The Descent of Man

sed races at once gives to an aboriginal race an
immunity from the evil consequences of changed
conditions. Thus the crossed offspring
from the Tahitians and English, when settled in
Pitcairn Island, increased so rapidly that the
island was soon overstocked; and in June 1856
they were removed to Norfolk Island. They
then consisted of 60 married persons and 134
children, making a total of 194. Here they likewise
increased so rapidly, that although sixteen
of them returned to Pitcairn Island in 1859, they
numbered in January 1868, 300 souls; the males
and females being in exactly equal numbers.
What a contrast does this case present with that
of the Tasmanians; the Norfolk Islanders IN-
CREASED in only twelve and a half years from
194 to 300; whereas the Tasmanians DECREA-
SED during fifteen years from 120 to 46, of
which latter number only ten were children.
