Petroleum—a natural mineral oil—was referred to as early as the Old Testament. The word petroleum means rock oil [from the Greek petros (rock) and elaion (oil)]. It has been found for centuries seeping out of the ground, for example, in the Los Angeles basin in what are now called the La Brea tar pits. Vast deposits were found in Europe, Asia, the Americas, and Africa. 

Crude preparations of mescaline (61) from peyote were first reported by the Spanish as they learned of its use from the natives of Mexico during the Spanish invasion of that country in the sixteenth century. The colorful history (44) of mescaline has drawn attention to its use as a hallucinogen and even today it is in use among natives of North and South America. Although in connection with dmg abuse complaints, mescaline is considered dangerous, it has been reported (45) that it is not a narcotic nor is it habituating. It was also suggested that its sacramental use in the Native American Church of the United States be permitted since it appears to provoke only visual hallucination while the subject retains clear consciousness and awareness. 

Such repositioning inevitably means reduced production volume, and for the first time this century production in the last decade has been below that a decade earUer (Eig. 9). Most capacity reductions have been in North America and especiaUy eastern Europe. This has been offset in part by capacity increases in the Ear East. Rayon is no longer a significant component of carpets, and has lost the disposable diaper coverstock business to cheaper and more easUy processed polypropylene. It has, however, gained share in health and hygiene products and is now a principal component of tampons worldwide. 

In North America, quicklime was produced locally as early as 1635 in Rhode Island. It was not until 1733, when lime was shipped by boatioad from Rockland, Maine, to Boston, that lime manufacture was estabUshed as a significant iadustry in commerce. The commercial hydration of lime is a relatively recent development initiated in 1904. Technical progress has allowed the industry to advance rapidly during the latter part of the twentieth century. 

In the latter twentieth century, spent automotive catalysts have emerged as a significant potential source of secondary Pt, Pd, and Rh. In North America, it has been estimated that 15.5 metric tons per year of PGM from automotive catalysts are available for recycling (22). However, the low PGM loading on such catalysts and the nature of the ceramic monoliths used have required the development of specialized recovery techniques as well as the estabhshment of an infrastmcture of collection centers. These factors have slowed the development of an automotive catalyst recycling iadustry.

Asiatic clams are freshwater moUusks. They probably origiaated ia China or eastern Asia and were iatroduced iato North America and Europe ia the past century. They were originally found ia warm water but their territory now extends to Minnesota. They have not yet been seen ia Canadian rivers or lakes. 

The carbonated beverage has its origin in the study of mineral waters in Europe in the sixteenth century. In the late eighteenth century, artificial mineral waters were investigated for their medicinal properties both in Europe and America. The first commercial artificial mineral water was manufactured in Europe during the 1780s and in America in the early 1800s. 

It is said that Alexander the Great introduced Indian cotton into Egypt in the fourth century BC, and from there it spread to Greece, Italy, and Spain. During the year AD 700, China began growing cotton as a decorative plant, and AD 798 saw its introduction into Japan. Early explorers in Pern found cotton cloth on exhumed mummies that dated to 200 BC. Cotton was found in North America by Columbus in 1492. About 300 years later, the first cotton mill was built in Beverly, Massachusetts, and in 1794 EH Whitney was granted a patent for the invention of the cotton gin. 

Cultivation of madder reached its highest degree in France and Holland dufing the sixteenth century. In North America, growing conditions were quite suitable, but madder was never cultivated there to any great extent (10). 

Natural rubber can be obtained from the sap of a number of plants and trees, the most common source is the Hevea brasiliensis tree. Although natural rubber was known in Central and South America before the arrival of Christopher Columbus in 1492, the first use as an adhesive was established in a patent dated in 1891. As rubber became an important part of the industrial revolution, the rubber adhesives market grew in importance. To comply with the increasing demand on natural rubber materials, plantations of Hevea brasiliensis trees were established in southeast Asia in the early 20th Century, mainly to supply the demand from the automobile industry. 

Although estimates of their abundances vary considerably, Pd and Pt (approximately 0.015 and 0.01 ppm respectively) are much rarer than Ni. They are generally associated with the other platinum metals and occur either native in placer (i.e. alluvial) deposits or as sulfides or arsenides in Ni, Cu and Fe sulfide ores. Until the 1820s all platinum metals came from South America, but in 1819 the first of a series of rich placer deposits which were to make Russia the chief source of the metals for the next century, was discovered in the Urals. More recently however, the copper-nickel ores in South Africa and Russia (where the Noril sk-Talnakh deposits are well inside the Arctic Circle) have become the major sources, supplemented by supplies from Sudbury. 

Cold-hammering was used in the late Stone Age to produce plates of gold for ornamental purposes, and this metal has always been synonymous with beauty, wealth and power. Considerable quantities were accumulated by ancient peoples. The coffin of Tutankhamun (a minor Pharaoh who was only 18 when he died) contained no less than 112 kg of gold, and the legendary Aztec and Inca hoards in Mexico and Peru were a major reason for the Spanish conquests of Central and South America in the early sixteenth century. Today, the greatest hoard of gold is the 30000 tonnes of bullion (i.e. bars) lying in the vaults of the US Federal Reserve Bank... 

Silver is widely distributed in sulfide ores of which silver glance (argentite), Ag2S, is the most important. Native silver is sometimes associated with these ores as a result of their chemical reduction, while the action of salt water is probably responsible for their conversion into hom silver , AgCl, which is found in Chile and New South Wales. The Spanish Americas provided most of the world s silver for the three centuries after about 1520, to be succeeded in the nineteenth century by Russia. Appreciable quantities are now obtained as a byproduct in the production of other metals such as copper.
