I a the basic tellurate montanite, Bi 2 (OH) 4 TeO 4; the silicates eulytite and agricolite, B14(S104) 3; and the uranyl arsenate walpurgite, Bi(U02)3(OH)24(As04)4.
It is decomposed by water with formation of tellurium and tellurous acid: 2TeC12+3H 2 0=Te+H 2 TeO 3 +4HC1.
Two oxides of the element are definitely known, viz., the dioxide, Te02, and the trioxide, Te03, whilst a monoxide, TeO, has also been described.
Tellurous acid, H 2 TeO 3, is obtained when the tetrachloride is decomposed by water, or on dissolving tellurium in nitric acid and pouring the solution into water.
It also gives rise to super-acid salts, such as KHTe03 H2Te03; K 2 TeO 3.3TeO 2.

We hear, too, of corporeal days and years, corporeal virtues, and actions (like walking) which are bodies ((Teo yam) Obviously, again, the Stoic quality corresponds to Aristotle's essential form; in both systems the active principle, " the cause of all that matter becomes," is that which accounts for the existence of a given concrete thing (Xoyos Ti s ov61as).
