Of the five Foraminifera of Cape Horn, four are peculiar 
to the Fauna of the Atlantic Ocean. Of these four, two are 
frequent in the Malvinas, without extending to the northern 
coasts of Patagonia; one occurs on the coast of Patagonia, 
without presenting itself in the Malvinas; and one is common 
to both localities. We thus see that the Foraminifera of Cape 
Horn are distributed through the Atlantic Ocean, because they 
follow the direction of the currents. 
In the Malvinas there are thirty-eight species, a high num- 
ber when we take into consideration the southern position 
and the low temperature of these islands; and this is a proof 
that the Foraminifera can live and multiply in all parts of the 
earth, and in all temperatures, if the locality be favourable. 
Of these thirty-eight species, only five are found on the coast 
of Patagonia, near the Rio Negro. This might appear singu- 
lar, did we not know that the currents which proceed from 
Cape Horn diverge not a little towards the southern portion 
of America, so that one of the two branches follows the coasts 
of the continent, while the other traverses the Malvinas, and 
in this way the water which washes these islands does not 
again come in contact with the coasts of the continent. Hence 
it follows that the Malvinas and Patagonia can have in com- 
mon only the species distributed over all coasts, while the 
Malvinas can possess their peculiar species, which are distinct
