How Fruits Breathe.—It is well known that researches have been made on the respiration of plants. M. Calours has recently investigated the respiration of fruit, deeming it an important part of the physiology of vegetation; and he finds that ripe apples, oranges, and lemons, respire by consuming a portion of the oxygen of the atmosphere in which they are placed, and giving off an equivalent quantity of carbonic acid. Darkness diminishes, and diffused light increases the amount of carbonic acid, and it varies with alternations of temperature. But when once decomposition sets in, the quantity of carbonic acid is rapidly increased.—Chambers' Journal.
