machine for giving the point or place of emerson. Where shall I 
find a description of it? On p. 7, it is erroneously set down that 
there will be a total eclipse of the moon on the 26th of December, 
visible at Paris; and no notice is taken of an eclipse of the sun, 
Jan. 10; another, Dec. 30; nor of one of the moon, Dec. 15 ; all 
invisible here. On p. 5, the Julian period is stated as 6530; in 
the English ephemeris, at 6528: and the apparent.obliquity of the 
ecliptic, Oct. 1, according to Delambre’s new tables, = 23° 27%

1X. Weather in Iceland during 1814, 
(To Dr, Thomson.) 
Sik, 
Asit may not perhaps be uninteresting to some of your readers to 
know the general state of the weather in Iceland during, the past 
year, I beg leave to subjoin an extract of a letter on that subject, 
which I lately received from Mr. Magnus Stephenson, Chief Justice 
in that island, dated Rechiavig, July 26, 1815. 
Iam, Sir, respectfully, your most obedient servant,

<A remarkably fine summer (1814) was succeeded by a very 
stormy autumn, attended with much rain and raw weather. From 
the beginning of October to the end of -December followed much 
snow and sharp frost, the stormy state;of the weather still conti- 
nuing. From thence to the middle of March succeeded very fine 
mild weather, without frost; yet often so windy that the fishing 
could not begin during all that period. Afterwards the weather 
became calm and agreeable, which cotitinued 3 and we have scarcely 
had apy frost in 1815 here in the south and the eastern parts of the 
islands but in the northern \part, the winter being milder from 
September to January, afterwards changed to, very stormy, with 
snow. It continued ,thus, until far in the spring; the consequence 
of which bas been a greatJoss of sheep in the north country, where 
the grass came late, and was very scarce every where: besides which 
it was in some parishes,eaten quite away by a caterpillar last spring, 
which was exceedingly cold, although no drift ice has appeared this 
year on the northern coast,”
