Another Keiv Planet . 2&1 



throw some new light- upon some other phenomenon. 

 From the new theory there resuhs already the decision of^ 

 an important point in meteorology. Opinions were divided 

 upon the method of estimating the height of mercury in the 

 barometer. The one party reckoned from the base, and the 

 other from the summit of the convexity. This last method 

 is much less inaccurate, but it still gives heights that are 

 less than those which result from the pressure of the atmo- 

 sphere j the difference is the effect of the capillary action. 

 In order to correct it, the author points out two methods: 

 one of which is analytical ; the other, which will no doubt be 

 preferred by the greatest number of observers, only rests upon 

 an easy experiment and a very simple and short calculation. 

 By one or other of these means^ results will be obtained 

 more precise, more certain, and which may be more easily 

 compared.

ANOTHER NEW PLANET. 



M. Olbkus has discovered a new planet, being the second 

 which wc owe to the observations of this learned and inde- 

 Jatigabie astronomer. Tlie folluwing was nearly its situa- 

 tion: On the 29th of March at 8'' ^l-", iT)oan time, 1S4'' 8"; 

 northern declination, 11<'47'"; on the 30th of -March at 

 12'*33"', mean time^ IbQ- 5 2'- ; northern declination, ll' 

 54"^. 



This new planet v.-as found and observed by Stephen 

 Groombridge, esq. at his observatory on Blackhcalli, iiorn 

 the account transmitted from the Continent. Mr. Groom- 

 bridge says, it appears as a star of the sixth magnitude, of a 

 dusky white colour, very like in its appearance to the 

 Georgium Sidus. Observed in the meridian of Mr. (iroom- 

 bridge's observatory, Blackhealh, the follov.ir.g were its 

 positions on the 25th and 2Glh inst.
