Seen in the proper light, the plainest function shows a spirit of worth and vigour, which far transcends its form— an essence needing only the clothing of a name to give it universal importance.

The author then publicly stated that there could be no longer a doubt that two planets exist beyond the orbit of Neptune, one about 100 times, the other about 300 times the distance of the earth from the sun, with periods of revolution of about 1000 and 5000 years respectively.

Page 6 - ... JUPITER AND HIS FIRST SATELLITE. — A series of observations of spots and markings on the planet Jupiter were communicated to the Royal Astronomical Society at the November meeting by Mr. Barnard. A careful study of numerous details observed during a period of twelve years has led to the conclusion "that the red colour of any of the markings is an indication of their age ; or in other words, when a spot or marking (other than the white spots) first appears it is dark or black, but after some...
