Velloziese 
nous plants, of the order Amari/llidacea: It is 
characterized by a woody and usually branching stem, and 
by one-flowered peduncles, solitary or few together within 
a fascicle of leaves, usually with a persistent perianth, and 
with six to eighteen stamens. It includes about 58 spe- 
cies, classed in the 2 genera Vettoaa and Barbacenia, the 
latter entirely South American and the same in habit as 
Vellozia.

its velocity is measured by the space described by it in a 
unit of time, as one second. If the motion of the body is 
not uniform its velocity is measured by the space which 
it would describe uniformly in a given time if the mo

and many modified and improved kinds have become pop- 
ular under the name of bicycle. (See Also tricycle.) Light 
boats driven by a paddle-wheel or wheels operated by 
cranks and treadles, and known as water-velocipedes, have 
also been brought into use. See also cuts under bicycle

speed in movement ; swiftness ; rapidity ; celer-

See def. 2. 2. In physics, rate of motion; the 
rate at which a body changes its position in 
space ; the rate of change of position of a point 
per unit of time. The velocity of a body is uniform 
when it passes through equal spaces in equal times, and 
it is variable when the spaces passed through in equal 
times are unequal. The velocity of a body is accelerated 
when it passes constantly through a greater space in 
equal successive portions of time, as is the case with fall- 
ing bodies under the action of gravity, and it is retarded 
highly characteristic ciliated formation of the 
embryo, which serves as an organ of locomo- 
tion in that stage when the embryo is called a 
veliger. It is usually soon lost, but in some 
cases is permanently retained in a modified 
form. See cuts under velitjer. 4. In Hydro- 
zoa, a kind of flap or circular free edge which 
projects inward around the margin of the disk 
of many hydrozoaus, as those which are bell- 
shaped or conical, and which from its presence 
are called craspedote; a velarium. The velum 
is present in all well-developed hydromedusaus, but sel- 
dom in scyphomedusans, in which latter it is known as 
the pseudovelum. See cuts under Diphyidse and medusi- 
form. 
5. In Infusoria, a delicate veil-like membrane 
bordering the mouth in such forms as Cyclidium 
and Pleuronema. 6. In sponges, one of the 
transverse diaphragms or partitions which con- 
strict the lumen of an incurrent or excurrent 
canal. 7. In Eotifera, the trochal disk. See

woven silk stuff having a very thick and short 
pile on one side, which is formed by carrying 
part of the warp-thread over a needle, and cut- 
ting the loops afterward. Inferior kinds are made 
with a cotton back (see velveret), and are commonly called 
cotton-backed velvet*. Cotton velvets are also made. (See 
cottoni, and also velveteen.) These imitations and inferior 
qualities are so common that real velvet is commonly 
called lilk velvet or Lyons velvet to distinguish it from them.

Velvet (from It. velluto, "shaggy") had a silk weft 
woven so as to form a raised pile, the ends of which were 
cut or shaved off to one even level : hence it is also called 
in Italy raso. Encyc. Brit., XXIII. 210.

Also called tela choroidea superior and velum, triangulare. 
Velum pendulum, velum palati, velum palati- 
num, the veil or curtain of the palate ; the soft or pen- 
dulous palate, especially its posterior part, in many ani- 
mals prolonged into a pendent teat-like process, the uvula. 
(See cut under tonsil.) In cetaceans the velum forms a 
muscular canal which prolongs the posterior nares to the 
larynx, which it embraces, an an-angement bearing rela- 3 Monev gained through gambling: as, to

wall of the third ventricle, from the pituitary to the pineal work, a kind of needlework done by outlining the raised 
with cuticle and fur. It bears the same relation to 
the nutrition of the antler that periosteum does to that of 
bone. Its sloughing or exuviation follows the constric- 
tion and final obliteration of its vessels a process which 
is accomplished or favored by the growth of the bur about 
the base of the antler, which cuts off or obstructs the cir- 
culation of blood. The antler subsequently receives no 
nourishment, and is itself shortly afterward exuviated or 
cast as a foreign body. 
Good antlers "in the velvet" will sell readily for four 
dollars a pound in any part of Siberia.
