"Spermatozoa of domestic cock, greatly magnified." The spermatozoam or seminal animalcules, or male Dynamamaebae (figs. 106, 107), are the exact counterparts of ovarian ova, in so far as they are single-celled animals of a very low grade of organization; but their activity and intelligence is marvelousm and still more so is the mysterious attribute with which they are endowed of assimilating their protoplasmic substance with that of the ovum; with the result that thus fecundated ovum is capable of procreating itself by fission for a period until a mass of similar creates in engendered; from which mass is then speedily evolved the complex body the bird."

"In England, as in Germany, architectural activity has assumed various phases in modern times. With few exceptions, the numerous newly-constructed churches are built in the Gothic style of the thirteenth and fourteenth centuries; whilst public secular buildings, for which a certain simplicity is appropriate, such as school and university buildings, asylums, &c., as well as large country-houses, are either constructed in the Pointed or in the Late Gothic, or so-called Perpendicular or Tudor style, with flat-arched, curved, or even horizontal heads to the openings. Other public buildings, as, for instance, the Houses of Parliament, which is the most important modern building in London, are carried out in this style. The Renaissance style has recently been frequently employed, especially for dwelling-houses."The Palace of Westminster, also known as the Houses of Parliament, is a complex of buildings in London. It is the seat of the two houses of the Parliament of the United Kingdom (the House of Lords and the House of Commons). The palace lies on the north bank of the River Thames in the London borough of the City of Westminster, close to the government buildings of Whitehall.

Robert Fulton, an American engineer and inventor, was the first to establish steam navigation. In 1800 he was commissioned by Napoleon Bonaparte to design the Nautilus, the first practical submarine in history. In 1806, Fulton married Chancellor Livingston's niece Harriet (who was the daughter of Walter Livingston), and they later had four children: Robert, Julia, Mary and Cornelia.In 1807, Fulton and Livingston together built the first commercial steamboat, the North River Steamboat (later known as the Clermont), which carried passengers between New York City and Albany, New York. The Clermont was able to make the 300 mile trip in 62 hours. From 1811 until his death in 1815, Fulton was a member of the Erie Canal Commission. He is buried in the Trinity Church Cemetery in New York City, alongside other famous Americans such as Alexander Hamilton.
