Optical Illusion in dress
These unbroken parallel vertical lines give the definite impression of height. This principle, used in the design of the dress above, lends it a pleasing slender appearance because no other lines interfere with the straight line effect.

Optical Illusion in dress
Here, also, are two vertical parallel lines. They are straight—test them—but the other lines radiating from the center, make them appear “bowed.” In the dress above a similar design makes the wearer appear stouter and heavier than she really is.

Optical Illusion in dress
These two diamond-shaped figures are exactly the same size. The crosswise line makes one seem wider, the vertical line makes the other seem narrower.

Optical Illusion in dress
Now note how these same principles used in the dresses above effect the apparent size and weight of those wearing them, making one seem much stouter than the other.

Optical Illusion in dress
The middle lines in the two small diagrams are the same length. But on the left, shorter accompanying lines seem to shorten the one between. On the right longer accompanying lines seem to lengthen the one between.

Optical Illusion in dress
Now see how the woman in the other picture has unknowingly emphasized her stoutness while the one in this picure has properly gained a slender effect by using trimming in accordance with the principles of these optical illusions.

Optical Illusion in dress
The oblique line in the figure is made to seem longer and more graceful than the dress below by the parallel vertical lines of embroidery which intersect it and so emphasize its appearance of length and grace.

Optical Illusion in dress
Note the diagonal line in the small diagram of the figure below. It is actually straight, but the vertical lines which break it give it a “going-down-steps” appearance. This principle is used in the dress below—the two vertical panels of trimming break the line of the tunic and give the whole figure a more slender appearance than in the figure above.

Organ of Corti
The spiral lamina, on the left of the drawing, gives attachment to the membrane of Corti, which stretches to the opposite wall. Below the membrane is a bloodvessel which runs its whole length beneath the tunnel of Corti. The tunnel is formed by pillars—the inner on the left, the outer on the right—which meet above it. On the left of the inner pillar is a hair-cell; to the left of this a nerve-cell with two nuclei. To the right of the outer pillar is a space; to the right of this four hair-cells alternating with four supporting cells, which hold up the reticulated membrane through apertures in which the tufts of hairs project. Three nerve-fibres are seen in the spiral lamina; they cross the tunnel to ramify between the rows of outer hair-cells. The lamina tectoria rests upon the tufts of hairs.

Plaits 1
When styles call for plaits, plaits may be used, but not in widening flares as shown here, rather in slenderizing length lines as shown below

Plaits 2
Hats and shoes in these two pictures also illustrate incorrect and correct choice. The wide hat and prominent straps below emphasize width and weight; the neat hat and cross-strap slippers here help to slenderize

Plan of Harpers Ferry Bridge
Shortly after the Harpers Ferry bridge reconstruction, Bollman was made foreman of bridges. It is apparent that, on the basis of his practical ability, enhanced by the theoretical knowledge gained by intense self-study, he eventually came to assist Chief Engineer Benjamin H. Latrobe in bridge design. He later took this work over entirely as Latrobe’s attentions and talents were demanded in the location and extension of the line between Cumberland and Wheeling.

Red Blood-Corpuscles presenting, some the Surfaces, others the Edges, of their Discs, together with Single Representatives of Four Types of Leucocyte.
A, the most common type, highly amœboid and phagocytic. Its protoplasm is finely granular, its nucleus multipartite. B, a leucocyte closely similar to the last, but larger, and containing an undivided nucleus. It is shown with a cluster of particles of soot in its body-substance. C, a young leucocyte, or “lymphocyte.” D, a coarsely granular leucocyte. Its granules stain brightly with acid dyes—e.g., eosin or acid fuchsin.

Scholars went out to sing
Lüneburg possessed two schools, attached respectively to the Churches of St. Michael and St. John, and the rivalry between the two was so keen that when, as was the custom during the winter months, the scholars were sent out to sing in the streets in order to collect money for their support, the respective routes to be traversed had to be carefully marked out so as to prevent a collision.

Section of First-rate Man-of-War
I will now give you a sectional division of a first-rate line-of-battle ship. Such a ship, carrying 120 or more guns, has four decks on which her guns are placed. The highest is open to the air, and is called the UPPER DECK At the after part, extending a little way beyond the mizen-mast, there is a raised platform, called the POOP. It has no guns on it. On the main deck is the steering-wheel, with the binnacle in front of it. The after part of this deck between the poop and the main-mast is called the quarter-deck, and is the place where the officers especially walk. The part under the poop is divided into cabins, appropriated to the use of the captain. Here, also, is a clerk's office and a pantry. Between the main and fore-mast the large boats are stowed, and on either side are the gangways at which sentries are stationed. The next deck under this is called the MAIN DECK. In the after part is the admiral's cabin. Immediately under the boats is a pen for the officers' live-stock ; and just abaft the fore-mast is the galley, or kitchen. The third deck from the upper is called the MIDDLE DECK. The after part is fitted up for the lieutenants, chaplain, surgeon, paymaster, marine officers, &c., and called the WARD-ROOM. In the fore part of the deck is placed the sick-bay, a compartment fitted up as a hospital ; about the centre of this deck is one of the capstans. The fourth from the upper is called the LOWER or GUN DECK. In the after part is the GUN-ROOM, where the midshipmen, and other junior officers, mess. The tiller of the rudder works through the gun-room just above their heads. A second capstan is placed on this deck ; and forward are the riding-bitts for securing the cables. It is the lowest deck on which guns are carried. The ORLOP DECK is the fifth deck from the upper. It has no guns or ports, though lighted up by bull's eyes or scuttles. In the after part is the purser's issue-room ; next to it is the after cockpit, where the midshipmen and other junior officers sleep in hammocks. Before it again will be found the sail-room, where the sails are kept, and the cable-tiers, where the cables are stowed. Before it again, just abaft the fore-mast, is the fore cockpit, and the warrant officers' cabins, while right in the head of the ship are the carpenter's and boatswain's stores. Low as we have got, we have still further to go down to the HOLD, which, if it may be so called, is the sixth deck from the highest. It is often divided into two decks for the greater convenience of stowage. Here are the FORE AND AFTER MAGAZINES, WATER TANKS, WINE AND SPIRIT ROOM, CHAIN CABLE LOCKERS, SHOT LOCKERS, BREAD ROOM, SHELL ROOM, GUNNER'S STORE ROOM, DRY PROVISION, and BEEF AND PORK IN CASKS. Since the introduction of auxiliary steam-power into ships of war, a large portion of the hold is devoted to the steam-engine and boilers, coal bunkers, and the shaft of the screw, while the funnel runs up through all the decks ; but it is wonderful, comparatively, how little space these are allowed to occupy, considering the great aid the steam-engine affords to the movements of the ship.

Sense-Organs susceptible to Pressure
All are formed on essentially the same plan; a fibrous capsule invests a group of epithelial cells amongst which a nerve ramifies. The simplest form is known as a Grandry’s corpuscle-a nerve ending in one or two plates between two or three epithelial cells. These organs are found in great numbers in the bills of aquatic birds. If a duck is watched whilst it is gobbling mud at the margin of a pond, it will be seen to have a remarkable capacity for discriminating between the shells of small snails, which it can crush, and stones, which it needs to drop from its bill. Its bill is also provided with small Pacinian corpuscles.

The 'Minotaur'
Launched in 1863 Among the numerous huge monsters constituting the iron-clad fleet of England, the Minotaur, is one of the most gigantic and formidable; and the sister ships, the Agincourt and Northumberland, all of precisely the same tonnage, power, rig, and equipment, are the largest and most powerful ships in the navy. The Minotaur was built at Blackwall, by the Thames Ship Building company and the engines were constructed by Messrs. Penn, of Deptford. She is 6,621 ton's measurement, and propelled by screw engins of 1,350 horsepower, with a speed of 15 knots an hour. She is 400 feet in length by 59 in width, and carries in all thirty-four of the heaviest guns used afloat. Among these which form her chief batter on the main deck are four 300-pounder Armstrongs.

The Anterior Half of the Larynx seen from Behind
The drawing shows the folds of mucous membrane, the vocal cords, which stretch from the tips of the arytenoid cartilages to the recess behind the median portion of the thyroid cartilage. To the outer side of each vocal cord is seen the thyro-arytenoid muscle (cut across), consisting of a broad outer portion, chiefly concerned in closing the glottis during the act of swallowing, and a smaller internal portion, which regulates the length and the thickness of the segment of the cord allowed to vibrate.

The Body of a Motor Neurone
In its centre is a large clear spherical nucleus, with a nucleolus. The body-substance is prolonged into five dendrites and an axon. Neuro-fibrillæ are seen in dendrites and axon. They traverse the body of the cell in all directions, in little bundles which are separated by angular granules of stainable substance (tigroids).

The Bull of Japan attacking the Mundane Egg
Sculptures and medals abound in the East, containing hieroglyphic symbols of the creation. The most remarkable, however, of these symbolic devices is that erected, and at this day to be seen, in one of the temples of Japan. The temple itself, in which this fine monument of Oriental genius is elevated, is called Daibod, and stands in Meaco, a great and flourishing city of Japan. The principal image in this design displays itself in the form of a vast bull, the emblem of prolific heat and the generative energy by which creation was formed, butting with its horns against the egg, which floated on the waters of the abyss. The status of the bull itself is formed of massy gold, with a great knob on its back, and a golden collar about its neck, embossed with precious stones.

The Diaphragm and Organs in Contact with it
The Diaphragm and Organs in Contact with it—A, in Expiration; B, at the End of a Deep Inspiration. Transverse Vertical Sections in the Line of the Armpit. A, At the end of an ordinary expiration the lung does not extend below the upper border of the eighth rib. From this level to the middle or lower border of the tenth rib the two layers of the pleura covering respectively the inner wall of the chest and the upper surface of the diaphragm are in contact. B, When the lung is distended with air it occupies the whole of the pleural cavity.

The Duke praised his performance
On several occasions after this the organist came to the chapel on purpose to listen to Handel as the latter played, and he was so struck by the boy's genius that he determined to surprise the Duke by letting Handel play His Highness out of chapel. Accordingly, on the following Sunday, when the service was concluded, the organist lifted Handel on to the organ-stool, and desired him to play. The Duke and his friends had risen to their feet as Handel began to play, but the Duke instantly detected a difference in the playing, and, glancing towards the organ-loft, he was astonished to behold the figure of a child bending over the keys. But as he listened his astonishment became greater, for it was no longer the child's figure that arrested his attention, but the melody which was pouring forth from the instrument. Instead of walking out of the chapel, the Duke remained standing where he had risen, with his gaze riveted upon the child player, and of course the members of the household likewise kept their places. At length, when Handel ceased to play, the Duke turned to those about him with the inquiry: 'Who is that child? Does anybody know his name?' As no one present seemed to know, the organist was sent for to explain matters. After a few words from this official the Duke commanded that Handel should be brought before him. When the boy appeared he patted him on the head, and praised his performance, telling him that he was sure that he would make a good musician.

The External, Middle, and Internal Ear of the Left Side
From right to left, the figure shows the concha and lobule of the ear in profile; the external meatus (abbreviated); the drum, divided vertically, its posterior half visible; the hammer-bone, with the tip of its long arm attached to the drum, an arrow indicating the point of attachment and line of action of the tensor tympani muscle; the anvil attached by a ligament to the bony wall of the middle ear; the stirrup, with its foot-plate almost filling the oval window; the labyrinth, with the three semicircular canals above, and the scala vestibuli below. The curled black line shows the situation of the scala media, or ductus cochleæ (which contains the organ of Corti). Pulsations of sound which move the membrana tympani are transmitted by the three bones to the oval window. They shake the perilymph, producing waves which travel along the scala vestibuli to the apex of the cochlea, whence they return by the scala tympani to the round window (if they do not take a shorter course through the ductus cochleæ). The Eustachian tube opens out of the lower part of the middle ear.

The Growth and Migration of Granules of the Cerebellum
Half a dozen nuclei of as yet undeveloped granules are seen lying beneath the pia mater. From this level to the bottom of the drawing granules are shown in successive stages of growth. These developing granules, selected from various preparations of the cortex of the cerebellum, were drawn from nature.

The Surface of the Left Cerebral Hemisphere, Cerebellum,and Medulla Oblongata.
Sensory areas are enclosed by broken lines; certain centres in the association-zones are marked by dots. The sensory area of smell is on the inner aspect of the brain; so also is the area of vision which borders the calcarine and retrocalcarine fissures, and only rarely extends on to the external surface, as shown in the diagram. The sensory area of hearing is largely hidden within the fossa of Sylvius, the opening into which is indicated by the dark line above it. The kinæsthetic-sensory areas for the various muscles of the body occupy the territory between the dotted line in front and the bottom of the fissure of Rolando behind. They do not extend on to the posterior wall of this fissure. It is impossible at present to define the boundaries of any of the centres in the association-zones.

The Wilderness Traveller
Forest travellers are always on the lookout for peculiar landmarks that they will recognize if they see them again. Oddly shaped trees, rocks, or stumps, the direction of watercourses and trails, the position of the sun, all these things will help us to find our way out of the woods when a less observing traveller who simply tries to remember the direction he has travelled may become terrified.

Truth
The four figures in the Vignette are intended to represent the chief protestant reformers; Luther in the centre, Cranmer on his right hand, Knox on his left, and Calvin on his extreme right; each holding in his hand a manuscript or printed copy of the Word of God. the Rock on which they are standing, is intended to denote the Truth of the doctrine of the Divine Oracle, on which, as on an immutable Rock, the Reformers rested all their claims, in labouring to restore pure Christianity. Around the Rock of Truth, the waves of Error and Superstition are seen dashing.

Two looks - same pattern
Would you believe that the pattern of these two dresses is exactly the same? This illustrates how you can vary a dress once you find the foundation lines that are becoming to you. One pattern can suffice for both a tailored and an afternoon dress, as you see both effects are pleasing in their slenderness.

Wendell Bollmans Patent Bridge
Patent Iron Suspension Railroad Bridge. The undersigned would inform the officers of Railroads and others, that he is prepared to furnish Drawings and Estimates for Bridges, Roofs, etc., on the plan of Bollman’s Patent. The performance of these bridges, some of which have been in use for six years, has given entire satisfaction. Their simplicity of construction renders repairs easy and cheap, and by a peculiar connection of the Main and Panel Rods at the bottom of the Posts, all danger from the effects of expansion, which has heretofore been the chief objection to Iron Bridges, is entirely removed.
