The cycle of the heart in its diastole (relaxation) state and its systole (contraction) state. The ventricles can be in a diastolic state, while the atria can be in a systolic state. An auricle is a small conical projection coming out of the atrium, but in some texts it represents the actual atrium. As the heart relaxes, blood enters from the other side and into the atria, then leaves and enters the ventricles. When the heart contracts, blood leaves the ventricles and goes back into the body.

A complex anatomical view of the heart. RA is the right atrium, or auricle, which receives the deoxygenated blood by way of two superior vena cava (SVC) and one inferior vena cava (IVC). The blood passes through the right ventricle (RV) and is pumped up to the lungs via the pulmonary arteries (PA). At the lungs, the blood is reoxygenated and returns via the pulmonary vein (PV) and left atrium/auricle (LA). From there, the blood is passed to the left ventricle (LV) where the blood is pumped up through the systematic arch (SA) to the body. The systematic arch gives off a right innominate artery (INN), where the blood is then passed to the right and left carotid (C) and subclavian (SCL), where the blood goes to the head and arms respectively. It continues dorsally to the dorsal aorta (DA), which is the main artery that distributes blood to the whole body. TR is the windpipe, or trachea, BR is the bronchial tube that carries air to the lungs, and BV is a blood vessel on the wall of the heart.

Nerve Ganglia, or Knots (sing. Ganglion; Knot) occur as collections of nerve cells on the course of a nerve, forming and obvious swelling. In surgery, it is the swelling caused by the collection of fluid in the fibrous sheath which surrounds a tendon. It arises from inflammation of the tendon-sheath, and occurs most often at the back of the wrist. Sometimes the cyst may be broken by firm pressure or by a smart blow, and the fluid be thus dispersed; or a puncture may be made, with proper antiseptic precautions, and the fluid be pressed out. Sometimes counter-irritation with iodine causes absorption. In any case, firm pressure with pad and bandage must be used afterwards, to prevent refilling until the cyst walls have united. This illustration shows a cross-section of a spinal cord and spinal nerve cells (g being ganglia).

Also known as a Solan Goose (Sula bassana), the Gannet is a large marine bird which nests in scattered localities in most parts of the world. Its specific name refers to the fact that it has long been a denizen of Bass Rock -- a famous craggy islet on the coast of England. This bird also nests on Bird Rock in the gulf of St. Lawrence, and other species exist in the tropics. It belongs to the same sub-order as the cormorant, and may be recognized by the fact that, as in the latter, all four toes are united by a web. Its bill is long, strong, and compressed to a point. In adult life, the plumage is white, save for the black primaries and a buff patch on the head or neck; the young are dusky, and do not acquire the white plumage until their sixth year. Their nests contain only one egg.

The Gauntlet is a piece of protective armor for the hand, dating back to the 12th century. The first gauntlets were leather covered gloves with an unarticulated metal back. They evolved from the chain mail bag, which , in the 12th century, terminated at the sleeves of the hauberk. The gauntlet of the 14th century had separate, but unjointed fingers. This gauntlet was superseded by the 'mitten'.

A gecko is a small, four-footed member of the lizard family Geckonidae. Geckos are widely distributed throughout the world, inhabiting primarily warm countries. They are usually dull in color; the eyes are without movable lids; the tail is brittle; while the feet of most species are remarkable for their adhesive digits, which enable the animal to not only climb on smooth surfaces, but even to run along ceilings and back downward. The geckos are insect-eaters and are harmless to man.

This illustration shows various types of gladiators, each type with with his specific weapons attributed to him. Gladiators were swordsmen whose profession was to fight for the public amusement. Gladiators are said to have been borrowed by Rome from the Etruscans. They were first exhibited in Rome in 246 BC, primarily at funerals, but afterwards at festivals, particularly those celebrated by the aediles and other magistrates. More than ten thousand were shown at Trajan's triumph over the Dacians. They were either free-born citizens, usually of a low class, who fought for hire, or captives, slaves, or malefactors, and were kept in schools, where they were carefully trained. Chief varieties were Andabatae, who wore helmets with no openings for the eyes, so that their blindfold movements provoked the spectators' mirth; Mirmillones, who used Gallic weapons, sword and shield; Retiarii, who carried a net and a three-pronged lance -- the net to entangle their opponents; and Thraces, who, like the Thracians, used a short sword and a round buckler. When a gladiator was severely wounded and defeated, the people cried out 'Habet' (He has it), and he lowered his arms; then, if the spectators wished his life to be spared, they turned their thumbs down; but it they desired his death, they turned them up. These combats were often attended by great cruelty and callousness on the part of the spectators; sometimes they were fights à outrance, none being spared alive. Discharged gladiators were presented with a rudis, or wooden sword, and hence were called rudiarii. Gladiatorial combats were disliked by the Greeks, and practically never took place in Greek cities.

In heraldry, the griffin is a fabulous animal, with the head and forefeet of an eagle, and the body, hind legs, and tail of a lion. The head is represented with pricked ears, symbolical of its vigilance. In mythology, the griffin was a creature similar in form to the griffin of heraldry, which was supposed to find its especial function in watching over hidden treasure, especially in Scythia. It was dedicated to the sun-god Apollo, whose chariot appears in early art as drawn by griffins. It was a favorite ornamental 'theme' in ancient Babylonian and Persian art, and is also found in a similar way on art objects of the Phoenicians, the Mycenæan civilization, and the ancient Greeks. The Romans and art-workers of the renaissance used it as a purely decorative device.

Jute, also known as Calcutta Hemp, is a fiber obtained from several species of the genus Corchorus of the order Tiliaceæ, and employed in the manufacture of the coarser textiles. The great bulk of the world's supply is derived from two species, C. capsularis and C. olitorius (Jew's Mallow), both of which are indigenous to Bengal, India, where from remote times they have been cultivate for economic purposes. The two species are similar in appearance, but may be distinguished by the form of the seed pods, which are nearly spherical in C. capsularis, and long and narrow in C. olitorius. Both plants are herbaceous annuals with straight, slender stalks from 5 to 15 feet in height, branched at the top, and bearing small yellow flowers. The fiber, which is derived from the inner bark, is of a creamy yellow or light buff color and of a silky luster. It spins well, but is not as strong as flax or hemp, and deteriorates rapidly. The young shoots are used as pot herbs. Jute is grown chiefly in Bengal, though it is raised to a limited extent in China, Formosa, and Southern Japan. It can be grown successfully in the South Atlantic and Gulf States of the United States, but lack of mechanical methods for preparing the fiber has prevented its cultivation on an industrial scale. Attempts to naturalize it elsewhere have generally failed. For its most successful cultivation, jute requires a soft, deep soil and a hot, moist atmosphere, alluvial lands being especially adapted to its production. This illustration shows Corchorus capsularis.
