On my second visit to Havana in 1804 (139) I could not return to the Batabanò ciénaga and so I had these two species brought to me at great expense. Two crocodiles arrived alive. The eldest was 4 feet 3 inches long. They were captured with great difficulty and arrived on mules with their snouts muzzled and bound. They were lively and ferocious. In order to observe them we let them loose in a great hall, and from high pieces of furniture watched them attack large dogs. Having lived on the Orinoco, the Apure and the Magdalena for six months among crocodiles we enjoyed observing this strange animal before leaving for Europe, as they change from immobility to frenzied action quite suddenly. I counted thirty-eight teeth in the upper jaw and thirty in the lower. In the description that Bonpland and I made on the spot we deliberately marked that the lower fourth tooth rises over the upper jaw. The cayman sent from Batabanò died on the way and stupidly was not brought to us, so we could not compare the two species.
