- Wright Brothers' Wind tunnel
They found that a slight curve or camber in the wing section would cause the moving air to travel farther over the top of the wing surface than along the under side. This made the air pressure greater under the wing, gave a suction effect above the wing, and caused it to rise, creating lift. They discovered that a wing section of the proper camber would counteract the weight of gravity. Thus, a wing must be so designed that, with a certain amount of air flowing around it, it would lift a certain weight. They also discovered that air flow against any surface attached to the wing would cause a resistance or drag. Hundreds of experiments in their wind tunnel with various types of wing shapes gave the Wrights a series of tables from which to design a wing that would create the lift for a designed weight. - Wright Brothers' Bicycle shop
Out in Dayton, Ohio, there were two small brothers, who dreamed, as countless other children before them had dreamed, of flying like birds through the air. Their dreams were heightened by a small toy given to them by their father, the pastor of a local church. This toy was to lead to an idea which had a profound effect on the world. You would probably call it a flying propeller. It consisted of a wooden propeller which slipped over a notched stick. By placing a finger against the propeller and rapidly pushing it up the notched stick, the propeller was made to whirl up off the end of the stick and fly into the air. The brothers, young as they were, never quite forgot this little toy as they continued to dream of flying like birds through the air. Though the brothers continued to dream of flying, they were not the kind of lads who spent all their time in dreaming. They made kites which flew a little better and a little higher than those made by the other boys in the neighborhood. They built a press to print their own little newspaper, and they dabbled in woodcuts. To carve out porch posts for their father’s home they built an eight-foot wood-turning lathe. Indeed, they were the sort of boys who caused the neighbors to say, “What will they think of next?” The brothers knew that if they ever wanted to see their dreams come true they must earn their own capital. In the early nineties America was in the midst of the bicycle craze. Everyone who could possibly afford to do so owned a bicycle of some sort and belonged to a cycle club. Being mechanically minded, the brothers did the logical thing. They set themselves up in a small bicycle shop in Dayton, next door to their home. The bicycle shop in Dayton prospered, for the brothers were careful and expert mechanics, and cyclists in need of repairs made their way to the Wright Brothers’ shop. - Wright Brothers first powered airplane
By 1903 the Wright Brothers were ready to build a powered man-carrying flying machine. Their experiments had shown them just how much moving air was necessary to create lift in such a machine. To create the needed thrust, an engine having eight horsepower and weighing not over 200 pounds had to be fitted into the machine. Such an engine was not available, so the Wrights built one in their shop at Dayton, Ohio. They were ready to ship their airplane to Kitty Hawk, N. C., in the fall of 1903. - Wright Brotherrs wind tunnel
The Wright Brothers were not only inspired mechanics (as many people still believe today) but serious scientists, working along the soundest lines. In their keen desire to know what air pressure on wings really was, they cleared a corner of their bicycle shop and built a small wind tunnel with spare lumber and an old electric fan. They built small wing sections of various shapes and experimented with them in their wind tunnel. The electric fan was used to create the moving air around the wing section. By attaching the wing sections to a supporting frame and connecting the frame with a pointer and dial, they were able to keep a record of the effect of moving air on each experimental wing section. Through their wind tunnel research the Wright Brothers discovered the four forces that control all heavier-than-air flight: lift, thrust, weight, and drag. - Woolly mammoth

There are no people existing, who pay so sacred an attention to the laws of decency as the Chinese ; habituated in preserving the constant appearance of modesty and self -controul, nothing is more uncommon amongst them, than deleterious examples of unblushing vice ; and if there be truth in the old maxim , that want of decency, either in action , or in word, betrays a deficiency of understanding, they certainly indicate more sense than some other nations , who affect to excel them in education and refinement. The general manners of people of every condition in China wear as modest a habit, as their persons. They discover no gratification in wresting their proper language into impure meanings; and grossly offensive phrases are only to be heard amongst the very dregs of the community, and at the risk of immediate and severe judicial correction . - Title frame

Throw to first - The Wright Brothers experimental glider
After a year of exhaustive study and experiments with models in their wind tunnel, the Wright Brothers were ready to experiment with a man-carrying glider. With the thoroughness that was typical of every move of the Wrights, the brothers asked the government to let them have information on meteorological conditions all over the country. By studying the weather charts they were able to find a locality where there was a continual flow of wind. This would be nature’s wind tunnel where they could test their glider day after day. Through their study of the charts they found that the wind conditions at Kitty Hawk, on the North Carolina coast, seemed to offer the best possibilities for their glider test. Orville and Wilbur Wright began their experiments with a small man-carrying glider at Kitty Hawk in 1900. From that time until 1903 they made hundreds of successful glider flights and kept accurate records of each flight. They recorded wind velocity, angle of flight, duration of flight, time of day, temperature, humidity, and sky conditions overhead with the typical Wright attention to detail. Each year the Wrights constructed new gliders which embodied principles they had discovered for themselves during their flights at Kitty Hawk. Each glider was larger and had longer and narrower wings than the one before. During the fall of 1902 the brothers recorded nearly a thousand flights in a glider with a wingspan of thirty-two feet. It had a front elevator and a vertical tail which helped to maintain lateral stability. - The Umpire
The Umpire - The seven herbs of autumn
People go out at this time to look at the Seven Herbs of Autumn, the principal of which is the lespedeza bicolor with its pretty little red flowers; the other six are the miscanthus sinensis, pueraria thunbergiana, dianthus superbus, patrinia seabiosœfolia, cupatorium chinense, and platycodon grandiflorum. The autumnal equinox is celebrated in the same manner as the vernal. - The Rack
This horrible engine of barbarity and error is not peculiar to Roman Catholic countries, it is used even in China , for the purpose of extorting confession . The method of employing it, in torturing the ankles, is exhibited in this Plate . The instrument is composed of a thick , strong plank, having a contrivance at one end to secure the hands, and at the other a sort of double wooden vice . The vice is formed of three stout uprights, two of which are moveable, but steadied by a block , that is fastened on each side. The ankles of the culprit being placed in the machine, a cord is passed round the uprights, and held fast by two men . The chief tormentor then gradually introduces a wedge into the intervals , alternately changing sides . This method of forcing an expansion at the upper part, causes the lower ends to draw towards the central upright , which is fixed into the plank , and thereby compresses the ankles of the wretched sufferer ; who, provided he be fortified by innocence, or by resolution, endures the advances of the wedge, until his bones are completely reduced to a jelly. - The Manner of Beheading
This sort of punishment, being deemed in the highest degree ignominious , is only inflicted for crimes, which are regarded by the Chinese government, as the most prejudicial to society ; such as conspiracy,assassination , committing any offence against the person of the Emperor, or attempting the life of any of the imperial family ; revolting, insurrection , striking a parent, or any other unnatural sort of crime. The malefactor, who is condemned to be beheaded, is made to kneel upon the ground, the board of infamy is taken from his back, and the executioner, by a single blow of a two - handed sword, strikes off his head with great dexterity. These headsmen , and indeed, the generality of inferior officers of justice in China, are selected from the soldiery, according to the custom of primitive barbarians ; neither is this employment considered more ignominious, than the post of principal officer of executive justice in other countries . Decapitation is held, by the Chinese, as the most disgraceful kind of death ; because the head, which is the principal part of a man , is separated from the body, and that body is not consigned to the grave as entire as he received it from his parents .. If a great mandarin be convicted of any atrocious offence, he is executed in this manner like the meanest person . After the head is severed , it is frequently suspended from a tree, by the side of a public road ; the body is thrown into a ditch , the law having deemed it unworthy the respect of regular funereal rites . When a sentence is submitted to the Emperor for his approbation, if the crime be of the first degree of atrocity , he orders the malefactor to be executed without delay ; when it is only of an ordinary nature, he directs, that the criminal shall be imprisoned until the autumn, and then executed ; a particular day of that season being allotted for such ceremonies. The Emperor of China seldom orders a subject to be executed , until he has consulted with his first law officers, whether he can avoid it, with out infringing on the constitution of his realm . He fasts for a certain period, previous to signing an order for an execution ; and his imperial majesty esteems those years of his reign the most illustrious and most fortunate , in which he has had the least occasion to let fall upon his subjects the rigorous sword of justice. - The Manager of the team

The outer ditch of the place, also the town ditch, commenced in a deep ravine close north of the keep, and was carried along the north front, skirting what are called “the Flats”; thence along the east front, between the wall and the town, and thence round the south end, and so beneath a part of the west front, until it is lost in the steep ground near the bridge, having been altogether nearly 700 yards in length. - The Four forces of flight
after testing more than 200 wing designs and plane surfaces in their wind tunnel, the Wright Brothers found out how to figure correctly the amount of curve, or camber, that was essential to weight-carrying wings. They discovered, too, that before man could be flown through the air, he must have his wings attached firmly to a body or platform which was firm and controllable. The Wrights in their earliest experiments had realized that to be practical their machine must be built not only to fly in a straight line, but also in order that it could be steered to the right or to the left. One day, Orville was twisting a cardboard box in his hand when Wilbur noticed it. Immediately he saw the solution to the problem of steering their airplane. The result was a design which changed the lift of either end of the wing by warping its surface. If one end of the wing was warped to give it more lift, the machine would lift on that side and fall off into a turn. Thus the problem of steering was solved by the Wrights - The flight of Etana
Historians have unearthed stories in cuneiform writing of man’s attempts to fly. Some of these inscriptions date back more than five thousand years, to 3500 B.C. Perhaps the most famous of these stories is the ancient Babylonian tale of the shepherd boy, Etana, who rode on the back of an eagle. - The flag Major Anderson carried with him from Fort Sumter

The Crowd went wild - The capital Punishment of the Cord
The usual capital punishments in China are strangling, and beheading. The former is the most common , and is decreed against those, who are found guilty of crimes, which , however capital, are only held in the second `rank` of atrocity. For instance, all acts of homicide, whether intentional or accidental; every species of fraud, committed upon government : the seduction of a woman, whether married or single; giving abusive language to a parent, plundering or defacing a burying place ; robbing with destructive weapons : and for wearing pearls. It would not, perhaps, be possible to form any probable conjecture of the motive, which has induced the Chinese legislators to attach the pain of death to the wearing of a precious gem . The fact is, therefore, only stated from the information of various writers, and remains to be explained by some future commentator. Criminals are sometimes strangled with a bow -string, but on general occasions, a cord is made use of, which fastens the person to a cross, and one turn being taken round his neck , it is drawn tight by an athletic executioner. Men of distinction ,are usually strangled, as the more honourable death ; and where the Emperor is inclined to shew an extraordinary mark of attention towards a mandarin , condemned to die, he sends him a silken cord, with permission to be his own executioner . - The Aerodrome
Langley built his plane without much difficulty, but could not find anyone to make an engine large enough for it. Finally, Charles Manley, an expert engineer, asked for permission to build the engine. Manley’s engine was a five-cylinder, radial gasoline engine that developed 51 horsepower and was far ahead of its time. It was years before American radial engines were used successfully in airplanes. Professor Langley called his machine the Aerodrome, and by October, 1903, the plane was ready for its test flight, with Manley to guide it. The Aerodrome was to be launched from a catapulting platform built on the roof of a houseboat. The houseboat was anchored on the Potomac River near Washington. As it left the platform the machine crashed into the river, and the trial was a dismal failure. The newspapers and the public ridiculed Langley, but he and Manley, who was unhurt in the crash, repaired the machine for another trial. This test took place on December 8, 1903, and again the Aerodrome crashed into the river. Manley once more escaped injury, but Langley and the government were abused by the public for wasting money. Langley was out of money himself, the government could not furnish funds for further trials, so the experiments were ended. The professor, discouraged and brokenhearted, gave up. - Swing and a miss

This punishment is deemed very disgraceful. The collar is formed of heavy pieces of wood, closed together, and having a hole in the centre, which fits the neck of the offender, who, when this machine is upon him, can neither see his own feet, nor put his hands to his mouth . He is not permitted to reside in any habitation , nor even to take rest for any considerable length of time, an inferior officer of justice constantly attending, to prevent him. By night and by day, he carries this load , which is heavier or lighter, according to the nature of the crime, and the strength of the wearer. The weight of the common sort of these wooden collars , is only fifty or sixty pounds, but there are those, which weigh two hundred, and which are so grievous to the bearers that sometimes , through shame, pain , want of proper nourishment, or of natural rest, they have been known to expire under them . The criminals find various methods, however, of mitigating this punishment: by walking in company with their relations and friends, who support the corners of the collar, and prevent it from pressing upon the shoulders ; by resting it upon a table , a bench , or against a tree; or, according to the representation in the accompanying Plate, by having chair constructed for the purpose, with four posts of equal heights to support the machine. When this ponderous incumbrance is fixed upon an offender, it is always before the magistrate, who has decreed it ; and upon each side, over the places where the wood is joined , long slips of paper are pasted, upon which the name of the person , the crime, which he has committed, and the duration of his punishment, are written, in very distinct characters ; a seal is likewise stamped upon the paper, to prevent the instrument from being opened . Three months is the usual time appointed for those to bear about this collar, who have been convicted of robbery. For defamation, gambling, or breaches of the peace ,it is carried a few weeks ; and insolvent debtors are sometimes ordered to bear it, until they have satisfied their creditors . When the offender is to be liberated from the collar, it must be in the presence of the magistrate, who has imposed it ; he then generally orders him a few blows of the pan-tsee, and dismisses him, with an exhortation to comport himself more regularly in future . Near the figure in this Engraving, are represented the basin and the sort of spoon , by which persons in that situation are supplied with food. - Punishment of the Swin
This man is suspended by his shoulders and ankles, in a very painful situation : at intervals, two attending officers afford some trifling alleviation of his sufferings, by supporting him with a bamboo, passed under his breast. Pencil, ink, and paper, are ready, to note down whatever he may say. This punishment, together with the preceding one, is chiefly inflicted upon such merchants as have been detected in committing frauds, impositions, or any other unwarrantable tricks of trade. - Punishment of a Woooden Tube
A piece ofbamboo cane is provided, which nearly corresponds with the height of the criminal, and is of considerable circumference. This bamboo being perfectly hollow , admits the passage of a large iron chain, one end of which is rivetted round a stake, the other encircles his neck, and is confined there by a padlock. His legs are fettered by a few links of chain. - Punishing an Interpreter
A large piece of bamboo cane is placed behind his knees; this is trampled on by two men, one standing on each end, and who convey more or less pain, as they approach to, or recee from, his person. A punishment, decreed against interpreters, detected of wilful misinterpretation. - Punishing a Boatman
A species of correction appointed for boatmen, or, as they are termed in England, watermen . Having been convicted of some misbehaviour, he is compelled to kneel : one of the officers of justice prevents him from flinching, whilst another grasps his hair, and bestows a certain number of blows upon each side of his face, with a sort of double battledore, made of thick leather. - Protea abyssinica

ARQUES is one of the earliest examples of a Norman castle, for which reason, though not an English fortress, it has been thought convenient to include an account of it in these pages. This grand castle crowns and occupies the head of a steep and bold cape or promontory, in this case a spur from the great chalk table-land of the “Pays de Caux.” On the west it is flanked by a short but deep combe or dry valley, and on the east by the deeper and far wider valley of the Bethune and Varenne—streams derived from different sources, but which here meander across a broad and level bottom, above half a mile wide, until, a little below the castle, uniting, they receive the tributary Aulne, and, thus combined, under the name of “la Rivière d’Arques,” fall into the sea at the port of Dieppe.

It is about five miles from, and about 200 feet above, the sea-level. Towards the east and south the castle is cut off from the town of Alnwick by a deep combe, once the bed of the Bow Burn. This has been trimmed and scarped by art, and its upper part towards the town has been almost obliterated by modern upfilling. 1. Donjon. 2. Inner Ward. 3. Outer Ward. 4. Terrace. 5.

In Opostomias micripnus, a dark black fish living at a depth of over 2,000 fathoms, there are two rows of ocellar organs running down the sides of the body from the head to the tail. In the living animal they are said to shine with a reddish lustre. In addition to these, the conspicuous organs, there are `groups` of fifty, a hundred, or even more very much smaller organs situated on the sides and back of the fish, each of which is lenticular in shape and consists of a number of short polygonal tubes containing a granular substance with rounded bases resting on the subjacent tissue. The whole organ is covered 79by a simple continuation of the cuticle of the body-wall. The granular substance contained in the tubes is most probably the seat of luminosity. - Octave Chanute experimenting with his gliders on the Michigan sand dunes
Octave Chanute, born in France and reared in America, was one of the first men to make a scientific approach to the problem of flying machines. A thorough scientist, he had followed the progress of all flight experiments the world over. He built gliders with one, two, and even five pairs of wings and tested all of them on the sand dunes of Lake Michigan. His most successful glides were made with a biplane glider. In 1894, he published a book called Progress of Flying Machines, which covered all the efforts of men like himself who had experimented with man-carrying gliders and flying machines. - Nymphaea stellata

Mr. Higginson’s Transfusion Instrument Although some of the early experiments on blood transfusion had been done in England, and although its revival [14]in the nineteenth century was initiated in England, yet it is to be noticed that most of the references to it up to 1874 are to be found in the works of Continental writers. Nevertheless, an important modification was introduced into the technique of the operation in 1857 by Higginson, who applied the principle of a rubber syringe with ball-valves for transferring the blood from the receptacle into which it was drawn, to the vein of the recipient. This apparatus is illustrated here, as it is of some interest in the history of medicine. A is a metallic cup, of 6-oz. capacity, to receive the supply of blood. B an outer casing, which will hold 5 oz. of hot water, introduced through an aperture at C. D is a passage leading into an elastic barrel, composed of vulcanized india-rubber, E, of which the capacity is 1 oz. F′ the exit for the blood into the injection-pipe G. At D and F there are ball-valves, capable of closing the upper openings when thrown up against them, but leaving the lower openings always free. The blood, or other fluid, poured into the cup A, has free power to run unobstructed through D, E, F; a small plug H is therefore provided to close the lower aperture F when necessary. The tube G is of vulcanized india-rubber, and terminates in a metal tube O for insertion into the vein. - Moraea iridioides
