The quantity of rain fallen fince the Jaft Report is equal to 4.470 inches in depth. 
During the Jaft month the variations in the denfity of the air have again been but trifling: the 
barometer has for a few hours only been below change, and although the mercury fell rather more 
than three tenths of an inch between the 18th and igth, yet by the fame hour on the 2oth it 
had refumed its former place. Its average height, being 29.843, fell fomething fhort of what it 
had been the two preceding months. 
The public attention has, during the laft week, been arrefted by chariges inthe temperature of the 
atmofphere, more rémarkable probably than was ever remembered at this feafon of the year by the 
oldeft man alive... During three fucceffive days there’ were repeated’ falls of hail and fnow, and 
though, in the neighbourhood of the metropelis, they were but flight, yet at a farther diftance 
in the country, the ground was frequently completely covered; the froit on thefe mornings was. . 
ungommonly fevere; ice was feen more than a quarter of an inch thick; after fun rife on the 
16th the meréury was at 29°, and, at a few minutes after four on the 1$th,-it .was actually. at 
25°, or feven degrees below the freezing point. This was a degreé of cold which we apprehend ie 
to have been-unparalleled in this country on the 19th of May... Qn the fame. day.in the year 
1794,” which the writer of this-article well remembers, peafe wer® fold in London at eighteen 
pence per peck. A ftrange difference between the feafons of that year and the prefent. 
Dr. Herfchel, in a paper of the Philofophical: Tranfa€tions, and which has been noticed in 
another part of this number of the Monthly Magazine, has attempted. to eitablifh a new theory 
refpecting the nature of the:fun, in which he-has pointed out certain fymptomatic difpofitions of _ 
the fun-for emitting light and heat: Unfortunately for the dodirine of ‘this truly great aftrono- 
mer, the prefent feafon ought to have been highly favourable to vegetation and agriculttrak fer-., 
tility; while, therefore,. we-are willing to treat his opinions witha refpect and deference due ta - 
his great talents, we Cannot, without more appofite facts, admit that the difference of thé feafons

-in.this coyntry.is owing to a more-or lefs copicus emffion of the folar beams. © 9.9 7 
., Notwithftanding the.keat of the weather the laft four days, the average height of the thérmio- 
meter, for the whole month. is only 50:78, nearly a degree lefs than the mean height of the lait 
month. _ Y . SUS Gee Utd RS Ne 
The quantity of rain fallen, though very fmall, is nearly double that mentioned in the laft Re.« 
port; ftill, however, the earth gapes for a freth fupply, and unleds fome fhowers fall fpeedily,:. 
we may dread the return of fcarcity. - *

Further Account of the laft new Planet, Pallas. 
Dr. Olbers, who difcovered it.on the 28th of March, after obferving it for five weeks, 
was fully perfuaded‘of its being a trué planet. Dr. Gaufs has determined the elements of its 
orbit, as near as could be done. from {fo fmall a part’of ‘it. ‘Its excentricity is a little greater 
than that of Mercury 3 the inclination 33° 39’; its mean diftance a litgle lefs than that.

Ceres;-and its periodic time four years and ‘five months, or.two months lefsthaa that of Ceres. 
But the-moft remarkable circumftance. cOnCéerning it is, that it crofies.the orbit of Ceres, 
approaching the fun nearer in its perihelium, and receding further from him in his aphelium, 
shan Ceres does. Dr. Herfchel has made fome curious obfervations of the apparent diameter&. 
. both of “Pallas and Ceres, from‘ which he infers the real diameter ot Pallas tobe 95. miles, 
and-that of Ceres 162 miles. He confidets them of a different fpecies fiom. the known planets, 
¥n their fmallnefs and motions they refemble comets; but-in the clearne{s of their light they 
refemble the other planets. als ng a Meee Se . feb iene
