Several strange opinions have been entertained respecting these beautiful bodies arising from the remarkable peculiarities of their motions and physical phenomena. Some bave supposed that the immense atmospheres of two of them are derived from the “ lost comet of 1770.” Others have considered them as the fragments of an exploded planet, and that meteorolites, which occasionally fall to the earth, are some of the smaller masses. On this subject Mr. E. J. Lance has suggested that, as the component parts of meteorolites are similar to terrestrial substances, there does not seem any necessity for tracing them to so distant a source as a planet that once moved between Mars and Jupiter. A chemical process, the electric and galvanic fluid, will dissipate iron, nickel, sulphur, &c., which are the component parts of these aerial masses, and that as these, when thus acted upon, either naturally or artificially, lose a portion of their weight, it is probable that particles are taken up by the atmosphere, and, being re-combined by electric agency, fall to the earth at the instant of their re-combination in the form of meteorolites.
But these small planets are neither the wreck of a
ruined world, nor are they wrapped in the newly acquired train of a comet wandering from its course. In the whole of creation, wherever the power of the Divine Being is evinced, there is also displayed harmony, and an arrangement for the general preservation; a beautiful connexion may be traced, uniting bodies apparently opposite in their natures, gliding through the various links which ascends from the minute to the stupendous - from the grain of sand, that fetters the proud ocean, to the rolling world, and all the vast orbs that move through immensity.

FORM OF SATURN'S RING. The sun will be in the plane of the Ring of Saturn, at lh. after noon of the 1st day; the northern side of the ring visible, which is indicated by the sign + being prefixed to the semi-conjugate axis. December 1st.-Semi-transverse axis — 39”.56

SPHERE OF THE FIXED STARS.
Telescopic Objects. Castor. The stars are both white, and of nearly equal magnitude; may be distinctly seen with a telescopic power of 100. No. 1, in the engraving of double stars.
Rigel, the double star in the foot of Orion, is visible with any power between 80 and 130, the small star is of a reddish tint. No. 2.
The triple star in the right fore foot of Monoceros, requires a power of 120; it has been considered one of the most beautiful objects in the heavens. No. 3.
n in Corona Borealis, is an exceedingly delicate double star, and can only be seen under very favourable circumstances; it requires not only a very perfect, but also a very large telescope. No. 4.
Polar Star. The two stars are exceedingly unequal in size; this double star may be seen with any power higher than 40. No. 5.
ɛ in Boötes, is seldom seen distinctly defined with a power below 250 ; the smaller of the two stars is of a blue colour, the intensity of which increases in proportion to the proximity to the horizon. No. 6.
& in Lyra, with the low telescopic power of 5, resembles Castor, when magnified with 450. With the power of 120, this beautiful double-double or quintuple star, may be seen as in the engraving of double stars. *
When it is proposed to view any of the minute double stars, such as n in Corona Borealis, let the telescope be some time before directed to Castor, or ε in Lyra ; these
