Termites. White ants of the tribe Corrodentia, suborder Pseudo-neuroptera. They possess a pair of 18 to 20-jointed antenna?, a pair of ocelli as well as compound eyes, strong mandibles, and delicate wings, which lie parallel to the body when at rest. They live in communities, in passages hollowed out in wood, trees, mounds of earth, or nests of clay. Each colony has a queen, or sexually mature female, a king also,
according to some authorities, and neuters of two sorts; viz.. soldiers, with large heads and powerful jaws, and workers, with shorter head and broader abdomen. The workers are larvae of both sexes. Only the mature sexual forms have wings, but these organs are lost by the queen after copulation. Africa and S. America are the principal habitats. See Complementary Males And Females.

Terrestrial Paradise. Mediaeval writers fix the location of the Terrestrial Paradise in e. Asia. Cosmas in the 7th century speaks of it as a continent e. of China; others regard it as an island s.e. of Asia, while by some it was fixed in China. Later we find it described as an island s. of India or in Armenia, and frequently as Ceylon. In the center was a fountain that watered it, near which grew the tree of life. These notions are largely drawn from the Book of Genesis but similar conceptions are almost universal.
Terrestrial Radiation. Loss or radiation of heat by the earth into space, determined by Maurer to be 0.13 calorics per sq. centimeter per minute; heat radiated from the surface of land and water. It is partly absorbed by the atmosphere and partly transmitted directly through it into space; but that absorbed by the air is subsequently radiated by it, so that all terrestrial radiation eventually passes into space. Similarly, the heat communicated to the atmosphere by the sun directly or by convection from the earth's surface is eventually lost in space by atmosphere radiation. The sum total of radiation from land, ocean and air is terrestrial radiation in a general sense, and is just able to balance the solar radiation received.

TESTING MACHINE—TETRABRANCIII ATA
Testing Machine. Apparatus by which known or measurable stresses can be applied to specimens of materials or members of structures, for ascertaining experimentally their resistance to such strains. The usual types of machine are to apply tests in tension, in compression, in flexure, or in torsion. One type can usually make the first three investigations; torsion requires a special but inexpensive machine for the best work. The older testing machines loaded a pan with direct weights and multiplied their effect by levers which applied the multiplied load to the specimen; recent ones use either the hydraulic press or screw searing to produce the load upon the specimen, that load passing through the sample and being balanced by counterpoises upon a graduated scale beam. The counterweights on the scale beam can thus be regarded as applying the load through the multiplying levers as before, the
strain gearing being used only to neutralize deformation as it occurs. There are therefore two types of testing machine with respect to the applying of strain, hydraulic and screw. The hydraulic machines have the advantages of working easily by hand and rapidly, and of easy release of load for determining elastic limit; they are not so well adsrted to keep specimens under prolonged strain. The screw machines are adapted for use by power, with slow and gradual increase of strain and its prolonged maintenance. The torsional machines twist the prepared specimen by worm gear, and record the strain by the deflection of a loaded pendulum. The best machines give an autographic record of the test of specimens, a tracing point usually indicating elongations as abscissas upon the loads as ordinates. The largest machines are of the hydraulic type. The most perfect one ever built is the Emery Machine (q.v.). The most powerful machine is that at Phoenixville, Pa.; its capacity is 2,160,000 lbs., and it can break a bar 45 ft. long.
Testis (testicle). Essential reproductive gland of a male animal; in it, the spermatozoa are developed. In its most perfect condition of development a testis consists of a number of chambers or lobules, in each of which lie several coiled tubules (in Man, ab.800 each 2 ft. long). In the walls of the tubules the spermatozoa are formed by multiplication and transformation of epithelial cells. The tubules empty by means of a few straight tubes into a network of tubes from which in Man there are ab. a dozen vasa efferentia uniting to form the vas deferens or sperm duct. The latter in Man is ab. 20 ft. in length coiled up into an epididymis, and thence passing by a length of 2 ft. to reach the urethra. Testes are always paired and are developed and originate in the body cavity in a position corresponding to that of the ovaries, i.e., near the kidneys. In most Mammals they slip backward through the inguinal canal into scrotal sacs of the skin at the external opening of the urino-genital sinus. In the elephant, most Edentates, and lower among Mammals and all other Vertebrates, they never leave their primitive position. In Rodents and Inseetivora they descend through the inguinal canals only during rutting.
Test Oath. Generally, affirmation of present loyalty to a government. If so imposed as to be ex post facto in effect, it is unconstitutional in the U. S.
Tcstudlnata. Broadly, all the Chelonia (q.v.); in a restricted sense, the Testudinidce.
Tcstudinida?, or Chersidvb. Land Tortoises, a family of Chelonia. having high arched carapace, under which the head and feet can be retracted. The feet have separate
toes, and are adapted for walking. They are strictly herbivorous. The Emydidce are, by some, included as a subfamily. Examples of the family are the large and strong Gopher-tortoises of the Carolinas, which burrow in the earth, the massive Amazon Tortoise, used for food by the natives, the Galapagos Tortoise, and the small Garden Tortoise of Europe, also used as food.
Tetanus. Disease characterized by the continuous spasmodic contraction of certain muscles. Frequently the muscles of the jaws; whence the common name, lock-jaw. The origin is now traced to the presence of a specific microbe: the bacillus of tetanus. It usually is associated with an infected punctured wound, as the puncture of a rusty nail. It is one of the diseases where serum therapy seems to be curative, the results of the injection of tetanus antitoxin being very satisfactory as far as there has been opportunity to use it. Prevention is" far better than to risk the employment of the remedy, hence every punctured wound should be enlarged by a free incision to give an opportunity to properly cleanse the wound. If this is done promptly and thoroughly, tetanus will not ensue. Tetanus should not be confounded with tetany, which is also a disease of tonic spasm, but not so serious in its manifestation, nor is it due to an infection.

Texas. Largest of the States, on the Gulf of Mexico: area 265,780 sq. m. Stretching over 13 degrees of longitude and 10 of latitude, it contains all variations of surface and of climate. The e. part, along the Gulf coast, is low, marshy, and unheal thful. Further inland, it becomes higher and densely forested. Still further inland is a prairie region, more broken than the prairies of Illinois. This is succeeded by high arid tablelands, reaching their summit in the Llano Estacado, 3,500 to 5,000 ft. high; between, the Pecos and Rio Grande desert plains are intersected by short isolated ranges of mountains. Numerous rivers rise in the Llano Estacado and in the prairie region, and flow s.e. to the Gulf. Along the s.w. border, separating it from Mexico, flows the Rio Grande. Its principal branch is the Pecos, which joins it in the w. deserts. The geology of the State is ;is varied as its surface. The w. two-thirds are underlaid by Cretaceous formations, within which are found areas of Cambrian, Silurian, Carboniferous, and even Quaternary beds. Shoreward from this area of Cretaceous is a broad belt of Eocene, followed by Neocene, while along the Gulf, including all the low-lying country, are Quaternary beds. The industries differ widely in its different parts. In the e. the culture of cotton prevails; further w. that of the cereals as far as comparatively dense settlement has extended. Beyond that, on the w. and s., the ranging of cattle and sheep is the chief industry. In 1890 the value of farms was $399,971,289, of the agricultural product $111,699,430. In recent years the development of the railroad system of T. has gone on with extreme rapidity. In 1893 the mileage of railroads was 9,088. The State has not yet reached the stage of settlement where manufactures become of great importance. 585.000 tons of coal was mined in 1896. Its commerce is largely centered at the port of Galveston, and consists mainly of the shipments of cotton and cattle. Till 1821 the history of T. is that of a Spanish territory. After the purchase of La. by the U. S., Americans began to settle in T., and in 1821, when Mexico became independent of Spain, colonization from the U. S. was permitted and protected by the Mexican
government; but in 1830 the American colonists were placed under military rule, and hence ensued the struggle for independence. The Mexicans were defeated 1836, and till 1845 T. was an independent State. In 1845 it was admitted, against the protest of Mexico, as one of the States. The result was a war, ending in Mexican defeat, the cession of Cal., New Mexico, and the intervening territory, now composing Nevada, Utah, and Arizona, and the payment of $15,000,000. T., on admission to the Union, sold to'the U. S. the portion of its territory between the headwaters of the Rio Grande and Arkansas. The State seceded 1861, and was readmitted with a new constitution 1868. Capital, Austin. Pop., 1890, 2,235.523, over one-fourth colored.
