Astronomical Occurrences

In MAY 1829.

Look forth, where those eternal planets roll
Harmonious, through the pathless heaven, and trace
A power that guides and animates the whole;
Mark with what prodigality of grace
Majestic nature clothes her varied face,
And say what hand adorned that rolling ball-
What voice was His, that, from the depths of space,

Bade worlds awake at his creating call,
And breathed the breath of life and vigour through them all?

Anon.

SOLAR PHENOMENA. The Sun enters Gemini at 31 m. after 9 in the morning of the 21st of this month: he also rises and sets, during the same period, as in the following

8 The time of rising or setting on any of the intermediate days may easily be found by proportion. For instance-let his time of rising on the 8th of the month be required: the difference between the times for the 6th and the 11th is 9m., and the interval five days; and therefore 5 : 2 :: 9:33 m., which, taken from 29, gives 25 m. past 4 for the time sought.

Equation of Time. When it is required to reduce apparent to mean time, subtract the equation of time from that given by a good sun-dial, and the remainder will be the time required.

Other Phenomena.. Mercury and Venus will be in conjunction with each other on the 4th of this month. Mercury will be in his superior conjunction at 45 m. after 1 in the morning of the 8th. Georgium Sidus will be stationary on the 11th; and Venus will be in her superior conjunction at a quarter past 8 in the evening of the 20th.

Curious Phenomenon in Saturn's Ring. On the 21st December, 1827, M. Schwabe observed that the dark space between the body of Saturn and his ring appeared larger on the eastern side of the planet than on the western side. Mr. Herschel and others were also of opinion that the eastern space was the largest; but, from his observations, and those of Mr. South's, it appears that there is no difference. Thus

.35.532

1st set of 35 Observations. Eastern space...3 .472 } 2d set of 20 Observations Of the last set ten were made by Mr. Herschel, and gave,

Western space

.35.612

Eastern space....3 .442; and ten by Mr. South, which gave,

Western space ...3".331
Eastern space....3.502.

Western space

Hence it follows, that the phenomenon is an optical deception. Professor Struve, however, is decidedly of opinion, from observations with his splendid achromatic telescope, that Saturn is not in the centre of his ring. From a mean of 15 measurements he makes the apparent distance on the east side 11".272, and on the west side 11".390, making a difference of 0”.215. The probable error of his mean measurements he regards as 0".024, the ninth part of the difference above found.-Edin. Jour. of Science, Oct. 1828.

To a STAR.

[By Barry Cornwall.]
Now, from thy skiey road look down upon me,
Hesper, star of my sad nativity!
With no upholy thought I dare to court
Thy lustrous eye upon me; and as to one
Known in some happier hours I bid thee hail,
After my many wanderings. I have seen
Thy burning glance on bare and peopled lands,
Civil and savage,-on the parched plains
Of India, and the sands of Palestine,
On tropic waters, and on iced shores,
And on the far and solitary seas
O'the south. l’ve roamed this circular world, and thou
Hast followed me like fate, yet never looked
Before with such kind aspect. Thou art now
Shining above my home, and hallowing
The sweet haunt of my infancy. - I come,
After my toils and dangers, to seek rest,
And love, and welcoming eyes, and gentle hearts.
Oh, thou bright Star! be now my messenger,
And from thy cloudy palace (for the clouds
Are rolling round about tbee) glance upon
My mother's house with thy expressive eye,
And to the dear inhabitants, gentle Star,
Dart smiling tidings, that the boy they loved
Is come indeed. Shipwrecked, and lost for years,
He lives, redeemed from his watery grave,-,
Lives, and will be a blessing. And on the cheek
Of one supremely soft and beautiful,
Light like the cheerful ray of a summer morning;
So may my own Olympia know that still
Juan, the wanderer, lives.

The Naturalist's Diary

For MAY 1829.
How heavenly o'er my frame steals the life-breath
Of beautiful Spring! who, with her amorous gales
Kissing the violets, each stray sweet exhales
Of May-thorn, and the wild flower on the heath.
I love thee, virgin daughter of the year!
Yet ah! not cups,--died like the dawn, impart
Their elves' dew.nectar to a fainting heart!
Ye birds! whose liquid warblings far and near
Make music to the green turf-board of swains;
To me, your light lays tell of April joy,-
Of pleasures-idle as a long-loved toy;
And while my heart in unison complains,

Tears like of balm-tree flow in trickling wave,
And white forms strew with flowers a maid's untimely grave!

New Monthly Magazine. The weather during May and June is usually the most pleasant of the whole year; the air is pecu. liarly soft and refreshing, being scented with the balmy fragrance of innumerable flowers and opening buds. Almost every part of the vegetable creation is in vigorous growth, and holding forth the pleasing hope of future perfection. The ear is ever saluted by the concert of the groves, and all nature seems to rejoice. The winds are generally variable, in which case there are alternations of showers and sunshine; if steady from any of the northerly points, with a clear sky, frosty air sometimes chills the early hours, and checks the tender shoots.

Easterly Winds and Blights.-A correspondent to that highly attractive periodical, the Magazine of Natural History,' which has furnished so many interesting notices for our Naturalist's Diary, makes the following sensible remarks upon this subject:

April 30, 1828. In conversation with Mr. Gibbs, of Brompton, he stated, that we should certainly have an east wind about this time.' The wind had veered to the east in the morning of this day, but at the time we were speaking it had changed to the north-east.
