medicine ; a good night’s repose doing as much to- 
wards restoration to health as diet. 
As soon as favourable remissions came on and the 
tongue tolerably clean, the disulphate of quinine was 
most serviceable ; and from subsequent experience, we 
believe, that if used boldly and in full doses, it may 
be used most beneficially at a much earlier stage. In 
the secondary attacks of pure remittent fever, which 
we witnesed on our subsequent visit to the Bights and 
Fernando Po, it was given in cases where the tongue 
was even foul and dry, in doses of six to ten grains 
once or twice daily, and it acted more like a specific

Judging from the experience of the two expeditions, 
we find that, irrespective of season, the river fever, 
from whatever cause, will develope itself about the 
fifteenth day. Thus the ‘ Quorra’ and ‘ Alburkah’ in 
1832, commenced the ascent on the 28th October, and 
on the 11th November the disease manifested itself ; 
while in the last expedition, the vessels began their
