A game of doubles in lawn tennis - A Ganglion of a Leech
Pear-shaped cells are set round a felt-work of nerve-fibrils (neuropil). A neuro-sensory cell is shown with one fibre directed peripherally, branching on the surface; and one directed centrally, ramifying in the neuropil. Several very slender fibrils from the neuropil pass up the stalk of each ganglion-cell. They join a network near its surface. This net is connected by radiating fibrils with a coarser net which surrounds the nucleus. From the central net a relatively stout fibril passes to muscle-fibres. - A heavy net is useful to capture aquarium specimens

A chicken coop for grown fowls can be of almost any shape, size, or material, providing that we do not crowd it to more than its proper capacity. The important thing is to have a coop that is dry, easily cleaned and with good ventilation, but without cracks to admit draughts. A roost made of two by four timbers set on edge with the sharp corners rounded off is better than a round perch. No matter how many roosts we provide, our chickens will always fight and quarrel to occupy the top one. Under the roost build a movable board or shelf which may easily be taken out and cleaned. Place the nest boxes under this board, close to the ground. One nest for four hens is a fair allowance. Hens prefer to nest in a dark place if possible. A modern, up-to-date coop should have a warm, windproof sleeping room and an outside scratching shed. A sleeping room should be provided with a window on the south side and reaching nearly to the floor. - A home-made rabbit house
A rabbit hutch or coop is easily built from old packing boxes. One third of the coop should be darkened and made into a nest, with an entrance door outside and the rest simply covered with a wire front, also with a door for cleaning and feeding. The hutch should stand on legs above ground as rabbits do not thrive well in dampness. They will, however, live out all winter in a dry place. A box four feet long and two feet wide will hold a pair of rabbits nicely. Rabbits will become very tame and may often be allowed full liberty about the place if there are no dogs to molest them. The drawing shows a standard type of rabbit hutch. A boy who is handy with tools can easily build one. We can always dispose of the increase in our rabbit family to friends or to dealers. - A landing net should be a part of every fisherman's outfit
A landing net should be a part of every fishing outfit. More fish are lost just as they are about to be lifted from the water than at any other time. A gaff is used for this same purpose with fish too large to go into a landing net. A gaff is a large hook without a barb fastened into a short pole. If you have no net or gaff and have succeeded in bringing a large fish up alongside the boat, try to reach under him and get a firm grip in his gills before you lift him on board. If it is a pickerel, look out for his needle-like teeth. - A Minute Portion of the Pulp of the Spleen
A Minute Portion of the Pulp of the Spleen,very highly magnified. Stellate connective-tissue cells form spaces containing red blood-corpuscles and leucocytes. In the centre of the diagram is shown the mode of origin of a venule. It contains two phagocytes—the upper with a nucleus, two blood-corpuscles just ingested, and one partially digested in its body-substance; the lower with two blood-corpuscles. - A reflector camp oven
There are several kinds of ovens used for baking bread and roasting meat in outdoor life. The simplest way is to prop a frying pan up in front of the fire. This is not the best way but you will have to do it if you are travelling light. A reflector, when made of sheet iron or aluminum is the best camp oven. Tin is not so satisfactory because it will not reflect the heat equally. Both the top and bottom of the reflector oven are on a slope and midway between is a steel baking pan held in place by grooves. This oven can be moved about at will to regulate the amount of heat and furthermore it can be used in front of a blazing fire without waiting for a bed of coals. Such a rig can easily be made by any tinsmith. A very convenient folding reflector oven can be bought in aluminum for three or four dollars. When not used for baking, it makes an excellent dishpan. - A Section approximately at Right Angles to the Long Axis of the Heart
A Section approximately at Right Angles to the Long Axis of the Heart, exposing the Four Valves which lie very nearly in the Same Plane. The semilunar valve which guards the aperture of the pulmonary artery is the nearest to the breast-bone. - A self-sustaining or balanced aquarium
three children looking at an aquarium Any transparent vessel capable of holding water, even a Mason jar will make an aquarium from which a great deal of pleasure may be derived. The old way of maintaining aquaria in good condition required a great deal of care and attention. The water had to be changed at least once a day if running water was not available, and altogether they were so much trouble that as a rule owners soon tired of them. Modern aquaria are totally different. By a proper combination of fish and growing plants we can almost duplicate the conditions of nature and strike a balance so that the water need never be changed except when it becomes foul or to clean the glass. - A Shadoof for drawing water from the Nile
The term sakkieh is applied to all the apparatus for raising water, but the proper name for the Egyptian pole and bucket is shadoof. The shadoof is very ancient, as it is represented on the walls of the tombs constructed three or four thousand years ago. - A type of camp fire that will burn all night
A type of camp fire that will burn all night To make a fire that will burn in front of the tent all night, first drive two green stakes into the ground at a slant and about five feet apart. Then lay two big logs one on each side of a stake to serve as andirons. Build a fire between these logs and pile up a row of logs above the fire and leaning against the stakes. You may have to brace the stakes with two others which should have a forked end. When the lower log burns out the next one will drop down in its place and unless you have soft, poor wood the fire should burn for ten hours. With this kind of a fire and with a leanto, it is possible to keep warm in the woods, on the coldest, night in winter. - A Woman's Head

An Arab school is a curiosity. The pupils study their lessons aloud, and make the place about as noisy as a political meeting, and how they can learn, any thing is a surprise to a person from the Occident, where silence is considered desirable in a school-room. - An excellent device for catching minnows
The simplest way to catch minnows is with a drop net. Take an iron ring or hoop such as children use and sew to it a bag of cotton mosquito netting, half as deep as the diameter of the ring. Sew a weight in the bottom of the net to make it sink readily and fasten it to a pole. When we reach the place which the minnows frequent, such as the cove of a lake, we must proceed very cautiously, lowering the net into the water and then baiting it with bits of bread or meat, a very little at a time, until we see a school of bait darting here and there over the net. We must then give a quick lift without any hesitation and try to catch as many as possible from escaping over the sides. The minnow bucket should be close at hand to transfer them to and care must be used not to injure them or allow them to scale themselves in their efforts to escape. - An Indian tepee

Left to right - The In-Curve, the out-curve, the drop and the out-drop The pitcher is the most important member of a ball team. Most of the work falls to him, and a good pitcher, even with a comparatively weak team behind him, can sometimes win games where a good team with a weak pitcher would lose. A good pitcher must first of all have a cool head and keep his nerve even under the most trying circumstances. He must also have good control of the ball and be able to pitch it where he wants it to go. After that he must have a knowledge of curves and know how by causing the ball to spin in a certain way to cause it to change its course and thus to deceive the batsman. The art of curving a ball was discovered in 1867. Before that time all that a pitcher needed was a straight, swift delivery. The three general classes of curved balls used to-day are the out-curve, the in-curve, and the drop. There are also other modifications called "the fade away," "the spitball," and others. Curve pitching will only come with the hardest kind of practice. - Beckoned silently to the rest to follow him
For some time this secret practising continued without arousing suspicion on the part of the other inmates of the house. One night, however, when the child had resorted to his favourite spot, he was suddenly missed by those below, and, as it was known that he had been sent to bed, some fears were felt as to what could have become of him. The servants were summoned, but could give no account of him; the father was fetched from his study, whither he had retired, and a search began. The alarm increased when it was ascertained that the child was in none of the living-rooms of the house, and it was decided that the garrets and lofts must be searched. Calling for a lantern, the surgeon ascended the stairs leading to the lumber-room; it was possible that the boy might have found his way thither on some childish expedition, and there fallen asleep. Great was the father's surprise, on reaching the top-most landing, to hear faint musical sounds proceeding from behind the closed door. Noiselessly retracing his steps, he summoned the rest of the household, and then, ascending the stairs in a body, they paused outside to listen. Sure enough the old garret was full of melodic sounds! Now near, now far off, they seemed to the listeners to be wafted from another world; there was something uncanny about it, and the maids gazed into each other's faces with a scared expression, as the master softly lifted the latch, and, having peeped [41]into the room, beckoned silently to the rest to follow him. - Beethoven
Ludwig van Beethoven - Biceps Muscle in Action
The power of muscle varies as its cross-section. For human muscles the maximum lift amounts to from 7 to 10 kilogrammes for each square centimetre. This is a large figure, but it must be remembered that, owing to the arrangement of the bones as levers, most muscles act at a great mechanical disadvantage. The greater the difference in distance from the fulcrum between the point of application of the force and the point of incidence of the weight, when the force acts nearer to the fulcrum than the weight, the greater is the mechanical disadvantage. The greater also is the rapidity with which the weight is lifted. What is lost in strength is gained in swiftness - Book Divider
Book Divider - By the light of the moon he began his task
Bach copying from his brothers book which he 'borrowed' Then, taking his pen and some manuscript music-paper with which he had provided himself, he began his task of copying out the pieces contained in the book. An hour or more slipped away in this absorbing occupation, and it was not until the moon had shifted her position, so that her rays no longer afforded the necessary light, that Sebastian ceased to ply his pen. Then, having hidden the book away and removed all traces of his work, the now wearied little musician sought his pillow and fell fast asleep. - Choice of fabric

Diagram of a Lobule of the Liver divided vertically through its Axis. In its centre is a space, the intralobular vein, through which the blood falls into a branch of the hepatic vein, on its way to the heart. An interlobular branch of the portal vein, which brings the blood from the digestive organs, pours it by many smaller vessels over the surface of the lobule. It filters into the lobule through innumerable pseudo-capillary vessels, or spaces, between the radiating columns of liver-cells. Arterial blood is brought to the lobule by a twig of the hepatic artery. Bile is drained away from it by an affluent of the hepatic duct. In the lower part of the diagram seven liver-cells are shown, forming a divided column, magnified about 300 diameters. The cells are loaded with glycogen, and contain minute globules of fat. Red blood-corpuscles and two leucocytes are seen between the columns of liver-cells. One of the leucocytes has ingested two blood-corpuscles. - Diagram showing the Relative Positions of the Organs of the Chest and Abdomen.
The ribs from the first to the tenth have been cut across in the lateral line. The eleventh and twelfth ribs do not reach sufficiently far forwards to be cut. With the exception of a short segment near its junction with the ascending colon, the small intestine has been removed. The trachea is seen to divide into bronchi beneath the arch of the aorta. The right lung has three, the left two lobes. The kidneys are situated behind all the other viscera. On their upper ends rest the two suprarenal capsules. The lower edge of the right lobe of the liver follows closely the line of the ribs and costal cartilages. Below the left lobe of the liver the stomach comes to the anterior abdominal wall. The transverse colon (large intestine) comes to the anterior wall below the stomach. Below the latter the wall is in contact chiefly with coils of small intestine. The vermiform appendix rests on the posterior wall. Spleen and pancreas are not shown in the diagram. - Digestive system in humans
The stomach has been cut across a short distance from the pyloric valve, and removed, to show the viscera which lie behind it. The descending aorta and the vena cava rest upon the vertebral column. They are crossed by the pancreas and the transverse portion of the duodenum. The head of the pancreas is enclosed by the curvatures of the duodenum. The ducts of the liver and pancreas are seen entering the descending duodenum side by side. - Divider

Divider - Donkey Drivers of Cairo
The beast par excellence of Egypt is the donkey; he ought to have a place on the national coat-of-arms, as much so as the llama has on that of Peru. The horses of Egypt are magnificent, some of pure Arabian, and some of a cross between English and Arabian stock, and are famous for their speed and beauty. But they are a luxury that not everybody can afford, as their support requires a constant outlay, not to speak of the first cost of the property. But the donkey is universal, and everybody can have one, unless he is the poorest of the poor. At every hotel door there are groups of them ready saddled at all hours of the day, and you can hire them cheaply. If you can make a bargain in advance you can hire a donkey at three or four francs a day, inclusive of the boy, to drive him, though the latter generally looks for backsheesh in addition to the price of the beast and saddle. I have hired donkeys frequently for half a franc an hour, though the hotel keepers tell you that a franc an hour is the proper fare. - Dredges at work in the Suez Canal

Description of first trip in the car When I got this car ready to run one night, I took it out and I had a young fellow with me; I thought I might need him to help push in case the car didn't work…. We ran from the area of the shop where it was built down on Taylor Street. We started out and ran up Worthington Street hill, on top of what you might call "the Bluff" in Springfield. Then we drove along over level roads from there to the home of Mr. Markham , and there we refilled this tank with water. [At this point he was asked if it was pretty well emptied by then.] Yes, I said in my account of it that when we got up there the water was boiling furiously. Well, no doubt it was. We refilled it and then we turned it back and drove down along the Central Street hill and along Maple, crossed into State Street, dropped down to Dwight, went west along Dwight to the vicinity where we had a shed that we could put the car in for the night. During that trip we had run, I think, just about six miles, maybe a little bit more. That was the first trip with this vehicle. It was the first trip of anything more than a few hundred yards that the car had ever made. - Egyptian Gamblers

'Christoph, I wish you would let me have that book of manuscript music which you have in your cupboard—the one which contains pieces by Pachelbel, and Frohberger, and Buxtehude, and ever so many others—you know which I mean. I will take such care of it if you will only lend it to me for a little while.' Christoph was about to leave the room, but he turned sharply to his little brother as the latter put his request. 'No, Sebastian, I will certainly not lend you the book, and I wonder that you have the impertinence to ask me such a thing! The idea of your thinking that you could study such masters as Buxtehude and Frohberger—a child like you! Get on with what I have set you to learn, and do not let me hear any more of such fancies!' With that Christoph shut the door behind him, and Sebastian was left to ponder sadly upon his elder brother's harshness in refusing to accede to his simple request. The disappointment was very keen, for little Sebastian had been longing to get possession of that precious volume. For several days past he had spent hours in his brother's absence gazing at its covers through the lattice doors of the cupboard, and feasting his eyes upon the names of the musicians which were written on the back in bold letters in Christoph's hand. - George Frederick Handel
George Frederick Handel - Greek Priest
Greek Priest - Handels Birthplace
Handel's birthplace, Halle, Saxony. George Frederick Handel, as the boy was named, was the son of a surgeon of Halle, Lower Saxony, in which town the child was born on February 23, 1685. Even before he could speak little George had shown a remarkable fondness for music, and the only toys he cared for were such as were capable of producing musical sounds. With this love for music, however, the father showed no sympathy whatever; he regarded the art with contempt, as something beneath the serious notice of one who aspired to be a gentleman, and that his child should have expressed an earnest desire to be taught to play only served to make him angry. - Hats 1
These two examples show how even a hat with drooping brim, if not too wide, can be worn by the stout person if trimming is adeptly used to direct the vision upward and lend an illusion of height. - Hats 2
Here trimming is used on two entirely different types of hats to give in each case added height to the figure and help in attaining a slenderizing appearance. Left—Hats with medium brims and high trimming are often becoming, especially if wide enough to avoid the pyramid effect. Right—High built trimming and delicate veils are advantageous where a double chin is the handicap. - He called to the coachman to stop
One day, when Handel was seven years old, his father announced his intention of paying a visit to the castle of the Duke of Saxe-Weissenfels. Handel was most anxious to be allowed to accompany his father, because he had heard that the Duke kept a great company of musicians to perform in his chapel. But the father refused his consent, and the boy turned away with a look of fixed determination in his eyes. 'I will go, even if I have to run every inch of the way!' Handel did not know then that forty miles lay between his home and the castle, but having formed his bold resolution he awaited the moment when his father set forth on his journey, and then, running behind the closed carriage, he did his best to keep pace with it. The roads were long and muddy, and although he panted on bravely for a long distance, the child's strength began at last to fail, and, fearing that he would be left behind, he called to the coachman to stop. At the sound of the boy's voice his father thrust his head out of the window, and was about to give vent to his anger at George's disobedience; but a glance at the poor little bedraggled figure in the road, with its pleading face, melted the surgeon's heart. They were at too great a distance from home to turn back, and so Handel was lifted into the carriage and carried to Weissenfels, where he arrived tired and footsore, but supremely happy at having won his point. - Highly Magnified Section through the Wall of a Circumvallate Papilla of the Tongue, showing Two Taste-Bulbs.
These sense-organs are groups of elongated epithelial cells, set vertically to the surface. Their cells are of two kinds—the one fusiform, slender, bearing each a bristle-like process which projects through a minute pore left between the superficial cells of the general epithelium; the other thicker and wedge-shaped. Nerve-fibres are connected with the fusiform cells. - Horizontal Section through the Right Eye
The slight depression in the retina in the axis of the globe is the fovea centralis, or yellow spot; the optic nerve pierces the ball to its inner or nasal side. The lens, with its suspensory ligament, separates the aqueous from the vitreous humour. On the front of the lens rests the iris, covered on its posterior surface with black pigment. On either side of the lens is seen a ciliary process, with the circular fibres of the ciliary muscle cut transversely, and its radiating fibres disposed as a fan. - Jean Cocteau

- Manometer for measuring Blood-Pressure
A U-tube contains mercury, on which floats a rod supporting a scratching point, which makes a “tracing” on blackened paper wrapped round a revolving drum. Between the manometer and the cannula which is introduced into the central end of a cut artery is a three-way cock, which leads to a pressure-bottle containing a half saturated solution of sodic sulphate. This solution prevents blood from clotting. Before it is connected with the artery the apparatus is filled from the pressure-bottle. The cock is then turned into the second position, and the bottle raised until the mercury in the manometer stands at a level somewhat higher than that which it may be expected to attain under the influence of blood-pressure. The cannula being then inserted into an artery, the cock is turned into the third position, which places the manometer in connection with the blood, and excludes the pressure-bottle. As the mercury is a little higher than blood-pressure, some of the sodic sulphate solution enters the artery, but no blood enters the cannula. The scratching point, rising and falling with every variation in blood-pressure, makes a record on the soot-blackened paper, which is subsequently removed from the drum, and varnished. - Only one Bach!
The King next requested him to play a six-part fugue, and Bach extemporised one on a theme selected by himself. The King, who stood behind the composer's chair, clapped his hands with delight, and exclaimed repeatedly, 'Only one Bach! Only one Bach!' It was a visit replete with honours for the old master, and when he returned home he expressed his gratitude by writing down and elaborating the piece which he had composed on the King's theme, dedicating it to His Majesty under the title of 'Musikalisches Opfer' (Musical Offering), and sending it to Potsdam with a letter begging its acceptance.
