Over the parts that are becoming leaf-surfaces, certain of the materials are metamorphosed into wax. In this place starch passes into one of its isomeric equivalents, sugar; and in that place into another of its isomeric equivalents, gum. By secondary change some of the cellulose is modified into wood ; while some of it is modified into the allied substance which, in large...
Página 262 - ... theory. We have already hinted that Uranus, while revolving in the same direction with the other planets, has a backward rotation, so that to an observer placed upon Uranus the sun would seem to rise in the west and set in the east. His moons revolve about him in the same retrograde direction ; and his axis, instead of standing at a great angle to his orbitplane, as is the case with all the nearer planets, lies down almost upon the orbit-plane. It has been asserted that these peculiarities are...
