Either (I) by the Mexican crusher or arrastra, in which the grinding is effected upon a bed of stone, over which heavy blocks of stone attached to cross arms are dragged by the rotation of the arms about a central spindle, or (2) by the Chilean mill or trapiche, also known as the edge-runner, where the grinding stones roll upon the floor, at the same time turning about a central upright - contrivances which are mainly used for the preparation of silver ores; but by far the largest proportion of the gold quartz of California, Australia and Africa is reduced by (3) the stamp mill, which is similar in principle to that used in Europe for the preparation of tin and other ores.
Hartog has endeavoured to show that it can only he formed by a dual force, analagous to that of magnetism, the spindle-fibi es being comparable to the lines of force in a magnetic field and possibly due to electrical differences in the cell.
The spindle arises partly from the cytoplasm, partly from the nucleus, or it may be derived entirely from the nucleusintranuclear spindleas occurs in many of the lower plants (Fungi, &c.).
As division proceeds, the filamentous nature of this cytoplasm becomes more prominent and the threads begin either to converge towards the poles of the nucleus, to form a bipolar spindle, or may converge towards, or radiate from, several different points, to form a multipolar spindle.
The formation of the spindle differs in details in different plants.

They are present from the beginning of the development of the cell-wail, and arise from the spindle fibres, all of which may be continued as connecting threads (endosperm of Tamus communis), or part of them may be overlaid by cellulose lamellae (endosperm of Lilium Martagon), or they may be all overlaid as in pollen mother-cells and pollen grains of Helleborus foetidus.

No spindle-whorls were found, but there were many varieties of cloth, platted and woven, bundles of yarn and balls of string.
There also might be seen the flat circular temalacatl or " spindle-stone," where captives armed with wooden weapons were allowed the mockery of a gladiatorial fight against well-armed champions.
These forms were elongated and spindle-like; and to one end of the body, near which the smaller nuclear element was situated, a well-developed flagellum was attached.
Two or three slubbing rovings are put up behind the machine opposite each spindle; each end is guided separately into back rollers and thence between smaller rollers, known as carrier rollers, to the front rollers.
The product is wound on to the bobbin by means of flyer and spindle, and is known as dandied or fine roving, and is then ready for the spinning frame.
The exigencies of competition prompted the discovery that if yarn were sold by weight fresh from the spindle its comparative dryness made such early sale less profitable than if it were allowed to "condition."

The limbs of the U are further twisted together in a looser or tighter coil, the axis of which may be traversed by a "spindle" muscle arising from the posterior end of the body.
Thread-Work.Stone spindle whorls (103) are common in the prehistoric age; wooden ones were usual, of a cylindrical form (104) ~n the XIIth, and conical (105) in the XVIIIth Dynasty.
He finds no spindle fibres or true chromosomes, and considers the division direct, not indirect.
The method once exclusively used consists in mixing the raw materials with a large quantity of water in a wash mill, a machine having radial horizontal arms driven from a central vertical spindle and carrying harrows which stir up and intermix any soft material placed in the pit in which the apparatus revolves.
Ermani), elder, poplar, elm, wild cherry (Prunus padus), Taxus baccata and several willows are mixed with the conifers; while farther south the maple, mountain ash and oak, as also the Japanese Panax ricinifolium, the Amur cork (Philodendron amurense), the spindle tree (Euonymus macropterus) and the vine (Vitis thunbergii) make their appearance.

It is in fact the electromagnet and spindle of a telegraph relay with a siphon in place of the tongue.
The cytoplasm is largely concerned in the formation of spindle fibres and centrosomes, and such structures as the cell membrane, cilia, or flagella, the coenocentrum, nematoplasl~ or vibrioids and physodes are also products of its activity.
They are more easily seen, when the nucleus is about to undergo mitosis, at the ends of the spindle, where they form the centres towards which the radiating fibres in.
At each pole of this spindle figure there often occur fibres radiating in all directions into the cytoplasm, and sometimes a minute granular body, the centrosome, is also found there.
(2) Metaphase.The chromosomes pass to the equator of the spindle and b,ecome attached to the spindle-fibres in such a way that they form a radiating starthaped figureAster-when seen from the pole of the spindle.
In Fucus and allied forms the spindle-fibres between the daughter nuclei disappear early and the new cell-wall is formed in the cytoplasm.
In length, actuating a universal joint on the first spindle of the register; it consisted of an air-tight thin metal tube with a coned fore-end, carrying flat metal vanes set at an angle.

Here the two elements, ovum and yolk-cells, are surrounded by a shell of operculate or of spindle-capped types.
This ring runs between friction wheels and is provided with teeth on its inner periphery, and these teeth transmit motion to a pinion on a spindle having at its other end another pinion which, through an intermediate wheel, rotates the heliometer tube.
The transmission spindle, just mentioned, carries at its end a head, 74, which, if turned directly, gives the second speed.

After the birth of a child, the tonalpouhqui or;sun-calculator drew its horoscope from the signs it was born under, and fixed the time for its solemn lustration or baptism, performed by the nurse with appropriate prayers to the gods, when a toy shield and bow were provided if it was a boy, or a toy spindle and distaff if it was a girl, and the child received its name.
Was of skins of woven aloe and palm fibre, but at the time of the conquest cotton was largely cultivated in the hot lands, spun with a spindle, and woven in a rudimentary loom without a shuttle into the mantles and breech-cloths of the men and the chemises and skirts of the women, garments often of fine texture and embroidered in colours.
