The famous sleeping sickness, the scourge of Africa, is more frequent among natives than among the Americo-Liberians, but it has long been known in that region. The list sounds like a long and dreadful one, but is, after all, far from appalling. Dr. Lugenbeel says: “Some other diseases, which are common to most countries, may be occasionally observed in Liberia; but the variety is much less than in the United States; and except in some old chronic affections, in broken down constitutions, convalescence is generally much more rapid; in consequence of the less violence of the attack. Among the many attacks of fever, which I experienced, I never was obliged to remain in my room more than a week, at any one time; and I very seldom was confined to my bed longer than twenty-four hours. The danger in new-comers generally consists more in the frequency than in the violence of the attacks of sickness. And the majority of colored immigrants, who have sufficient prudence to use such means for the preservation of good health in Liberia as enlightened judgment would dictate, usually enjoy as good health, after the first year of their residence, as they formerly enjoyed in the United States. In some cases, indeed, the state of the health of the immigrant is decidedly improved by the change of residence from America to Africa.” In another place, he says: “In some cases, persons who might have enjoyed tolerable health in the United States, die very soon after their arrival in Liberia, in consequence of the physical system not being sufficiently vigorous to undergo the necessary change, in order to become adapted to the climate. Hence the impropriety of persons emigrating to Liberia whose constitutions have become much impaired by previous diseases, by intemperance, or otherwise. And hence the necessity of missionary societies being careful to guard the physical as well as the moral qualifications of persons who offer themselves as missionaries to Africa.”
