An Interesting Fact. The British Astronomer Royal, in his last annual report, referred to certain mysterious changes of level and direction of one of the instruments--one concurring with changes of temperature, the other with the equinoxes--and he imagined some movement of the earth itself to be the cause of these remarkable phenomena. Those who are acquainted with the perfection of the instruments used in the great observatories, the permanency of the direction of the transit and equatorial instruments, and the accuracy of measurements depending on their accuracy, will understand that these mysterious changes are in the highest degree important and astounding. Is the earth changing the inclination of its axis?
