The eclipse of Jupiter's 3d satellite on the 23d, which is set down in the 
Nautical Almanack, as visibleat Greenwich, will not be visible. Indeed 
the only one that is so, is the emersion of the first satellite on the 29th, 
which is not marked in the Almanack. Th¢ emersion of the third on the ~ 
9th at 15 17™ 24s ought to be 2h 17™ 24s

Sun’s Atmosphere. 
[From the Political Zeitung of Munich, of the 10th August. ] 
“The great and remarkable opening in the sun’s atmosphere 
of clouds (wolkigen sonnenatmosphare), of which notice has been 
lately taken, was visible only a little before it vanished at the 
western edge on the 5th of August, at which period a number of 
little openings began to unite themselves into two spots; storms 
and much rain followed. It must be of great utility to farmers 
to be able to foretel fair or stormy weather, from observations of 
the spots on the sun, which are easily examined in the middle of 
summer, in the same way as we can do for the coming day or 
night, by the rising and setting sun. A great number of the 
latest observations confirm Herschel’s opinion, that like the planets 
(verander lichen sternen) one half of the sun is less favourable to 
an abundant discharge of rays than the other, and that many spots 
on the sun make the year warmer and more fruitful. So much 
is certain, that in defect of spots on the sun, the atmosphere is 
more serene, as happened in the year 1811, in which none ap- 
peared during the whole summer; but it showed likewise that 
such a year must not of necessity be unfruitful, as was the case in 
the years 1795 and 1799. It is yet more certain that very warm 
and very cold weather can alone depend on the periodical abun- 
dance or scarcity of combustible matter (Lrennstoff) in the sun, 
since the moon and the planets can neither cause heat nor cold. 
In the year 541, which was one of famine and pestilence, the 
rays of the sun, according to Cedrenus, were as feeble as those’ 
of the moon, and yet the weather was so clear that in Italy they 
observed
