Bath is the immersion of the body in water, or an apparatus for this purpose. The use of the bath as an institution apart from occasional immersion in rivers or the sea, is, as might be anticipated, an exceedingly old custom. Homer mentions the bath as one of the first refreshments offered to a guest; thus, when Ulysses enters the palace of Circe, a bath is prepared for him, and he is anointed after it with costly perfumes. No representation, however, of a bath as we understand it is given upon the Greek vases, bathers being represented either simply washing at an elevated basin, or having water poured over them from above. In later times, rooms, both public and private, were built expressly for bathing, the public baths of the Greeks being mostly connected with the gymnasia. Apparently, by an inversion of the later practice, it was customary in the Homeric epoch to take first a cold and then a hot bath; but the Lacedemonians substituted the hot-air sudorific bath, as less enervating than warm water, and in Athens at the time of Demosthenes and Socrates the warm bath was considered by the more rigorous as an effeminate custom.
The fullest details we have with respect to the bathing of the ancients apply to its luxurious development under the Romans. Their bathing establishments consisted of four main sections: the undressing room, with an adjoining chamber in which the bathers were anointed; a cold room with provision for a cold bath; a room heated moderately to serve as a preparation for the highest and lowest temperatures; and the sweating-room, at one extremity of which was a vapour-bath and at the other an ordinary hot bath. After going through the entire course both the Greeks and Romans made use of strigils or scrapers, either of horn or metal, to remove perspiration, oil, and impurities from the skin. Connected with the bath were walks, covered race-grounds, tennis-courts, and gardens, the whole, both in the external and internal decorations, being frequently on a palatial scale. The group of the Laocoon and the Parnese Hercules were both found in the ruins of Roman baths.
With respect to modern baths, that commonly in use in Russia consists of a single hall, built of wood, in the midst of which is a powerful metal oven, covered with heated stones, and surrounded with broad benches, on which the bathers take their places. Cold water is then poured upon the heated stones, and a thick, hot steam rises, which causes the sweat to issue from the whole body. The bather is then gently whipped with wet birch rods, rubbed with soap, and washed with lukewarm and cold water; of the latter, some pailfuls are poured over his head; or else he leaps, immediately after this sweating-bath, into a river or pond, or rolls in the snow.
The Turks, by their religion, are obliged to make repeated ablutions daily, and for this purpose there is, in every city, a public bath connected with a mosque. A favourite bath among them, however, is a modification of the hot-air sudorific-bath of the ancients introduced under the name of Turkish Bath into other than Islamic countries. A regular accompaniment of this bath, when properly given, is the operation known as 'kneading,' or massage, generally performed at the close of the sweating process, after the final rubbing of the bather with soap, and consisting in a systematic pressing and squeezing of the whole body, stretching the limbs, and manipulating all the joints as well as the fleshy and muscular parts.
Public baths were common in Europe during the late 19th century, but the first English public baths and wash-houses of the kind common in all cities during the late 19th century were established in Liverpool and near the London docks in 1844. In 1846 an act was passed for their encouragement, and a Baths and Wash-houses Act of 1878 authorized the establishment of cheap swimming-baths.
The principal natural warm baths in England are at Bath in Somersetshire (the hottest), and Brixton and Matlock in Derbyshire. The temperature of the Bath springs ranges from 109 to 117 degrees, while that of the Buxton and Matlockwaters scarcely exceeds 82 degrees. The baths of Harrogate, which are strongly impregnated with sulphuretted hydrogen gas, are also of great repute for the cure of obstinate cutaneous diseases, indurations of the glands, etc. The most celebrated natural hot baths in Europe are those of Aix-la-Chapelle, and the various Baden in Germany; Toeplitz, in Bohemia; Bagnieres, Bareges, and Dax, in the south of France; and Spa, in Belgium. Besides the various kinds of water-bath with or without medication or natural mineral ingredients, there are also milk, oil, wine, earth, sand, mud, and electric baths, smoke-baths and gas-baths; but these are as a rule only indulged after specific prescription.
The practice of bathing as a method of cure in cases of disease falls under the head of hydrotherapathy; in the 19th century it was advised that even when bathing was employed simply for pleasure or purification due regard should be paid to the physiological condition of the bather. During the Victorian era in Britain writers were concerned about the potential dangers of bathing, and one warned:
'in many cases cold bathing should be avoided altogether, especially by those who have any tendency to spitting of blood or consumption, by gouty people, or by those who have any latent visceral disease or apoplectic tendency. Wherever the bath is followed by shivering instead of by a healthy reactionary glow, it is undesirable; and a cold bath in the morning after any debauchery or excess in eating or drinking on the previous evening is exceedingly imprudent. Delicate persons and children ought not to bathe in the sea before ten or eleven o'clock in the morning, and in no case should bathing be indulged after a long fast. In cold streams and rivers additional precautions should be taken, the cold plunge, when heated or fatigued, being frequently attended with fatal results. Even warm baths are not wholly free from danger; apoplexy and death having been known to follow a hot bath when entered with a full stomach. As a rule the temperature should not exceed 105 degrees, and they should not be too long continued. Frequent indulgence in them has an enervating effect, though the majority of people need as yet no renewal of Hadrian's prohibitive legislation in this matter.'
The eminent author, George Black, in 1892, while generally encouraging bathing, and describing bathing as 'likely to be of excellent use and efficacy both in the prevention and cure of disease.' Also went on to warn:
'Baths should never be taken immediately after a meal, nor when the body is very much exhausted by fatigue or excitement of any kind, nor during nor just before menstruation; and they should be sparingly and guardedly used by pregnant women.' Research Bath

Gilding is the art of applying gold-leaf or gold in a finely-divided state to surfaces of wood, stone, or metals. It is a very ancient art, being practised among the Egyptians, Greeks, Romans, and Ancient Persians. The processes employed through more modern times have been very varied. Metals are gilded either by what is called chemical gilding, mercurial gilding, by electro-gilding (electro-plating), or by the application of gold-leaf. Copper and brass, for instance, may be gilded by the process called wash or water gilding, with an amalgam of gold and mercury. The surface of the copper, freed from oxide, is covered with the amalgam, and afterwards exposed to heat until the mercury is driven off, leaving a thin coat of gold.
Gilding is also performed by dipping a linen rag in a saturated solution of gold, and burning it to tinder, the black powder thus obtained being rubbed on the metal to be gilded, with a cork dipped in salt water, until the gilding appears. Iron or steel is often gilded by applying gold-leaf, after the surface has been well cleaned, and heated until it has acquired the blue colour which at a certain temperature it assumes. Several leaves of gold are thus applied in succession, and the last is burnished down cold.
One process of chemical gilding was by dipping the article into a solution of gold, what is termed Elkington's solution being composed as follows: 5 oz. (troy) of fine gold; nitro-muriatic acid, 52 oz. (avoirdupois); dissolve by heat, and continue the heat until the cessation of red or yellow vapours; decant the clear liquid; add 4 gallons of distilled water, 20 lbs of pure bicarbonate of potassa and boiling for two hours.
Gilding on wood, plaster, leather, parchment, or paper, is performed by different processes of mechanical gilding. The first of these is oil-gilding, in which gold-leaf is cemented to the work by means of oil-size. In the case of paper or vellum the parts to be gilt receive a coat of gum-water or fine size, and the gold-leaf is applied before the parts are dry. They are afterwards burnished with agate. Lettering and other gilding on bound books are applied without size. The gold-leaf is laid on the leather and imprinted with hot brass types. Brass rollers with thin edges are employed in the same way for lines, and similar tools for other ornaments. When the edges of the leaves of books are to be gilt they are first cut smooth in the press, after which a solution of isinglass in spirits is laid on, and the gold-leaf is applied when the edges are in a proper state of dryness.
Japanner's gilding is another kind of mechanical gilding, which is performed in the same way as oil-gilding, except that instead of gold-leaf a gold dust or powder is employed. Frames of pictures and mirrors, mouldings, etc, are gilt by the application of gold-leaf, or by the cheaper process of 'German gilding,' that is, by tin-foil or silver-leaf, with a yellow varnish above.
Porcelain and other kinds of earthenware, as well as glass, may be gilt by fixing a layer of gold in a powdered state by the action of fire. The gold-dust or powder required in this operation may be obtained by precipitating it from a solution in aqua regia, either by means of iron sulphate or proto-nitrate of mercury. In order that the gold powder may be applied to the surface of the article to be gilt it must be well mixed with some viscous vehicle, such as strongly-gummed water. It is then laid on with a fine camel's-hair brush. Research Gilding
Soil erosion is the wearing away and redistribution of the Earth's soil layer. It is caused by the action of water, wind, and ice, and also by improper methods of agriculture. If unchecked, soil erosion results in the formation of deserts (a process known as desertification). It has been estimated that 20% of the world's cultivated topsoil was lost between 1950 and 1990. If the rate of erosion exceeds the rate of soilformation (from rock and decomposing organic matter), then the land will become infertile.
The removal of forests (the process of deforestation) or other vegetation often leads to serious soil erosion, because plant roots bindsoil, and without them the soil is free to wash or blow away, as in the American dust bowl. The effect is worse on hillsides, and there has been devastating loss of soil where forests have been cleared from mountainsides, as in Madagascar. Improved agricultural practices such as contour ploughing are needed to combat soil erosion. Windbreaks, such as hedges or strips planted with coarse grass, are valuable, and organic farming can reduce soil erosion by as much as 75%. Soil degradation and erosion are becoming as serious as the loss of the rainforest. Research Soil Erosion
Camomile or Chamomile (Matricaria chamomilla) is an annual perennial dwarf herb of the family Compositae found in Europe. The stem is hollow, round, downy, and furrowed. The leaves are pale green, sharply incised, sessile. The flowers are small, yellow-white. Camomile is used in medicine. Internally the infusion of the flowers is used for diarrhoea, dyspepsia, stomach problems, inflammation of the urinary system and painful menstruation. In external use, it is used in infusion, as a compresses over sores and wounds, skin diseases, haemorrhoid and inflammation of the eyes. The ground seeds produce the same effect. The decoction of the flowers or seeds is used to washmouthinflammation. It is a good aid for sitz bath. The steam (vapour) bath of the camomile tea is recommended for asthma in children, or the relieve the symptoms of a cold. Research Camomile
The teasel is a plant of the genus Dipsacus, family Dipsacceae. It is a herb with prickly leaves and flower heads. The British Wild Teasel (Dipsacus fullonum) is also known as Comb and Brush and Venus' Basin. The name teasel comes from the former use of the prickly heads for raising the nap of newly woven cloth. Formerly, water which collected in the leaves was used as an eyewash and to cure warts, hence the alternative name of Venus' Basin. Research Teasel
In Guianan mythology, Aiomum Kondi was the ruler of the gods and the sky. He created mortals in the image of the gods, but was so disgusted by their debauchery that he destroyed them in a fire from heaven. He remade them, and again disappointed he sent a flood to wash them away. However, this time there was one good man, Marerewana, and he and his wife were allowed to survive the flood and regenerate the human race. This is why good and evil and permanent characteristics of mankind, and why the gods take so little interest in mankind. Research Aiomum Kondi
Conjunctivitis is a bacterial or viral infection of the conjunctiva of the eye. It may also be caused by sensitivity to certain cosmetics or drugs. It is a very common complaint characterised by a gritty and burning sensation of the eye and discomfort when moving the eye. The sclera becomes red and irritated and the eyes have a sticky, yellow discharge. In most cases, both eyes become inflamed. The infection is spread easily through towels or wash-cloths.

Salol (phenyl salicylate) is a colourless crystalline substance obtained by the action of phenol on salicylic acid and employed in medicine externally as an antiseptic and internally as a mouthwash and as an intestinal and urinary disinfectant. Research Salol
The stratum corneum is the outer layer of the epidermis. It is composed of flat, dead cells which have lost their nuclei. It is constantly being sloughed off as dandruff. These cells are rubbed off as you move, wear clothes, and wash. Keratin, a horny protein found in hair and fingernails, is also found in the cells of the stratum corneum and prevents evaporation. It also helps to ward off injury because of its toughness. Research Stratum Corneum
