While we have felt it our duty to write the last paragraph, we cheerfully record our admiration of Sir Robert Peel's great talents, of his moral integrity, of his very exemplary private life, and, we believe, of his firm attachment to his country and its institutions. He is another memorable instance of what the children of democracy may become in England, with adequate talents and exertions. Sir R. Peel owed much to his wealth, to his associates, and to his early opinions. But far beyond the factitious influences derivable from such sources, he had great elements in himself. When his heart and mind received free permission from his policy to display themselves, they were of the highest order. Such a man is not easily made: of his loss we are only at present very imperfectly able to appreciate the consequences, one of which, we fear will be a mischievous re-formation of the Protectionist party, and, if we read the auspices aright, his death will not improve the Ministerial Whigs.
The motion on Wednesday night, in the House of Commons, not to proceed with public business that evening, in honor of the memory of Sir R. Peel, was as becoming to the House itself as it was to its mover, Mr. Hume. It is a poor recompense to a bereaved family, we are aware; but it is such a tribute as has not always been granted to even greater men, and to some of the blood royal. In due time the public feeling will doubtless imbody itself in more tangible and permanent forms; and when that occurs, it will not be the least of the monumental honors of the deceased, that the gratitude of the widow, the orphan, the neglected genius, and suffering worth, will lead many to shed their tears on the bronze or marble effigies of him whose like England will not easily see again.

SPONGES.
About three centuries and a half before the Christian era, the question, Are sponges animal or vegetable? was proposed by Aristotle, who, unable himself to solve the difficulty, was contented, in the true spirit of a lover of nature, with carefully recording the results of his accurate observations, and advancing his opinion rather in the form of an inquiry than of an allegation. Upward of two thousand years rolled away ere this question was satisfactorily answered. Nay, we believe that the vegetable theory has, even at the present time, its advocates; while some are still disposed to consider that the sponge is at one period of its existence a vegetable, and at another an animal.
To any one who hesitates to acknowledge that the sponge is endowed with animal life—confessedly in its lowest form, yet with a most exquisite adaptation to its destiny—we would offer the spectacle of a living sponge in a portion of its native element. We would let him gaze on the animated fountain, which is perpetually sucking the water into its substance through its countless pores, and after assimilating such particles of it as are essential to its existence, ceaselessly expelling it, at more distant intervals, through the larger channels which may be observed on its outer surface. We would point out innumerable gemmules of gelatinous matter, which at certain seasons of the year may be seen spouting "from all parts of the living film which invests the horny skeleton;"[24] until, at length, escaping from the nursery in which they grew, they are carried off to the wide sea by means of the force of the currents issuing from the sponge, though not left to perish at the mercy of the waves. For he will find that the young animal or egg is covered with numberless minute hairs or cilia, each one of which is endowed with a distinct and innate power of vibration; so that by means of thousands of almost invisible oars, the young sponge "shoots like a microscopic meteor through the sea," until it arrives at some rock or other place properly adapted for its future growth; then it settles calmly and contentedly down, and gradually losing its locomotive power, begins to spread on its base; and builds up, within its living substance, a horny framework, such as we have already seen in its parent.
The above-named currents may be more distinctly seen by powdering the surface of the water with chalk or any similar substance; and Professor Grant mentions, that by placing pieces of cork or dry paper over the apertures, he could see them moving "by the force of the currents at the distance of ten feet from the table on which the specimen rested."
Dr. Peysonell, who paid great attention to the structure of the sponge, brought proofs of its animal vitality before the Royal Society in the years 1752—57. And Mr. Ellis, five years afterward, by his dissections, set the question quite at rest; though he fell into the error of believing that the frame of the sponge was the outer case of worms or polypes. Later examination, however, has shown that the frame or sponge, commonly so called, is an internal skeleton, while the vital power is simply composed of a slimy film which coats over every fibre, and which, inert as it appears, possesses the power of secreting the particles essential to its growth.
It has been affirmed, that the sponge is observed to contract or shrink when torn from the rooks; but there is satisfactory evidence to prove that neither this nor any degree of laceration has a sensible effect on this nerveless though vital mass.
