Pennsylvania, officially the Commonwealth of Pennsylvania, is a state spanning the Mid-Atlantic, Northeastern, Appalachian, and Great Lakes regions of the United States. Pennsylvania borders Delaware to its southeast, Maryland to its south, West Virginia to its southwest, Ohio to its west, Lake Erie and the Canadian province of Ontario to its northwest, New York state to its north, and the Delaware River and New Jersey to its east.

Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania and the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. It is one of the most historically significant cities in the United States and served as the nation's capital city until 1800. Philadelphia is the nation's sixth-largest city with a population of 1,603,797 as of the 2020 census. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of the world's largest metropolitan regions with 6.245 million residents in 2020. Philadelphia is known for its extensive contributions to American history and for its role in the life sciences, business and industry, art, literature, and music.

The Cambrian Pottery was founded in 1764 by William Coles in Swansea, Glamorganshire, Wales. In 1790, John Coles, son of the founder, went into partnership with George Haynes, who introduced new business strategies based on the ideas of Josiah Wedgwood. Lewis Weston Dillwyn became a partner in 1802 and sole owner when George Haynes left the pottery in 1810. In 1811 Dillwyn took T.& J. Bevington into partnership, the company becoming known as Dillwyn & Co.

The Library Company of Philadelphia (LCP) is a non-profit organization based on Locust Street in Center City Philadelphia. Founded in 1731 by Benjamin Franklin as a library, the Library Company of Philadelphia has accumulated one of the most significant collections of historically valuable manuscripts and printed material in the United States.

The Historical Society of Pennsylvania is a historic research facility headquartered on Locust Street in Center City Philadelphia. It is a repository for millions of historic items ranging across rare books, scholarly monographs, family chronicles, maps, press reports and varied ephemera, reaching back almost 300 years, and accessible on the society’s website.

Gout is a form of inflammatory arthritis characterized by recurrent attacks of a red, tender, hot and swollen joint, caused by the deposition of needle-like crystals of uric acid known as monosodium urate crystals. Pain typically comes on rapidly, reaching maximal intensity in less than 12 hours. The joint at the base of the big toe is affected (Podagra) in about half of cases. It may also result in tophi, kidney stones, or kidney damage.

Porcelain is a ceramic material made by heating raw materials, generally including kaolinite, in a kiln to temperatures between 1,200 and 1,400 °C. The greater strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and formation of the mineral mullite within the body at these high temperatures. End applications include tableware, decorative ware such as figurines, and in technology and industry such as electrical insulators and laboratory ware.

Botany, also called plant science(s), plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word βοτάνη meaning "pasture", "herbs" "grass", or "fodder"; βοτάνη is in turn derived from βόσκειν, "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists study approximately 410,000 species of land plants of which some 391,000 species are vascular plants, and approximately 20,000 are bryophytes.

Conchology is the study of mollusc shells. Conchology is one aspect of malacology, the study of molluscs; however, malacology is the study of molluscs as whole organisms, whereas conchology is confined to the study of their shells. It includes the study of land and freshwater mollusc shells as well as seashells and extends to the study of a gastropod's operculum.

Dillwynella is a genus of sea snails, marine gastropod mollusks in the family Skeneidae.

Sea snail is a common name for slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell.

The Skeneidae are a speciose family of minute to small marine gastropod molluscs in the superfamily Trochoidea.

Dillwynia is a genus of about 20 species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in this genus are shrubs with simple leaves and yellow or red and yellow flowers similar to others in the family.

The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family, are a large and agriculturally important family of flowering plants. It includes trees, shrubs, and perennial or annual herbaceous plants, which are easily recognized by their fruit (legume) and their compound, stipulate leaves. The family is widely distributed, and is the third-largest land plant family in number of species, behind only the Orchidaceae and Asteraceae, with about 765 genera and nearly 20,000 known species.
