services of science to humanity; he dwelt upon its dignity and nobility as a pursuit, upon its value as a moral and educational force. The small, spare youth, with his earnestness, his eloquence, his unaffected manner, the play of his mobile features, his speaking eyes--“eyes which,” as one of his fair auditors was heard to remark, “were made for something besides poring over crucibles”--held his hearers spellbound as he declaimed such sentences as these:-- “Individuals influenced by interested motives or false views may check for a time the progress of knowledge;--moral causes may produce a momentary slumber of the public spirit;--the adoption of wild and dangerous theories, by ambitious or deluded men, may throw a temporary opprobrium on literature; but the influence of true philosophy will never be despised; the germs of improvement are sown in minds, even where they are not perceived; and sooner or later the springtime of their growth must arrive. In reasoning concerning the future hopes of the human species, we may look forward with confidence to a state of society, in which the different orders and classes of men will contribute more effectually to the support of each other than they have hitherto done. This state, indeed, seems to be approaching fast; for, in consequence of the multiplication of the means of instruction the man of science and the manufacturer are daily becoming more assimilated to each other. The artist, who formerly affected to despise scientific principles, because he was incapable of perceiving the advantages of them, is now so far enlightened as to favour the adoption of new processes in his art, whenever they are evidently connected with the diminution of labour; and the increase of projectors, even to too great an extent, demonstrates the enthusiasm of the public mind in its search after improvement.... “The unequal division of property and of labour, the differences of rank and condition amongst mankind, are the sources of power in civilised life--its moving causes, and even its very soul. In considering and hoping that the human species is capable of becoming more enlightened and more happy, we can only expect that the different parts of the great whole of society should be intimately united together, by means of knowledge and the useful arts; that they should act as the children of one great parent, with one determinate end, so that no power may be rendered useless--no exertions thrown away.
