TUAR1CK, a numerous people of Central Africa, occu¬ 
pying all the territory to the west and south of Soudan, and 
as far as the country on the Niger. They are tall, erect, and 
handsome, with an imposing air of pride and independence. 
Their skin is generally white, except in those parts that are 
exposed to the climate, which are of a dark brown. The 
most remarkable feature in their costume consists in a piece 
of glazed cotton cloth, generally blue, with which they cover 
their faces as high as the eyes, and which hangs down on 
the breast below the chin. Not to interfere with this, the 
beard is generally clipped very close. They wear turbans, 
generally blue, surmounted by high red caps ; while the body 
is generally covered with a loose shirt of blue cotton. Their 
swords are straight, of great length, and wielded with much 
ease and dexterity. From the left wrist is suspended a dag¬ 
ger, without which no Tuarick is ever seen : he wears also a 
light elegant spear of iron, and sometimes of wood. Their cou¬ 
rage and skill in the use of their weapons, causes them to be 
much dreaded ; and small bodies of them even traverse po¬ 
pulous and hostile countries without fear of molestation. 
They ride on a light and very swift species of camel, called 
maberry or heirie, which they manage with great dexterity, 
and which trot for many hours together, at the rate of nine 
miles an hour. Among the most powerful tribes of Tuarick 
are the Ghraat, who inhabit the neighbourhood of Gadamis; 
the Kolluvi, who possess the powerful kingdom of Asben, of 
which Agades is the capital; and the Tagaina, who imme¬ 
diately border on Soudan.

appropriated also to several things of the fungus tribe. Its

order fungi, natural order fungi,— Essential Character. 
TUB 
Roundish, fleshy, solid, closed; its substance variegated 
with veins bearing seeds. 
1. Tuber cibarium, or common truffle.—Blackish, rough 
with prominent warts.—Found under the surface of the 
ground in most parts of Europe, where the soil is light and 
dry; as well as in Japan, and the East Indies. Dogs are 
taught to find this fungus by the smell, and to scratch it out 
of the earth. It is brought to table. The size of this fungus 
is about that of a walnut in its outer coat, but the surface is 
irregularly tumid, and harsh to the touch from innumerable 
sharp warts. The inner substance is greyish, or pale brown, 
with numerous curved branching veins,’ lodging the minute 
seeds. No signs of a root are observable. There are said 
to be several varieties of colour in this species. 
2. Tuber moschatum, or musky truffle.—Blackish, smooth. 
—Native of France. 
3. Tuber griseum, or grey truffle.—Roundish, irregular, 
smooth, soft, greyish-ash-coloured.—Native of Piedmont, in 
a light, moderately moist soil. The size of the two precedr 
ing, but more irregular in shape, of a soapy texture and 
light colour, with a strong scent of garlic. 
4. Tuber album, or white truffle.—Light reddish-brown, 
roundish, half above ground; veins rusty-coloured.—In 
woods, in England and France, also in Greece, but partly 
sunk in the earth. Its flavour is disagreeable. 
5. Tuber asstivum, or summer truffle.—Nearly globular, 
smooth, brown, or blackish; spongy within; entirely sub¬ 
terraneous—Plentiful in Carinthia and Carniola from May 
to August. These have little taste or smell, but are used 
much tor the table. 
6. Tuber cervinum, or bastard truffle—Globular, finely 
granulated, rather solid, finally bursting; powdery in the 
centre.—Found barely sunk in the ground, in several parts 
of England, as well as in Bohemia and Silesia, about Sep¬ 
tember. 
7. Tuber solidum, or hard truffle.—Globular but com¬ 
pressed, brown, reticulated, very firm ; blue-black within.— 
Found in Dr. Withering’s park at Edgbaston, near Birming¬ 
ham, uuder an oak-tree by the pool, in August. This had a 
short root, as Vaillant represents it, and appears to be, as Mr. 
Sowerby supposes, only a nearly sessile variety of his Lyco- 
perdon defossum, Engl. Fungi, t. 311. 
8. Tuber radicatum, or rooted truffle.—Roundish, de¬ 
pressed, cracked in the surface, with a thick short root.— 
Found on heaths, and in woods, in Italy and England in 
the summer, but rare. Two or three inches in diameter, 
solid, never bursting, nor becoming internally powdery. 
TU'BERCLE, s. [tuberculum, Latin.] A small swell¬ 
ing or excrescence on the body ; a pimple.—A con¬ 
sumption of the lungs, without an ulceration, arrives through

county of Londonderry; 9' miles north-north-west of

TUBEROSE, s. A flower.—The stalks of tuberose run 
up four feet high, more or less; the common way of plant¬ 
ing them is in pots in March, in good earth. Mortimer. 
TUBEROUS, adj. [tuber, Lat.] Having prominent 
knots or excrescences.—Parts of tuberous hcematitae sherv 
several varieties in the crusts, striature, and constitution of, 
the body. Woodward.
