Granulation

“ It is often increased by boils, which follow one another in rapid succession, and which sometimes may be counted by scores. Besides the wet cloth, the usual remedy to cause granulation, and to prevent the sore leaving a head, is to stuff it with camphor and Peruvian bark. ”

“ Granulated honey.—Some honeys, such as alfalfa, granulate quickly after being extracted. Such honeys are sometimes allowed to granulate in large cans and the semisolid mass is then cut into 1-pound bricks like a butter print and wrapped in paraffin paper. It may be put into paraffined receptacles before granulation, if desired. There is always a ready market for granulated honey, since many people prefer it to the liquid honey. ”

“ Granulation Tissue.#--The essential and invariable medium of repair in all structures is an elementary form of new tissue known as _granulation tissue_, which is produced in the damaged area in response to the irritation caused by injury or disease. The vital reaction induced by such irritation results in dilatation of the vessels of the part, emigration of leucocytes, transudation of lymph, and certain proliferative changes in the fixed tissue cells. These changes are common to the processes of inflammation and repair ”

“ Any wound that suppurates much or sloughs causes a cavity to be filled up, and the process by which the wounds and sores heal is called granulation, and cicitrization. The wound is gradually filled up to the surrounding level by new tissue appearing in the form of small red granules bathed in pus. Healthy granulations on an exposed or flat surface rise nearly even with the surrounding skin, and often a little higher, but when they are much higher, and take on a growing action, they are what is called proud flesh. Their growth may be checked by the application of active astringents ”

“ Gentle pressure, accompanied with the use of cold water, is of service in the same cases in which poultices are employed; that is to say, when the action has not become perfect, but has rather begun to subside, and the granulations remain dark coloured, and in a dying state. They are absorbed, and replaced with more perfect and healthy granulations. ”

“ Here the clean metallic surface presents no recesses like those of porous lint for the septic germs to develope in, the fluid exuding from the surface of the granulations has flowed away undecomposed, and the result is the absence of suppuration. This simple experiment illustrates the important fact that granulations have no inherent tendency to form pus, but do so only when subjected to preternatural stimulus. Further, it shows that the mere contact of a foreign body does not of itself stimulate granulations to suppurate; whereas the presence of decomposing organic matter does. ”

“ Gran′ūlāte, to form or break into grains or small masses: to make rough on the surface.—v.i. to be formed into grains.—adj. granular: having the surface covered with small elevations.—n. Granūlā′tion, act of forming into grains, esp. of metals by pouring them through a sieve into water while hot: (pl.) the materials of new texture as first formed in a wound or on an ulcerated surface.—adjs. Granūlif′erous; Gran′ūliform.—n. Gran′ūlīte, a schistose but sometimes massive aggregate of quartz and orthoclase with garnets. [L. granulum, dim. of granum, grain.] ”

“ Again, if I applied far more manure than was necessary, I ought to have had the crop equally good throughout the field; but on the ridge of the hill, where the soil was thin and poor, neither straw nor wheat were so good as they were where it was deeper and richer. My own opinion is, that the plant is never able to extract from the soil all the manure, and therefore it ought to be brought up to a good standard before good crops can be expected. I am not satisfied with any analogy that I can think of, but the best that occurs to me is that of a cloth in a dye- copper. ”

“ Recurring again to the quantity of manure necessary to grow thirty-six bushels of wheat, I would ask, why limit yourself to so small a crop? The difference in the cost of your manuring a field, and my manuring it, is more than made up by the increase of fourteen bushels of wheat and the corresponding increase of straw, even if the land did not improve every year by the application; and as the seed, rent, labour, and liabilities of the land are the same whether you grow a small crop or a large one, why not have it as large as possible? ”

“ The volume of the transparent involucra is disproportionate to the embryo itself: yet the placental covering, with its filiform vessels, bears a still larger proportion to them; so that the want of equilibrium between the external and internal apparatus of the Ovum has destroyed, first the growth, and next the life of the embryo. The preparation is in the museum of St. George’s Hospital, and like the preceding preparation (5) , has been flattened and pinned to a pasteboard—a mode which, for the steady display of the peculiarities of the Ovum in both cases, was, perhaps, the most judicious. ”

“ It has been objected to these experiments, that allowing all to have been done which is here detailed, it leads to no important conclusion; for although it may be practicable to grow wheat every year, in a small field like the one experimented on, it is not so on a large scale. But the objectors should remember that there is not the seed of a single weed sowed with the manure; and therefore if the land is thoroughly cleaned, and kept so, by hoeing the crop in the spring, it will require very little labour to fit it for another. ”

“ Common Source of Losses.—When we bear in mind that four fifths of all the fertility removed from the land in the grains and coarse stuffs fed on the farm may be recovered from the animals and returned to the soil, we can appreciate the consideration that the care of manure should have on every farm. The careless methods that prevail in most sections of the country are an inheritance from the day when soils were new and full of fertility. ”

“ Supposing the states I have described to exist, I venture to suggest that the development of a new crop of cells from denuded germs or nuclei will account for the facility with which reeducation, in cases like that described by Professor Sharpey, reproduces knowledge, even at a period of life when it is not easy to learn. What the new training and teaching does is not so much to impart information as to foster the growth of a new crop from the old seed, just as an after-crop may be procured by breaking up an overstocked soil and applying the stimulus of manure. ”

“ This change, of course, gives us a series, as in the case of alum above mentioned.
Fig. 470.—Garnet crystal.
The red varieties, called almandine, or precious garnets, are distinguished from the duller, “common” species by their clear colour. Bohemia is the most productive soil for the garnets.
Mica includes, as we have already noticed, a group of minerals which have a peculiarly laminated structure. These layers are by no means all alike, but they present a smoothness to the fingers which is highly characteristic. The chief constituents are alumina and silica, occasionally with magnesia. ”

“ I want to have a garden and orchard rise up and meet me every morning, with the request to "lay on, Macduff." I respect old age; but an old currant- bush, hoary with mossy bark, is a melancholy spectacle.
I suppose the time has come when I am expected to say something about fertilizers: all agriculturists do. When you plant, you think you cannot fertilize too much: when you get the bills for the manure, you think you cannot fertilize too little. Of course you do not expect to get the value of the manure back in fruits and vegetables ”

“ When one sows his field with one kind, Even though he makes two granaries,he gives one corner. If he sows two species, even though he makes one granary, He gives two corners. If he sows his field with two species of wheat, And makes one granary,he gives one corner, But if two granaries, two corners. ”

“ Too much manure renders some kinds utterly sterile, as I have myself observed. The tendency to sterility from this cause runs in families; thus, according to Gärtner, [76] it is hardly possible to give too much manure to most Gramineæ, Cruciferæ, and Leguminosæ, whilst succulent and bulbous-rooted plants are easily affected. Extreme poverty of soil is less apt to induce sterility; but dwarfed plants of Trifolium minus and repens, growing on a lawn often mown and never manured, did not produce any seed. ”

“ In employing ebullition, we have the advantage of preparing the bones more promptly, and in a manner less insalubrious than by maceration. Nevertheless, this mode of preparation has its inconvenience: 1. Bones which are boiled, become, in general, less white than those which are macerated; the blood coagulating in their pores, leaves a brown tinge, which it is often impossible to remove; 2. They commonly retain a greater quantity of medullary matter, which, by becoming rancid, soon gives them a yellow colour and a very disagreeable odour ”

“ His Sixth Lecture treats of manures of animal and vegetable origin, and of the general principles with respect to their uses and modes of application.
It is evident that plants, by their growth, must gradually exhaust the soil of its richer and more nutrient parts; and these can be alone restored by the application of manures. It is equally obvious, that if a soil be sterile from any defect in its constitution, such a defect can be only remedied by artificial additions. ”

“ The question, What constitutes fertility in a soil? is by no means an easy one to answer. If we say, The presence of a plentiful supply of the constituents which form the plant's food, our answer will be incomplete. Similarly, if we reply, A certain physical condition of the soil—here, again, it will be found equally unsatisfactory; for fertility of a soil depends both on its physical condition and on its chemical composition, and indeed even on other circumstances. ”

“ In one point of view, more especially, is the present diseased Ovum particularly interesting to me; for it exhibits the most distinct proof that what I call the cortex of the Ovum, and which others have, without direct evidence, considered as a membrane of the uterus, is, in good truth, a natural covering of the Ovum. It is this very natural covering of the Ovum which is liable, from disease, to become fleshy, opaque, vascular, and lastly coriaceous, thereby cutting short the supply, or accretion of substance to the fœtus, and thus destroying its life and producing abortion. ”

“ Influence of the granular sediments upon the tilling qualities of Soils.—Considering the granular sediments by themselves, in the absence of clay, it may be stated in a general way that while in a moist condition they flocculate sufficiently to produce a fair tilth, they will nevertheless on drying collapse into a close arrangement resulting from the single-grain structure. The form of the grains being angular instead of rounded, they are apt to form a very closely packed mass far from suitable to vegetable growth ”

“ The graft should be surrounded with good stiff clay with a little horse or cow manure in it and a portion of cut hay. Mix the materials with a little water and then beat them up with a stick until the compound is quite ductile. When applied it may be bandaged with a cloth. The best season for grafting in India is the rains.
MANURE.--Almost any thing that rots quickly is a good manure. It is possible to manure too highly. A plant sometimes dies from too much richness of soil as well as from too barren a one. ”

“ The importance of the conditions, other than those of a purely chemical nature, have been thus far somewhat prominently emphasised, for the reason that in what follows attention will be almost exclusively devoted to the purely chemical conditions of fertility. It is well, then, to realise that, while the latter conditions are by far the most important, so far as the farmer is practically concerned, inasmuch as they are most under his control, they are not the only conditions, and are not by themselves able to control fertility. ”

“ The method of preservation ought to be preceded by some other operations, such as dissection, maceration, injection, ablution, corrosions, ligature of vessels, separation and distention of parts.
a. Dissection.—It consists in stripping the part which it is intended to preserve, of the tissues and organs which are foreign to it: if the object be the preparation of muscles, for example, these organs are left alone with their insertions in the bones, or rather, the vessels, previously injected, preserve their relations with the muscles and the bones. ”

“ As hinted in paragraph 28, some grainers expect to do too much with the overgraining. They try to correct a faulty ground work and to put in many details which properly belong to the graining proper. It is possible, of course, to help very much in the correction of many faults, especially in those of bettering the mottlings, but if the graining has not been laid out nor grained pretty near right, no amount of overgraining will make it right, and more work that would have been passable is rendered worthless by overdone overgraining than from any other one cause. ”

“ These experiments took place in the autumn of 1841, after the field had been cleared of a crop of oats, which was a very bad one; the land being not only naturally poor, but foul and exhausted by long cropping. As the season was very wet, it was indifferently cleaned, and one-fourth of it manured with a compost of night-soil and ashes, and then the field was sowed with wheat. ”
