Tick

Tick, the common name of several families of small arachnids infesting the skin of man and the lower animals. In addition to what has been given under Epizoa and Mite, it may be stated that, from the young tick having only three pairs of legs instead of the four pairs of the adult spider and mites, some have maintained that the arachnids form an order of the class of insects, and not an independent class. The legs also in the young are very long and the head separate from the thorax, as in the insect. (See "American Naturalist," vol. iii., 1869, pp. 364-373).

Tigre

Tigre, a state of Abyssinia, between lat. 12° and 16° N, and Ion. 37° 25' and 40° E. It is an elevated plain, which forms the basis of several mountain ranges and lofty groups, and is drained in the north by the Mareb and in the south by the Tacazze. The plateau itself varies from 3,500 to 9,000 ft. in elevation, and is deeply indented by the ravines which form the beds of the principal rivers. The Tacazze is second only to the Bahr el-Azrek in size among the rivers of Abyssinia. Tigre is divided into many petty chieftaincies or districts; the principal towns are Antalo, formerly the capital, Axum, and Adowa, the present capital. Adowa, the largest town, is the entrepot of trade on the great caravan route between Massowah and Gondar, and has considerable manufactures. - Tigre was for many years an independent kingdom, but in 1855 was conquered by Theodore, king of Abyssinia, who made it a province of his empire. (See Abyssinia).
