430 Capt. Sabine on the Stream of the River Amazons 
of the continent of South America; where it is again sub- 
divided by the projecting part of the coast between Cape St. 
Roque and Cape St. Augustin, the northern branch coasting 
the north of Brazil and Guiana to the West Indies, and the 
southern branch proceeding down the eastern side of the con- 
tinent towards Terra del Fuego. ‘The Pheasant’s experience 
corresponded in all respects with this general view. ‘The di- 
rection of the southern part of the Equatorial stream, into 
which she entered on the 13th of July, became gradually more 
and more to the southward of west on approaching the con- 
tinent; being due west between the longitudes of 22°} and 26°; 
S. 82 W. between 26° and 29°; and S. 71 W. between 29° 
and 33°; and the apparent set between the noons of the 16th 
and 17th of July is obviously compounded of the influence of . 
the Equatorial stream (then probably become still more south- 
wardly) during the first part of the twenty-four hours, and of 
the northerly current, during the latter part, which the obser- 
vations between Bahia and Pernambuco show te prevail in the 
vicinity of the coast included between those stations. The 
Pheasant may, therefore, be considered to have crossed the 
whole breadth of the branch of the stream which proceeds to . 
the S.W., by having passed out on its western side between 
the longitudes of 33° and 36°, and to have ascertained its ge- 
neral velocity to have exceeded half a mile an hour, by the 
according observations of the 14th, 15th, and 16th of July. 
From Pernambuco to Cape St. Roque, the northerly cur- 
rent rapidly accelerated, until in passing the Cape it may be 
considered that the Pheasant had entered the full stream of 
the other branch of the Equatoria] current; namely, of the one 
which pursues its way along the northern coast of Brazil and 
Guiana to the West Indies. 
Between the noons of the 16th and 17th, she was set 44°5 to 
the north, and 425 to the west, making a general effect in the 
twenty-four hours of N. 44 W., 62 miles; but as shedid not round 
Cape St. Roque until midnight, the course having been altered 
for that purpose at half-past eleven P.M., it must be understood 
that the direction of the current was probably more northerly in 
the first part of the interval, and more westerly in the latter 
part, than the general effect; and that the velocity may in like 
manner have been less than the rate of 62 miles to the south 
of Cape St. Roque, and more than that amount after passing 
the Cape. The purpose of stopping at Maranham, obliged 
the Pheasant to draw nearer the land on the following day, 
than would have been expedient, had she been bound direct 
to the West Indies, and been desirous of preserving the full 
advantage of the current in her favour; on examination of the 
tabular
