TELLURIC a.
ed from, or resembling, tellurium; specifically, designating those compounds in which the element has a higher valence as contrasted with tellurous compounds; as, telluric acid, which is analogous to sulphuric acid. Telluric bismuth (Min.), tetradymite. -- Telluric silver (Min.), hessite.
TELLURIDE n.
A compound of tellurium with a more positive element or radical; -- formerly called telluret.
TELLURIUM n.
A rare nonmetallic element, analogous to sulphur and selenium, occasionally found native as a substance of a silver-white metallic luster, but usually combined with metals, as with gold and silver in the mineral sylvanite, with mercury in Coloradoite, etc. Symbol Te. Atomic weight 125.2. Graphic tellurium. (Min.) See S…
TELLUROUS a.
ed from, or containing, tellurium; specifically, designating those compounds in which the element has a lower valence as contrasted with telluric compounds; as, tellurous acid, which is analogous to sulphurous acid.
TEMPER v.
To mingle in due proportion; to prepare by combining; to modify, as by adding some new element; to qualify, as by an ingredient; hence, to soften; to mollify; to assuage; to soothe; to calm.

TENUIS n.
aspirates, x, f, th. The term is also applied to the corresponding letters and articulate elements in other languages.
TERBIUM n.
A rare metallic element, of uncertain identification, supposed to exist in certain minerals, as gadolinite and samarskite, with other rare ytterbium earth. Symbol Tr or Tb. Atomic weight 150.
TERNARY a.
Containing, or consisting of, three different parts, as elements, atoms, groups, or radicals, which are regarded as having different functions or relations in the molecule; thus, sodic hydroxide, NaOH, is a ternary compound.
TETRADIC a.
tetrad; possessing or having the characteristics of a tetrad; as, a carbon is a tetradic element.
THALLIC a.
ved from, or containing, thallium; specifically, designating those compounds in which the element has a higher valence as contrasted with the thallous compounds; as, thallic oxide.
THALLIUM n.
A rare metallic element of the aluminium group found in some minerals, as certain pyrites, and also in the lead-chamber deposit in the manufacture of sulphuric acid. It is isolated as a heavy, soft, bluish white metal, easily oxidized in moist air, but preserved by keeping under water. Symbol Tl. Atomic weight 203.7.…
THALLOUS a.
ved from, or containing, thallium; specifically, designating those compounds in which the element has a lower valence as contrasted with the thallic compounds. [Written also thallious.]
THOMSONIANISM n.
An empirical system which assumes that the human body is composed of four elements, earth, air, fire, and water, and that vegetable medicines alone should be used; -- from the founder, Dr. Samuel Thomson, of Massachusetts.
THORIUM n.
A metallic element found in certain rare minerals, as thorite, pyrochlore, monazite, etc., and isolated as an infusible gray metallic powder which burns in the air and forms thoria; -- formerly called also thorinum. Symbol Th. Atomic weight 232.0.
THULIUM n.
A rare metallic element of uncertain properties and identity, said to have been found in the mineral gadolinite.
TIN n.
An elementary substance found as an oxide in the mineral cassiterite, and reduced as a soft white crystalline metal, malleable at ordinary temperatures, but brittle when heated. It is not easily oxidized in the air, and is used chiefly to coat iron to protect it from rusting, in the form of tin foil with mercury to for…
TISSUE n.
One of the elementary materials or fibres, having a uniform structure and a specialized function, of which ordinary animals and plants are composed; a texture; as, epithelial tissue; connective tissue.
TITANIUM n.
An elementary substance found combined in the minerals manaccanite, rutile, sphene, etc., and isolated as an infusible iron- gray amorphous powder, having a metallic luster. It burns when heated in the air. Symbol Ti. Atomic weight 48.1.
TITANO- n.
(also used adjectively) designating certain double compounds of titanium with some other elements; as, titano- cyanide, titano-fluoride, titano-silicate, etc.
TITANOUS a.
Designating certain compounds of titanium in which that element has a lower valence as contrasted with titanic compounds.
