TRICHINA

TRINITY COLLEGE

Trichina (tri-kt'nd), a minute worm, parasitic in the muscles of swine and some other animals and very dangerous, since it can be transferred to man. The transformation comes by eating raw or imperfectly cooked pork. This worm (Trichina spiralis) was discovered in 1835 by Richard Owen. Jt is about one twenty-fifth of an inch long. Vv hen quiet, it lies coiled in a capsule or cyst within the muscles of the infected animal. When infected meat is eaten by man, the capsules are dissolved within the stomach and the worms set free An immense number of new and very minute worms are soon produced — each female being able to supply 1,500 to 2,000 eggs. The newly hatched worms bore through the walls of the intestines and get into the blood-vessels and lymphatic passages, and are thus carried all over the body. They make their way from the blood-vessels into the muscles, and there become full-grown and inclosed in capsules. From that time they are quiet, and, if the patient can survive the period of migration, he recovers. The connection of this worm with the disease was made known about 1860 by Leuckart, Virchpw and others. It is difficult to say how swine become infested, but, the worm is found in the rat, and as these are about slaughterhouses and sometimes eaten by pigs, the infection may come in that way.

Trichogyne (tr%k''o-ftn), (in plants), a tubular, hair-like process developed from the female organ (carpogonium) of the red seaweeds. See RHODOPHYCE^.

Trichome(*r£#'dm), (in plants), a general term applied to outgrowths from the epidermis, chief among which are hairs. See HAIR.

Trieste (tre-es'td), a seaport of Austria (q. v.), at the head of the Gulf of Trieste, on the Adriatic Sea, 90 miles northeast of Venice. There is an old town, with narrow streets and black walls, built on the slope of a hill and surmounted by a castle. Its cathedral has stones with Roman inscriptions built into its walls and a tower resting, it is said, on the foundation of a temple of Jupiter. The new town, on the plain toward the sea, is a handsome city with a fine harbor. There are extensive manufactures for making soap, rope, white lead, wax and leather. The people are Germans, Italians, Greeks, Jews and Dalmatians, but the majority speak Italian. Trieste, as Terg^ste or Tergestum, was plundered by neighboring tribes as early as 51 B. C. In 1382 it passed into the hands of Austria. Population 229,475.

Tri'lobite, among fossils, any individual of the order Trilobita, so called from the division of the external skeleton into three regions. These comprise a cephalic shield or head; a variable number of body-rings; and a caudal shield or tail. They vary greatly in size, some being scarcely larger than a pin's head, while species of Asaphus

have been met with that are two feet in length. They appear to have lived in shallow water, feeding on small marine animals. They are found in large numbers in the paleozoic system of rocks.

Trinidad (trtn'l-d&d'), the most southern of the West Indies, lies off the coast of Venezuela, nearly opposite the mouth of the Orinoco. It is 50 miles long and from 30 to 60 wide, and includes 1,754 square miles. The two channels to the harbor are called the Dragon's Mouth and the Serpent's Mouth. On the northern coast are forest-covered mountains, one with two peaks, called Tamana, while the rest of the island abounds in fertile valleys and plains. There are some good-sized rivers and several fine harbors. A lake, with pitch floating on its surface, is one of the curiosities of the island. (See ASPHALT.) The most important products are cocoa, sugar, rum, molasses, coffee, cotton, coeoanuts and oil. There are 250 public schools, with 40,956 pupils, many private sclliools, Queen's Royal College and a Roman Catholic College, with a total of 427 students. The chief town, Port of Spain, originally built of wood, was burned in 1808. The new town, built of stone, is one of the finest in the West Indies. The island was discovered by Columbus in 1498 and named Trinidad, because he first saw three mountain-summits from his ship. In 1797 it was taken by the British from the Spanish, and in 1889 Tobago was annexed. It has 81 miles of railway and 1,147 of telegraph and telephone. There are steamship lines to England, Holland, North America and Ven-ezula. Population 330,074.

Trinidad, Colo., a city, the seat of Las Animas County, in the eastern foot-hills of the Rocky Mountains, on Las Animas River, and on the Denver and Rio Grande; Atchi-son, Topeka and Santa Fe*; and Colorado and Southern railways, 85 miles south-southeast of Pueblo. In the vicinity there is a good farming and cattle-raising country, and it is rich in coal, and produces much livestock, alfalfa, beans etc. It has good municipal buildings, churches and schools, a public library, an hospital, an academy and an attractive park. Besides its coalmines, railway-shops, foundry and ice-plant, it has a wool-scouring mill, a brewery, a cigar-factory, a brick-yard and bottling works. Population 10,204,

Trinity College, Toronto, Can., was founded by Bishop Strachan to secure for the youth of the church the best secular education in the arts and sciences combined with the religious teaching of the Church of England. By the generosity of churchmen in Canada and in England a liberal endowment was raised and a building erected in 1851. The college was formally opened in 1854, and its patrons laid stress on "the inestimable advantages of residen-
