TENNIS, a play requiring muscular exertion, and at which a ball is driven, by means of a racket.
This game is of French origin, and was introduced into Britain in the 17th century: it is performed in a long court, denominated a tennis-court, across which a net is suspended: through the latter, the ball is stricken by a racket; and, accordingly as it is driven into certain galleries, the game is lost or won.
Tennis is played by sets, each of which comprehends six games; but, if an advantage-set be proposed, 7 successive games must be obtained, by one or other party.—As, however, our limits will not permit us to enter into particulars, the inquisitive reader may consult Mr. Hoyle's "Games Improved," by Mr. Beaufort (12mo. 3s.), in which the rules of tennis are fully explained.

TERRIER, or Canis terrarius, a variety of the dog-kind, which is of different colours, being sometimes spotted, though generally of a liver, or black hue: its body seldom exceeds 18 inches in length, and the head is embellished with short, smooth, pendent ears.
Terriers are very useful to agriculturists, especially for exterminating rats, pole-cats, and similar depredators. Farther, these animals are remarkable for their vigilance, and are therefore frequently employed as house-dogs; but their principal services consist in hunting badgers, foxes, rabbits, and other quadrupeds which burrow under ground; because they enter the holes of such wild creatures, and either kill or draw them out of their hiding-places.—An account of the diseases to which terriers are liable, the reader will find in the article Dog.
TERROR, or the apprehension of an evil which we are unable to prevent, is one of the most destructive passions inherent in mankind.
Persons of weak nerves, and those who possess a high degree of sensibility, are most frequently subject to the influence of this tormenting passion: hence they are more severely attacked than the robust or phlegmatic; and the only certain method of preventing ill consequences is, that of avoiding every occasion that may tend to re-produce such disastrous impressions.
Terror contracts every muscle, and induces violent palpitations of the heart, spasms, and fainting: the usual evacuations become obstructed; cutaneous eruptions are repelled to the interior organs more essential to life; the whole system is deranged; violent convulsions, fits of epilepsy, and sudden death, are its frequent effects, especially during and after debilitating diseases.
As this passion is productive of such dreadful consequences, it will be advisable immediately to adopt the treatment generally followed in spasmodic affections. Thus, vinegar, spirits of hartshorn, lavender, or other stimulants, are to be held to the nostrils: a little warm tea, or wine and water, may be given to the patient; his feet and legs should also be plunged in a tepid bath; and the suppressed evacuations ought to be speedily restored. The most important object, however, is the recovery of mental tranquillity: for, unless the mind be composed, external
