Tenni§. Oldest of all existing games of ball; was played in Europe in the Middle Ages, coming from Italy to France, and from France to England. The ball is thrown against a wall and struck by a racket on its rebound. It was formerly played in the open air, now generally in courts with walls, or with walls and roof.

Tennis, or Lawn Tennis. Game played by two or four players. It consists in driving a small felt-covered ball across a net so that it may strike within a certain prescribed area. The players take turns in serving, i.e., putting the ball in play; it must strike within a certain space of the opponent's court. After that, it may be struck on the fly, volleyed, or after the Ilrst rebound. A player failing to hit the ball, or hitting it and failing to place it over the net and within the confines of the opponent's court, loses the stroke.

It is partly absorbed by the atmosphere and partly transmitted directly through it into space; but that absorbed by the air is subsequently radiated by it, so that all terrestrial radiation eventually passes into space. Similarly, the heat communicated to the atmosphere by the sun directly or by convection from the earth's surface is eventually lost in space by atmosphere radiation. The sum total of radiation from land, ocean and air is terrestrial radiation in a general sense, and is just able to balance the solar radiation received.
