A Land Tide.

Recent observations with the seismographs at Mauritius have led to (be suggestion that not only the ocean and the atmosphere, but even the land, may experience the effects of a dally tide running round and round the earth as it revolves on Its* axis. Bat while the tides In the air and the sea are due more to the moon than to the sun, the supposed "land tide” arises Bolely from the sun’s action. Moreover, It is caused, not by the attraction of the snn, hut by its heat. A ware of depression is supposed to follow the sun from east to west, caused by the extraction of moisture from the soil At Mauritius it Is found that there is a relative upheaval of the land to the west of the place of observation from morning until evening, and a relative depression on the same side, or an unheaval to the east, during the night.
