THE ISOTHERMAL LINES.

The distribution of temperature over the surface of India, independent of the
local modifications by height, is best shown by the form of its isothermal lines; they
were made the object of the second and third of my physical plates.

In reference to the geographical details, I have limited myself to the principal
river-systems; and to avoid interfering with the distinctness of the isothermal lines,
the names of the stations, as well as the Indian mountain-systems, are left out; for
the means of the year, the Archipelago and countries to the north-east of it are
added, on a smaller scale.

The position of the stations, latitude and longitude being given everywhere, can be
easily found on our route-map, where only the names of some of the smaller stations
had to be left out. I used Meecatok's projection, since the rectangular position of the
lines of latitude and longitude in a chart facilitates the judging of the relative form of
the isothermal lines, and it allows one to employ with it, for comparison, any analogous
extended over a larger surface or representing the neighbouring countries; besides, in the
tropical regions the increase of the dimensions with latitude does not much affect
