Laid out on the platform, it struggled, tried to turn itself by convulsive movements, and made so many efforts, that one last turn had nearly sent it into the sea. But Conseil, not wishing to let the fish go, rushed to it, and, before I could prevent him, had seized it with both hands. In a moment he was overthrown, his legs in the air, and half his body paralysed, crying— “Oh! master, master! help me!” It was the first time the poor boy had spoken to me so familiarly. The Canadian and I took him up, and rubbed his contracted arms till he became sensible. The unfortunate Conseil had attacked a cramp-fish of the most dangerous kind, the cumana. This odd animal, in a medium conductor like water, strikes fish at several yards’ distance, so great is the power of its electric organ, the two principal surfaces of which do not measure less than twenty-seven square feet. The next day, April 12th, the Nautilus approached the Dutch coast, near the mouth of the Maroni. There several groups of sea-cows herded together; they were manatees, that, like the dugong and the stellera, belong to the sirenian order. These beautiful animals, peaceable and inoffensive, from eighteen to twenty-one feet in length, weigh at least sixteen hundredweight. I told Ned Land and Conseil that provident nature had assigned an important role to these mammalia.
