Year 5365, March 3. Much interest has been 

 aroused by the observation that the motion of Gamma 

 shows a perceptible acceleration, directed towards our 

 system. A corresponding acceleration of the motion 

 of Grean has been proved to exist by numerous fixed- 

 star observations. 



June 12. The acceleration of the proper motions 

 of Grean and Gamma greatly exceeds that attri- 

 butable to gravitation. It is now supposed that 

 Gamma has acquired an extra planet, thus giving 

 it a negative charge sufficient to account for the 

 force. 



Year 5366, Aug. 1. Gamma is now seen to 

 show a perceptible disc. Its distance is estimated 

 at 10 18 cm. 



Sept. 15. Gamma is now seen as a large star 

 with at least two outer planets. The innermost of 

 these is retrograde, with considerable eccentricity. 

 It has been provisionally identified with the new 

 planet of 5285. 



Year 5367, April 30. There is every likelihood 

 of our being converted into a binary. The elements 

 of Gamma indicate an elliptic orbit round our 

 common centre of gravity. 



Aiig. 25. Gamma is now fully visible with the 

 naked eye as a sun one-tenth the diameter of Grean. 

 The two are now in opposition, and there is per-
