"Right pectoral arch of a bird. s, scapula; c, coracoid; gl, glenoid, the cavity for head of humerus; cl, clavicle; hc, hypecleidium. In situ, the right end of the figure should tilt up a little.The pectoral arch is that bony structure by which the wings are borne upon the axial skeleton. It is to the fore limb what the pelvic arch is to the hind limb; but is disconnected from the back-bone and united with the breastbone, whereas the reverse arrangement obtains in the pelvic, which is fused with the sacral region of the spine. Each pectoral arch of birds consists (chiefly) of three bones: the scapula and coracoid, forming the shoulder-girdle proper, or scapular arch; and the accessory clavicles, or right and left half of the clavicular arch." Elliot Coues, 1884

The Common Mudpuppy (Necturus maculosus) is a species of aquatic salamander found throughout the northeastern United States, and parts of Canada. Mudpuppies prefer shallow water with many places to hide, but have been found at depths of up to 90 feet. The mating season is late autumn, however eggs are not laid until late spring when 50 to 100 eggs are deposited in a nest cavity under a rock or other object. It takes 1 to 2 months for the eggs to hatch and 4 to 6 years for the young to reach maturity. Mudpuppies may live for up to 20 years.

Male, in breeding plumage: Black; cervix buff; scapulars, rump and upper tail-coverts ashy-white; interscapulars streaked with black, buff, and ashy; outer quills edged with yellowish; bill blackish-horn; feet brown. The faultless full dress of black, white, and buff is worn only for a brief period; and even in spring and summer, most males are found to have yellowish touches in the black, especially of the under parts. The "delirious song" is only heard while the males re trooping their way to their breeding-grounds, and before the midsummer change of feather." Elliot Coues, 1884

"A certain originality and freedom of intervention is perceptible in the buildings of the early period of the Venetian Renaissance style; the old style is happily blended with the new, which during the first stage is still imbued with Romanesque conceptions."The Vendramin were a rich merchant family of Venice, Italy. What is now the most prominent "Palazzo Vendramin" in Venice, the splendid Ca' Vendramin Calergi by Mauro Codussi on the Grand Canal, was in fact only inherited by the family in 1739, and is now the casino, also famous as the place where Richard Wagner died in 1883. Some rooms are kept as a museum commemorating Wagner's stay. The 16th century Ca' Vendramin di Santa Fosca in the Cannaregio quarter, now also a hotel, is where Gabriele Vendramin's collection was housed. Yet another is the 16th or possibly 17th century "Palazzo Vendramin dei Carmini", in Dorsoduro, most of which is now occupied by part of the University of Venice.

The Panthéon (Latin Pantheon, from Greek Pantheon, meaning "Every god") is a building in the Latin Quarter in Paris, France. It was originally built as a church dedicated to St. Genevieve, but after many changes now combines liturgical functions with its role as a famous burial place. It is an early example of Neoclassicism, with a façade modeled on the Pantheon in Rome, surmounted by a small dome that owes some of its character to Bramante's "Tempietto". Located in the 5th arrondissement on the Montagne Sainte-Geneviève, the Panthéon looks out over all of Paris. Its architect, Jacques-Germain Soufflot, had the intention of combining the lightness and brightness of the gothic cathedral with classical principles. Soufflot died before his work was achieved, and his plans were not entirely followed. The transparency he had planned for his masterpiece was not attained. Nevertheless, it is one of the most important architectural achievements of its time and the first great neoclassical monument."Toward the end of the reign of Louis XV. a reaction set in, which was caused partly by the excess and caprice displayed in the application of this style, and partly by the tide again setting in the direction of the antique. This evidence by the Colonnades de la Place de Concorde, and by the Church of Ste. Geneviève, which was begun by Soufflot in the year 1755, and subsequently received the name of Pantheon [shown here]. From thenceforth imitations of ancient buildings came into vogue, as they also did in other countries."

The Palazzo Pitti, in English sometimes called the Pitti Palace, is a vast mainly Renaissance palace in Florence, Italy. It is situated on the south side of the River Arno, a short distance from the Ponte Vecchio. The core of the present palazzo dates from 1458 and was originally the town residence of Luca Pitti, an ambitious Florentine banker.The palace was bought by the Medici family in 1549 and became the chief residence of the ruling families of the Grand Duchy of Tuscany. It grew as a great treasure house as later generations amassed paintings, plates, jewelry and luxurious possessions.In the late 18th century, the palazzo was used as a power base by Napoleon, and later served for a brief period as the principal royal palace of the newly united Italy. The palace and its contents were donated to the Italian people by King Victor Emmanuel III in 1919, and its doors were opened to the public as one of Florence's largest art galleries. Today, it houses several minor collections in addition to those of the Medici family, and is fully open to the public."Columns, pilasters, and mouldings are intermingled and intertwined in a fantastic and meaningless manner, the cornices are often interrupted; the essentially component parts of the architecture are frequently mutilated; for instance, columns and wall-pilasters are executed in rustic work, i. e., formed of extensively projecting hewn stones, yet are furnished with a capital and base as is shown [in this image], which is an illustration taken from the Late Italian Renaissance. For the sake of peculiarity, the various component elements assumed a form diametrically opposed to their original designation; mere decorative and secondary details were raised to the rank of essentials, whilst the real principal forms sank to an entirely subordinate position."

In the "bound-palate" type, the vomer in either abortive, or so small that it disappears; when existing it is usually slender and tapers to a point in front; the maxillo-palatines are united across the median line, either directly or by means of ossification in the nasal septum; the posterior ends of the palatines and the anterior ends of the pterygoids articulate directly with the rostrum (as in schizognathism). This type is simply and perfectly exhibited by a duck in which the maxillo-palatine is a broad flat plate united with its fellow in mid-line; the oval sessile basipterygoid facets are far forward, opposite the very ends of the pterygoids."

"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.

A can opener is a device used to open metal cans. Although preservation of food using tin cans had been practiced since at least 1772 in the Netherlands, the first can openers were patented only in 1855 in England and in 1858 in the United States. Those openers were basically variations of a knife, and the 1855 design continues to be produced. The first opener employing the now familiar sharp rotating wheel, which runs around the can's rim cutting the lid, was invented in 1870 but was difficult to operate. A breakthrough came in 1925 when a second, serrated wheel was added to hold the cutting wheel on the rim of the can. This easy to use design has become one of the most popular can opener models.
