coast generally, but more especially in the Delta of the Niger, 
where the exciting causes of disease are to be regarded as acting 
with increased energy, and all possible means are to be used for 
obviating their injurious effects. 
It is to be hoped that the climate above the Delta will be found 
to be such as will admit of this restriction being modified. 
X. — Boats or canoes going alongside their o’wui or other vessels, 
are to be directed to take the shady side, in order to avoid, as 
much as possible, the exposure of the boats and crews to the rays 
of the sun. 
XI. — Dress . — The commanders may give permission to the 
officers of the ships under their command to w^ear uniform jackets, 
and white hats or caps on shore or on board. 
XII. — Dress. — 1. Duck frocks and trowsers are to be worn by 
the white men during the day in fine weather, with flannel next 
to the skin. Each man must also be provided with two broad 
flannel waist belts, so that he may be enabled to have a dry one 
continually round liis body. 
2. The men's hats are to be of white strawy with a padding, or 
defence of some sort under the crown, to prevent the injurious 
action of the sun’s i*ays upon the head. The white men are not 
allowed to go aloft without the officer of the watch seeing that 
they have attended to this necessarj' regulation. 
XIII. — The crews are to be mustered before sunset, when the 
white men are to be clothed in their blanket dresses for the 
night, in addition to flannel clothing underneath. 
XIV. — In case of any of the men getting wet, the officer under 
whom they have been employed is particularly charged to muster 
and report them in dry clothing, before they are allowed to go 
below. If the weather is not suitable for the clothes being hung 
in the rigging, a place on deck must be pointed out where they 
may be deposited. 
XV. — As all surfaces giving out moisture by evaporation are 
injurious to health, open vessels of water, wet clothing, officers’ 
towels, &c., should never be allowed to remain below, nor the 
crew permitted to wash themselves on the lower deck. 
XVI. — While the steam vessels of the Expedition are at 
anchor on the Coast of Africa, and in the Niger, and 
more especially in the Delta and other unhealthy places,
