of the numerous birds to be seen and heard, produce a healthful
influence upon the mental and physical system. The land and sea-breezes
blow regularly and constantly from half-past three o'clock P.M. till
half-past ten o'clock A.M., when there is a cessation of about five
hours till half-past three again.

Never Sultry

The evenings and mornings are always cool and pleasant, _never sultry_
and oppressive with heat, as frequently in temperate climates during
summer and autumn. This wise and beneficent arrangement of Divine
Providence makes this country beautifully, in fact, delightfully
pleasant; and I have no doubt but in a very few years, so soon as
scientific black men, her own sons, who alone must be more interested in
her development than any other take the matter in hand, and produce
works upon the diseases, remedies, treatment, and sanitary measures of
Africa, there will be no more contingency in going to Africa than any
other known foreign country. I am certain, even now, that the native
fever of Africa is not more trying upon the system, when properly
treated, than the native fever of Canada, the Western and Southern
States and Territories of the United States of America.

Dress, Avoid Getting Wet

Dress should be regulated according to the feeling, with sometimes more
and sometimes less clothing. But I think it advisable that adults should
wear flannel (thin) next to their person always when first going to
Africa. It gradually absorbs the moisture, and retaining a proper degree
of heat, thus prevents any sudden change of temperature from affecting
the system. Avoid getting wet at first, and should this accidentally
happen, take a thoroughly good bath, rub the skin dry, and put on dry
clothes, and for two or three hours that day, keep out of the sun; but
if at night, go to bed. But when it so happens that you are out from
home and cannot change clothing, continue to exercise until the clothes
dry on your person. It is the abstraction of heat from the system by
evaporation of water from the clothing, which does the mischief in such
cases. I have frequently been wet to saturation in Africa, and nothing
ever occurred from it, by pursuing the course here laid down. Always
sleep in clean clothes.

Sanitary Measures

I am sure I need inform no one, however ignorant, that all measures of
cleanliness of person, places, and things about the residences,
contribute largely to health in Africa, as in other coun
