It would be difficult to say with certainty on what day the 

 comet will become visible. The state of the heaven, the power 

 of the instruments, the goodness of the power of sight of the 

 observer, united to physical causes, already mentioned, varia- 

 tions of intensity} render all attempts to solve the problem en- 

 tirely illusory. M. Olbers believes that at its maximum of 

 lustre, the expected comet, far from surpassing, as has been pre- 

 tended, that of 1811, will not equal the third comet of 1825, 

 which the public allowed to pass without paying any attention 

 to it. 



It is towards the middle of October, that the comet of Halley, 

 during its next appearance, will be nearest the Earth. We may 

 add that its distance will never be less than eight millions of 

 leagues, of twenty-five to the degree. Thus those who have 

 not been entirely reassured by the numerous pleadings publish- 

 ed lately in favour of comets, cannot in the present case have 

 any plausible cause of uneasiness. 



On the periods of the Deluges of Deiccalion, Ogyges, and Noah, 

 according to the various calculations of time of different 

 Nations. By Dr Von Schubert. 



The history of nations and countries speaks distinctly of 

 several partial floods and deluges which seem to have been pro- 

 duced by lakes at a high elevation bursting through their bar- 

 riers. The flood of Deucalion, and also that of Ogyges, have 

 been considered as having owed their origin to the outbreak 

 of highly situated masses of water (as, for example, of the Thes- 

 salian lake), and they are supposed to have taken place several 

 centuries after the great Noachian Deluge. A more accurate 

 comparison of the various chronological dates, shews that the 

 ancient calculators of time understood no other than the flood 

 of Noah by the floods of Ogyges and Deucalion. This was in-
