After six months in New Amsterdam, Trinidad, Humboldt had examined everything that lacked the feet and the fear to run away from him. He had measured the colour of the sky, the temperature of lightning flashes, and the weight of the hoarfrost at night ... [he] dug holes, dropped thermometers on long threads down wells, and put peas on drumheads. The quake would certainly begin again, he said cheerfully. Soon the whole town would be in ruins. (p. 56)
