Piedro de Cintra, having determined to proceed no farther, returned back to Portugal from Cape Misarado, to which he had traced the coast of Africa from the Rio Grande. Upon his return, this negro who had been detained off Cape Misurado, was examined by several Negroes, and at length was understood by a Negress who belonged to an inhabitant of Lisbon; not indeed by his own proper language, but by means of another which was known to them both. Whatever intelligence may have been procured on this occasion, was not made public, except that there were unicorns in his country. After this Negro had been kept for some months in Lisbon, and had been shewn many of the curiosities of Portugal, the king ordered him to be supplied with clothes, and sent him back in a caravel to his own country. But from that coast no other ship had arrived before my departure, which was on the first of February 1463.
 For this exordium or introduction, we are indebted
to the editor of
Astley’s Collection of Voyages and Travels, said to have been a Mr
John Green. The infant Don Henry of Portugal died in 1463; so that
there must have been an interval of six or seven years between the
second voyage of Cada Mosto and this of Piedro de Cintra: Though de
Faria seems to put this voyage as having been executed before the
death of that excellent prince, yet Cada Mosto, who then actually
resided at Lagos, could not be mistaken is this important particular.—
 In a note to the second voyage of Cada Mosto,
it has been already
noticed that he seems to have given the name of Rio Grande to the
channel between the Bissagos islands, or shoals of the Rio Grande and
the Main. This river Besegue, may possibly be the strait or channel
which divides the island named particularly Bissagos, or more properly
Bissao, from that of Bassis or Bussi. Yet, this river Besegue may even
have been that now called Rio Grande, in which, about twenty-four
leagues above its mouth, there is an island called Bissaghe.—E.
 It is strange that the Rio de Nuno, close by this
cape, the estuary
of which is not less than seven or eight miles wide, should be here
omitted; but the present voyage is very superficially narrated
 The text is here obviously defective, as no river
is mentioned before;
but the allusion must be to the river Pongo, Pongue, or Pougue, at the
mouth of which Cape Sagres is situated; indeed that cape seems to be
formed by one of the islands off the mouth of the river.—E.
 There are a number of small rivers on the coast,
between Cape Sagres
and Cape Tagrin, such as Tofali, Dania, Buria, Berrea, Tanna, Pogone,
Cagrance, dos Casas; but our modern charts have none named as in the
text on this part of the coast.—E.
