The power of the sun’s rays, another most important point in estimating the effects of exposure, is also considerably less on the Neilgherries than in Great Britain, the maximum and mean being both lower. To sum up, the climate of the Neilgherries is more temper- ate than that of Great Britain, its whole range being also within the limits considered by all authorities, most favours able to the European constitution, The number of days in which rain falls in England, (exclu- sive of snow) greatly exceeds the corresponding number on the hills, their being only 160 fair days in the one case, and 237 in the other; which is important as showing that although the quantity of rain is nearly double, the opportunities for taking exercise are more frequent, in the proportion of 24 to 16, or |-3d. There is also a greater equability of temperature, the daily range being less than in Great Britain, and the extremes * British Medical Almanacs for 1836 and 1838, and Daniel’s Meteorological Essays, + Baikies observations on the Neilgherrics.
