TALC, a species of fossil, found in England, Bohemia, Spain, &c. comprehending 3 varieties, namely : 1 . The Talcite, or Scaly Talc, is dug in small light scales, which adhere to tlie fingers : it is white, iiiterraixed with green ; and, when - rubbed on the skin, imparts a bright gloss. 2. The Fenetian, or Common Talc, is also white, interspersed with green or red veins. 3. The Schistose Talc is of a slaty nature, and a grey hue, spot- ted with white, green, or blue ; but, on exposure to the air, it be- comes white and scaly. This mineral is employed in pre- paring compositions for earthen vessels : on account of its smooth- ness, brightness, and un(Stuous «5^uality, it has l)een celebrated as a cosmetic ; and various unsuccess- ful experiments have been made, with a view to extra6t from it oils, salts, and other supposed ingredi- ents. — When combined^ with al- kalipe salts, it is fusible it) a strong heat, and forms a transparent, handsome, greenish-yellow glass ; if equal portions of talc and of chalk be melted together with one- fourth part of borax, the mixture -will produce a fine pellucid green- ish glass, which is of considerable lustre and hardness : gypsous earths may also with advantage be substi- tuted for the chalk, and the result will be a beautiful, pellucid yellow glass, of equal brightness and du- rability. — ^I'alc is subjeft, on im- jpottation, to a duty of 2|d. per lb. TAN [185 TALLOW, is the fat of certain animals, properly boiled and clari- fied. It may be procured from almost every creature, excepting worms and insefts ; though the best and largest qa;uitities are ob- tained from bullocks, sheep, hogs, andbeHrs. Considerable quantities of tallow- are consumed by salt-boilers, for the purpose of imparting a large grain to the salt : it is also used in the m;mufadure of soap, and particularly in making candles. By the 7 Geo. IIL c. 12 (conti- nued by sulwequent a6ts till 25th. March, 1806), tallow, or grease, including lard, may be imported from any part of Europe, free c£ duty} provided it be regularly en- tered and landed ; otherwise, it is subjed to the charge of 10s. id. per cwt. TAMARIND-TREE, oxTama- rindus Iiidica, L. a native of the East and West Indies, of America, Arabia, and Egypt, where it attains the height of 30 or 40 feet. The fruit of this tree resembles a bean-pod} is eight inches in length j and contains from 3 to 4 hard seeds, covered with a deep-brown viscid pulp, which is of a pleasant sub-acid taste. When taken in the quantity of from three drams to aa ounce, this pulp proves a gentle laxative ; at the same time allevi- ates thirst ; and mitigates immo- derate heat. Farther, it increases the operation of manna, and simi- lar sweet purgatives, while it weak- ens the action of the more drastic, and especially of resinous, drugs : hence it forms an useful ingredient in various medicinal preparations.— Tamarinds pay, on importation, 2|d, per lb.
