Professor Agassiz, who has been lecturing on the zoology of

South America in New York, says that the Amazon has not one fish in common with other fresh-water basins ; that in a little pool of a few hundred square yards he found 200 different kinds of peculiar fish,—three times as many as in the whole waters of the Mississippi. In the Amazon itself he found 2,000 different kinds, of which be knew only 150 before he began his investigation. He found one fish that could not only creep on land,—he had found it five miles inland,—but climb trees, and he had brought down a fish and a bird by the same shot.
