Evacuation of Corinth, Mississippi- Confederate fortifications, from the northern angle, looking south- pursuit of the retreating Confederates by the Federal Cavalry under General Smith. The details of the evacuation of Corinth, by Beauregard, beyond those contained in the official reports of General Halleck, were that Beauregard's force did not exceed 60,000 men. Nobody was left in town except women and children and old men; everything was taken away except a few provisions, which were burned. They did not leave a single gun, and had been moving their stores for two weeks, and their troops for six days. Their fortifications were five miles long, extending from the Memphis and Charleston to the Mobile and Ohio Roads. But they were much weaker than supposed. They could have been carried by storm at any time.

"The investment of Fort Hindman, Arkansas Post, Ark., by the Federal troops under General McClernand, and its bombardment by the Federal gunboats commanded by Rear Admiral D. D. Porter, January 11th, 1863. Fort Hindman was what is known in military parlance as a star fort, with four angles- two on the river and two extending nearly to the morass in the rear. In front of the southwestern angle was a cluster of small houses, into which the enemy had thrown their sharpshooters, and from which a most galling fire was poured upon Burbridge's brigade, which stormed them and carried them by assault. At the given signal, on went the splendid brigade with a shout and a yell, now floundering like bemired horses in the morass, then pausing to dress their lines as if on parade, and anon charging again, regardless of the storm of grape and shell, shot and canister that pelted pitilessly around them. For three long hours they fought ere the houses were carried and made to screen the Federal troops. All that while sharpshooters were picking off, from their secure hiding places, officers and men; 10-pound Parrotts were sending their hissing messengers of death through the lines of the devoted brigade, crushing its bones, spattering its brains, and strewing its path with mangeled corpses and dying men. At last the houses were gained and occupied by the Eighty-third Ohio, which, with the Ninety-sixth Ohio, the Sixteenth, the Sixtieth and Sixty-seventh Indiana and the Twenty-third Wisconsin, had fought for them so gallantly."— Frank Leslie, 1896

Beloeil Mountain, this sketch is taken from the southeast angle of old Fort chambly, showing the rapids in the forground. The mountain is twenty miles distant, near the Sorel. On the highest point of the range the Bishop of Nancy, a French prelate, erected a huge cross in 1843, the pedestal of which was sufficiently large to form a chapel capable of containing fifty persons. In November, 1847, during a severe thundergust, the lightning and wind completely emolished the cross, but spared the pedestal, and that, being white, may be seen at a great distance.

"The Gorilla is a celebrated anthropoid ape, generally belived to come nearer than any known one to man. The height is about 5 feet, almost the same as man. On the other hand, the greatest capacity of the gorilla's brain is only 34 and one half cubic inches, the least 23 against 62 in the least capacious human skull, and 114 in the greatest. The low facial angle also, and the abundant hair, with the extraordinary breadth of the chest, diminish the resemblance. The last mentioned characteristic imparts to the animal a colossal strength. It is a native of Lower Guinea and the interior of equinoctial Africa."—(Charles Leonard-Stuart, 1911)

"Hedgehog is a quadruped distinguished by having the body covered with spines instead of hair. The skin of the back is provided with a great orbicular muscle which enables the animal to roll itself up in the form of a ball. The tail is very short. There are several species—some authorities enumerate 14. The best known is the common hedgehog. This species has a long nose, the nostrils bordered on each side by a loose flap; the hind feet have five toes; the ears are short, rounded, naked and dusky; the upper part of the face, sides, and rump covered with strong, coarse hair, of a yellowish ash color, the back with sharp strong spines of a whitish tint with a bar of black through their middle. They are usually abot 10 inches long, the tail about one. Their usual residence is in small thickets, and they feed on fallen fruits, roots, and insects; they are also fond of flesh, either raw or roasted. The hedgehog defends himself from the attacks of other animals by rolling himself up, and thus exposing no part of his body that is not furnished with a defense of spines. It may be rendered domestic to a certain degree, and has been employed to destroy cockroaches which it pursues with avidity. In the winter the hedgehog wraps itself in a warm nest, composed of moss, dried hay and leaves, and remains torpid till spring."—(Charles Leonard-Stuart, 1911)

"The Metacenter is the point of intersection of the vertical line passing through the center of gravity of a floating body in equilibrio, and a vertical line through the center of gravity of the fluid displaced, if the body be turned through a small angle, so that the axis takes a position inclined to the vertical. If the metacenter is above the center of gravity, the position of the body is stable; if below it, it is unstable."—(Charles Leonard-Stuart, 1911)

"Ancilia carried by Salii. The sacred shield carried by the Salii, and made of bronze. The original ancile was found, according to tradition, in the palace of Numa; and, as no numan hand has brought it there, it was concluded that it had been sent from heaven. At the same time, the haruspices declared that the Roman state would endure so long as this shield remained in Rome. To secure its preservation in the city, Numa ordered eleven other shields, exactly like it, to be made by the armourer, Mamurius Veturius, and twelve ancilia. They were kept in the temple of that divinity, on the Palatine mount, and were taken from it only once a year, on the calends of March. The feast of the god was then observed during several daysl when the Salaii carried their shields about the city, singing songs in praise of Mars, Numa, and Mamurius Veturius, and at the same time performing a dance, which probably in some degree resembled our morris with rods, so as to keep time with their voices, and with the movements of their dance. The preceding cut shows one of these rods, as represented on the tomb of pontifex salius, or chief of the Salii" — Smith, 1873

"Athens is said to have derrived its name from the prominence given to its worship of Athena by its king erechtheus. The inhabitants were previously called Crannai and Cecropidae, from Cecrops, who, according to tradition, was the original founder of the city. This at first occupied the hill or rock which afterwards became the <em>Acropolis</em>, but gradually the buildings began to spread over the ground at the southern foot of this hill. It was not till the time of Pisitratus and his sons (B.C. 560-514) that the city began to assume any degree of splendour. The most remarkable of these building deposits was the gigantic temple of the Olympian Zeus, which, however, was not finished till many centuries later."— Smith, 1882

"An athletic game, in which all the powers of the fighter were called into action. The pancratium was one of the games or gymnastic contests which were exhibited at all the great festivals of Greece; it consisted of boxing and wrestling, and was reckoned to be one of the heavy or hard exercises, on account of the violent exertions it required, and for this reason it was not much practised in the gymnasia. In Homer we find neither the game nor the name of the pancratium mentioned, and as it was not introduced at the Olympic games until Ol. 33, we may presume that the game, though it may have existed long before in a rude state, was not brought to any degree of perfection until a short time before that event. The name of the combatants was Pancratiastae, or Pammachi. They fought naked, and had their bodies anointed and covered with sand, by which they were enabled to take hold of one another. When the contest began, each of the fighters might commence by boxing or by wrestling, accordingly as he thought he should be more successful in the one than in the other. The victory was not decided until one of the parties was killed, or lifted up a finger, thereby declaring that he was unable to continue the contest either from pain or fatigue." — Smith, 1873

Interior of the ear. There is external to the head a wide-mouthed tube, or ear-trumpet (a), for catching and concentrating the waves of sound. It is movable in many beings, so that they can direct it to the place from which the sound comes. The sound concentrated at the bottom of the ear-tube falls upon a membrane stretched across the channel, like the parchment of an ordinary drum, over the space called the <em>tympanum</em>, or <em>drum of the ear</em> (b), and causes the membrane to vibrate. That its motion may be free, the air contained within the drum has free communication with the external air by the open passage (f), called the <em>eustachian tube</em>, leading to the back of the mouth. A degree of deafness ensues when this tube is obstructed, as in a cold; and a crack, or sudden noise, with immediate return of natural hearing, is, generally experienced when, in the effort of sneezing or otherwise, the obstruction is removed. The vibrations of the membrane of the drum are conveyed further inwards, through the cavity of the drum, by a chain of four bones (not here represented on account of their minuteness), reaching from the centre of the membrane to the <em>oval door</em> or <em>window</em>, leading into the labyrinth (e). The labyrinth, or complex inner compartment of the ear, over which the nerve of hearing is spread as a lining, is full of watery fluid; and, therefore, by the law of fluid pressure, when the force of the moving membrane of the drum, acting through the chain of bones, is made to compress the water, the pressure is felt instantly over the whole cavity. The labyrinth consists of the <em>vestibule</em> (e), the three <em>semicircular canals</em> (c), imbedded in the hard bone, and a winding cavity, called the <em>cochlea</em> (d), like that of a snail-shell, in which fibres, stretched across like harp-strings, constitute the <em>lyra</em>.

"E represents the scape-wheel turning in a minute, and e its pinion, which is driven by the wheel D having a pinion d driven by the wheel C, which we may suppose to turn in an hour. The arbors of the scape-wheel and hour-wheel are distinct, their pivots-meeting in a bush fixed somewhere between the wheels. The pivots of the wheel, D are set in the frame AP, which rides on the arbors of the hour-wheel and scape-wheel, or on another short arbor between them. The hour-wheel also drives another wheel G, which again drives the pinion f on the arbor which carries the two arms f A, f B; and on the same arbor is set a fly with a ratchet, like a common striking fly, and the numbers of the teeth are so arranged that the fly will turn once for each turn of the scapewheel. The ends of the remontoire arms f A, f B are capable of alternately passing the notches cut half through the arbor of the scape-wheel, as those notches successively come into the proper position at the end of every half minute; as soon as that happens the-hour-wheel raises the movable wheel D and its frame through a small angle; but nevertheless, that wheel keeps pressing on the scape-wheel as if it were not moving, the point of contact of the wheel C and the pinion d being the fulcrum or center of motion of the level A d P." — Encyclopedia Britanica, 1893
