The manta ray (Manta birostris), is the largest of the rays, with the largest known specimen having been more than 7.6 m (about 25 ft) across, with a weight of about 2,300 kg (about 5,000 lbs). It ranges throughout all tropical waters of the world, typically around coral reefs. Mantas have been given a variety of common names, including Atlantic manta, Pacific manta, devilfish, and just manta. Some people just call all members of the family stingrays, though stingrays comprise a separate family of rays (Dasyatidae). Recent studies have discovered that what is called manta ray are at least two different species, one smaller local and one much larger and migratory.

An illustration of a man holding a sea cucumber. The sea cucumber (also known as trepang and sea slug) is an echinoderm of the class Holothuroidea, with an elongated body and leathery skin, which is found on the sea floor worldwide. It is so named because of its cucumber-like shape. The body contains a single, branched gonad. Like all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue. These can sometimes be enlarged to flattened plates, forming an armor.

George Whitefield (December 16, 1714 – September 30, 1770), was a preacher in the Church of England and one of the leaders of the Methodist movement. He first took to preaching in the open air on Hanham Mount, Kingswood, in southeast Bristol. A crowd of 20,000 people gathered to hear him. Even larger crowds – Whitefield himself estimated 30,000 – met him in Cambuslang in 1742. Benjamin Franklin once attended a revival meeting in Philadelphia and was greatly impressed with Whitefield's ability to deliver a message to such a large audience.

The guillotine was a device used for carrying out executions by decapitation. It consists of a tall upright frame from which a heavy blade is suspended. This blade is raised with a rope and then allowed to drop, severing the victim's head from his or her body. The device is noted for long being the main method of execution in France and, more particularly, for its use during the French Revolution. The guillotine also "became a part of popular culture, celebrated as the people's avenger by supporters of the Revolution and vilified as the preeminent symbol of the Terror by opponents.

An illustration of a crowded promenade. An esplanade is a long, open, level area, usually next to a river or large body of water, where people may walk. This allows people to promenade along the sea front, usually for recreational purposes, whatever the state of the tide, without having to walk on the beach. Esplanades became popular in Victorian times when it was fashionable to visit seaside resorts. The original meaning of esplanade was a large, open, level area outside fortress or city walls. Esplanade and promenade are sometimes used interchangeably, but that is a mistake. A promenade can be anywhere, and it is exclusively for walking, while an esplanade is for walking but also can include large boulevards or avenues with cars.

Twenty-six species have been described, six of which occur in North America. Some species are considered to have subspecies as well. Although most people consider tent caterpillars only as pests due to their habit of defoliating trees, they are among the most social of all caterpillars and exhibit many noteworthy behaviors.

During this early period Virginia's population grew with the introduction of settlers and servants into the burgeoning plantation economy. Land from the Native Americans was appropriated by force and treaty, including the Treaty of 1677, which made the signatory tribes tributary states. In 1619 the House of Burgesses was established as the colony's elected governance, and African servants were first introduced, with slavery being codified in 1661.
