which they were originally found, namely, Klausthal in the Harz and the Altai mountains in Asiatic Russia.

There was a pack of cigarettes and matches in her cleavage.

In some cases all the eggs in a capsule develop; in other cases one egg only in a capsule (Neritina), or a small proportion (Purpura, Buccinum), advance in development; the rest are arrested either after the first process of cell-division (cleavage) or before that process.

The mineral has a very perfect cleavage parallel to the faces c and m, and the cleavage surfaces are perfectly smooth and bright.

The crusaders of northern Germany never went to the Holy Land at all; they were allowed the crusaders' privileges for attacking the Wends to the east of the Elbe - a fact which at once attests the cleavage between northern and southern Germany (intensified of late years by the war of investitures), and anticipates the age of the Teutonic knights and their long Crusade on the Baltic. The crusaders of the Low Countries and of England took the sea route, and attacked and captured Lisbon on their way, thus helping to found the kingdom of Portugal, and achieving the one real success which was gained by the Second Crusade.

The deepest line of cleavage is naturally between the view that episcopacy is a divinely ordained institution essential to the effective existence of a church as a channel of grace, and the view that it is merely a convenient form of church order, evolved as the result of a variety of historical causes, and not necessary to the proper constitution of a church.

In so doing he points out that we become conscious of a great cleavage which practically divides the book into two parts, i.

Slates properly so-called do not, except on rare occasions, split along the bedding, but along planes of cleavage, which intersect the bedding usually at high angles.

The original material was a fine clay, sometimes with more or less of sand or ashy ingredients, occasionally with some lime; and the bedding may be indicated by alternating bands of different lithological character, crossing the cleavage faces of the slates, and often interrupting the cleavage, or rendering it imperfect.

Cleavage is thus a superinduced structure, and its explanation is to be found in the rearrangement of the minerals, and the development of a certain degree of crystallization by pressure acting on the rock.

Grits, igneous rocks, ashbeds and limestones may and often do show cleavage.

Slates consist largely of thin plates of mica arranged parallel to the cleavage faces.

It is produced by minute crumplings on the cleavage faces all arranged so that they lie along definite planes crossing the cleavage.

The finer varieties are made into writing slates, and in districts where cross cleavage exists slate pencils are made.

There is a perfect cleavage parallel to the surface of the scales, and the cleavage flakes are flexible but not elastic. The material is greasy to the touch, and soils everything with which it comes into contact.

An important character, and one by which the mineral may always be recognized, is the perfect cubical cleavage, on which the lustre is brilliant and metallic. The colour of the mineral and of its streak is lead-grey; it is opaque; the hardness is 2 2 and the specific gravity 7.5.

Blouses that reveal a lot of cleavage are appropriate for evening wear, but should not be worn at the office.

Want to show off your shoulders and cleavage?

Opt for tops that accentuate your cleavage.

They had almost finished their drinks when the pretty bartender leaned over, a little closer than necessary, displaying her ample cleavage.

All these are strikingly alike in appearance and general characters, differing essentially only in chemical composition, and it would seem better to reserve the name cerargyrite for the whole group, using the names chlorargyrite (AgC1), embolite (Ag(Cl, Bl)), bromargyrite (AgBr) and iodembolite (Ag(C1, Br, I)) for the different isomorphous members of the group. They are cubic in crystallization, with the cube and the octahedron as prominent forms, but crystals are small and usually indistinct; there is no cleavage.

The cleavage of these factions was at first purely personal; but by 1832 it had become one of principle.

A main cause of the cleavage in Germany was the position of ecclesiastical affairs, which - though by no means hopeless - yet stood in urgent need of emendation, and, combined with this, the deeply resented financial system of the Curia.

In 1854, after the meeting of the British Association in Liverpool, a memorable visit occurred to the Penrhyn slate quarries, where the question of slaty cleavage arose in his mind, and ultimately led him, with Huxley, to Switzerland to study the phenomena of glaciers.

Pyrites presents a conchoidal fracture, and a very indistinct cubic cleavage.

This proposal caused a cleavage right through P P g g g all parties.

Bort (or Boart) is the name given to impure crystals or fragments useless for jewels; it is also applied to the rounded crystalline aggregates, which generally have a grey colour, a rough surface, often a radial structure, and are devoid of good cleavage.

Carbonado or " black diamond," found in Bahia (also recently in Minas Geraes), is a black material with a minutely crystalline structure somewhat porous, opaque, resembling charcoal in appearance, devoid of cleavage, rather harder than diamond, but of less specific gravity; it sometimes displays a rude cubic crystalline form.

Rock drilling is the most important industrial application; and for this, owing to its freedom from cleavage, the carbonado is more highly prized than diamond; it is broken into fragments about 3 carats in weight; and in 1905 the value of carbonado was no less than from £10 to £14 a carat.

This extraordinary diamond weighed 30254 carats (13 lb) and was clear and water white; the largest of its surfaces appeared to be a cleavage plane, so that it might be only a portion of a much larger stone.

An important character of blende is the perfect dodecahedral cleavage, there being six directions of cleavage parallel to the faces of the rhombic dodecahedron, and angles between which are 600.

For this reason the mineral is not always readily recognized by inspection, though the perfect dodecahedral cleavage, the adamantine lustre, and the brown streak are characters which may be relied upon.

In addition to the political strife and anxiety due to this fundamental cleavage within the nation, Germany was troubled during the first decade of the 20th century by friction and jealousies arising out of the federal constitution Prussia of the Empire and the preponderant place in it of Prussia.

The blocks were quarried by cleavage; a groove was run along the line intended, and about 2 ft.

The mineral has perfect cubic cleavage.

Its appearance has been associated with the invasion of the Israelites or with the establishment of the independent monarchy, but on very inadequate grounds; and since it has been independently placed at the latter part of the monarchy, its historical explanation may presumably be found in that break in the career of Palestine when peoples were changed and new organizations slowly grew up. 5 The great significance of these vicissitudes for the course of internal conditions in Palestine is evident when it is observed that the subsequent cleavage between Judah and Samaria, not earlier than the 5th century, presupposes an antecedent common foundation which, in view of the history of the monarchies, can hardly be earlier than the 7th century.

It seems to follow that the cleavage between knowledge and reality 12 Topics, Iola 25, 36-37, bi-4, &c.

Theophrastus and in general the elder Peripatetics, before the rise of new schools with new lines of cleavage and new interests had led to new antagonisms and new alliances, do not break away from the Aristotelian The Peri= metaphysic. Their interests, however, lie in the sublunary patetics.
