On the 4th inftant, about one o'clock p. m. was a very tremendous ftorm of thunder, hail,,

ASTRONOMICAL ANTICIPATIONS FOR AUGUST, 1809. 
We shall have a new moonon the*1ith of this month, at 33 minutes past seven, morning $. 
and a full moon on the morning of the 25th, at 3 minutes past seven. The new planet 
Herschel or Georgium Sidus, may be seen in the evenings, if the weather permit. On the 
evening of the 1st, he sets at 25 minutes past ten, onthe 11th, at 47 minutes past nine, on. 
the 21st, at LO minutes past nine, and on the Sist, at 55 minutes past eight. Saturn may. 
also be seen in the evenings, in the S. W. about two-thirds of a sign to the east of the Geor- 
gium Sidus. Qn the 2d, he will be stationary in 27° 15’ of the sign Scorpio, at which time 
he will be very nearly in conjunction with the 6-of the Balance, a star of the fourth magni- 
tude, the difference of latitude being only 1% 31’, the star being to the north~ On the 
morning of the QJst, at two, he will be in quartile aspect with the Sun. Jupiter may be seen 
{if clouds interpose not,) almost the whole night, as he rises within three hours aftersun-set. 
To an eye unassisted by the telescope, he will appear throughout this month, in respect to 
the fixed stars, as if completely deprived of motion. For the first 15 days, he will move . 
— slowly forward, or according to the order of the signs, in all that time scarcely advancing 
-third of adegree. On the 15th he willbe stationary in 243. 55’ of the sign Aries; after 
ane he will become retrograde, moving back in almost the same track he had beeh ad- 
vancing in during the first half of the month. Some visible immersions of the-first and second 
satellite of Jupiter will take place this month. The immersions of the ist will be- 
on the morning of the 2d, at 9 seconds past three 5. on the night of the 10th, at 22 minutes. 
& seconds past eleven; on the morning of the 18th, at 45 minutes 59 seconds past one; on the 
morning of the 25th, at 9 minutes 49 seconds past three; and on the evening of the 26th, at 3% 
minutes 18 seconds past nine. The immersions of the second satellite happen on the night of the 
19th, at Si minutes 4 seconds past eleven; and on the morning of the 27th, at 8 minutes 36 
seconds past two. It must be observed. that the above immersions are set sorers to clock time. 
The planet Mars may be seen in the evenings for two or three hours afrer sun-set. On the. 
3th, there will happen a notable conjunction of this planet with the Georgium Sidus, well 
worthy the attention of the curious. The exact conjunction will not be visible in Great. 
Britain; but on the evening of the 5th, when it is dark enough to observe them with advan-' 
tage, Mars will be aly about ten minutes of a degree past the conjunction, and the difference 
of latitude only 10 36’, the planet Herschel being to the north. ‘The above conjunction will 
be of creat service to the inexperienced astronomer, who has not yet had a sight of the new. 
planet. Venus will be up every morning about four hours before sun-rise. Her greatest 
elongation happens.on the 2d, at which time she will bé 45° 40’ tothe west of thesun. In 
the first part of the month, Mercury may be seen in the morning; yet it will be with 
considerable difficulty, on account of the long duration of the twilight. 
His superior con- 
junction with the sun takes place on-the forenoon of the 25th at eleven.

TO CORRESPONDENTS. é 
J.M. of Dunbartonshire, will observe, that, by an inadvertency of the Printer, his 
Leiter of enquiry about. his Comnunication, has been inserted enstead of the Communi- 
cation itself. An apology is due to all our readers for so gross a blunder ; and.J. M. 
2s informed, that his original papers shall be inserted in our next Number. 
Wehave received on wnteresting 
Knowledge during the last.twenty yeurs, made to the emperor Napoleon by the classes 
of the National Institute. It will occupy five or six pages of the four or five next 
Numbers ; but the value and interest of thematter will compensate for the extraordj- 
nary length of the article. 
Our Readers will feel that the new department, Scarce Tracts, is likely to add 
@ery to the interes “of this Magazine; and it ws in the power of most of our Core 
Spondents to contribute something of this kind highly valuable and CUTOUT.
