young. It is however a phenomenon which is generally 
known, has often been described, and is owing to myriads 
of infused animalcule. I examined some of them taken 
in this blood-coloured water : when highly magnified, they 
do not appear larger than the head of a small pin. They 
were at first in a rapid motion, which however soon 
ceased, and at the same instant the whole animal separated 
into a number of small spherical particles. The sea has 
again assumed a reddish appearance; but this is probably 
owing to mud, that has been dissolved. We have of late 
not had any sick on board. When we were in the bay of 
Guinea, several symptoms of a -putrid fever were dis- 
covered ; but this disorder, as also a peripneumonia that 
frequently occurred, and sometimes was very violent, 
were easily cured, 
July 1st. This morning we found ourselves near the 
coast at the large mouth of the river Loango Luisa, on 
the south side of it. This river is called Caconga in the 
chart; and in the place where Loango Luisa is marked, 
no river exists. The coast before us had perpendicular 
cliffs towards the sea. Its banks consist of a reddish 
substance, which, as faras may be judged from a piece of 
about one footin length, which wastaken up with theanchor, 
is a hardened chalky clay or marl. ‘Their upper part, 
which is flat, is over-grown with scattered groups of palms 
and other solitary trees. The bay of Malambo is situated 
jower down within the banks. The harbour of Malambo, 
as also that of Cabenda, which is next to it, were formerly 
the principal trading-places of the French on this coast.
