“ Closely allied to the areolar is the fibrous tissue, in which the white fibers lie close together and run for the most part in one direction only. This is found in ligaments, joints and tendons, as also in such fibrous protective membranes as the periosteum, dura mater, the fasciæ of muscles, etc. Fibrous tissue is silvery white in appearance and is very strong and tough, yet pliant. ”

“ The fibrillae are united to one another by interfibrillar substance to form bundles, of which there may be a considerable number in each muscle fibre. The bundles lie in a surrounding layer of sarcoplasm which apparently represents the remaining portion of unaltered protoplasm of the syncytium. This structure of muscle is best seen in the transverse sections of the fibres. A number of areas separated by a clear protoplasm are then to be seen. The areas are formed by the bundles of fibrillae seen in transverse section, the intermediate substance is the sarcoplasm. ”

“ The fibre is decidedly inferior to flax and hemp in strength and tenacity; and, owing to a peculiarity in its microscopic structure, by which the walls of the separate cells composing the fibre vary much in thickness at different points, the single strands of fibre are of unequal strength. Recently prepared fibre is always stronger, more lustrous, softer and whiter than such as has been stored for some time—age and exposure rendering it brown in colour and harsh and brittle in quality. ”

“ Small nerve trunk containing two naked fibrils in sheath. Aniline blue. Fig. 9. Single naked nerve fibril found passing on to an alveolus. It seemed to pass on to the capillary figured but a small break, where the fibre might have been torn, or where from the underlying cells it could not be distinguished—allows doubt if the fibre seen along-side of the capillary is the continuation of the fibre. Carmine and aniline blue. Figs. 10 and 11. Capillaries with nerve fibrils accompanying the same. Carmine and aniline blue. ”

“ The first is encountered when death has ensued after a long stage of sickness. The vital fluids become exhausted by disease, and the organs of circulation become too weak to perform their office of circulating the fluid they contain; hence, dissolution takes place in the blood from want of constant and rapid action. Thus the fibrine becomes lodged and coagulated in the veins and capillary system. The fibrine and serum separate, leaving the fibrine coagulated or clotted, and the serum, a transparent, fatty or oily liquid, permeates the tissues of the flesh. ”

“ The Sisal hemp machines are too rough in action for so fine a fiber, and, at the rate of ten leaves to the pound, working up a ton of the material would mean the handling of over twenty thousand leaves to secure perhaps three dollars' worth of the commercial product. Were the fiber utilized in the arts, however, and its place established, it would compete in a measure with flax as a spinning fiber, for its filaments are divisible to the ten-thousandth of an inch. ”

“ Large portions of loosely coagulated blood were found in all the cavities; some of these clots were of a rusty colour, others approached nearer to the natural colour of the blood. The lung was compressed against the spine, and the whole surface of the pleural sac was coated by a false membrane, about two lines in thickness, formed by coagulated fibrine. The fibrine which lined the pleura pulmonalis and pleura diaphragmatica, presented on its inner surface a smooth and polished appearance, and in colour exactly resembled the yellowish fibrine found in the clots of the heart of this patient. ”

“ The fibrous substance is as the base of the organ. We distinguish this base very plainly in the fibro-cartilages of the tendinous grooves and of the articulations, in those especially of the body of the vertebræ; it is much less apparent in the membranous fibro-cartilages. Its fibres are sometimes interlaced, sometimes parallel. In general its nature is exactly the same as in the fibrous system, hard, resisting, dense and compact, hence the very great force which the organs of this system have ”

“ Each of these fibrils consists of a number of cells pressed closely together and having a peculiar bearded appearance (figs. 77, 78) . It is by the sudden approximation and flattening of these cells that the muscle is shortened during contraction, but the contraction of each fibril is only for an instant, and then a relaxation and elongation of the cells takes place, which is followed by a second contraction, and so on. ”

“ As a rule, the fibril cannot so readily be detected, but the nuclei belonging to it are not difficult to recognize. A still more convenient and instructive locality is the base of the frog’s mouth, where everything is one plane, and where the nerve fibres can be followed to their ultimate ramifications.
Let us now see what evidence of nerve-endings we find in or on the alveoli of the gland, examining one, or more accurately, a part of one (the round eminence) . We shall see what fig. 1 201presents. We see there two sets of nuclei ”

“ On the contraction of the fibre a part of the spirit of animation becomes expended, and the fibre ceases to contract, though the stimulus continues to be applied; till in a certain time the fibre having received a supply of sensorial power is ready to contract again, if the stimulus continues to be applied. If the stimulus on the contrary be withdrawn, the same quantity of quiescent sensorial power becomes resident in the fibre as before its contraction; as appears from the readiness for action of the large locomotive muscles of the body in a short time after common exertion. ”

“ In some of the vegetable bodies burned in this manner, in addition to the simple molecules, primary combinations of these were observed, consisting of fibrils having transverse contractions, corresponding in number, as I conjectured, with that of the molecules composing them; and those fibrils, when not consisting of a greater number than four or five molecules, exhibited motion resembling in kind and vivacity that of the mineral fibrils already described, while longer fibrils of the same apparent diameter were at rest. ”

“ At the time when Boerhaave made use of the term “fibre” (fibra) in the very uncertain sense in which he here employs it, Leeuwenhoek and Malpighi were demonstrating, by aid of the newly perfected microscope, that the so-called simple tissues were in reality quite complex structures; and one’s first impulse, therefore, is to express surprise that a physician of such high standing as our author should have used the term. ”

“ Thus each muscular fibre may be regarded as composed of larger and smaller bundles of fibrils imbedded in a nucleated protoplasmic framework which ensheaths the whole and is itself invested by the sarcolemma.
As the fibre dies, the nuclei acquire hard, dark contours and their contents become granular, while at the same time the fibrils acquire sharp and well-defined boundaries. In fact, the fibre may now be readily teased out with needles, and the fibrils isolated. ”

“ In the muscles the fibrine is arranged in a truly organized and living condition, constituting the contractile fibres, in which it is so interwoven with nervous and vascular filaments as to render its isolation impossible. ”

“ The white matter is every where fibrous. No person has contributed more than Gall to the demonstration of this great fact. He justly remarks: “Those authors who, with Sœmmerring and Cuvier, &c., recognise the fibrous structure of the brain, in many of its parts, have nevertheless, not yet ventured to say that it is so in all its parts.”—T. i. ”

“ If the blow be given in the direction of the fibre, resistance to entrance of the edge is much less than in the blow across that fibre. So great, indeed, may this difference become, that while the axe in Class 1 seems in all respects a suitable tool, yet as the attention of the workman passes to directions inclined to the fibre at an angle of more than forty-five degrees, he will be induced to lay aside the tools in Class 1, and try those in Class 2 ”

“ Fibrin is that substance in blood which causes it to coagulate when shed. It consists of innumerable delicate fibrils which entangle the blood corpuscles, and form with them a mass called blood clot. Fibrin is insoluble in both cold and hot water. ”

“ Other Fibers While the fibers we have already discussed—Manila and Sisal—comprise by far the greater part of the raw material of cordage, we wish to mention in this chapter a fiber which, while now of comparatively slight importance, has the interesting feature of being a home product, and the cultivation of which at one time formed an industry of considerable magnitude in this country. ”

“ In general appearance the fibre is similar to linen, with slightly thinner walls, more markings, and at the places where joint markings occur are also little hairs. The ends of the fibres are rounded or flattened. The fibre in paper is usually beaten so finely as not to be recognised (Fig. 19) . ”

“ Both continuous and staple fibers can be made from basalt. Continuous fibers are produced using standard glass fiber production equipment. After the feedstock is fused in an electric furnace, the melt is fed to electrically heated platinum.rhodium bushings containing 200-300 perforations. As shown in figure 4.7 (Subramanian et al., 1975) , a drum winding pulls the fibers from the platinum.rhodium bushing perforations. Fiber diameter is a function of melt temperature and drum or centrifugal nozzle speed. ”

“ Since the tool, as now contrived, cannot efficiently cross-cut the resisting fibre, and since that fibre has to be removed, the object must be either to prevent such an accumulation of fibres as will stop the progress of the tool, or to destroy the fibre piecemeal as it is operative for hinderance. ”

“ There is no upper limit on the fiber diameter in the counting rules. Note that fiber width is measured at the widest compact section of the object. 1 fiber Although long fine fibrils may extend from the body of a fiber, these fibrils are considered part of the fiber if they seem to have originally been part of the bundle. Do not count If the object is ≤ 5 μm long, it is not counted. 1 fiber A fiber partially obscured by a particle is counted as one fiber. ”

“ The four smaller circles and that in the centre are ornamented with bosses of a white substance, either ivory or bone, but the material is so much decomposed it is difficult to say which; these bosses are attached to the copper plate beneath by iron pins. The entire face of the fibula was originally set with small pieces of garnet-coloured glass laid upon hatched gold-foil. The upper and lower plates of this ornament are bound together by a band of copper gilt, slightly grooved. The acus is lost.

“ Each fibre has a broad lumen and is very similar to hemp fibre. Examination of all these fibres, by the way, is best made in water as described under cotton.
Hemp is another bast fibre and as we have remarked it resembles the short fibres of flax; there is a broad lumen with an indistinct margin. ”

“ It allows the disused fibula to retain a [148] potentiality of development fully equal to that possessed by the long-used tibia. It lengthens legs because they are used in supporting the body, and shortens arms because they are used in pulling. Whether it enlarges brain if used in one way and diminishes it if used in another, we cannot tell ”

“ Growl he would, from the moment the petting began till it ended. But it was a growl with a new note in it. A stranger could not hear this note, and to such a stranger the growling of White Fang was an exhibition of primordial savagery, nerve-racking and blood-curdling. But White Fang’s throat had become harsh-fibred from the making of ferocious sounds through the many years since his first little rasp of anger in the lair of his cubhood, and he could not soften the sounds of that throat now to express the gentleness he felt. ”

“ To feel its wondrous harmonies searching the subtlest windings of your soul, the delicate fibres of life where no memory can penetrate, and binding together your whole being past and present in one unspeakable vibration, melting you in one moment with all the tenderness, all the love that has been scattered through the toilsome years, concentrating in one emotion of heroic courage or resignation all the hard-learnt lessons of self-renouncing sympathy, blending your present joy with past sorrow and your present sorrow with all your past joy? ”

“ What novelty is worth that sweet monotony where everything is known, and loved because it is known?
The wood I walk in on this mild May day, with the young yellow-brown foliage of the oaks between me and the blue sky, the white star-flowers and the blue-eyed speedwell and the ground ivy at my feet, what grove of tropic palms, what strange ferns or splendid broad-petalled blossoms, could ever thrill such deep and delicate fibres within me as this home scene? ”

“ Then the child’s cry changed to impatience, to terror and at last to despair. It was Fifi. The mother was dead, but the child did not know it then. She had no one in the world that I could discover; so, when I was started for France in a cart—for I could not walk at all then—I brought Fifi with me. She was so light, her weight made no difference, and ate so little that she could live off my rations and there would still be enough left for me. When we got to Paris, I hired a little garret for her, in yonder tall old house where I live, and Fifi lives there still. ”
