Страница 137 - The seeds of things seem to lie latent in the air, ready to appear and produce their kind, whenever they light on a proper matrix. The extremely small seeds of fern, mosses, mushrooms, and some other plants are concealed and wafted about in the air, every part whereof seems replete with seeds of one kind or other.

Страница 105 - In the case of an ordinary gaslight the best experiments show that not more than one or two per cent of the radiant energy consists of visible rays, the rest is either invisible heat or actinism ; that is to say, over ninetyeight per cent of the gas is wasted in producing rays that do not help in making objects visible.
