Ichabod Crane

a Yankee schoolmaster in The Legend of Sleepy Hollow in Irving's Sketch Book. Ichabod is a suitor for the hand and inheritance of Miss Katrina Van Tassel. He has a startling adventure with the Headless Horseman and disappears forever from the neighborhood of Sleepy Hollow. See Irving The cognomen of Crane was not inapplicable to his person. He was tall, but exceedingly lank, with narrow shoulders, long arms and legs, hands that dangled a mile out of his sleeves, feet that might have served for shovels, and his whole frame most loosely hung together. His head was small, and flat at top, with huge ears, large green glassy eyes, and a long snipe nose, so that it looked like a weathercock, perched upon his spindle neck, to tell which way the wind blew. To see him striding along the profile of a hill on a windy day, with his clothes bagging and fluttering about him, one might have mistaken him for the genius of famine descending upon the earth, or some scarecrow eloped from a corn-field.--Washington Irving, The Sketch-Book.

Ichang

a walled town in the Chinese province of Hu-pei; on the Yang-tsze-Kiang, where it escapes from the limestone gorges and ravines of its middle course; 1,000 miles from Shanghai. In 1877 it was declared open to foreign trade, but in consequence of the difficulties connected with the navigation of the river, the competition of the Chinese, and official jealousy it advanced but slowly.

Ichneumon Fly

a family of two-winged insects. There are over 1,000 species of ichneumon flies, differing very considerably, but having in common a family characteristic of depositing their eggs in or on the larvae of other insects. Some species deposit their eggs on the bodies of caterpillars. The body of the female usually terminates in an awl-shaped egg depositor, which, in some species, is much longer than the body of the fly itself. Many species use the ovi-depositor as a drill. One in particular is able to locate larvae in a dead tree or twig accurately. It throws its drill up over its body in a long curve and hammers away on the wood until it has reached the larva within. It then deposits an egg in the body of the unfortunate grub, and leaves it to hatch out and feed on its host. In this way ichneumon flies destroy countless millions of insect pests. They are as useful in their way as are the ichneumons of Egypt from which they are named.

Ichthyornis

a fossil genus of carnivorous and probably aquatic birds, one of the earliest known American forms. It is so named from the character of the vertebræ, which, even in the cervical region, have their articular faces biconcave as in fishes. It is also characterized by having teeth set in distinct sockets.

Ichthyosaurus

an extinct fish-lizard; the typical genus of the order Ichthyosauria. It consists of gigantic fossil marine reptiles, with jaws which show them to have been carnivorous. Their vertebræ were fishlike, their paddles like those of a porpoise or a whale, and their long powerful tail a propeller which enable them to dart with great rapidity through the water. The genus extended from the Trias of Germany to the White Chalk of England.

Iconium

an ancient town of Asia Minor, on the W. edge of the plateau that skirts the N. slopes of the Taurus Mountains. The capital under the Romans of Lycaonia, it was three times visited by St. Paul, who founded there a Christian Church. In 708 it fell into the hands of the Arab conquerors. Its prosperity culminated in the end of the 11th century, when it was made the capital of the Seljuk empire. In 1190 Frederick Barbarossa defeated the Turks in the neighborhood, and captured Iconium. In 1832 Ibrahim Pasha defeated the Turks there. The modern town, called KONIA, the capital of the Turkish vilayet of the same name, is a place of some 30,000 inhabitants, who live by commerce, by making stockings and gloves, and on the contributions of the numerous pilgrims who visit the holy places of the town. Here is the principal monastery of the Mevlevi or "dancing" dervishes in the Ottoman empire.
