questions, and especially their relation to European residents, has so often been made
the object of detailed reports.1

What, I |,hink, I must especially allude to, is the circumstance that a temperature
beyond a certain degree, though it may suit other races very well, is a limit to
permanent settlement and colonization for Europeans; such was, I can say, more or
less modified, the answer of by far the greater part of the gentlemen consulted,
as well as my own and my brother's reply,2 when the various opinions were asked
before the Parliamentary Committee. Railways may have an unexpected and considerable
importance by their facilitating to settlers a change of climate more easily and more
rapidly, when the health begins to become affected. Drainage, beneficial as it may be
locally, always remains too much limited to become of general importance.

As a temporary refuge for those who cannot reach home, Sanitaria in mountainous
regions and on islands were established.

In Hill-Stations the elevation is one of the most effective causes for appreciably
cooling the temperature, if it reaches a sufficient height; but below this, unless of the
form of isolated mountains and ridges, its influence is felt but little, particularly in
the hot season. In Maissur, in the Dekhan, we have numerous instances of the heat
becoming even more intensive on these plateaux than at the very level of the sea,
where it is modified by a not too great distance from the ocean. I have taken care,
however, to collect all the most recent data3 in reference to the mountainous Sanitaria
also to the south of the Himalaya, where their isolated position makes them more
important than climate alone would.

The decrease of atmospheric pressure is not yet considerable enough in any of
Indian Sanitaria to exercise, as in the Himalaya and in Tibet it does, a very appreciable
influence, except on delicate constitutions.

Marine Sanitaria on islands, as the maps of isothermal lines will show, may be
expected to differ but little from the climate of the Indian coasts; places can be

1 As the most recent general data I quote those contained in the Parliamentary publication " Reports from the
select Committee on Colonization and Settlement," 1858, in addition to those publications of the "Commission on
the Sanitary State of the Army in India" to which I have already repeatedly had occasion to refer.

Also the "Medical Topographies," &c, quoted in the tables of literature, are rich in details about the sanitary
conditions of various provinces.

3 Many of them only reached me at the end of last summer, and therefore could not be included in my
"Numerical Elements of the Meteorology of India," in the Transactions of the Royal Society.
