Her Majesty's Royal Palace and Fortress, more commonly known as the Tower of London (and historically as The Tower), is a historic monument in central London, England, on the north bank of the River Thames. The Tower of London is often identified with the White Tower, the original stark square fortress built by William the Conqueror in 1078. However, the tower as a whole is a complex of several buildings set within two concentric rings of defensive walls and a moat. The tower's primary function was a fortress, a royal palace, and a prison (particularly for high status and royal prisoners).

An illustration of a brown pelican with a fish in it's mouth and a sea gull resting on his back. The brown pelican is the smallest of the eight species of pelican, although it is a large bird in nearly every other regard. It lives strictly on coasts from Washington and Virginia south to northern Chile and the mouth of the Amazon River, as well as the island of Saut d'Eau in Trinidad and Tobago. Some immature birds may stray to inland freshwater lakes. After nesting, North American birds move in flocks further north along the coasts, returning to warmer waters for winter. Their young are hatched in broods of about 3, and eat around 150 lbs. of fish in the 8-10 month period they are cared for. Gulls (often informally Seagulls) are birds in the family Laridae. They are typically medium to large birds, usually gray or white, often with black markings on the head or wings. They typically have harsh wailing or squawking calls. They have stout, longish bills, and webbed feet.

John Coleridge Patteson (April 1, 1827 – September 20, 1871) was an Anglican bishop and martyr. On 20 September 1871 he was murdered on the island of Nukapu in the Solomon Islands, where he had landed alone. Natives killed him as revenge against the abduction of some natives by white men months earlier. His death became a cause celebre in England and increased interest both in missionary work and in improvement of the working conditions in Melanesia. His life is celebrated in the Church of England as a saintly one.

An egret is any of several herons, most of which are white or buff, and several of which develop fine plumes (usually milky white) during the breeding season. Many egrets are members of the genera Egretta or Ardea which contain other species named as herons rather than egrets. The distinction between a heron and an egret is rather vague, and depends more on appearance than biology. The word "egret" comes from the French word "aigrette", referring to the long filamentous feathers that seem to cascade down an egret's back during the breeding season.

Johann Gottlieb Rall (ca. 1726 - December 26, 1776 ) was a German colonel in command of Hessian troops in Trenton, New Jersey. By 1776, Rall belonged to the infantry regiment of the 1st Division under General Phillip Leopold von Heister and commanded approximately 1,200 men fighting for Great Britain in the American Revolutionary War. He was at the Battle of Brooklyn at Flatbush, the Battle of White Plains, the Battle of Long Island, and figured prominently in the Battle of Trenton. At the Battle of Trenton, Rall was mortally wounded and taken back to his headquarters where he died. <p>"Rall's head-quarters. This is a frame building standing upon Warren Street, opposite Perry, near the corner of Bank Alley. The buildings on the left are also of ante-Revolutionary origin. This house was a tavern at the time, kept by Stacey Potts, the grandfather of Stacey G. and Joseph C. Potts, Esqrs., of Trenton. In a pane of glass, in the front window on the left of the front door, lower story, may be seen a hole made by a bullet, shot during the battle. Colonel Rall died in the front room in the second story, immediately over this window. It is related that a daughter of Mr. Potts, who was at a neighbor's when the firing commenced, was running toward her father's house, when a musket-ball struck her comb from her head and slightly injured her scalp."—Lossing, 1851

Orgyia leucostigma, the White-marked tussock moth, is a moth in the family Lymantriidae. The caterpillar is very common especially in late summer in eastern North America, as far west as Texas, Colorado, and Alberta. There are two or more generations a year in eastern North America (Wagner 2005). They overwinter in the egg stage. Eggs are laid in a single mass over the cocoon of the female, and covered in a froth (Wagner 2005). Up to 300 eggs are laid at a time. he larvae are brightly coloured, with tufts of hair-like setae. The head is bright red, the body has yellow or white stripes, with a black stripe along the middle of the back. There are bright red defensive glands on the hind end of the back. Four white toothbrush-like tufts stand out from the back, and there is a grey-brown hair pencil at the hind end. Touching the hairs will set off an allergic reaction in many humans (Wagner 2005). Young larvae skeletonize the surface of the leaf, while older larvae eat everything except the larger veins (Rose and Lindquist, 1982). They grow to about 35 mm.

The chigoe flea (Tunga penetrans) is a parasitic arthropod found in tropical climates, especially South America and the West Indies. At 1 mm long, the chigoe flea is the smallest known flea. Breeding female chigoes burrow into exposed skin and lay eggs, causing intense irritation. After this point, the skin lesion looks like a 5 to 10 mm white spot with a central black dot, which are the flea's exposed hind legs, respiratory spiracles and reproductive organs.

They are small annual, biennial, or short-lived perennial herbaceous plants. The leaves are trifoliate (rarely 5- or 7-foliate), with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx

Coca is a plant in the family Erythroxylaceae, native to north-western South America. The plant plays a significant role in traditional Andean culture. Coca leaves contain cocaine alkaloids, a basis for the drug cocaine, which is a powerful stimulant. Coca should not be confused with the similarly named South American cocoa bean from which chocolate is made. The plant resembles a blackthorn bush, and grows to a height of 2&ndash;3 m (7&ndash;10 ft). The branches are straight, and the leaves, which have a green tint, are thin, opaque, oval, and taper at the extremities. A marked characteristic of the leaf is an areolated portion bounded by two longitudinal curved lines, one line on each side of the midrib, and more conspicuous on the under face of the leaf. The flowers are small, and disposed in little clusters on short stalks; the corolla is composed of five yellowish-white petals, the anthers are heart-shaped, and the pistil consists of three carpels united to form a three-chambered ovary. The flowers mature into red berries.
