deposits, have been conveyed thither either on icebergs or
frozen in coast-ice. The connection between the transportal
of boulders and the presence of ice in some form, is strikingly
shown by their geographical distribution over the earth.
In South America they are not found further than 48 degs. of
latitude, measured from the southern pole; in North America
it appears that the limit of their transportal extends to
53.5 degs. from the northern pole; but in Europe to not more
than 40 degs. of latitude, measured from the same point. On the
other hand, in the intertropical parts of America, Asia, and
