transported by the winds; and a piece of steel, touched by the magnet, points to the mariner his unerring course from the old to the new world; and by the exertions of one man of genius, aided by the resources of chemistry, a power, which by the old philosophers could hardly have been imagined, has been generated and applied to almost all the machinery of active life; the steam-engine performs not only the labour of horses, but of man, by combinations which appear almost possessed of intelligence; waggons are moved by it, constructions made, vessels caused to perform voyages in opposition to wind and tide, and a power placed in human hands which seems almost unlimited.  To these novel and still extending improvements may be added others, whish, though of a secondary kind, yet materially affect the comforts of life, the collecting from fossil materials the elements of combustion, and applying them so as to illuminate, by

a single operation, houses, streets, and even cities.  If you look to the results of chemical arts you will find new substances of the most extraordinary nature applied to various novel purposes; you will find a few experiments in electricity leading to the marvellous result of disarming the thunder-cloud of its terrors, and you will see new instruments created by human ingenuity, possessing the same powers as the electrical organs of living animals.  To whatever part of the vision of modern times you cast your eyes you will find marks of superiority and improvement, and I wish to impress upon you the conviction that the results of intellectual labour or of scientific genius are permanent and incapable of being lost.  Monarchs change their plans, governments their objects, a fleet or an army effect their purpose and then pass away; but a piece of steel toached by the magnet preserves its character for ever, and secures to man the dominion of the trackless ocean.  A new period of society may send armies from the shores of the Baltic to those of the Euxine, and the empire of the followers of Mahomet may be broken in pieces by a northern people, and the dominion of the Britons in Asia may share the fate of that of Tamerlane or Zengiskhan; but the steam-boat which ascends the Delaware or the St. Lawrence will be continued to be used, and will carry the civilisation of an improved people into the deserts of North America and into the wilds of Canada.  In the common history of the world, as compiled by authors in general, almost all the great changes of nations are confounded with changes in their dynasties, and events are usually referred either to sovereigns, chiefs, heroes, or their armies, which do, in fact, originate from entirely different

causes, either of an intellectual or moral nature.  Governments depend far more than is generally supposed upon the opinion of the people and the spirit of the age and nation.  It sometimes happens that a gigantic mind possesses supreme power and rises superior to the age in which he is born, such was Alfred in England and Peter in Russia, but such instances are very rare; and, in general, it is neither amongst sovereigns nor the higher classes of society that the great improvers or benefactors of mankind are to be found.  The works of the most illustrious names were little valued at the times when they were produced, and their authors either despised or neglected; and great, indeed, must have been the pure and abstract pleasure resulting from the exertion of intellectual superiority and the discovery of truth and the bestowing benefits and blessings upon society, which induced men to sacrifice all their common enjoyments and all their privileges as citizens to these exertions.  Anaxagoras, Archimedes, Roger Bacon, Galileo Galilei, in their deaths or their imprisonments, offer instances of this kind, and nothing can be more striking than what appears to have been the ingratitude of men towards their greatest benefactors; but hereafter, when you understand more of the scheme of the universe, you will see the cause and the effect of this, and you will find the whole system governed by principles of immutable justice.  I have said that in the progress of society all great and real improvements are perpetuated; the same corn which four thousand years ago was raised from an improved grass by an inventor worshipped for two thousand years in the ancient world under the name of Ceres, still forms the principal food

of mankind; and the potato, perhaps the greatest benefit that the Old has derived from the New World, is spreading over Europe, and will continue to nourish an extensive population when the name of the race by whom it was first cultivated in South America is forgotten.

“I will now call your attention to some remarkable laws belonging to the history of society, and from the consideration of which you will be able gradually to develop the higher and more exalted principles of being.  There appears nothing more accidental than the sex of an infant, yet take any great city or any province and you will find that the relations of males and females are unalterable.  Again, a part of the pure air of the atmosphere is continually consumed in combustion and respiration; living vegetables emit this principle during their growth; nothing appears more accidental than the proportion of vegetable to animal life on the surface of the earth, yet they are perfectly equivalent, and the balance of the sexes, like the constitution of the atmosphere, depends upon the principles of an unerring intelligence.  You saw in the decline of the Roman empire a people enfeebled by luxury, worn out by excess, overrun by rude warriors; you saw the giants of the North and East mixing with the pigmies of the South and West.  An empire was destroyed, but the seeds of moral and physical improvement in the new race were sown; the new population resulting from the alliances of the men of the North with the women, of the South was more vigorous, more full of physical power, and more capable of intellectual exertion than their apparently ill-suited progenitors; and the moral effects or final causes of the migration of races, the plans of conquest and ambition which have led to

revolutions and changes of kingdoms designed by man for such different objects have been the same in their ultimate results—that of improving by mixture the different families of men.  An Alaric or an Attila, who marches with legions of barbarians for some gross view of plunder or ambition, is an instrument of divine power to effect a purpose of which he is wholly unconscious—he is carrying a strong race to improve a weak one, and giving energy to a debilitated population; and the deserts he makes in his passage will become in another age cultivated fields, and the solitude he produces will be succeeded by a powerful and healthy population.  The results of these events in the moral and political world may be compared to those produced in the vegetable kingdom by the storms and heavy gales so usual at the vernal equinox, the time of the formation of the seed; the pollen or farina of one flower is thrown upon the pistil of another, and the crossing of varieties of plants so essential to the perfection of the vegetable world produced.  In man moral causes and physical ones modify each other; the transmission of hereditary qualities to offspring is distinct in the animal world, and in the case of disposition to disease it is sufficiently obvious in the human being.  But it is likewise a general principle that powers or habits acquired by cultivation are transmitted to the next generation and exalted or perpetuated; the history of particular races of men affords distinct proofs of this.  The Caucasian stock has always preserved its superiority,
