"A ball-bearing hub with outward cups. The hub-shell H is turned out of mild steel, and the cups C are forced into the ends of the hub-shell and soldered thereto. A thin washer W is then spun into the end, for the purpose of retaining oil, and a thin internal tube T unites the two cups, and guides the oil fed in at the middle of the hub to the balls. The projecting flanges S are for the attachment of the tangent spokes used to build the hub into the wheel. The spindle A has the two cones screwed on it, one C, against the shoulder, the other C, adjustable. The-spindle ends are passed through the back-fork ends and are there adjusted in position by the chain-tension adjusters. After adjustments the nuts N clamp the spindle securely between the fork-ends. The chain-wheel or free-wheel clutch is screwed on the end of the hub-shell with a right-hand thread." — The Encyclopedia Britannica, 1910

"The usual form of crank-axle bearing which has inward-cups and is cup-adjusting. The end of the bracket is split and the cup after adjustment is clamped in position by the clamping screw S. The usual mode of fastening the cranks to the axle is by round cotters C with a flat surface at a slight angle to the axis, thus forming a wedge, which is driven in tight. The small end of the cotter projects through the crank, and is screwed and held in place by a nut. The chain-wheel at the crank-axis is usually detachable fastened to the right-hand crank." — The Encyclopedia Britannica, 1910

"Windlass.—The common windlass for drawing water is another modification of the wheel and axle. The winch, or crank, by which it is turned, is moved around by the hand, and there is no difference in the principle, whether a whole wheel is turned, or a single spoke. The winch, therefore, answers to the wheel, while the rope is taken up, and the weight raised by the axle, as already described." —Comstock, 1850

"The whole length of the tube of the wheel barometer, from C to A, is 34 or 35 inches, and it is filled with mercury, as usual. The mercury rises in the short leg to the point a, where there is a small piece of glass floating on its surface, to which there is attached a silk string, passing over the pulley p. To the axis of the pulley is fixed an index, or hand, and behind this is a graduated circle, as seen in the figure. It is obvious, that a very slight variation in the height of the mercury at o, will be indicated by a considerable motion of the index, and thus changes in the weight of the atmosphere, hardly perceptible by the common barometer, will become quite apparent by this." —Comstock, 1850

"The middle one an ordinary hook tool, suited for outside work on wrought iron or steel, and the one above it a left hand tool which can be used also for inside. Their cutting edges are of course forged and ground straighter or more pointed or otherwise varied according to circumstances, and for cast iron or brass the angle of the edge is made much less acute, as in the lowest of the three in the engaving." —The Encyclopedia Britannica, 1903

"The machine is in fact a lathe with a few special features, such as the hollow mandrel, which enables it to operate upon a bar of any length. Dies mounted on a modified form of slide-rest cut the thread to the full depth at a single traverse, and a simple arrangement enables nuts to be tapped with equal facility. In some other varieties of screwing machines, more particularly those intended for hand power only, the outward resemblance to the turning lathe is less apparent, but if their action is looked into it will be found that in them as in almost all machine tools it is the principle of the slide which is mainly conducive to their success." —The Encyclopedia Britannica, 1903

"An ordinary vertical drilling machine, one of comparatively small size and single-geared having been chosen rather than a larger example with greater complication. When once properly started, this machine is self-acting, but for each hole the work has to be adjusted by hand so as to bring the required portion exactly under the drill spindle, and the small size of the table prevents its being at any great distance from the edge." —The Encyclopedia Britannica, 1903

"Probably no other insect has been the subject of so many and widespread legends and superstitions as the common "praying mantis," Mantis religiosa. The ancient Greeks endowed it with supernatural powers; the Turks and Arabs hold that it prays constantly with its face turned towards the mecca; the Provencals call it Prega-Diou; and numerous more or less similar names —preacher, saint, nun, medicant, soothsayer, etc., widely diffused throughout southern Europe. Children ask it to show them the way, and Mouffet assures us that it rarely or never deceives them; and it is even recorded that one specimen, which aligted on the hand of St. Francis Xavier, and which he commanded to sing the praise of God, loudly intoned a very beautiful canticle." —The Encyclopedia Britannica, 1903

A decorated shield rest on his left hip and a cape rests on his shoulders. His hair is in long braids and his helmet is tall and pointed, resembling a crown. His sandals wrap around his leg up to his knee.

As a kind of joke, John, King Henry's youngest son, had been called Lackland, because he had nothing when his brothers each had some great dukedom. The name suited him only too well before the end of his life. The English made him king at once. Richard had never had any children, but his brother Geoffery, who was older than John had left a son named Arthur, who was about twelve years old, and who rightly the Duke of Normandy and Count of Anjou. King Philip, who was always glad to vex whoever was king of England, took Arthur under his protection, and promised to get Normandy out of John's hands. However, John had a meeting with him and persuaded him to desert Arthur, and marry his son Louis to John's own niece, Blanche, who had a chance of being queen of part of Spain. Still Arthur lived at the French King's court, and when he was sixteen years old, Philip helped him to raise an army and go to try his fortune against his uncle. He laid siege to Mirabeau, a town where his grandmother, Queen Eleanor, was living. John, who was then in Normandy, hurried to her rescue, beat Arthur's army, made him prisoner and carried him off, first to Romen, and then to the strong castle of Falaise. Nobody quite knows what was done to him there. The governor, Hubert de Burgh, once found him fighting hard, though with no weapon but a stool, to defend himself from some ruffians who had been sent to put out his eyes. Hubert saved him from these men, but shortly after this good man was sent elsewhere by the king, and John came himself to Falaise. Arthur was never seen alive again, and it is believed that John took him out in a boat in the river at night, stabbed him with his own hand, and threw his body in the river.

Wat Tyler, while talking to the King, grew violent, forgot to whom he was speaking, and laid his hand on the king's bridle, as if to threaten or take him prisoner. Upon this, the Lord Mayor, with his mace-dealt the man such a blow that he fell from his horse, and an attendant thrust him through with a sword.

Edward VI became King of England and Ireland on January 28, 1547, at just nine years of age. Edward, the son of Henry VIII and Jane Seymour, was the third monarch of the Tudor dynasty and England's first ruler who was Protestant at the time of his ascension to the throne. Edward's entire rule was mediated through a council of regency as he never reached majority. The council was first led by his uncle, Edward Seymour, and then by John Dudley.

"And they came to the place which God had told him of. And Abraham built the altar there, and laid the wood in order, and bound Isaac his son, and laid him on the altar, upon the wood. And Abraham stretched forth his hand, and took the knife to slay his son. And the angel of Jehovah called unto him out of heaven, and said, Abraham, Abraham. And he said, Here I am. And he said, Lay not thy hand upon the lad, neither do thou anything unto him. For now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son, from me." Genesis 22:9-12 <p>This sculpture is a Bronze-relief by Brunellesco. There is a similar sculpture done by Ghiberti. It can now be found in the National Museum in Florence, Italy.
