some degree for the downward transfer of material by detritus and
alluvial deposits. Hence it may be inferred that, on the whole, the
quantity of solid matter above the ocean-level probably remains nearly
always at the same amount.

It is with this ease and lucidity that Sir John deals with scientific
subjects of the greatest importance,--his genius resembling the
elephant's trunk, which can balance a straw or rend an oak. In private
life he displayed a simplicity of manner in harmony with the general
unassumingness of his character. In his books as in society, in society
as in his books, he was the same,--that is, free from all ostentation,
free from self-pride, free from the arrogance of superior knowledge, and
as ready to unbend himself to a child as to discourse with men of
science.

His career was a tranquil and a prosperous one, and, apart from the
record of his discoveries and his honours, presents nothing of interest.
He was peculiarly happy in his domestic relations; and in the wide
circle of friends attracted by the mingled charm of his intellect and
manners. A devout Christian, a man of generosity and culture, a
philosopher of great breadth of view and infinite patience of
research,--we can place few better or brighter examples before our
English youth than Sir John Herschel.
