The pale and sallow complexion of ladies and children born in India, is ascribable in a certain degree to the same process by which vegetables are blanched under shades which exclude the light:--they are reared in apartments too carefully kept dark.] _Paleness_ .-- At the same time it must be observed, that the pallid complexion peculiar to old residents, is not alone ascribable to an organic change in the skin from its being the medium of perpetual exudation, but in part to a deficiency of red globules in the blood, and mainly to a reduced vigour in the whole muscular apparatus, including the action of the heart, which imperfectly compensates by increased rapidity for diminution of power.

It is remarkable how suddenly this sallowness disappears, and is succeeded by the warm tints of health, after a visit of a very few days to the plains of Neuera-ellia, or the picturesque coffee plantations in the hills that surround it.
_Ladies_ .-- Ladies, from their more regular and moderate habits, and their avoidance of exposure, might be expected to withstand the climate better than men; and to a certain extent the anticipation appears to be correct, but it by no means justifies the assumption of general immunity.

Though less obnoxious to specific disease, debility and delicacy are the frequent results of habitual seclusion and avoidance of the solar light.

These, added to more obvious causes of occasional illness, suggest the necessity of vigorous exertion and regular exercise as indispensable protectives.
If suitably clothed, and not injudiciously fed, children may remain in the island till eight or ten years of age, when anxiety is excited by the attenuation of the frame and the apparent absence of strength in proportion to development.

These symptoms, the result of relaxed tone and defective nutrition, are to be remedied by change of climate either to the more lofty ranges of the mountains, or, more providently, to Europe.
_Effects on Europeans already Diseased_ .-- To persons already suffering from disease, the experiment of a residence in Ceylon is one of questionable propriety.
