Ozone.

Prof. Mantogazza, of Pavia, has lately discovered that oxone is generated in immense quantities by all plants and flowers possessing green leaves and aromatic odors. Hyacinth, mignonette, heliotrope, lemon, mint, lavender, narcissus, cherry, laurel, and the like, all throw, off ozone largely on exposure to the sun’s rays. So powerful is this great atmospheric purifier, that it is the belief of the chemists that whole districts can be redeemed from the deadly malaria that jnfests them by simply covering them with aromatic vegetation. The bearing of this upon flower culture in our large cities is also very important, Experiments have proved that the air of cities contains less ozone than that of the surrounding country, and the thickly inhabited parts of cities less than the more sparsely built, Or than the parks and open squares. Plants, and flowers, and green trees can alone restore the balance; so that every little flower-pot is not merely a thing of beanty while it lasts, but has a direct and beneficial influence upon the health of the neighborhood in which it is found.
