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: -
Summer Winter Mean of Summer
Latitude Temp. Temp. and Winter
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
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 9.5 degs. less hot in
summer, than Dublin.
