the effects of the unwholesome districts through which you will 
pass, and the known skill of your medical officers, and the pru- 
dent precautions recommended in the enclosed letter from the 
Inspector-General of Naval Hospitals, it is probable that the 
sudden change of climate, with other local causes, will more or 
less affect the health of many individuals of the Expedition ; and 
to this subject we especially direct your most scrupulous atten- 
tion. In the event of anything like the ap]>earance of contagious 
or endemic disease, you will form proper establishments by 
which the sick may be immediately separated, and where unre- 
mitting attendance may be given to them ; or it may be expe- 
dient to construct temporary quarters for them on shore in some 
dry and cool place, — or in an extreme case, perhaps, it might be

Whenever you may have occasion to go out of the Quorra, 
either to visit its other branches, through the delta, or to ad-

remit your stores and provisions at Fernando Po } and when you 
have brought this service to a final conclusion, you will proceed 
there, and should you not find at that place any instructions 
from us to the contrary, you will return to England with the 
vessels under your orders, and on your arrival repair without 
delay to this office, in order to lay before us a full account of 
your proceedings, bringing with you the logs and journals of all 
the officers and other persons on board the several steam-vessels, 
together with all charts, drawings, and observations made whilst 
up the Niger, which you are hereby instructed to demand from 
them, and which are all to be scaled up, and afterwards to be 
disposed of as we may think proper to determine. 
If, however, it should appear to you that the intentions of 
Her Majesty's Government would be more fully carried out by 
returning to England yourself, or sending home another officer, 
leaving behind one or more of the steam-vessels, you are to use 
your discretion on this point, taking such steps as you may deem 
advisable for the health of the officers and crew, by sending 
them to Ascension, or to any other place which you may deem 
more advisable, until the commencement of the ensuing healthy
