Harvey shows the instinct of a naturalist in the following account of the cassowary which was not only new to him, but was unknown to Europe at the time he wrote. He says: "A certain bird, as large again as a swan, which the Dutch call a cassowary, was imported no long time ago from the island of Java in the East Indies into Holland. Ulysses Aldrovandus gives a figure of this bird and informs us that it is called an emu by the Indians. It is not a two-toed bird like the ostrich but has three toes on each foot, one of which is furnished with a spur of such length, strength, and hardness that the creature can easily kick through a board two fingers' breadth in thickness. The cassowary defends itself by kicking forwards. In the body, legs, and thighs it resembles the ostrich: it has not a broad bill like the ostrich, however, but one that is rounded and black. On its head by way of crest it has an orbicular protuberant horn. It has no tongue and devours everything that is presented to it--stones, coals even though alight, pieces of glass--all without distinction. Its feathers sprout in pairs from each particular quill and are of a black colour, short and slender, and approaching to hair or down in their character. Its wings are very short and imperfect. The whole aspect of the creature is truculent, and it has numbers of red and blue wattles longitudinally disposed along the neck. "This bird remained for more than seven years in Holland and was then sent among other presents by the illustrious Maurice Prince of Orange to his Serene Majesty, our King James, in whose gardens it continued to live for a period of upwards of five years."
