Eton College was founded in 1440 by Henry VI as a charity school to provide free education to seventy poor boys who would then go on to King's College, Cambridge, a constituent college of the University of Cambridge, which he also founded in 1441. This was a copy of William of Wykeham's link between Winchester College and New College, Oxford. Henry VI took half the scholars and the headmaster from William of Wykeham's Winchester College (founded 1382). Eton was modelled on Winchester College, and became popular in the 17th century.

Martin Luther (November 10, 1483 - February 18, 1546) was a German monk, theologian, university professor, Father of Protestantism, and church reformer whose ideas influenced the Protestant Reformation and changed the course of Western civilization. Luther's theology challenged the authority of the papacy by holding that the Bible is the only infallible source of religious authority and that all baptized Christians under Jesus are a universal priesthood. According to Luther, salvation is a free gift of God, received only by true repentance and faith in Jesus as the Messiah, a faith given by God and unmediated by the church.

An illustration of a Florida Cracker. Florida Cracker refers to the original colonial era American pioneer settlers of the State of Florida. The first Florida Crackers arrived in 1763 when Spain traded Florida to Great Britain. The British divided the territory into East Florida and West Florida, and began to aggressively recruit settlers to the area, offering free land and financial backing for export-oriented business.

Diagram to illustrate the development of a tooth. I. Shows the downgrowth of the dental lamina D.L. from the surface epithelium E and the beginning of the enamel germ E.G. II. Shows the further growth of the enamel germ and its invagination. III. The enamel germ is more invaginated, and its inner layer of cells becomes columnar. A, the dental lamina, grows thinner, but near its posterior or lingual edge there is an enlargement R.G which is the reserve germ for a permanent tooth. The superficial cells of the dentine papilla P are becoming columnar. IV. The inner columnar cells of the enamel germ ( called enamel cells) A have formed a cap of enamel EN, inside which the superficial cells of the papilla, the odontoblasts O, have formed a layer of dentine D. V. Shows a more advances stage still. The deposit of dentine is extending downwards, and enclosing the papilla to form the future pulp, in which a vessel V is seen. Labels: A, inner layer; B, outer layer; C, remains of intermediate cells; D, dentine; D.L, dental lamina; E, epithelium; E.G, enamel germ; EN, enamel; F, dental furrow; L.D, labio-dental furrow; M, connective tissue cells; O, odontoblasts; P, dentine papilla; R.G, reserve germ; V, blood vessels.

Fernando Wood (June 14, 1812 – February 14, 1881) is famous for being one of the most colorful mayors in the history of New York. He was chairman of the chief young men's political organization in 1839 and was a member of the Tammany Society, which he used as a vehicle for his political rise. Wood served as Mayor of New York from 1855 to 1862. During this time a police feud developed between the New York Municipal Police and the Metropolitan Police Force. This feud led to increased gang activity due to the police rivaling one another rather than upholding the law. Wood was one of many New York Democrats sympathetic to the Confederacy, called 'Copperheads' by the staunch Unionists. In January 1861, Wood suggested to the City Council that New York secede and declare itself a free city.

An illustration of a small jellyfish. Jellyfish are free-swimming members of the phylum Cnidaria. ellyfish don't have specialized digestive, osmoregulatory, central nervous, respiratory, or circulatory systems. They digest using the gastrodermal lining of the gastrovascular cavity, where nutrients are absorbed. They do not need a respiratory system since their skin is thin enough that the body is oxygenated by diffusion. They have limited control over movement and mostly free-float, but can use the hydrostatic skeleton of the water pouch to accomplish vertical movement through pulsations of the disc-like body.

A pillar is similar to a column which is a vertical support structure in architecture, but the base section is any shape but circular. Tschultri, or choultry, is a resting place for visitors where rooms and food are provided by a charitable institution for nominal rates. Some were guest-houses where accommodation is free of charge. Choultries were famous in Colonial India. It was an Hindu-Caravanserai or a Colonnade. It was a typical ancient Indian type of hotel.
