the organs of touch may be so refined as to show a diseased sensibility;
the ear may become so exquisitely sensitive as to be more susceptible to
the uneasiness produced by discords than to the pleasures of harmony. In
the nations which have been long civilised the defects are generally
those dependent on excess of sensibility--defects which are cured in the
next generation by the strength and power belonging to a ruder tribe. In
looking back upon the vision of ancient history, you will find that there
never has been an instance of a migration to any extent of any race but
the Caucasian, and they have usually passed from the North to the South.
The negro race has always been driven before these conquerors of the
world; and the red men, the aborigines of America, are constantly
diminishing in number, and it is probable that in a few centuries more
their pure blood will be entirely extinct. In the population of the
world, the great object is evidently to produce organised frames most
capable of the happy and intellectual enjoyment of life--to raise man
above the mere animal state. To perpetuate the advantages of
civilisation, the races most capable of these advantages are preserved
and extended, and no considerable improvement made by an individual is
ever lost to society. You see living forms perpetuated in the series of
ages, and apparently the quantity of life increased. In comparing the
population of the globe as it now is with what it was centuries ago, you
would find it considerably greater; and if the quantity of life is
increased, the quantity of happiness, particularly that resulting from
the exercise of intellectual power, is increased in a still higher ratio.
Now, you will say, 'Is mind generated, is spiritual power created; or are
those results dependent upon the organisation of matter, upon new
perfections given to the machinery upon which thought and motion depend?'
I proclaim to you," said the Genius, raising his voice from its low and
sweet tone to one of ineffable majesty, "neither of these opinions is
true. Listen, whilst I reveal to you the mysteries of spiritual natures,
