The unhealthiness of the city is chiefly due to want of proper drainage, impure drinkingwater, miasma from the disturbed rubbish heaps, and contaminated dust from the uncleansed roads and streets.
Among elements of unhealthiness is next to be reckoned the proximity of native villages, the inhabitants of which are infected.
The inhabitants, notwithstanding the unhealthiness of their climate, are a strong and athletic race, belying their yellow and sickly appearance.
In an endeavour to stop the slave trade and piracy, the islands were garrisoned (1812-1813) by British troops, but the unhealthiness of the climate led to their withdrawal.
