Сторінка 130 - If we compare the mean temperatures of places that differ considerably from each other in latitude, we shall find that the mean values are lower as we proceed north. If we compare the mean temperatures of places having the same latitude, we shall find that the mean value of those situated at the higher level will be less than those at the lower level. If we compare places having the same latitude, we shall find that the mean temperatures of those places situated inland will be higher in the summer...
Сторінка 243 - It has never been resolved into simpler or elementary influences, and may perhaps best be conceived of as an axis of power having contrary forces, exactly equal in amount, in contrary directions.
Сторінка 105 - Channel, as before observed, experiments have shown that, notwithstanding the variety of times of high water throughout the Channel, the turn of the stream...

Сторінка 240 - ... the intensity. This expression indicates a uniform intensity, so that there are no bands at all. Secondly, suppose p to increase algebraically in passing from the red to the blue. This will be the case in Sir David Brewster's experiment when the retarding plate is held at the side on which the blue is seen. It will be the case in Professor Powell's experiment when the first arrangement is employed and N is negative, or when the second arrangement is employed and N is positive. In this case w...
Сторінка 189 - Iguanodon would be 1 1 feet 5 inches ; which exceeds that of the Megatherium. If there be any part of the skeleton of the Iguana which may with greater probability than the rest be supposed to have the proportions of the corresponding part of the Iguanodon, it is the lower jaw, by virtue of the analogy of the teeth and the substances they are adapted to prepare for digestion. Now the lower jaw gives the length of the head in the Iguana, and this equals the length of six dorsal vertebrae, so that...
Сторінка 197 - Iguanodon, and the magnitude of the anterior outlets which gave exit to the vessels and nerves that supplied the front of the mouth, indicate the great development of the integuments and soft parts with which the lower jaw was invested. The sharp ridge bordering the deep groove of the symphysis, in which there are also several foramina, evidently gave attachment to the muscles and integuments of the under lip ; while two deep pits for the insertion of the protractor muscles of the tongue, manifest...
