If I have caused thee pain,
That thou didst sometimes clog my course,
Well hast thou in my service wrought :
A quiet bed
Yet shall we meet. To soothe thy pain,
Then shalt thou glorious rise and fair,
And I, with hovering wing elate,
Co-heir of immortality.”
L. H. S.
BY JACOB BRYANT.
The stormy March has come at last,
With wind, and cloud, and changing skies ;
That through the snowy valley flies.
Ah, passing few are they who speak,
Wild stormy month! in praise of thee;
Thou art a welcome month to me:
For thou to northern lands again
The gay and glorious sun dost bring;
And wear'st the gentle name of Spring.
And in thy reign of blast and storm
Smiles many a long bright sunny day,
And heaven puts on the bloom of May.
Then sing aloud the gushing rills,
And the full springs from frost set free,
Are just set out to meet the sea.
Of wintry storms the sullen threat ;
A look of kindly promise yet.
And that soft time of sunny showers,
Seems of a brighter world than ours.
THE SPOTTED OPOSSUM.
(With an Engraving.) The Opossuin is native of New South Wales. Of this animal there are various species. · The spotted Opossum, of which a view is given in the annexed engraving, is in length from the nose to the extremity of the tail about twenty-five inches, of which the tail itself takes up about nine or ten. The general colour of the animal is black, inclining to brown beneath; the neck and body are spotted with irregular roundish patches of white; the ears are pretty large, and stand erect; the visage is pointed, the muzzle furnished with long slender hairs; the fore as well as hind legs, from the knees downward, are almost naked, and ash-coloured; on the fore-feet are five claws, and on the hind four, and a thumb without a claw: the tail, for about an inch and a half from the root, is covered with hairs of the same length as those on the body;
from thence to the end with long ones, not unlike that of a squirrel. The specimen from which this account is taken is a female, and has six teats placed in a circle with in the pouch.
Another animal of the Opossum kind, but of a different species, is described in the following manner. The countenance much resembles that of a fox; but its manners approach more nearly to those of a squirrel. When disposed to sleep, or to remain inactive, it coils itself up into a round form; but when eating, or on the watch for any purpose,
sits up, throwing its tail behind it. In this posture it uses its fore-feet to hold any thing, and to feed itself. When irritated, it sits still more ereet on the hind legs, or throws itself upon its back, making a loud and harsh noise. It feeds only on vegetable substances.
This specimen is a male. The fur is long, but close and thick; of a mixed brown or greyish colour on the back ; under the belly and neck, of a yellowish white. Its length is about eighteen inches, exclusive of the tail, which is twelve inches long, and prehensile. The face is three inches in length, broad above, and pointed at the muzzle, which is furnished with long whiskers. The eyes are large, but not fierce. On the fore-feet are five claws; on the hind feet, three and a thumb. There are six cutting teeth in the front of the upper jaw; and two in the lower; the upper projecting beyond the under. The affinity of so many quadrupeds to the Opossum kind, in New South Wales, in the circumstance of the pouch in which the female receives and suckles her young, opens to the naturalist a field of curious and interesting investigation.-Governor Phillips's Voyage to Botany-Bay.
(Continued from page 82.) Q. If the simple substances are so few, how then are the innumerable bodies around us formed ?
A. By the different combinations of simple substances. Q. Give an example or two.
A. The combination of oxygen and hydrogen forms water. The union of carbon and iron produces steel; and calcium combined with oxygen forms lime.
Q. Give some further illustration of the difference between simple and compound bodies.
A. The oxygen, hydrogen, carbon, iron, and calcium have not been decomposed, nor rendered more simple by analytical examination.
Q. And will not the same observation apply to water,
A. No; these may be decomposed and rendered more simple. The first may be reduced to oxygen and hydrogen; the second to carbon and iron; the third to calcium and oxygen. Separate, they are simple substances; combined, they are compound bodies.
Q. Are simple substances supposed to have ultimate atoms which will not admit of further division ?
A. This is supposed to be the case. Every particle of lime, however small, must have an atom of oxygen and an atom of calcium, and be divisible: but it is assumed that there are ultimate atoms of oxygen and of calcium which will not admit of further division.
Q. What causes these simple substances to combine, and form the bodies by which we are surrounded ?
A. Some agent, or special operation of the Divine Being, (“for where his power is, there is He,") which we know by the name of attraction.
Q. Are there any various and distinct terms, by which the operation of this force is described ?
A. Yes: attraction is said to operate at sensible and at insensible distances ; on masses, and on atoms of matter.
Q. Restricting at present our observations to attraction as it operates at insensible distances, and on atoms; how is this known?
A. If on atoms of the same nature, it is said to be the attraction of aggregation; if on atoms dissimilar in their nature, it is said to be the attraction of composition, or chemical affinity
Q. Can you illustrate what you mean by some example?
A. Yes; I take this bar of iron: it is formed of atoms of the same nature, and the union of these particles is an example of the attraction of aggregation. But on close 'examination, I find a spot thereon, which is commonly denominated rust: this is an oxide of iron; or a combination of one atom or more of oxygen, with a portion of the iron : these elements are different in their nature, and furnish an example of the attraction of composition, or chemical affinity.
