"Battle ground at Concord. This view, looking southeast, is from the road leading to the village, by the way of the North Bridge, to the residence of Mr. Prescott Barrett. The point from which the sketch was made is upon an elevation a little north of that where the militia assembled under Colonel Barrett. The stream of water is the Concord, or Sudbury River. The site of the North Bridge is at the monument seen in the center of the picture. The monument stands upon the spot where the British were stationed, and in the plain, directly across the river from the monument, is the place where Davis and Hosmer, of the American militia, were killed. The house, the roof and gable of which are seen in the distance, just on the left of the largest tree, was the residence of the Reverend Dr. Ripley (afterward a chaplain in the army) at the time of the skirmish. It is upon the road elading to Concord village, which lies nearly half a mile beyond."—Lossing, 1851

Chess is a recreational and competitive game played between two players. Sometimes called Western chess or international chess to distinguish it from its predecessors and other chess variants, the current form of the game emerged in Southern Europe during the second half of the 15th century after evolving from similar, much older games of Indian and Persian origin. Today, chess is one of the world's most popular games, played by millions of people worldwide at home, in clubs, online, by correspondence, and in tournaments.

A dark mystery shrouds the fate of the eldest son of Louis XVI of France and Marie Antoinette, who was eight years of age at the time his father was murdered by the Jacobins. After the downfall of Robespierre and his fellows, it was declared that the prince died in prison in 1795, while the royalists believed he had been secretly hidden away in the United States. Curious facts and circumstances pointed to Rev. Eleazar Williams, a reputed half-breed Indian, of the Caughanawaga tribe, near Montreal, as the surviving prince, who, for almost sixty years, had been hidden from the world in that disguise.

The Goldfish, Carassius auratus, was one of the earliest fish to be domesticated, and is still one of the most commonly kept aquarium fish and water garden fish. A relatively small member of the carp family, the goldfish is a domesticated version of a dark-gray/brown carp native to East Asia. It was first domesticated in China and introduced to Europe in the late 17th century. Goldfish can grow to a maximum length of 23 inches (159 cm) and a maximum weight of 9.9 pounds (4.5 kg), although this is rare; few goldfish reach even half this size. The oldest recorded goldfish lived to 49 years, but most household goldfish generally live only six to eight years, due to being kept in bowls.

"It was in Central France, and mainly along the Loire, that the systematic development of vaulted church architecture began. Naves covered with barrel-vaults, sometimes of pointed section, appear in a number of large churches built during the eleventh and twelfth centuries, with apsidal and transeptal chapels and aisles carried around the apse, as in Notre-Dame du Port at Clermont-Ferrand. The thrust of these ponderous vaults was clumsily resisted by half-barrel vaults over the side aisles, transmitting the strain to massive side-walls."

The Goliath beetles are among the largest insects on Earth, if measured in terms of size, bulk and weight. They are members of subfamily Cetoniinae, within the scarab beetle family. Goliath beetles can be found in many of Africa's tropical forests, where they feed primarily on tree sap and fruit. Little appears to be known of the larval cycle in the wild, but in captivity, Goliathus beetles have been successfully reared from egg to adult using protein-rich foods such as commercial cat and dog food. Goliath beetles measure from 60–110 millimetres (2.4–4.3 in) for males and 50–80 millimetres (2.0–3.1 in) for females, as adults, and can reach weights of up to 80–100 grams (2.8–3.5 oz) in the larval stage, though the adults are only about half this weight. The females range from a dark brown to silky white, but the males are nomally brown/white/black or black/white.

The whole mass of the rows of seats was supported by a solid substructure of piers and arches, which formed passages of three stories one above the other, retaining the circular form of the building; whilst externally they formed arcades, which were surrounded with half-columns or piers with entablatures over them. The exterior of the straight portion of the building, which contained the stage and some chambers connected with it, was generally surrounded by a portico. The theaters were either open, or were protected against the sun and rain by an awning stretched over them."
