The following discussion on the climate of the southern parts of
the continent with relation to its productions, on the snow-line,
on the extraordinarily low descent of the glaciers, and on the zone
of perpetual congelation in the antarctic islands, may be passed
over by any one not interested in these curious subjects, or the
final recapitulation alone may be read. I shall, however, here give
only an abstract, and must refer for details to the Thirteenth
Chapter and the Appendix of the former edition of this work.
ON THE CLIMATE AND PRODUCTIONS OF TIERRA DEL FUEGO AND OF THE
SOUTH-WEST COAST.
The following table gives the mean temperature of Tierra del
Fuego, the Falkland Islands, and, for comparison, that of
Dublin:--
Latitude Summer Winter Mean of Summer
degrees ' Temp. Temp. and Winter
deg. F. deg. F. deg. F.
---------------------------------------------------------------
Tierra del Fuego 53 38 S. 50 33.08 41.54
Falkland Islands 51 38 S. 51 -- --
Dublin 53 21 N. 59.54 39.2 49.37
Hence we see that the central part of Tierra del Fuego is colder in
winter, and no less than 9 1/2 degrees less hot in summer, than
Dublin.
