Metamorphosis.It has already been pointed out that each kind of member of the body may present a variety of forms. For example, a stem may be a tree-trunk, or a twining stem, or a tendril, or a thorn, or a creeping rhizome, or a tuber; a leaf may be a green foliage-leaf, or a scale protecting a bud, or a tendril, or a pitcher, or a floral leaf, either sepal, petal, stamen or carpel (sporophyll); a root may be a fibrous root, or a swollen tap-root like that of the beet or the turnip. All these various forms are organs discharging some special function, and are examples of what Wolff called modification, and Goethe metamorphosis.

G, The acrecbolic snout of a proboscidiferous Gastropod, arrested short of complete eversion by the fibrous band b.
The platy minerals have also a perfect cleavage parallel to their flat surfaces, while the fibrous species often have two or more cleavages following their long axes; hence a schistose rock may split not only by separation of the mineral plates from one another but also by cleavage of the parallel minerals through their substance.
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.
As central organs we have to note the brain-lobes and the longitudinal lateral cords which form one continuous unsegmented mass of fibrous and cellular nerve-tissue.
The fibrous nervetissue is more dense in the higher differentiated, more loose and spongy in the lower organized 1P L forms; the cellular nerve-tissue is FIG.

Another type of incipient crystallization which is excessively common in obsidian is spherulites, or small rounded bodies which have a radiating fibrous structure.
The entosternite was probably in origin part of the fibrous connective tissue lying close to the integument of the sternal surface - giving attachment to muscles corresponding more or less to those at present attached to it.
Its walls are fibrous and complete, and it holds a considerable volume of blood when the heart itself is contracted.
Its favourite situation is the outlet (pyloric cancer), where a hard, fibrous growth forms a contracting ring of the scirrhous variety.
Another characteristic of cancer is that it spreads far and wide, drawing other tissues to itself by contracting fibrous bands.
Simple fibrous narrowing of the gateway of the stomach or of the intestine is dealt with by dividing it longitudinally and then suturing the edges of the wound transversely.
10 1 60 in.), but also those of fibrous material, for which the theory is analogous.
Muscle and white fibrous tissue follow next in order, while elastic tissue and bone are the last to show signs of disintegration.
Then they develop .definite fibrils which differentiate into fibrous laminae forming a zone which shuts off the abscess from the healthy tissue and so prevents the further invasion and injurious effects of the microorganism.
III.), which in turn has to give way to the more firm and differentiated fibrous tissue.
At a period corresponding to the condensation of the fibrous laminae and the disappearance of the cellular character of the granulation tissue.
Where a chronic inflammatory process has taken possession of an organ, or, let us say, has been located in periosteum or other fibrous part, there is a great tendency to the production of cicatricial fibrous tissue in mass.
IV.), that of " sclerosis " is used when such a deposition of fibrous tissue occurs within the central nervous system.
They supposed that it was accompanied by a peculiar hyaline thickening of the arterial wall, usually of the tunica intima, and hence they termed the supposed diseased state " arterio-capillary fibrosis," and gave the fibrous substance the name " hyaline-fibroid."
They held that the cirrhotic kidney is simply a local manifestation of a general fibrous disease.
Syphilitic lesion of the arteries, and likewise of other fibrous tissues, often involves grave consequential damage to nervous structures fed or supported by such parts.
It fuses at 339° to a colourless liquid, which solidifies on cooling to a white fibrous mass, known in pharmacy as sal prunelia.
The root occurs in fibrous pieces, which are usually rectangular blocks of irregular shape, 2 in.
Into the ground and the whole frameworkconsisting of posts, beams, rafters, door-posts and window-frames was tied together with cords made by twisting the long fibrous stems of climbing plants.
Freezing takes place by the formation of pure ice in flat crystalline plates of the hexagonal system, which form in perpendicular planes and unite in bundles to form grains so that a thick covering of ice exhibits a fibrous structure.
Coal is never definitely crystalline, the nearest approach to such a structure being a compound fibrous grouping resembling that of gypsum or arragonite, which occurs in some of the steam coals of South Wales, and is locally known as " cone in cone," but no definite form or arrangement can be made out of the fibres.
For separating liquids from solids of a fibrous or crystalline character "hydroextractors" or "centrifugals" are frequently employed.
Marcasite readily oxidizes on exposure to moist air, with the production of sulphuric acid and a white fibrous efflorescence of ferrous sulphate, and in course of time specimens in collections often became completely disintegrated.
If absorption be not complete the mass undergoes caseation and becomes surrounded by a capsule of fibrous tissue - being sharply cut off from the healthy tissue.
The rocks in the Arakan range and its spurs are metamorphic, and comprise clay, slates, ironstone and indurated sandstone; towards the S., ironstone, trap and rocks of basaltic character are common; veins of steatite and white fibrous quartz are also found.

The body-cavity and the muscular, fibrous and vascular tissues are traced partly to two symmetrically disposed " mesoblasts," which bud off from the invaginated arch-enteron, partly to cells derived from the ectoderm, which at a very early stage is connected by long processes with the invaginated endoderm.
It has small leaves and fibrous bark, the wood is light, soft and easily-worked, and very durable in contact with the soil, and is much used for boat-building and for making fences and coopers' staves.
