or BALLON, in a general sense, signifies any spherical hollow body, of whatever matter it be composed, or for whatever purpose it be designed. Thus, with chemists, balloon denotes a round short-necked vessel, used to receive what is distilled by means of fire; in architecture, a round globe on the top of a pillar; and among engineers, a kind of bomb made of paliswood, and played off in fire-works, either in the air or on the water, in imitation of a real bomb. Air-Balloon. See Aerostation and Air-Balloon.
Balloon also denotes a kind of game something resembling tennis. The balloon is played in the open field, with a great round ball of double leather blown up with wind, and thus driven to and fro with the strength of a man's arm, fortified with a brace of wood.
Balloon, is more particularly used among voyagers for the state-barges of Siam. The balloons are a kind of brigantine, managed with oars, of very odd figures, as serpents, sea-horses, &c., but, by their sharpness and number of oars, of incredible swiftness. The balloons are said to be made of a single piece of timber, of uncommon length; they are raised high, and much decorated with carving at head and stern: some are girt over, and carry 120 or even 150 rowers on each side. The oars are either plated over with silver, or gilt, or radiated with gold; and the dome or canopy in the middle, where the company is placed, is ornamented with some rich stuff, and furnished with a ballustrade of ivory, or other costly matter, enriched with gilding. The edges of the balloon just touch the water; but the extremities rise with a sweep to a great height. Some are adorned with variety of figures, made of pieces of mother of pearl inlaid: the richer sort, instead of a dome, carry a kind of steeple in the middle; so that, considering the slenderness of the vessel, which is usually 100 or 120 feet long, and scarce six broad, the height of the two ends, and of the steeple, with the load of decorations, it is a kind of miracle they are not overflown.
the French paper-trade, is a term for a quantity of paper, containing 24 reams.

Ballota, white horsetail: A genus of the gymnophyta order, belonging to the didynamia class of plants; and in the natural method ranking under the 4th order, Verticillatae. The calyx has 5 teeth, with 10 stigmas; and the upper lip of the corolla is crenated. It is a common weed growing on the sides of banks in most parts of England, as also in walk-places near towns and villages in Scotland; so is seldom admitted into gardens. The flowers grow in whorls, upon branched peduncles, and lean on one side of the stalk; they are commonly of a dull red colour, but sometimes white. It was formerly used in hysterical cases, but is now fallen into disuse. The Swedes reckon it almost an universal remedy in the diseases of their cattle. Horses, cows, sheep, and goats, refuse to eat it.
