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. Those of a scrofulous diathesis need not
consider it hazardous, as experience does not show that in such there is
any greater susceptibility to local or constitutional disorders, or that
when these are present, there is greater difficulty in their removal.

To those threatened with consumption, the island may be supposed to
offer some advantages in the equability of the temperature, and the
comparative quiescence of the lungs from reduced necessity for
respiratory effort. Besides, the choice of climates presented by Ceylon
enables a patient, by the easy change of residence to a different
altitude and temperature, avoiding the heats of one period and the dry
winds of another, to check to a great extent the predisposing causes
likely to lead to the development of tubercle. This, with attention to
clothing and systematic exercise as preventives of active disease, may
serve to restrain the further progress though it fail to eradicate the
tendency to phthibis. But when already the formation of tubercle has
taken place to any considerable extent, and is accompanied by softening,
the morbid condition is not unlikely to advance with alarming celerity;
and the only compensating circumstance is the diminution of apparent
suffering, ascribable to general languor, and the absence of the
bronchial irritation occasioned by cold humid air.

_Dyspepsia_.--Habitual dyspeptics, and those affected by hepatic
obstructions, had better avoid a lengthened sojourn in Ceylon; but the
tortures of rheumatism and gout, if they be not reduced, are certainly
postponed for longer intervals than those conceded to the same sufferers
in England. Gout, owing to the great cutaneous excretion, in most
