I. ARRANGEMENT OF THE METEOROLOGICAL VOLUMES.
A. Temperature, Moisture, Rain. B. Pressure, Wind, Optical Phenomena, Physical and Chemical Experiments.
Climate in general described, together with the details respecting Temperature.
Ail analysis of the physical and chemical qualities of the atmosphere, experiments
and details concerning the heating power of the Sun, and its modification in acting upon
solid or liquid surface—such are the elements from which natural philosophy in most
of the general works on meteorology has started for facilitating the interpretation of
what we observe.
For the observations and materials collected during the travels from 1854-58 I pre-
ferred beginning in this volume with the characteristic of climate and the observations
about temperature, moisture, and rain. For India and the countries to the north of it,
where a region of excessive heat is followed next by that of excessive height, such
materials the better direct the attention to unexpected questions as to the principal
causes. Wind and barometric pressure, optical phenomena, and physical and chemical
experiments, shall be the subjects of the next volume.
Temperature is the active power, the force vive of the meteorological phenomena,
and the tables introduced by a descriptive characteristic of climate can be connected, at
the same time, with the modifications of cultivation and settlement—with the habits
and manners, even the character of the inhabitants. By its influence upon vegetation
temperature is not less important for the types of foreign scenery. Also the great
variety of climates, if we consider the changes from Ceylon up to the Panjab, is in
favour of describing them in the first part of the meteorological researches; it is
