Snowdon, in England, by raising the land, the elevation of. the region 
must be 7,000 or 8,000 feet above the present level, or to a height of 
11,000 feet, as this would be required to-carry it 1,000 feet above the 
snow level, and the glaciers might in such a ease be expected to de- 
produce a cold temperature at Snowdon, having the probable mean 
of 39° or 40° F., making the line of 32° F. at a height of 2,200 feet, 
acold current strike on the land, this would diminish the temperature 
further ; and should it make a difference of but 8° or 4°, it would bring 
the snow limit down 1,000 or 13200 feet lower, which would account 
for glaciers reaching the sea, even on the lower mountains of Ireland. 
The same conditions would make the’ show-line on the Alps 5,000 or 
6,000 feet above the sea. The present climate of Fuegia illustrates 
well the theory, ‘

New Planet, (Astr. Jour., No. 45.)—Another planet was discovered 
on the night of June 24, 1852, by Mr. J. R. Hind, of London. At ap- 
peared like a star of the ninth magnitude, with a steady yellowish light. 
Its apparent place June 24, 13" 13%! 53° Gr. m. t. was R. A. 18h 12m

1, Remarks on the Climate of San Francisco.— The Sea-Breeze ; by 
Dr. H, Gipzons, (from the California Christian Advocate of April 1, 
1852.)—The tables contained‘in my last number,* exhibit the great ex- 
anuary and December, 
and that the latter month varies in this respect, being sometimes on 
-Thave already stated that the westerly winds increase both in fre- 
quency and in force from February to July, and then begin to fall off 
very gradually. The precise relation of sea to land winds, in each 
Month, as to frequency, is shown by computing their per-centage of the 
whole number of observations. ‘The result for the year 1851,is.as follows:
