INTESTINE (Lat. intestinus, internal, usually in neuter plural intestina, from intus, within), in anatomy, the lower part of the alimentary canal; in man and mammals divided into the smaller intestine, from the pylorus to the iliocaecal valve, and the larger, reaching from the caecum and colon to the end of the rectum. The word is frequently applied to the whole of the alimentary canal in invertebrates. (See [Alimentary Canal].)
INTOXICATION (Lat. toxicare, intoxicare, to smear with poison, toxicum, an adaptation of Gr. τοξικόν, sc. φάρμακον, a poison smeared on arrows; τόξον, bow), poisoning, or the action of poisons, whether of drugs, bacterial products, or other toxic substances, and hence the condition resulting from such poisoning, particularly the disorder of the nervous system produced by excessive drinking of alcohol (see [Inebriety] and [Drunkenness]).
INTRA, a town of Piedmont, Italy, in the province of Novara, on the W. shore of Lake Maggiore, 685 ft. above sea-level, 12 m. N. of Arona by steamer. Pop. (1901) 6924. It is situated between two torrents, which afford water-power for cotton and silk mills, hat factories, foundries, &c.; these chiefly belong to Swiss proprietors, who have fine villas with beautiful gardens. The church is a large edifice of 1708-1751.
INTRADOS (a French term, Lat. intra, within, Fr. dos, back), in architecture, the under-curved surface or soffit of an arch (q.v.).
INTRANSIGENT (adopted from the Fr. intransigeant, taken, through the Spanish intransigente, from the Lat. in, not, and transigere, to come to an understanding), one whose attitude is that of an irreconcilable. The term is used chiefly of politicians of an advanced type; those in complete antagonism to the existing form of government; but is especially applied on the continent of Europe to members of legislatures holding extreme Radical views. In this sense the word was first used in the political troubles which arose in Spain in the years 1873-1874. Intransigentism implies an attitude of uncompromising disagreement with political opponents. The word is also used non-politically, in the sense of intractability and intolerance.
