Adulteration is a term not only applied in its proper sense to the fraudulent mixture of articles of commerce, food, drink, drugs, seeds, etc, with noxious or inferior ingredients, but also by magistrates and analysts to accidental impurity, and even in some cases to actual substitution.
The chief objects of adulteration are to increase the weight or volume of the article, to give a colour which either makes a good article more pleasing to the eye or else disguises an inferior one, to substitute a cheaper form of the article, or the same substance from which the strength has been extracted, or to give it a false strength.
Among the adulterations which were commonly practised around 1905 for the purpose of fraudulently increasing the weight or volume of an article are the following: Bread was adulterated with alum or sulphate of copper, which gives solidity to the gluten of damaged or inferior flour; with chalk or carbonate of soda to correct the acidity of such flour; and with boiled rice or potatoes, which enables the bread to carry more water, and thus to produce a larger number of loaves from a given quantity of flour. Wheatflour is adulterated with other inferior flours, as the flour from rice, bean, Indian-corn, potato, and with sulphate of lime, alum, etc. Milk was usually adulterated with water. The adulterations generally present in butter consisted of an undue proportion of salt and water, lard, tallow, and other fats; when of poor quality it was frequently coloured with a little annatto, and, at times, with the juice of carrots. Genuine butter should not contain less than 80 percent of butter-fat. Cheese was also coloured with annatto and other substances. Tea was adulterated chiefly in China with sand, iron-filings, chalk, gypsum, Chinaclay, exhausted tea leaves, and the leaves of the sycamore, horse-chestnut, and plum, whilst colour and weight were added by black-lead, indigo, Prussian-blue (one of the deleterious ingredients used by the Chinese in converting the lowest qualities of black into green teas), gum, turmeric, soapstone, catechu, and other substances.
Confections were adulterated with flour and sulphate of lime. Preserved vegetables were kept green and poisoned by salts of copper. The acridity of mustard is commonly reduced by flour, and the colour of the compound is improved by turmeric. Pepper was adulterated with linseed-meal, flour, mustard husks, etc. Colour was given to pickles by salts of copper, acetate of copper, etc. Ale was adulterated with common salt, Cocculus Indicus, grains of paradise, quassia, and other bitters, sulphate of iron, alum, etc. Porter and stout were mixed with sugar, treacle, salt, and an excess of water. Brandy was diluted with water, and burned sugar was added to improve the colour; sometimes bad whisky was flavoured and coloured so as to resemble brandy, and sold under its name.
Gin was mixed with excess of water, and flavouring matters of various kinds, with alum and tartar, were added. Rum was diluted with water, and the flavour and colour kept up by the addition of cayenne and burned sugar. For champagnegooseberry and other inferior wines were often substituted. Port was manufactured from red Cape and other inferior wines, the body, flavour, strength, and colour being produced by gum-dragon, the washings of brandy casks, and a preparation of German bilberries. Cheap brown sherry was mixed with Cape and other low-priced brandies, and was flavoured with the washings of brandy casks, sugar-candy, and bitter almonds. Pale sherries were produced by gypsum, by a process called plastering, which removes the natural acids as well as the colour of the wine. Other wines were adulterated with elderberry, logwood, Brazil-wood, cudbear, red beetroot, etc, for colour; with lime or carbonate of lime, carbonate of soda, carbonate of potash, and litharge, to correct acidity; with catechu, sloe-leaves, and oak-bark for astringency; with sulphate of lime and alum for removing colour; with cane-sugar for giving sweetness and body; with alcohol for fortifying; and with ether, especially acetic ether, for giving bouquet and flavour.
Medicines, such as jalap, opium, rhubarb, cinchonabark, scammony, aloes, sarsaparilla, squills, etc, were mixed with various foreign substances. Castor-oil has been adulterated with other oils; and inferior oils were often. mixed with cod-liver oil. Cantharides were often mixed with golden-beetle and also artificially-coloured glass.
The adulteration of seeds was largely practised also, the seed which forms the adulterant being of course of the most worthless kind that can be had. Thus turnip-seed was mixed with rape, wild mustard, or charlock, which are steamed and kiln-dried to destroy their vitality, so as to evade detection in the progress of growth; old and useless turnip-seed was also used fraudulently mixed with fresh seeds. Clover was also much mixed with plantain and mere weeds.
Acts against adulteration have been passed in various countries and at various times. In Britain there was a law against it as early as 1267. Research Adulteration
The ammoniaphone was an instrument of the 19th and early 20th centuries, consisting of a metallic tube containing some substance saturated with ammonia, peroxide of hydrogen, and a few flavouring compounds, fitted with a mouthpiece to breathe through, which was said to render the voice strong, clear, rich, and ringing by the inhalation of the ammoniacal vapour. It was invented by Dr. Carter Moffat, and was suggested by the presence of ammonia in some quantity in the atmosphere of Italy - the country of fine singers. Research Ammoniaphone
Guano (from the Peruvian huano meaning dung) is the partially decomposed and dry excrement of sea-birds. Since the 19th century it has been highly prized as a manure, and led to the claims and disputes of the many tiny islands and atolls in the Pacific Ocean (such as the Gilbert Islands, Line Islands etc) as the western countries sought to lay sole claim to the collection of the vast tons of guano deposited on these islands by their bird populations.
The name guano has also been extended to accumulations of a similar kind from land birds, and even from bats in caverns. Owing to the fact that rain washes such deposits away, great accumulations of guano exist principally in hot and dry tropical regions. The most important of all were the deposits on the Chincha Islands off the coast of Peru, which yielded a considerable revenue to the country, but were quite exhausted by 1900. From 1853 to 1872 about 8,000,000 tons were obtained from these islands. The guano which was found there was from 60 to 80 or 100 feet (as much as 30 meters) in thickness, and was entirely due to the droppings, accumulated for many ages, of the innumerable sea-birds which make these islands their resting-place and breeding-ground. Other deposits of less extent have from time to time been found, and Peru remained the chief source of supply, its deposits being worked under the Chilian government.
Guano varies extremely in composition, but it may be roughly divided into nitrogenous and phosphatic. The first of these contains about 21 per cent of ammonia. This is the case with the Peruvian variety, which contains almost all the inorganic matter required by a plant, and that in a highly available form, so that it is looked upon as one of the best of all fertilizing agents for different crops. Its use as a manure was known to the native Peruvians centuries ago, but no attention was paid to the accounts by modern travellers of its wonderful efficacy until Von Humboldt brought some to Europe and had it analysed. It began to be brought to Europe about 1846. It was used raw or in its natural state, but most of the phosphatic guanos (some of which hardly deserve the name of guano) required to be dissolved by sulphuric acid before using. There were also manures known fish guano, prepared from fish or fish refuse, flesh guano, blood guano, etcc. Large quantities of fish guano were made in the United States from the menhaden, the oil being first extracted. Research Guano
Westrumite was a road-dust preventing material composed primarily of petroleum and ammonia. It was developed around 1900 in response to the spread of motoring and the dust raised by cars using the roads. Research Westrumite
An animal is an organized and sentient living being. Life in the earlier periods of natural history was attributed almost exclusively to animals. With the progress of science, however, it was extended to plants. In the case of the higher animals and plants there is no difficulty in assigning the individual to one of the two great kingdoms of organic nature, but in their lowest manifestations, the vegetable and animal kingdoms are brought into such immediate contact that it becomes almost impossible to assign them precise limits, and to say with certainty where the one begins and the other ends. From form no absolute distinction can be fixed between animals and plants. Many animals, such as the sea-shrubs, sea-mats, etc, so resemble plants in external appearance that they were looked upon as such. With regard to internal structure no line of demarcation can be laid down, all plants and animals being, in this respect, fundamentally similar; that is, alike composed of molecular, cellular, and fibrous tissues. Neither are the chemical characters of animal and vegetable substances more distinct. Animals contain in their tissues and fluids a larger proportion of nitrogen than plants, whilst plants are richer in carbonaceous compounds than the former. In some animals, moreover, substances almost exclusively confined to plants are found. Thus the outer wall of Sea-squirts contains cellulose, a substance largely found in plant-tissues; whilst chlorophyll, the colouring-matter of plants, occurs in Hydra and many other lower animals.
Power of motion, again, though broadly distinctive of animals, cannot be said to be absolutely characteristic of them. Thus many animals, as oysters, sponges, corals, etc, in their mature condition are rooted or fixed, while the embryos of many plants, together with numerous fully developed forms, are endowed with locomotive power by means of vibratile, hair-like processes called cilia. The distinctive points between animals and plants which are most to be relied on are those derived from the nature and mode of assimilation of the food. Plants feed on inorganic matters, consisting of water, ammonia, carbonic acid, and mineral matters. They can only take in food which is presented to them in a liquid or gaseous state. The exceptions to these rules are found chiefly in the case of plants which live parasitically on other plants or on animals, in which cases the plant may be said to feed on organic matters, represented by the juices of their hosts. Animals, on the contrary, require organized matters for food. They feed either upon plants or upon other animals. But even carnivorous animals can be shown to be dependent upon plants for subsistence; since the animals upon which Carnivora prey are in their turn supported by plants. Animals, further, can subsist on solid food in addition to liquids and gases; but many animals (such as the Tapeworms) live by the mere imbibition of fluids which are absorbed by their tissues, such forms possessing no distinct digestive system.
Animals require a due supply of oxygen gas for their sustenance, this gas being used in respiration. Plants, on the contrary, require carbon dioxide. The animal exhales or gives out carbon dioxide as the part result of its tissue-waste, whilst the plant taking in this gas is enabled to decompose it into its constituent carbon and oxygen. The plant retains the former for the uses of its economy, and liberates the oxygen, which is thus restored to the atmosphere for the use of the animal. Animals receive their food into the interior of their bodies, and assimilation takes place in their internal surfaces. Plants, on the other hand, receive their food into their external surfaces, and assimilation is effected in the external parts, as are exemplified in the leaf-surfaces under the influence of sunlight. All animals possess a certain amount of heat or temperature which is necessary for the performance of vital action. The only classes of animals in which a constantly-elevated temperature is kept up are birds and mammals. The bodily heat of the former varies from 100 degrees Fahrenheit to 112 degrees Fahrenheit and of the latter from 96 degrees to 104 degrees. The mean or average heat of the human body is about 99 degrees Fahrenheit, and it never falls much below this in health. Below birds animals are named cold-blooded, this term meaning in its strictly physiological sense that their temperature is usually that of the medium in which they live, and that it varies with that of the surrounding medium, Warm-blooded animals, on the contrary, do not exhibit such variations, but mostly retain their normal temperature in any atmosphere. The cause of the evolution of heat in the animal body is referred to the union (by a process resembling ordinary combustion) of the carbon and hydrogen of the system with the oxygen taken in from the air in the process of respiration.

Tobacco is the name given to the leaves of those varieties of the Nicotiana which are prepared in different forms for use as a narcotic. It is generally manufactured for smoking, but also for chewing and as snuth.
The word tobacco is probably derived from tobaco, the name given to a peculiar Y-shaped instrument used by the old inhabitants of the island of Santo Domingo for inhaling tobacco-smoke through the nostrils. Other authorities claim that the name of the herb is derived from the Mexican word tabacco. Columbus and his party made the earliest European reference to tobacco on their return from the voyage to Cuba in 1492. The tobacco plant was first brought to Europe in 1558 by Francisco Fernandes, a Spanish physician. The wonderful healing properties which the plant was supposed to possess caused the habit of smoking and snuff-taking to spread with great rapidity over almost the whole of Europe. Jean Nicot, French ambassador to Portugal, who gives his name to the genusNicotiana, sent a present of tobacco seeds to Catherine de'Medici, and she initiated in France the snuff-taking habit as a cure for headache. This habit soon spread to Scotland and Ireland, where it remained popular long after the smoking habit had become established in England.
The smoking of tobacco was really started by English example. In 1586, Ralph Lane, the first governor of Virginia, and Sir Francis Drake brought smoking materials and implements to Sir Walter Raleigh, who very rapidly popularised the custom.
Most of the tobacco used in the 17th and 18th centuries was grown in Virginia by English colonists, whose industry was carefully protected by laws prohibiting the production of tobacco in the British Isles.
There are about 50 species of Nicotiana, most of them indigenous to America. Of these, three varieties are in general use by smokers: (1) Nicotiana tabacum, the Virginian variety, originally derived from the South or Central American seed, and now cultivated in almost all temperate and warmer climates. (2) Nicotianarustica, grown principally in Turkey, Syria, and India. This is milder in flavour, and is principally used for the manufacture of cigarettes. It burns too quickly for a pipe tobacco. (3) Nicotiana Persica, or Persian tobacco, which is good for pipe tobacco, but not sufficiently uniform for the manufacture of cigars.
The tobacco plant is a coarse, rank-growing annual. Its stem is simple and unbranched, and grows to a height of about two meters, terminating in a bunch of yellow or rose-coloured flowers. The East Indian variety is slightly different, producing a green tobacco from a smaller plant. It is derived from the Mexican seed, and is also cultivated in Southern Germany and Hungary.
The tobacco plant can be cultivated in every part of the world, but with widely varying measures of success. It is grown in British gardens for the sake of its flowers. Clayey, moist soils produce tobaccos which are dark brown or reddish in colour when cured. Bright and yellow tobaccos are grown on sandy soils, and the leaf of this variety is thinner. The bright tobacco produced in Virginia and North Carolina is all grown in loose sandy soil with a clay subsoil.
The tobacco seeds are generally sown in nursery beds, and set out later. About 3OOOOO to 4000000 go to the ounce, and this produces about 40,000 plants, for which 50 square yards of nursery bed are sufficient. The seeds are sown at the end of March or beginning of April, in rich, heavy soil which has been carefully prepared and fertilised. The seedlings remain in the nursery from fifty to sixty days, during which time the fields are well tilled and manured. Transplanting is done on a warm, rainy day, and the young plants set in ridges varying from one to four feet in width. Ridges of one to one and a half feet are most usual in Cuba and Sumatra, as the wider ridge produces a leaf which is too coarse for the purpose of cigar-making.
The crop takes another two months until it flowers, and at this stage the buds are pinched off or 'topped', and some of the leaves pruned, so that only a certain number are left to ripen. For cigar-tobacco, from 15 to 20 leaves are left on the plant; for the best smoking tobaccos, 10 to 12 leaves. Plants which have been topped form suckers, and in Florida these are left to produce a second, although inferior, sucker crop.
The leaves take about 35 days to ripen after the plants are topped and pruned. The ripening leaf changes from a dark to a lighter yellowish-green colour, and is often mottled and becomes gummy. The ripe leaf cracks and creases when folded. The lower leaves ripen first, and for the best tobaccos the leaves are picked singly ;
as they ripen. For the bulk of the tobaccos, however, the whole plant is cut when the middle leaves are ripe. Warm, cloudy days are best for cutting, and the plants are not gathered in hot sunshine or when they are wet from rain or dew.
After harvesting the plants are left in the open to wilt, and are then conveyed to the drying-house or ventilating-barn, where they are straddled across tiers of poles and dried in a temperature which is raised to 170° F for four to five days. On damp days the moisture is allowed to penetrate into the drying-house to make the leaves pliable.
The plants are then taken down and stripped, and the leaves sorted into firsts, seconds, and lugs - the name given to the inferior leaves. They are formed into hands containing ten to twelve leaves, and these are left in heaps and fermented at a temperature of about 130° F for from three to four weeks. The heaps are shuffled from time to time, to allow all the leaves to assume a uniform brown tint. This process is called the fermenting or sweetening process. In the non-fermenting processes the leaves are simply sun-cured, or sun-dried, and this tobacco is used chiefly for chewing tobaccos. In the fermenting process the starch and sugar in the leaf are decomposed, but they are retained in the sun-dried process. Lastly, the leaves are packed carefully in hogsheads for shipment.
Tobacco leaf is used for making into various smoking mixtures, roll tobacco, cake or plug, cigars, cigarettes, and snuff. For snuff the leaf requires very careful fermentation during several weeks. It is ground up and flavoured so as to produce the greatest possible amount of free ammonia, free nicotine, and other aromatic scents. Syria produces and manufactures a smoking tobacco which is known as Latakia. It is similar to Turkish-grown tobacco, but differently treated. The plants are not topped. The seeds as well as the leaves are included in the curing, this taking place in the smoke of a fire of evergreen-oak, which gives a black colour and a peculiarly strong flavour to the tobacco.
Tobacco for pipe-smoking is mostly grown in the USA, the chief states being Kentucky, North Carolina, and Virginia. Louisiana grows a dark, almost black, and very strong tobacco known as perique. Cigarette tobaccos are principally imported from Virginia, and Turkish and Egyptian cigarettes are also in great demand. The Egyptian cigarette is made from Turkish leaf, as the cultivation of tobacco in Egypt was prohibited in 1891. The best cigar tobaccos are grown in Cuba. A very good cigar leaf is also produced in Jamaica, Sumatra and North Borneo.
Since the introduction of tobacco into England, it has been subject to continuous legislation and import duties. In the early days a certain quantity of tobacco was grown in England for domestic consumption, and quite a considerable trade was done with Turkey, which, at that time, imported her tobacco supplies from England. Queen Elizabeth imposed a tax of 2d per Ib on imported tobacco. In 1621 James I increased this to 6s. lOd. per Ib.
During the American War of Independence, England's source of supply and the revenue there from were temporarily suspended, and tobacco was again widely planted in England, although the prohibition laws had not been repealed. These laws had never applied to Scotland, and to reimburse themselves for the loss of revenue during the non-importation of American tobacco, the Government purchased the Scotch tobacco crops at the fixed price of 4d. per Ib., thus temporarily creating a Government monopoly in tobacco. The ban on the growing of tobacco in the British Isles, renewed in 1782 in England, and in 1830 in Ireland, was modified later in the 19th century, and tobacco can now be cultivated under licence.
During the late 20th century an American-led ban on tobacco smoking supposedly because of the connection with lung cancer, but more likely under pressure from the pharmaceutical lobby, in public places slowly extended to Britain, with Scotland banning the smoking of tobacco in pubs and clubs in 2005.

Count Claude Louis Bethollet was a French chemist. He was born in 1748 and died in 1822. He studied medicine; became connected with Lavoisier and was admitted in 1780 a member of the Academy of Sciences at Paris. In 1794 he became professor in the normal school there. He followed Bonaparte to Egypt, and returned with him in 1799. Notwithstanding the various honours conferred on him by Napoleon he voted in 1814 for his dethronement, and was made a peer by Louis XVIII. His chief chemical discoveries were connected with the analysis of ammonia, the use of chlorine in bleaching, the artificial production of nitre, etc. His most important works were his Essai de Statique Chimique (1803), and the Methode de Nomenclature Ohimique (1787).

Fritz Haber was a German chemist. He was born in 1868 and died in 1934. His conversion of atmospheric nitrogen to ammonia opened the way for the synthetic fertilizer industry. His study of the combustion of hydrocarbons led to the commercial cracking or fractional distillation of natural oil (petroleum) into its components (for example, diesel, gasoline, and paraffin) . In electrochemistry, he was the first to demonstrate that oxidation and reduction take place at the electrodes; from this he developed a general electrochemical theory. At the outbreak of war, the German Army asked the Institute to investigate substitutes for explosive in shells, and poison gas was suggested. Haber, after watching early trials with gas shells, proposed releasing gas from cylinders. He became one of the principals in the German chemical warfare effort, devising weapons and gas masks, leading to protests against his Nobel Prize, awarded in 1918. Research Fritz Haber
Ludwig Mond was a German chemist. He was born in 1838 at Cassel and died in 1909. Educated at Marburg and Heidelburg universities he went to England in 1862 to introduce a process for the recovery of sulphur from alkali waste and in 1873 partnered John Brunner to invent a process for creating soda - the Silvay or ammonia process - erecting a works near Norwich for the manufacture of soda.
