1. Btm'g's Observations on the Eclipse of the 1th Sept. 18^0. 
—Being desirous of seeing an annular eclipse of the sun, the 
Chevalier Burg went for this purpose to Klagenfurth in Carin- 
thia. The cloudiness of the weather prevented him from seeing 
the beginning and end of the eclipse, and also the first interior 
contact ; but he observed the evanescence of the ring to take 
{)lace about 3^ 16' 57".6 of true time, or 3^ 14' 46".4 of mean 
time. The latitude of the place of observation he found to be 
46° 37' 37'''' ; and the longitude, by various observations, was 
47' 51".S East of Paris. By trigonometrical operations, the 
longitude of the Cathedral of Klagenfurth was 47' 5S".8 ; and 
its latitude 46° 37' 37". The distance of the place of observa- 
tion west of the Cathedral was 0".5. By comparing the obser- 
vations made at Klagenfurth with those at other places, M.^Burg 
concludes that they cannot be made to agree, by adopting the 
diameters of the sun and moon, as given in Delambre’s tables of 
the sun, and his own tables of the moon. He found, that the 
sum of the semidiameters must be diminished by 6".2, and their 
difference by 1".6 ; the semidiameter of the sun by 3".9, and 
that of the moon by 2''.3. M. Burg had deduced an analogous 
result respecting the semidiameter of the moon, from observations 
of the immersion of stars of the first and second magnitude be- 
hind her limb ; but as his researches respecting the moon’s nodes 
did not require any such diminution in the semidiameters of the 
two luminaries, he is disposed to think that the above results 
*may be owing to irradiation and inflexion. — Astronomische

Astronomical Journal. — The first number of a nev/ astro-

ingenious and active astronomer, M. Schumacher, Professor of 
Astronomy at Copenhagen, has just been published at Altona. 
Each number is to consist of a single quarto sheet, to be publish-
