The two nerve-rings are connected by fibres passing from one to the other.

The natural products include fine cabinet and construction woods, rubber, fruit, palm oil and fibres.

Below this is a circular, and below that again a longitudinal, layer of muscle fibres.

The muscular layers are thinner in the aquatic forms, which possess only a single row of longitudinal fibres, or (Enchytraeidae) two layers.

This may be associated with mud-eating habits; but it is not wholly certain that this is the case; for in Chaetogaster and Agriodrilus, which are predaceous worms, there is no protrusible pharynx, though in the latter the oesophagus is thickened through its extent with muscular fibres.

Having arrived at the conclusion that the food of plants consists of minute particles of earth taken up by their rootlets, it followed that the more thoroughly the soil in which they grew was disintegrated, the more abundant would be the " pasture " (as he called it) to which their fibres would have access.

It is clear that, if we start from the condition of full eversion of the tube and watch the process of introversion, we shall find that the pleurecbolic variety is introverted by the apex of the tube sinking inwards; it may be called acrembolic, whilst conversely the acrecbolic tubes are pleurembolic. Further, it is obvious enough that the process either of introversion or of eversion of the tube may be arrested at any point, by the development of fibres connecting the wall of the introverted tube with the wall of the body, or with an axial structure such as the oesophagus; on the other hand, the range of movement of the tubular introvert may be unlimited or complete.

Fibres and vegetable grasses, wool, hides and skins, cotton, sugar, iron and steel and their manufactures, chemicals, coal, and leather and its manufactures are the leading imports; provisions, leather and its manufactures, cotton and its manufactures, breadstuffs, iron and steel and.

This characteristic is of great economic importance, the natural twist facilitating the operation of spinning the fibres into thread or yarn.

The proboscis, which is thus an eminently muscular organ, is composed of two or three, sometimes powerful, layers of muscles - one of longitudinal and one or two of circular fibres.

In the posterior retractor the longitudinal fibres become united into one bundle, which, as noticed above, is inserted in the wall of the sheath.

At the circular insertion of the proboscis in front of the brain the muscular fibres belonging to the anterior extremity of the body and those connected with the proboscis are very intimately interwoven, forming a strong attachment.

Increase in size appears sometimes to be accompanied by the development of a new layer of fibres, whereas a difference in the method of preparation may give to a layer which appeared homogeneous in one specimen a decidedly fibrous aspect in another.

The Heteronemertini thus appear to have developed an extra layer of longitudinal fibres internally to those which they inherited from more primitive ancestors, whereas the Metanemertini are no longer in possession of the internal circular layer, but have on the contrary largely developed the external circular one, which has dwindled away in the Heteronemertini.

In addition to the musculature of the proboscis and proboscidian sheath, longitudinal muscular fibres are found in the walls of the oesophagus, whilst transverse ones are numerous and united into vertical dissepiments between the successive intestinal caeca, thus bringing about a very regular internal metamerization.

The oesophagus is the anterior portion of the digestive canal; its walls are folded longitudinally, comparatively thick and provided with longitudinal muscular fibres.

This second coil is suspended by a number of silk fibres, and to the coil is also attached a spiral spring the other end of which is fastened to a torsion head.

This property is usually obtained by mixing soft and hard soaps, or, more rarely, by adding gum tragacanth to a hard soap. In the textile trades the wool scourer employs a neutral olive-oil soap, or, on account of its cheapness, a neutral curd or curd mottled brand; the cotton cleanser, on the other hand, uses an alkaline soap, but for cleaning printed cottons a neutral olive-oil curd soap is used, for, in this case, free alkali and resin are objectionable; olive-oil soap, free from caustic alkali, but often with sodium carbonate, is also used in cleansing silk fibres, although hard soaps free from resin are frequently employed for their cheapness.

A clear distinction must be drawn between colour and the property of dyeing; all coloured substances are not dyes, and it is shown in the article Dyeing that the property of entering into chemical or physical combination with fibres involves properties other than those essential to colour.

Inside the syncytium is a not very regular layer of circular muscle fibres, and within this again some rather scattered longitudinal fibres; there is no endothelium.

In their minute structure the muscular fibres resemble those of Nematodes.

Except for the absence of 'the longitudinal fibres the skin of the proboscis resembles that of the body, but the fluid-containing tubules of the latter are shut off from those of the body.

It results from this that the horn has the appearance of a mass of agglutinated hairs, which, in the newly growing part at the base, readily fray out on destruction of the softer intermediate substance; but the fibres differ from true hairs in growing from a free papilla of the derm, and not within a follicular involution of the same.

The nervous system is thus essentially epidermal in position and diffuse in distribution; but an interesting concentration of nerve-cells and fibres has taken place in the collar-region, where a medullary tube, closed in from the outside, opens in front and behind by anterior and posterior neuropores.

These hollow roots terminate blindly in the dorsal epidermis of the collar, and place the nervous layer of the latter in direct connexion with the fibres of the nerve-tube.

From the ventral surface of the collar nerve-tube numerous motor fibres may be seen passing to the subjacent musculature.

These fibres are not aggregated into roots.

The flowers are yellow, and the seeds enclosed in a pod are long and thin with numerous long silky fibres attached to them, which enable the seeds to be readily carried by the wind.

Others of the endothelial cells show a great tendency to form muscle fibres.

Much of the latter takes the form of hyaline supporting tissue, embedded in which are scattered cells and fibres.

The action of aconitine on the circulation is due to an initial stimulation of the cardio-inhibitory centre in the medulla oblongata (at the root of the vagus nerves), and later to a directly toxic influence on the nerve-ganglia and muscular fibres of the heart itself.

But they also receive the nerve fibres of the optic nerve.

Muscular fibres connected with the suctorial pharynx are in Limulus inserted into the entosternite, and the activity of the two organs may be correlated.

The Scyths had a method of divination with sticks, and the Enarees, who claimed to be soothsayers by grant of the goddess who had afflicted them, used another method by splitting bast fibres.

The forest products, whose collection and preparation form regular industries, are rubber (called Gaucho or goma), tonka beans, vanilla, copaiba, chique-chique, sarsaparilla, divi-divi, dye-woods, cabinet-woods and fibres.

Increased work thrown on to a tissue may produce hypertrophy, but, if this excessive function be kept up, atrophy will follow; even the blacksmith's arm breaks down owing to the hypertrophic muscle fibres becoming markedly atrophied.

Many of the muscle fibres show numerous droplets of oil seen as dark round granules.

Note that the malignant cells are invading and destroying the muscle fibres of the heart.

The fibres are arranged in irregular bundles forming a dense firm tissue.

The change appears to begin in the fibrils which lie between the circular muscle fibres of the middle coat of the smaller arterioles and extends both backwards and forwards along the vessels.

It spreads forwards, affecting the supporting fibres outside the epithelium of the capillaries, and then passes to the connective-tissue fibrils of the veins.

Other crops which are grown in the province, especially in Upper Burma, comprise maize, tilseed, sugar-cane, cotton, tobacco, wheat, millet, other food grains including pulse, condiments and spices, tea, barley, sago, linseed and other oil-seeds, various fibres, indigo and other dye crops, besides orchards and garden produce.

Almost all the Guanches used to wear garments of goat-skins, and others of vegetable fibres, which have been found in the tombs of Grand Canary.

The muscles are composed of outer circular and inner longitudinal layers, and of branched dorso-ventral fibres.

The natural products of Peru include rubber, cabinet woods in great variety, cinchona or Peruvian bark and other medicinal products, various fibres, and guano.

This layer also forms the attachment for the muscles, of which there are two enveloping coats, a circular and a longitudinal layer and also dorso-ventral fibres.

The gathering and preparation of "ixtle" fibres from the agave and yucca forms another important industry, the fibre being sent to Tampico for export.

Soc., 1880, 30, p. 411, showing experiments on residual charge of condensers and a comparison between the behaviour of dielectrics and glass fibres under torsion.

Pulses of different sorts, oilseeds, fibres, sugar-cane, tobacco, spices and vegetables also form crops of the district.

This species usually constructs its nest on the bottom, excavating a hollow in which a bed of grass, rootlets or fibres is prepared; walls are then raised, and the whole is roofed over with the like material.
