( Tisen to 28,9. 30. 
The quantity of rain fallen thts month is equal to 4*2 inches in abe Rainy as the 
month has been, the moft ftriking and important feature is that of fhow. Weare apt un- 
doubtedly to forget the events of pa{ft years, and on that account we cannot compare what 
is prefeut with what is gone ty, fo accurately as could be withed, or we might be inclined 
to affirm that fo much fnow has not fallen im any winter thefe fifteen years, near the metro-~ 
polis, as we have experienced during the laft five weeks. Once in the month the froft was 
fo fevere as nearly to cover the Thaines with ice. It then began to thaw, and the effets 
of the froft and fnow fubfided very gradually: but the fall of {now from the 20th to the 
23d was by much the greateft, and the thaw came on in the morning of the 24th and cons 
tinued during the whole of that and the following day fo rapid as to occafion between this 
place (Highgate) and town very remarkable fioods. In feveral parts of St. Paneras, carts 
have plyed the whole of this day (25th) to carry paffengers from one place to another. 
We fear the thaw, which, has been accompanied with rain, muf be productive of much fe+ 
rious injury in many parts of the country. 
We have obferved above that the greateft variation in the thermometer m any one fpacé 
of 24 hours is 9°, This is the cafe fuppofing the obfervations to be made at ftated hour's ; 
buta much more remarkable variation happened between the evening of the 22d and mern- 
ing ofthe 25d. On Sunday morning the 2¢d the thermometer was 28°, tnow fell the whole 
day, but the temperature gradually increafed, and about ten at night itrained, and the mer 
cury was at 35°, but at fix or feven o’clock on the 23d it had fallen to 18° making @ dif- 
ference of 17° in the courfe ofa fingle night of eight hours. 
The average temperature for the month is equal to 339.13 which is lower than it has 
been for feven years for the fame month: and the mean height of the barometer is 29.3 
early, which must be regarded as very low. 
The wind has blown chiefly from the Eafterly quarters. Only four days in the thirty- 
one can be reckoned brilliant, on 15 there has been rain often in larger quantities, and oh 
eight there has been fnow. 
Astronomical Anticipations. 
The meon will be in conjunction with the Sun in the afternoon of the 14th at 59 minufés 
paft one. On the evening of the 27th will happen an occultation of the 1¢@ of the crab, ef 
the fourth magnitude, by the Moon. The immerfon will be-at-44 minutes paft-nine, ap- 
parent time, or at 272 minutes paft eight, clock time; and the emerfion at 144 minutes 
paft nine, apparent time, or at 274 minutes paft nine, clock-time. ‘The difappearance of 
the ftar will be at that part of the confines of the Moon’s unenlightened difk which is 5 
minutes to the north of her centre 3 and its re-appearance at the bright edve of thedMoon, 
7 minutes to the north of her centre. On the 9th, at 30m. 54s. pait dix, eyening, will hap- 
pen an emerfion of Jupiter’s firft fatellite, the-only one that wall be vilitle to Great Britain 
before the 13th of next O&tober... A vifible immerfion of this-fatellite will not take place 
before the 2nd of next July. There will not be a vifible immerfion of the fecond fatellite 
before the 23d of next Jume; ner a vifible emerfion before the 15th of next October’ A 
vifible immerfion of the third fateHite will not happen before the 74th of next June; nora 
vilible emerfion before the 27th of next July.. The firft. vilible immerfon and emerfion of 
the fourth fateilite will not take place before the night of Feb. 28,1812. Mercury may be 
feen, if the weather be favourable, about twenty days; that is, ten days betore and ten 
days after the time of his greateit elongation which takes place on the i7th. On account 
of this planet being in his perihelion on the day of his greateft elongation, the angle that 
he then makes with the San will be only 18° @, which is ulmoft the leaf poffible. Note 
withftanding this circumftance, he will fet that day not lefs than 1h.40m. after the Sun, 
becaufe that part of the Zodiac that he will then he in bears fo great an angle with the ho- 
tigen. He fete pn the 7th 1h. i6m. on the igth ih. 47m. and ‘vn the 27th 1h, Im.
