ABSTRACT
The Beagle sailed from the Rio Plata, never again to enter its muddy stream. Several times when the ship has been some miles off the mouth of the Plata, and at other times when off the shores of Northern Patagonia, they have been surrounded by insects. On another occasion, when seventeen miles off Cape Corrientes, the author had a net overboard to catch pelagic animals. On several occasions, when the vessel has been within the mouth of the Plata, the rigging has been coated with the web of the Gossamer Spider. One day, at St Fe, he had a better opportunity of observing some similar facts. As they proceed further southward, the sea is seldom phosphorescent; and off Cape Horn, he do not recollect more than once having seen it so, and then it was far from being brilliant. On the coast of Patagonia. The creek runs for about twenty miles inland, with an irregular width.
