. . . said to enjoy more robust health and perform more work,
under certain precautions as to health, than natives. Actual experience in Jamaica under the
direction of Capt. Marryatt, and in Africa under Dr. Livingston, the great explorer,
has proved the ability of northern men to withstand the most deadly of the
tropical miasmata. Capt. Marryatt,
demonstrated the utility of wearing flannel next the skin. Dr. Livingston proved the value of quinine as
a prophylactic. At Port Royal our troops
use quinine with whisky, in the proportion of two grains of powdered quinine dissolved
in half a gill of whisky, diluted with half a gill of water. This is taken in the morning before eating,
and again at night, by troops exposed to malaria, and it is said that so far
from promoting intemperance it really gives a distaste for intoxicating drinks.
